TDD vs BDD vs ATDD: Key Differences

Automating an application can be performed in various ways with various tools. Selenium WebDriver is most used among those because of being an open source and ease of use. Selenium WebDriver gives users a lot of flexibility to write their test in different programming language and allow the user to execute their test on different browser like Firefox, Chrome, Edge, Safari, etc. It can also be integrated with other 3rd party tools like TestNG, Junit, etc.&nbsp;



The login feature is a critical component of many websites. The login page is the most crucial component when developing a website. The login page also plays a vital role from a security point of view. This blog will show how easy it is to automate Login to an application using Selenium WebDriver.

<h2 class="wp-block-heading" id="h-prerequisites-for-automated-login-using-selenium-webdriver">Prerequisites for Automated Login using Selenium WebDriver</h2>



To get started with <a href="https://testsigma.com/blog/selenium-based-automated-testing/" target="_blank" rel="noreferrer noopener">Selenium</a> automation login, the following components are necessary.



<ol class="wp-block-list"><li>Download and Install JDK</li><li>Download and Install IDE (Integrated Development Environment) like Eclipse, and IntelliJ</li><li>Selenium Client Configuration</li><li>Integrate TestNG with IDE</li><li>Browser drivers for Firefox, Chrome, IE, etc.&nbsp;</li></ol>



<h2 class="wp-block-heading" id="selenium-and-selenium-webdriver">Selenium and Selenium WebDriver</h2>



<a href="https://www.selenium.dev/" target="_blank" rel="noreferrer noopener">Selenium</a> is a free, open-source automated testing framework that tests web applications across different browsers and platforms. Testing was done using Selenium, usually referred to as Selenium testing. Being an open source in nature, the Selenium framework can be integrated with other 3rd party tools.&nbsp;



Since Selenium is an open-source tool, there is no licensing cost involved, which is one of the greatest advantages over any other testing tool.



<a href="https://testsigma.com/blog/selenium-based-automated-testing/#Selenium_WebDriver" target="_blank" rel="noreferrer noopener">Selenium WebDriver</a> API provides a communication channel between languages and browsers. Selenium WebDriver is a framework that permits you to execute a cross-browser test.&nbsp;



Selenium WebDriver is an upgrade of Selenium RC. Selenium WebDriver is a bridge between the Selenium test and your browser.



Steps for Automate Login functionality



<ol class="wp-block-list"><li>Instantiate the Selenium WebDriver</li><li>Maximize the browser</li><li>Navigate to URL</li><li>Synchronization using implicit wait</li><li>Identify the web element by using locating technique of Selenium</li><li>Verification and Validation</li></ol>



Now let&#8217;s go through each step in detail:



1. Instantiate the Selenium WebDriver



Launching any web browser requires setting the driver&#8217;s path and instantiating the required browser. To instantiate the object of the browser driver, you can simply create the object with the help of the below command



For Chrome:



System.setProperty(&#8220;webdriver.chrome.driver&#8221;, &#8220;path of driver&#8221;); WebDriver driver = new ChromeDriver();&nbsp;



For Firefox:



 System.setProperty(&#8220;webdriver.gecko.driver&#8221;, &#8220;path of driver&#8221;); WebDriver driver = new FirefoxDriver();



For Edge:



System.setProperty(&#8220;webdriver.edge.driver&#8221;, &#8220;path of driver&#8221;); WebDriver driver = new EdgeDriver();



<div class="goto-wrapper">

 <a href="https://testsigma.com/blog/setproperty-in-selenium/" class="goto-link">Setproperty in Selenium</a>
 
</div> 



Maximize the Browser



Selenium does not launch the browser in maximize mode, so we need to call maximize() Selenium method to maximize the browser so that test scripts can execute without any errors.



So below code snippet would help to open the browser in Maximize mode.



driver.manage().window().maximize();



3. Navigate to URL



Once the browser opens in maximize mode, we must navigate to the required website. This can achieve by using the get() Selenium method. It accepts a string as a parameter, usually a URL of the application under test, and returns void.&nbsp;



driver.get(&#8220;URL of the application/Website&#8221;);



4. Synchronization using Implicit wait



Synchronization plays a very vital role in test automation. We&#8217;ve seen instances where applications take longer to load, and our test script fails. To handle this dynamic, Selenium introduces <a href="https://testsigma.com/blog/selenium-wait-for-page-to-load/#How_to_Apply_Waits_in_Selenium_for_Page_Load" target="_blank" rel="noreferrer noopener">implicit waiting</a>.



With Implicit wait, we specify a maximum time we would want to wait for an element to be present. In the below snippets, it will wait a maximum of 30 seconds for each element.



driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);



5. Identify the web element by using locating technique of Selenium.



There are different ways by which users can identify the elements of an application.



<ul class="wp-block-list"><li>ID</li><li>className</li><li>Name</li><li>XPath</li><li>tagName</li><li>CssSelector</li><li>linkText</li><li>partialLinkText</li></ul>



To learn more about Xpath in detail, please refer to the link: <a href="https://testsigma.com/blog/xpath-in-selenium/" target="_blank" rel="noreferrer noopener">Xpath selector</a>



6. Verification and Validation



Assertions are used to compare your actual and expected result. If your actual value and expected match, the test case passes. If not, then the test case fails.&nbsp;



Assert.assertEquals(expectedValue, actualValue);



Code Implementation: 



We will automate login functionality for the Testsigma application.



<div class="wp-block-image"><figure class="aligncenter is-resized"><img loading="lazy" decoding="async" src="https://s3.us-east-1.amazonaws.com/blog-assets-production.testsigma.com/blogs/wp-content/uploads/migrated_images/BaldgaS7Oq1z9QxRo9l-KW7wxfqJO9o_QrLk7xrRdI1pur2pBCBekrtMeYSBInBYx2z1qTDTopJPiOMP9U7wkbcnhvrft18Ixz7SR-cxrZq9dFjPoKeRDAW2o55mTZiE6Z11K-RTxF2LBtspK8I1a7mxyKkhaezHaZZhCZd3Hf-o_ciuh69Q7y9fUmkviMjbise-R63MyQ_1748948255.png" alt="Code Implementation" width="600" height="400"/></figure></div>



Let&#8217;s see the code snippet for login automation.



Code:



import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

import org.testng.Assert;

import org.testng.annotations.Test;

public class Sample {

@Test

public void TestSigmaLogin() {

System.setProperty(“webdriver.chrome.driver”, “path of driver”);

WebDriver driver = new ChromeDriver(); // instantiate the browser

driver.manage().window().maximize(); // maximize the browser

driver.get(“https://app.testsigma.com/ui”); // opening the application

driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

driver.findElement(By.id(“loginUsername”)).sendKeys(“xxxxxx@abc.com”); driver.findElement(By.name(“password”)).sendKeys(“xxxxxxx”); 

driver.findElement(By.xpath(“//button[text()=’SIGN IN’]”)).click();

String actualURL = “https://app.testsigma.com/home”;

String expectedURL = driver.getCurrentUrl(); // It will fetch the current URL

Assert.assertEquals(expectedURL, actualURL); // It will verify both the URL are equal 

driver.close(); // It will close the current browser.

}

}

6 Key Steps to Creating A Quality Assurance Plan

Once Unit testing is over and you integrate separate modules to form a complete system, Integration testing comes into the picture. It follows certain specifications to examine the interaction and behavior of different modules as they come together to build a system. 



As such, Integration testing follows two approaches—Top-down and Bottom-up—that offer an organized way of building a programming structure, all the while continuing the testing processes. And this is the exact topic of this article. We will talk about the difference between Top-down and Bottom-up Integration testing for you to understand both approaches in detail.



However, you must have a thorough knowledge of Integration testing and its requirements before you jump to understanding its different approaches. So, here we begin.



<div id="toc_container" class="no_bullets">Table Of Contents<ul class="toc_list"><li><a href="#What_is_Integration_Testing">1 What is Integration Testing?</a><ul><li><a href="#What_are_Different_Types_of_Integration_Testing">1.1 What are Different Types of Integration Testing?</a></li></ul></li><li><a href="#What_is_Top-Down_Integration_Testing">2 What is Top-Down Integration Testing?</a></li><li><a href="#What_is_Bottom-Up_Integration_Testing">3 What is Bottom-Up Integration Testing?</a></li><li><a href="#Difference_Between_Top_Down_and_Bottom_Up_Integration_Testing">4 Difference Between Top Down and Bottom Up Integration Testing</a></li><li><a href="#Key_Takeaways">5 Key Takeaways</a></li><li><a href="#Frequently_Asked_Questions">6 Frequently Asked Questions</a><ul><li><a href="#What_is_the_purpose_of_Bottom-up_testing">6.1 What is the purpose of Bottom-up testing?</a></li><li><a href="#What_is_the_purpose_of_Top-down_testing">6.2 What is the purpose of Top-down testing?</a></li></ul></li></ul></div>
<h2 class="wp-block-heading" id="h-what-is-integration-testing">What is <a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">Integration Testing</a>?</h2>



Integration testing comes after <a href="https://testsigma.com/blog/unit-testing/" target="_blank" rel="noreferrer noopener">Unit testing</a> and follows the communication between several software modules after their design, development, and integration. Testers analyze connected components in this methodology to check for compatibility issues. Often, such issues arise between modules due to data transfer and software-hardware incompatibility.



There are several automation tools available to help you perform Integration testing. Some of the popular tools, such as Selenium, <a href="https://docs.pytest.org/en/7.2.x/contents.html" target="_blank" rel="noreferrer noopener nofollow">Pytest</a>, Testsigma, and <a href="https://testsigma.com/blog/comparison-between-testsigma-and-protractor-alternatives/" target="_blank" rel="noreferrer noopener">Protractor</a>, are all open source and offer several in-house options and <a href="https://testsigma.com/guides/use-case-testing/" target="_blank" rel="noreferrer noopener">use cases for testing</a> purposes.



Integration testing is conducted iteratively for the module group (making up the system) to find the errors. It is an <a href="https://www.planview.com/resources/guide/agile-methodologies-a-beginners-guide/benefits-of-agile-development/" target="_blank" rel="noreferrer noopener nofollow">agile methodology</a> that follows the sprint cycle technique.



<h3 class="wp-block-heading" id="h-what-are-different-types-of-integration-testing">What are Different Types of Integration Testing?</h3>



As already mentioned, there are two approaches to Integration testing. But those are not the only two types. Integration testing has five types in total that testers can employ to perform as per their need:



1. <a href="https://testsigma.com/blog/big-bang-integration-testing/" target="_blank" rel="noreferrer noopener">Big Bang Approach</a>



Under this technique, either all or major modules are integrated for testing. It is only done after all the components are up and running.



2. <a href="https://testsigma.com/blog/incremental-testing/" target="_blank" rel="noreferrer noopener">Incremental Integration </a>



Incremental testing is when a minimum of two (sometimes more) logically related modules are connected for testing, and the same process continues as more modules add to the system.



3. Top-Down Testing



Top-down testing follows a sequential path of dealing with the top modules before moving on to later or sub-modules.



4. <a href="https://testsigma.com/blog/bottom-up-integration-testing/" target="_blank" rel="noreferrer noopener">Bottom-Up Testing</a>



The bottom-up approach is simply the opposite of Top-down testing.



5. Hybrid/Mixed 



As the name suggests, hybrid or mixed Integration testing combines Top-down and Bottom-up to achieve the advantages of both types.



Although all these types have their use cases and advantages, this blog focuses on Top-down and Bottom-up approaches and the differences between them.



Point to Note: Top-down and Bottom-up come under the Incremental Integration testing approach.



<h2 class="wp-block-heading" id="h-what-is-top-down-integration-testing">What is Top-Down Integration Testing?</h2>



Top-down incremental Integration testing builds the program structure by moving from the top module to the lower modules. The process follows a certain downward hierarchy where the lower-level (sub-modules) modules are integrated into the top-level module (main module) using either a depth-first or breadth-first method. The primary advantage of this technique is to verify the control transfer and ease of integration as early as possible.



Almost all the Top-down models rely on Stubs (also called dummy programs) to run the testing. These stubs simulate the functioning of sub-modules.



<h2 class="wp-block-heading" id="h-what-is-bottom-up-integration-testing">What is <a href="https://testsigma.com/blog/bottom-up-integration-testing/" target="_blank" rel="noreferrer noopener">Bottom-Up Integration Testing</a>?</h2>



By the name of it, we are sure you know what Bottom-up Integration testing is and how it functions. But for more clarity, here&#8217;s the definition: Bottom-up Integration takes into account sub-modules and moves upward in the integration process. It eliminates the need for stubs, as lower-level modules are already available for integration before moving on to using the top module. It decreases the amount of overhead present in the Top-down approach.



However, there could be a few instances where all modules are still in production and require a dummy program. In such cases, drivers are used in Bottom-up Integration testing as opposed to stubs used in Top-down Integration testing. Drivers act as &#8216;calling programs&#8217; as opposed to stubs that act as &#8216;called programs.



<h2 class="wp-block-heading" id="h-difference-between-top-down-and-bottom-up-integration-testing">Difference Between Top Down and Bottom Up Integration Testing</h2>



Integration testing can be done in two ways: Top-down and Bottom-up. The fundamental difference between these two approaches is the direction of testing.&nbsp;



In Top-down testing, the testing process starts from the top module and moves downwards towards the sub-modules. The main focus is testing the top module before integrating it with the sub-modules.&nbsp;



In Bottom-up testing, the testing process is initiated by combining the sub-modules and then moving upwards to the top module.



The difference between Top-down and Bottom-up Integration testing is that the former moves downward, and the latter moves upward. Top-down focuses on designing and testing the top module before merging it with sub-modules. Bottom-up, on the other hand, combines the sub-modules to test them and moves upward thereafter.

<h2 class="wp-block-heading" id="h-key-takeaways">Key Takeaways</h2>



At its foundation, Integration testing is the second level of testing right after Unit testing. All the system modules that are designed, developed, and tested during the Unit testing stage go through integration and further examination to check for compatibility issues. While Integration testing has multiple approaches that you can adopt as per your testing needs, two of the popular ones are Top-down and Bottom-up.



Both types have their advantages and disadvantages to help you decide which approach will best serve your needs. And if you are on the lookout for <a href="https://testsigma.com" target="_blank" rel="noreferrer noopener">automation tools</a> that guide your QA team to start and continue <a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">Integration testing</a> based on any one of these two types, we recommend Testsigma and Selenium, as they both offer multiple options in terms of testing. You can choose the former if your team wishes to skip the coding part and move directly on to testing the application.



<h2 class="wp-block-heading" id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h3 class="wp-block-heading" id="h-what-is-the-purpose-of-bottom-up-testing">What is the purpose of Bottom-up testing?</h3>



The purpose of Bottom-up Integration testing is to uncover crucial issues like input or output data usage, which are usually performed by sub-modules early in the testing stage. In short, it focuses on the analysis of specific characteristics and micro attributes of lower modules as per user requirements.



<h3 class="wp-block-heading" id="h-what-is-the-purpose-of-top-down-testing">What is the purpose of Top-down testing?</h3>



The purpose of Top-down integration testing is to view all the components from the top and move downward in a manner to check the system&#8217;s functioning before starting to build the sub-modules. It will help you to catch errors even before you start working on every module of your application system.

<h2 class="wp-block-heading" id="h-what-is-automated-accessibility-testing">What is Automated Accessibility Testing?</h2>



Automated accessibility testing is a process of using software to test for accessibility issues in websites and web applications. This process ensures your app’s content and services are usable by people with disabilities of various types (vision, hearing, etc.). This <a href="https://testsigma.com/blog/the-different-software-testing-types-explained/" target="_blank" rel="noreferrer noopener">type of testing</a> can be used to find and fix issues related to web accessibility, such as missing alt text, improper use of color contrast, and more. 



For instance, overcoming the challenges that a person with vision impairment would encounter when attempting to use any app because the person would be unable to view visuals is what accessibility concerns are about. Keep in mind that automated accessibility testing verifies specific application features to ensure that it is usable by everyone.



While automated accessibility testing is a great tool for finding and fixing accessibility issues, it is important to note that it cannot catch everything. For example, automated testing cannot test for issues related to how well a person can use a website or web application. For this reason, it is also important to manually test websites and web applications to ensure they are accessible to everyone.

<h2 class="wp-block-heading" id="h-can-accessibility-testing-be-automated-with-tools">Can Accessibility Testing be Automated with Tools?</h2>



There is no simple answer to the question of whether web accessibility testing can be automated. While there are some automated tools available, they are not always reliable, and they often require a human touch to be effective.



That said, there are some ways to automate web accessibility testing to some extent. For example, you can use a tool to scan your site for potential accessibility issues and then have a human test those issues to confirm whether they are actually problems. You can also use a tool to generate a report of accessibility issues, which can then be reviewed manually.



Ultimately, the decision of whether to automate web accessibility testing will come down to a cost-benefit analysis. Automated tools can save time and money, but they are not always 100% accurate. So the combination of both automated and <a href="https://testsigma.com/guides/manual-testing/" target="_blank" rel="noreferrer noopener">manual testing</a> is ultimately the most effective method for accessibility testing.

<h2 class="wp-block-heading" id="h-why-automated-accessibility-testing-is-important">Why Automated Accessibility Testing is Important?</h2>



More people are now using digital tools due to the expanding significance of digital technology and applications. However, 70% of websites worldwide are not user-friendly for those with disabilities. Global governments are currently working to make web content accessible to people with impairments as part of the Web Content Accessibility Guidelines (<a href="https://www.wcag.com/" target="_blank" rel="noreferrer noopener">WCAG</a>) 2.0.



Government regulations also mandate that software products be usable by people with impairments. So, as an organization, you should consider these users’ needs as well as those of older adults, children, left-handed users, anti-English speakers, and many others. 



In addition, inaccessible websites cause significant reputational damage to the brand, which is why it&#8217;s crucial to routinely check your site for accessibility blockers using tools.

<h3 class="wp-block-heading" id="h-create-automated-regression-tests-for-accessibility">Create Automated Regression Tests For Accessibility</h3>



As a web developer/owner, it&#8217;s important to ensure that the site is accessible to everyone. One way to do this is to create automated <a href="https://testsigma.com/regression-testing" target="_blank" rel="noreferrer noopener">regression tests</a> that check for accessibility issues.



There are a few different ways to do this, but one tool you can use is the axe-core library. This library provides a set of rules that can be used to automatically test for accessibility issues.



To use the axe-core library, you first need to install it. You can do this by using the following command:



<pre class="wp-block-code"><code>npm install axe-core</code></pre>



After installing axe-core, include the JavaScript file in each of your iframes in your fixtures or test systems to test your site for accessibility issues.



<pre class="wp-block-code"><code>axe
.run()
.then(results => {
if (results.violations.length) {
throw new Error('Accessibility issues found');
}
})
.catch(err => {
console.error('Something bad happened:', err.message);
});</code></pre>



It is possible to create automated accessibility regression testing using the method mentioned above. Additionally, you can completely get rid of most manual testing during the development phase.



<h3 class="wp-block-heading" id="h-use-the-right-test-automation-platform">Use the Right Test Automation Platform</h3>



Traditionally, this testing has been done manually. However, with the rise of test automation, it is now possible to do automated accessibility testing. This can save a lot of time and effort.



There are a number of different tools and platforms available for automated accessibility testing. However, not all of them are equal and have apt features.



<h2 class="wp-block-heading" id="conclusion">Conclusion</h2>



Automated accessibility testing has become an essential aspect of web development. With the growing demand for inclusive and accessible websites, it&#8217;s crucial to ensure that everyone can access and interact with your site regardless of their abilities.

<h2 id="testing-vs-debugging-overview">Testing Vs Debugging &#8211; Overview</h2>


<h3 id="what-is-testing">What is Testing?</h3>


Testing is a process that helps you discover possible issues before the application moves to production (i.e., the application goes live). A developer or a tester does the Testing process through any method &#8211;Automation or Manual. 


Testing involves evaluating a system’s components to determine whether it satisfies the specified requirements. It is a process of ensuring that the application software meets the business requirement.


Testing involves the execution of each test case, which covers all the <a href="https://www.techtarget.com/searchsoftwarequality/definition/use-case" target="_blank" rel="noreferrer noopener">use cases</a> with positive and negative scenarios.


<h3 id="what-is-debugging">What is Debugging?</h3>


Debugging is determining the cause of bugs and errors, and then fixing them. Debugging is a manual process. There are helping tools to debug, which will narrow down the process to an extent.


Various methods of debugging code include:


<ul>
<li>Using breakpoints to halt execution at fixed points in the program, like analyzing variables and their values.</li>
<li>Tracking program flow.</li>
<li>Examining memory contents and simulating possible inputs to detect strange behavior.</li>
</ul>

2. Construct Test Suites:


<ul>
<li>Arrange Test Cases: Group related test cases into test suites for better execution.</li>
<li>Set Priorities: Assign priorities to test cases to ensure critical features are tested first.</li>
</ul>


3. Execute Tests:


<ul>
<li>Cloud Execution: Run tests on different cloud platforms and devices.</li>
<li>Parallel Execution: Test multiple test cases at the same time to expedite the process.</li>
<li>Scheduled Execution: Automate the execution of tests at specific times or intervals.</li>
</ul>


4. Debug Test Failures:


<ul>
<li>Detailed Reports: Look into the results of the test and identify failed test cases.</li>
<li>Screenshots and Logs: Review screenshots and logs to identify the exact point of failure.</li>
</ul>
