Smartphones have revolutionized our lives, and you&#8217;re likely reading this on one. It&#8217;s hardly shocking to consider how pervasive mobile gadgets have become. Nearly half of people polled in a February 2021 survey conducted by L.Ceci via Statista spent five to six hours a day on their phones, not considering work-related smartphone use.&nbsp;



Mobile devices handle more than half of all searches worldwide. Additionally, page speed is becoming a factor in mobile search engine rankings. Companies and bloggers must opt for a website theme that has been developed and optimized for speed.



This means if your website is not mobile-friendly,&nbsp; you are missing more than half of your potential customers. It also implies that your website&#8217;s design and navigation must be consistent across all platforms and devices



This is where the ultimate responsive website design testing comes in. It ensures that your website displays correctly and functions smoothly on any computer, laptop, tablet, or smartphone. The most accessible approach to ensure that you execute responsive design testing successfully is to follow a responsive design testing checklist, and in this article, we have done the hard work for you.

<h2 id="h-what-is-responsive-web-design">What Is Responsive Web Design? </h2>



Nowadays, people use various gadgets to access the internet and interact with websites. You can find these high-tech gadgets in multiple form factors and display sizes. Your site&#8217;s design and functionality must adapt to the screen size of every visitor accessing it.&nbsp;



Responsive web design helps your site display correctly on all screen sizes and resolutions. This layout method adjusts the content&#8217;s visibility, size, and position in response to the viewing device, ensuring optimal readability and viewing experience across all devices.&nbsp;Later, you may use a<a href="https://venngage.com/features/poster-maker" target="_blank" rel="noreferrer noopener nofollow"> free poster maker</a> to create banners if you&#8217;re getting into traditional ads, but you should still follow your brand guidelines.



Conversely, your rivals are rolling out the red carpet for potential clients. Currently, smartphones are widely available, with 80 percent of internet users having one. Users in this demographic often devote 69% of their media consumption habits to their mobile devices. Without a mobile-friendly website, a company runs the danger of losing sales. Furthermore, about  57% of consumers said they wouldn&#8217;t suggest a firm with poorly designed websites also <a href="https://taggbox.com/blog/embed-youtube-shorts-on-website/" target="_blank" rel="noreferrer noopener nofollow">embed YouTube shorts</a>, TikTok videos, and Instagram reels to make it more responsive to increase retention time. 



This shows the value of responsive web design, and if you care about keeping your audience and your business alive, you should seriously consider investing in it.



<h2 id="h-ultimate-checklist-for-responsive-design-testing">Ultimate Checklist For Responsive Design Testing</h2>



A responsive design should already be live on your website if you&#8217;ve updated it or gotten a new one during the past several years. A website that adapts to different devices&#8217; screen sizes is now expected of users; hence most web design firms include responsive design in their primary offerings. However, optimizing your website for mobile devices isn&#8217;t a one-and-done deal.



Your website&#8217;s responsiveness should be tested with a responsive design checker and regularly updated per your responsive design testing checklist. 



<h3 id="1-test-for-navigation-on-website">1. Test For Navigation On Website </h3>



Use a navigation bar to direct visitors to certain parts of your site or specific pages. There are usually five or more buttons on a navigation bar. The menu bar must evolve with the device. No matter how much we tried to make the navigation bar smaller using the @media queries meta tag, it still wouldn&#8217;t be clickable on a mobile device. So, we&#8217;ve found that the &#8220;hamburger menu&#8221; works well on mobile devices. Because of its widespread use, users will actively seek it out if they have no choice.&nbsp;



It should be standard practice to confirm that the navigation layouts work correctly across devices to ensure a positive user experience.



<h3 id="2-perform-font-device-testing">2. Perform Font Device Testing </h3>



Developers will often employ a wide range of typefaces and design approaches while composing text for a website to make it more aesthetically pleasing to the users. Devices that do not support these fonts, or use a different encoding system, may display them as gibberish. It is, thus, vital to test the typefaces on various devices before releasing them for actual website <a href="https://testsigma.com/blog/mobile-responsive-testing/" target="_blank" rel="noreferrer noopener">mobile responsive testing</a>. 



<h3 id="3-third-party-browser-and-device-testing">3. Third-Party Browser and Device Testing </h3>



You should use Google Analytics data to examine online and mobile traffic, considering the browsers and devices used to access the sites. This should be done quarterly, with the latest OS and device and the old ones phased out. Consider including the beta versions to ensure your website is mobile-friendly.&nbsp;



<h3 id="4-conduct-a-test-on-a-small-screen">4. Conduct a Test on a Small Screen </h3>



With the constantly growing number of mobile users, having a website that doesn&#8217;t adjust to any screen size is no longer acceptable. That&#8217;s why keeping the <a href="https://testsigma.com/blog/mobile-first-design/" target="_blank" rel="noreferrer noopener">mobile-first design</a> strategy in mind when creating a responsive layout is crucial. Mobile phones and other small display devices should be a starting point for your design.



<h3 id="5-test-how-fast-your-website-is">5. Test How Fast Your Website Is </h3>



You can track how well your components adapt to different screen sizes with responsive design. However, when considering mobile devices, which often operate on lower bandwidth, it becomes clear that rich content, such as photos, videos, etc., poses the greatest threat to the site&#8217;s loading speed. The loading time will grow proportionally if we keep using the same graphics we were producing on larger devices like laptops, which will frustrate your users.&nbsp;



A mobile web page should only take four seconds to load. After two seconds, if your loader is still spinning, users will likely hit the back button.&nbsp;



Web page load times can negatively affect even the most well-known companies. To paraphrase current findings from Hubspot&#8217;s research:



<ul><li>Yahoo may see a boost of 9 percent in visitors if the company can shorten the time it takes pages to load by 0.4 seconds.&nbsp;</li><li>Amazon will lose $1.6 billion annually in sales should page load times increase by just one second.</li><li>A 2. the second delay in Bing&#8217;s search results would result in a 4.3% drop in revenue per visitor, a 3.75 % drop in clicks, and a 1.8% drop in queries.</li></ul>



If your website loads slower than you&#8217;d like on these smaller devices, you may need to employ different strategies to present the same graphics.



<h3 id="6-test-element-alignments">6. Test Element Alignments</h3>



When working with limited space, element alignment becomes especially crucial. Everyone can readily identify a shape that is out of proportion and breaks the limits. The tester must verify that the website&#8217;s many parts are spaced adequately across the screen. Responsive web design will not be effective if it is not rendered and aligned correctly.&nbsp;



<h3 id="7-test-for-content-placement">7. Test For Content Placement</h3>



The larger viewing area of a desktop or laptop computer makes it simple to zero in on a specific component. In addition, because of the viewer-to-screen distance, we can examine every detail. However, mobile devices are an exception to this rule. Because of the limited real estate screen on mobile devices, we must be mindful of condensing unnecessary information. See below for a representation of where your attention should be drawn on a mobile device&#8217;s display:



<ul><li>Edges, Corners (Least Precise)&nbsp;</li><li>Center (Most Precise)&nbsp;</li></ul>



Determine if the location of the critical elements is inside this area and if the elements are not overly crowded. You can use <a href="https://www.founderjar.com/web-based-project-management-software/" target="_blank" rel="noreferrer noopener nofollow">web-based management software</a> to plan and manage your content placement.&nbsp;



<h3 id="8-perform-compatibility-testing-across-multiple-browsers">8. Perform <a href="https://testsigma.com/guides/compatibility-testing/" target="_blank" rel="noreferrer noopener">Compatibility Testing</a> Across Multiple Browsers</h3>



The first thing you should do when testing a website for responsive design is to use a different browser on the device to see if it displays correctly. When you perform <a href="https://testsigma.com/blog/cross-browser-compatibility-testing-what-browsers-you-should-test/" target="_blank" rel="noreferrer noopener">cross-browser compatibility testing</a>, your website may be viewed and explored in any browser, operating system, or resolution. Manual and automated <a href="https://testsigma.com/cross-browser-testing" target="_blank" rel="noreferrer noopener">cross-browser testing</a> is under the broader umbrella, and both have several sub-paths. <a href="https://testsigma.com/blog/remote-usability-testing/" target="_blank" rel="noreferrer noopener">Remote Testing</a> of Websites provides additional details on the same topic. 



Our knowledge tells us that <a href="https://testsigma.com/cross-browser-testing-tools" target="_blank" rel="noreferrer noopener">cross-browser testing tools</a> hosted in the cloud are among the most effective of their kind. Cloud-based solutions don&#8217;t require the installation of any testing infrastructure, can be accessed from anywhere, and are easy to learn and use.&nbsp;



<h3 id="9-test-for-interactive-experience">9. Test For Interactive Experience </h3>



We&#8217;ve already established a wide range of screen sizes for mobile devices. There&#8217;s also the fact that the interactive experience has evolved since Steve Jobs unveiled the original iPhone. Some individuals today choose to use a stylus for a more consistent and accurate touch, while others prefer to use one hand exclusively for most interactions with the device. The primary goal of this responsive design testing checklist is to ensure a consistent user experience across devices and interaction types. 



You shouldn&#8217;t be able to press two buttons simultaneously with one hand on the same button. The user interface should attempt to consolidate the available choices by providing several different models, etc. The user&#8217;s impression of our site depends on this, so our responsive design testing checklist must remain a top priority.



<h3 id="10-test-the-mobile-compatibility-of-website-pop-ups">10. Test the Mobile Compatibility of Website Pop-ups </h3>



Everybody is utilizing pop-ups because they are so effective at getting visitors to sign up for newsletters and buy products. However, you should be aware that website pop-up windows can be helpful and annoying. It can be highly irritating to site users and harmful to your site&#8217;s reputation with search engines if it is not presented correctly.&nbsp;



You should also check if the website&#8217;s pop-ups are responsive—all pop-ups, whether online or in a new window, are included. Pop-ups should also be responsive to their purpose on any device and pass a responsive design test.&nbsp;



<h3 id="11-test-for-better-functionality">11. Test for Better Functionality. </h3>



Check that your menu bars don&#8217;t spill off the sides of the screen. On mobile devices, tap the hamburger menu icon to access the site&#8217;s hidden navigation. Verify that swiping is an option for the user.&nbsp;



<h2 id="h-tools-for-responsive-design-testing">Tools For Responsive Design Testing</h2>



It would help if you had a thorough <a href="https://testsigma.com/blog/software-testing-strategy/" target="_blank" rel="noreferrer noopener">testing strategy</a> to ensure that your website works consistently across all platforms, browsers, and operating systems. Checking for user engagement, page loading, typefaces, graphics, navigations, alignments, etc., across several mobile devices would be a huge undertaking. Use a <a href="https://slidemodel.com/templates/tag/funnel/" target="_blank" rel="noreferrer noopener">funnel template</a> to monitor and group audience interaction with the website.&nbsp;



However, several solutions on the market make it easy to check off every item on the responsive design testing checklist. For example, <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener">Testsigma</a> is a responsive cloud-based automation tool that provides website and mobile app testing to increase speed and improve performance. The tool has many notable features, including automated maintenance, debugging, and instant reporting. If you want to test how responsive your website is, this is a great place to start.

<h2 id="h-conclusion">Conclusion </h2>



More than 8.5 billion mobile devices are currently in use worldwide; thus, your website must be optimized for mobile users. Every day, new gadgets, Operating systems, and browsers are released. However, testing a website&#8217;s responsive design is an ongoing process. Regular maintenance of the responsive design testing checklist is required.



To ensure your website is compatible with the latest devices and browsers, you should regularly update the list you test with. If you need inspiration for a new website and want to use responsive design, you can find examples of it all over the internet.&nbsp;



Remember, too, that testing for responsive design is a continuous effort, not a one-and-done task. Each day brings a slew of new gadgets, so we must keep at it.

<h2 id="73jp0">Overview of Cross Browser Testing using Selenium</h2>



It&#8217;s not fair to ask users to access your application with a specific browser. To reach out to the maximum number of users, you need to cater to all the devices and platforms they use. Since there are various web browsers in the market, the choice of usage should be left to the user. Different users use different browsers based on their comfort. It’s the job of the test engineer to ensure that the application works well on all the widely used browsers. This urges the need for testing the application code on different platforms. This is where <a href="https://testsigma.com/cross-browser-testing" target="_blank" rel="noreferrer noopener">cross browser testing</a> comes into the picture, the type of testing which verifies that a website works accurately in all browsers. 



The main goal is to verify that the website you’re developing runs perfectly on all targeted browsers and operating systems. Testers can either run manual tests or use automated tools like Selenium WebDriver. It helps save you time, as you need not reinstall your browsers multiple times.



<h2 id="9o12o">Cross Browser Testing using Selenium</h2>



As mentioned earlier, Selenium is the most popular automated testing tool for various functions. Browser testing is one of the many features supported by Selenium.



<ol type="1"><li>Selenium WebDriver enables you to automate test cases on Internet Explorer, Firefox, Chrome, and Safari browsers.</li><li>You can integrate the TestNG framework with Selenium WebDriver to run your test cases on different browsers.</li><li>You can analyze performance for cross-browser compatibility.</li></ol>



Read on <a href="https://testsigma.com/blog/selenium-based-automated-testing/" target="_blank" rel="noreferrer noopener">Selenium Based Automation Testing</a> to gain deeper insights into the various components of Selenium.



Next, let’s see how to perform cross browser testing using Selenium.



<h2 id="a85to">How to Perform Cross Browser Testing using Selenium?</h2>



Let’s write a simple code to understand how it works.



<h4 id="5v555">Requirements:</h4>



<ol type="1"><li>Java Installation</li><li>Integrated Development Environment (IDE) installed. In this case, let’s use Eclipse IDE</li><li><a href="https://www.selenium.dev/downloads/" target="_blank" rel="noreferrer noopener">Selenium Server</a> Configuration</li><li>TestNG integration</li><li>Browser Drivers for Chrome, Firefox, Edge, etc.</li></ol>



<h4 id="e0jm7">Flow:</h4>



In the below program, let’s log in to the <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener">Testsigma</a> website.



The task here is to check for cross-browser compatibility on 3 different browsers. They are Google Chrome, Mozilla Firefox, and Microsoft Edge. To do this, let’s set the system properties for all the 3 browsers as shown below. Finally, using locators allows you to perform actions on the website.



<h4 id="1tr63">Code:</h4>



<pre class="wp-block-code"><code>package test;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.edge.EdgeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;</code></pre>



<pre class="wp-block-code"><code>public class TestScript {
WebDriver driver;

@BeforeTest
@Parameters("browser")
public void create(String browser) throws Exception{
//Checking for 'firefox' parameters
if(browser.equalsIgnoreCase("firefox")){
//creating firefox instance
System.setProperty("Add the path to the firefox/gecko driver");
driver = new FirefoxDriver();
}
//Checking for 'chrome' parameters
else if(browser.equalsIgnoreCase("chrome")){
//Creating chrome instance
System.setProperty("Add the path to chrome driver");
driver = new ChromeDriver();
}
else if(browser.equalsIgnoreCase("Edge")){
//Creating edge instance
System.setProperty("Add the path to edge driver”);
driver = new EdgeDriver();
}
else{
//If the browser is not passed then throw the below exception
throw new Exception("Invalid browser");
}
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
@Test
public void testParameterWithXML() throws InterruptedException{</code></pre>



<pre class="wp-block-code"><code>driver.get("https://www.testsigma.com");
WebElement Signin = driver.findElement(By.linkText("Login"));
//Hit login button
Signin.click();
Thread.sleep(4000);
WebElement uname = driver.findElement(By.id("loginUsername"));
//Fill user name
uname.sendKeys("your email id");
Thread.sleep(4000);
WebElement pwd = driver.findElement(By.name("password"));
//Fill password
pwd.sendKeys("your password");
Thread.sleep(6000); 
WebElement = driver.findElement(By.linkText("SIGN IN));
//Hit search button
Next.click();
}</code></pre>



<pre class="wp-block-code"><code>@AfterTest
public void quit(){
driver.close();
}
}</code></pre>



To execute the above test script, you need a TestNG XML file that contains the dependencies of the above class file. In this case, I have created an XML file to reference the above parameters.



<pre class="wp-block-code"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"&gt;
&lt;suite name="TestSuite" thread-count="2" parallel="tests" &gt;
&lt;test name="ChromeBrowser_Test"&gt;
&lt;parameter name="browser" value="Chrome"/&gt;
&lt;classes&gt;
&lt;class name="test.TestScript"&gt;
&lt;/class&gt;
&lt;/classes&gt;
&lt;/test&gt;
&lt;test name="FirefoxBrowser_Test"&gt;
&lt;parameter name="browser" value="Firefox" /&gt;
&lt;classes&gt;
&lt;class name="test.TestScript"&gt;
&lt;/class&gt;
&lt;/classes&gt;
&lt;/test&gt;
&lt;test name="EdgeBrowser_Test"&gt;
&lt;parameter name="browser" value="Edge" /&gt;
&lt;classes&gt;
&lt;class name="test.TestScript"&gt;
&lt;/class&gt;
&lt;/classes&gt;
&lt;/test&gt;
&lt;/suite&gt;</code></pre>



On executing this code as TestNG Test, browser drivers will instantiate the respective browsers and perform the login action on the Testsigma website.



This is how it works. Now let us understand how Testsigma eases the process of writing automated test code.



<h2 id="best-practices-to-do-cross-browser-testing-in-selenium">Best Practices to do Cross Browser Testing in Selenium</h2>



Here are some recommended best practices to follow when conducting cross-browser testing with Selenium:



<ol><li>Be careful when selecting libraries and frameworks: The most recent CSS or JS frameworks might not be compatible with all browsers. This is important to remember while creating web apps because browsers have various rendering engines. Before using these libraries or frameworks, check browser recommendations to discover if they support them.</li><li>Employ relevant JavaScript libraries and task runners: Because JavaScript is a crucial component of web app development, it is critical to employ the appropriate JavaScript resources that fulfill site needs and provide consistent browser compatibility.</li><li>Identify and analyze your browser&#8217;s OS configuration: To do effective cross-browser testing with Selenium, you must know the required browser versions and operating systems. We recommend prioritizing combinations likely to be used by the largest segments of your audience.</li><li>Optimized for Internet Explorer: Internet Explorer does not support advanced CSS styles and frameworks, which can distort design elements. To solve this problem, create a separate style sheet for IE and add some hacks to the doctype.&nbsp;</li></ol>



By following these best practices, testers can ensure that their web application behaves consistently across different browsers and operating systems.&nbsp;

You can write test cases for each browser individually or use a testing framework such as TestNG to run tests on multiple browsers simultaneously. It&#8217;s crucial to ensure that your application&#8217;s functionality and user interface are consistent across all tested browsers and their versions. You can also use Selenium Grid to run your tests in parallel on multiple machines to speed up your tests. The best option would be going for an end-to-end automation platform like Testsigma.

Cross Browser Testing using Selenium WebDriver

Cross Browser Testing in Selenium WebDriver – Testsigma

To understand the difference between the Selenium Standalone server and the Selenium server, we need to go back to the Selenium history. Released in 2002, Selenium is an open-source tool, shipped with Apache Open Source License 2.0. Since web technologies have undergone many changes, automation frameworks like Selenium also had to go through changes.&nbsp;



Interestingly Selenium is the most popular automation framework today as well. Selenium has survived because it is adopting the latest technology and architecture. Every time Selenium made a new release it ensured that the framework is aligned with the latest technology trends and architecture. 



Selenium framework is designed in such a way that programming language should not be a barrier to testers as it supports Java, JavaScript, Python, C#, etc.



Many are confused that WebDriver API is a Selenium, but WebDriver is one of its components. Selenium has multiple components such as Selenium IDE, Selenium Grid, Selenium WebDriver, etc. As Selenium is the most flexible automation framework, it provides support to local execution, remote execution, and recording of the scripts.

<h2 id="h-difference-between-selenium-standalone-server-and-selenium-server">Difference between Selenium Standalone server and Selenium server</h2>



The current Selenium version is 4.x. As mentioned earlier, Selenium has undergone many changes whenever it is upgraded to a major version like 1.x, 2.x, etc. With Selenium 4.0, there is no such confusion between Selenium Server and Selenium Standalone server. The only executable server jar available is Selenium Grid.&nbsp;



This article provides concrete and definite answers to the question: Difference between the Selenium Standalone server and the Selenium server.



<h2 id="h-what-is-selenium-server">What is Selenium Server?</h2>



<a href="https://www.selenium.dev/documentation/legacy/selenium_1/" target="_blank" rel="noreferrer noopener">Selenium RC</a> was the initial and core Selenium project even before Selenium WebDriver started. The Selenium RC is deprecated and no longer supported. But to understand the difference and arrive at a definite conclusion, you need to explore the history of Selenium Versions.



Let&#8217;s understand the components of Selenium RC.



Selenium Server



The Selenium Server in Selenium RC was responsible for the below set of actions



<ul><li>Launch the browser</li><li>Interpret and run the Selenium command passed from the test program (code)</li><li>Act as an HTTP proxy by intercepting and verifying the HTTP message passed between the browsers and the Application Under Test</li></ul>



Client libraries



Client libraries in Selenium were used as the interface between each programming language and the Selenium RC Server.



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/Selenium-RC-Architecture.jpg" alt="Selenium RCArchitecture" class="wp-image-21175" width="600" height="400"/><figcaption>Selenium RC Architecture</figcaption></figure></div>



<h2 id="h-how-does-selenium-rc-selenium-server-work">How does Selenium RC/ Selenium Server work?</h2>



The above Architecture&nbsp; diagram shows the working mechanism of the Selenium RC Server



<ul><li>Selenium Client Libraries communicate with the Server by passing the Selenium command for execution one by one</li><li>The server passes the Selenium command to the browser using Selenium Core</li><li>The browser executes the Selenium command</li></ul>



Since the Selenium Server is in context, it existed in Selenium RC, which was the initial version of Selenium. The Selenium Server was one of the key components in Selenium RC. It receives Selenium commands from the test program, interprets, and reports back to your program; the results of running those tests, and tests are then marked as pass or fail.



The Selenium Server was designed to receive the Selenese commands from your test script. The communication was done using the simple HTTP protocol, either GET or POST methods. This method enables support for multiple programming languages. Any programming language supporting HTTP calls can be used to communicate with the Selenium Server.



<h2 id="h-sample-selenium-server-rc-script">Sample Selenium Server RC script.</h2>



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;public class NewTest{



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; public void testNew() throws Exception {



Selenium Selenium = new DefaultSelenium(&#8220;localhost&#8221;, 4444, &#8220;firefox&#8221;, &#8220;https://google.com&#8221;)



Selenium.start



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selenium.open(&#8220;/&#8221;);



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selenium.type(&#8220;q&#8221;, &#8220;Testsigma&#8221;);



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selenium.click(&#8220;btnG&#8221;);



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selenium.waitForPageToLoad(&#8220;30000&#8221;);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}



The Selenium RC Server architecture was different from the latest Selenium, so the above code is comparatively different from today&#8217;s Selenium Code.



The DefaultSelenium was part of package com.thoughtworks.Selenium in Selenium RC which was used for Initialising the Selenium.



Selenium 2.x introduced the Selenium <a href="https://www.selenium.dev/documentation/legacy/selenium_2/upgrading/" target="_blank" rel="noreferrer noopener">WebDriver API</a>, which removed the complexity of the Selenium RC server. In Selenium RC, the Selenium Server was the mediator between the Selenese command and the browser. The WebDriver was built with new architecture, it does the job similar to Server (not the same); however, WebDriver is not a server. WebDriver makes use of native events to interact with a web page.



Before we explore about Selenium Standalone Server, let&#8217;s conclude the Selenium Server



<ul><li>The Selenium Server was part of the Selenium RC.</li><li>Selenium Server acts as the mediator between the Selenium commands and the browser.</li><li>Selenium Server communicates with the client using HTTP calls such as GET/POST.</li><li>The Selenium Server is deprecated; it is no longer available.</li><li>The Selenium WebDriver replaced the Selenium Server.</li></ul>



<h2 id="h-why-is-selenium-server-selenium-rc-deprecated">Why is Selenium Server/Selenium RC deprecated?</h2>



The Selenium Server/RC had limitations, so the Selenium team decided to introduce a WebDriver and bring the changes to the architectural level.&nbsp;



Some of the challenges with Selenium Server/RC:



<ol><li>Selenium RC architecture was complex.</li><li>Selenium Server needed to start before test execution.</li><li>Selenium RC doesn&#8217;t support headless mode.</li><li>Supporting multiple browsers for a long period was challenging.</li></ol>



Now, let&#8217;s learn about Selenium Standalone Server.



<h2 id="h-what-is-selenium-standalone-server">What is Selenium Standalone Server?</h2>



The Selenium Standalone Server is what you see as a Selenium Grid today. But you may be wondering: Why do we still need a Selenium Standalone Server when Selenium Server was replaced with WebDriver in Selenium 2?



Replacing Selenium Server with Selenium WebDriver solved the problem of local execution. Using WebDriver, you do not need to start the Selenium Server as WebDriver communicates to the browser directly without starting the <a href="https://www.redswitches.com/dedicated-server-hosting/" target="_blank" rel="noreferrer noopener">dedicated server</a>. However, there are some use cases where you need to use the server. Some common scenarios are



<ol><li>If you want to Execute your test on the remote machine</li><li>If you want to distribute tests across the multiple machines</li></ol>



Earlier, the Selenium was shipped with a standalone server, though it was optional. The Selenium Standalone server had the format of <a href="https://selenium-release.storage.googleapis.com/index.html?path=2.39/" target="_blank" rel="noreferrer noopener">Selenium-server-standalone-{version}.jar</a>.&nbsp;



The Selenium 4.0 doesn&#8217;t follow the above format; it follows the format of Selenium-server-{version}.jar. The Selenium Standalone server is optional. You need to use the Selenium Standalone server or Selenium Grid only when you have the above use cases.



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/Selenium-Grid-Architecture-in-Selenium-4-Grid4.jpg" alt="Selenium Grid Architecture in Selenium" class="wp-image-21170" width="600" height="400"/><figcaption>Image: Selenium Grid Architecture in Selenium 4 (Grid4)</figcaption></figure></div>



Not to confuse other sources on the internet, the Selenium Grid has undergone many changes over the versions. For example, the Selenium Grid 2 and 3 had different architecture than the Selenium 4 Grid.



The Selenium Grid 3 had Hub and Node architecture, where the hub was a central system to communicate with the Nodes. The Node was the system where the actual browser runs.



The Selenium 4 Standalone Server or simply Selenium Server (in Selenium 4)&nbsp; has the above architecture.



Router: Entry point of Grid, receives all external requests and forwards to Node with the help of Session map and Session Queue.



Distributor: It keeps all the Node details,&nbsp; such as a list of browsers, available node slots, etc.



Node: Node is the place where the actual browser exists. Each grid can have multiple Nodes. The distributor will have every Node&#8217;s information along with its capabilities. The Node&#8217;s responsibility is just to execute the commands. It doesn’t make any judgments; it simply executes the command received.



<h2 id="h-when-to-use-selenium-standalone-server-grid">When to Use Selenium Standalone server/Grid</h2>



<ul><li>To run the cross-browser and/or cross-platform tests parallely</li><li>To execute the tests faster in distributed test execution environment</li></ul>



The confusion between the Selenium Server and Selenium Standalone server arises because of Selenium RC or an older version of Selenium 4. Considering Selenium 4, there is only one Selenium Server available which is Selenium Grid Server.



Example of Selenium Code using Selenium Grid:



ChromeOptions options = new ChromeOptions();



options.setCapability(CapabilityType.BROWSER_NAME,&#8221;chrome&#8221;)&nbsp;&nbsp;



RemoteWebDriver driver = new RemoteWebDriver(new URL(&#8220;http://localhost:4444&#8221;), options);



driver.get(&#8220;https://google.com&#8221;);



driver.close();



To Summarise 



<ul><li>Selenium Server and Selenium Standalone server are different; each is designed to serve a different purpose.</li><li>Selenium Server was part of Selenium RC, which is now deprecated.</li><li>Selenium WebDriver is a replacement for Selenium RC Server with better and faster execution of tests.</li><li>The primary purpose of Selenium Standalone Server / Selenium Grid is to execute the tests in a distributed environment parallelly.</li><li>The Selenium Grid/Selenium Standalone server is still available for use with the latest version of Selenium 4.</li><li>The Selenium Grid /Selenium Standalone server is optional and can be chosen based on the requirement and purpose.</li></ul>



<h2 id="h-challenges-with-selenium">Challenges with Selenium</h2>



Though Selenium is the most popular automation framework, it requires a deep level of technical expertise. Today, there are many test automation frameworks such as Playwright, Cypress, TestCafe, WebDriverIO, etc. One of the major challenges that you and your organization face is skillset. You&#8217;ll have to learn a new API and architecture whenever you switch to a new testing framework.



<h3 id="challenges-of-selenium-and-other-test-automation-framework">Challenges of Selenium and other Test Automation Framework</h3>



<ul><li>The learning curve for every framework is considerably high.</li><li>Complicated setup, requiring a good amount of technical expertise.</li><li>Setting up a framework from scratch is different.</li><li>Testing in a cross-browser and cross-platform environment requires robust infrastructure. Maintaining the infrastructure is complicated.</li><li>Not all frameworks support multi-level testing such as API Testing, UI Testing (Visual Testing), and end-to-end Testing.</li><li>Manual Testers need to put high effort into learning automation.</li><li>Reporting and DevOps integrations are additional complications.</li><li>Whenever there is an upgrade of your tool version you need to learn and upskill. Breaking changes in the latest version may cause false failures, which in turn requires high maintenance.</li></ul>



With all these difficulties, achieving a quality product is a nightmare. Well, Testsigma addresses all these pain points. Imagine writing the test case in plain English, which executes like a charm. Testsigma is an Gen AI-powered test platform that allows you to write tests in simple English. 



Unlike Selenium, Testsigma doesn&#8217;t require any complicated setup or infrastructure management. The tests can be recorded, or you can even write your own; same tests can be executed on 800+ browsers.



<h2 id="h-features-of-testsigma">Features of Testsigma</h2>



<ul><li>Ability to record the tests or write your tests.</li><li>No coding knowledge is required, and tests can be written in plain English language.</li><li>Manual testers can quickly learn and upgrade themselves to the automation world.</li><li>Feature to Test on Mobile devices without complicated setup.</li><li>No need to maintain infrastructure; Testsigma takes care of that.</li><li>Supports multiple types of tests such as API Tests, End to End tests, and Visual Tests.</li><li>Supports all major DevOps tools.</li><li>Faster execution and instant reports and analytics,</li></ul>



In addition, Testsigma has a community-driven plugin marketplace where you can easily hook any plugins to your test.&nbsp;



Comparing Selenium and Testsigma, Testsigma can save a lot of time and effort. Selenium testers mostly spend time setting up, configuring, and debugging issues by losing the main focus of writing the automation scripts. Testsigma, on the other hand, takes all those burdens and complications of configuration and setup, enabling testers to focus on their automation script and execution happily.
