Mobile Browser Testing:  Comprehensive Guide, Best Practices & Tools


<p>In the early stages of any SDLC, it may not be feasible to run tests on real desktop and mobile devices. This is because the code is still in an immature stage, and many teams may not have the budget to access a real device cloud from the first test.&nbsp;</p>



<p>The solution? Browser emulators.&nbsp;</p>



<p>This article will define browser emulators and discuss their benefits and usability in testing websites within QA funnels.&nbsp;</p>

<h2 id="what-is-a-browser-emulator"><span id="What_is_a_browser_emulator">What is a browser emulator?</span></h2>



<p>A browser emulator is an application or environment that replicates the functions, design, and user-facing behavior of an actual web browser. For example, an online browser emulator can replicate the MacOS on a Windows machine, letting you test apps on Safari without having to get a MacBook.&nbsp;</p>



<p>Emulators are used by analysts, devs, and testers to run applications for usage, testing, and debugging. They don’t need the actual browser, just the emulator.&nbsp;</p>



<p>Testing on a browser emulator is not a replacement for testing on real browsers, devices, and OSes. But it is perfect for testing sites at the early stages of development.&nbsp;</p>



<h2 id="common-features-of-the-browser-emulators"><span id="Common_features_of_the_Browser_Emulators">Common features of the Browser Emulators</span></h2>



<ul><li>Replicates different browsers on different platforms (with some reduced functions).&nbsp;</li><li>Simulates web page rendering with JavaScript, CSS, and DOM manipulation support.&nbsp;</li><li>Automates user actions like clicking, form inputs, moving between pages, and so on.&nbsp;</li><li>Allows adjustments in screen dimensions, device orientation, network conditions, location, etc.&nbsp;</li><li>Emulates browser APIs for geolocation, local storage, session storage, etc.&nbsp;</li><li>Allows for programmatically crawling and scraping web pages with visible browser interaction.&nbsp;</li></ul>



<h2 id="the-role-of-browser-emulators-in-quality-engineering"><span id="The_role_of_browser_emulators_in_Quality_Engineering">The role of browser emulators in Quality Engineering</span></h2>



<p>At the early stages of software development, browser emulators can take on a set of roles that help push code with some testing. Browser emulators can be used for&nbsp;</p>



<ul><li>Cross browser testing</li><li>Functional testing</li><li>Performance testing</li><li>Responsive design testing</li></ul>



<div class="cta-banner-v2">

</div>



<p>However, it is always recommended to run security tests, accessibility tests, regression tests, and all pre-production tests on real devices.&nbsp;</p>



<h2 id="benefits-of-testing-on-browser-emulators"><span id="Benefits_of_testing_on_browser_emulators">Benefits of testing on browser emulators</span></h2>



<h3 id="cost-effective-testing"><span id="Cost-effective_testing">Cost-effective testing</span></h3>



<p>When you test on a web browser emulator, you don’t need immediate access to real browsers, devices, and OS. A single browser emulator can replicate multiple environments, cutting down the need for real device access from the first stage of development.&nbsp;</p>

<h3 id="support-for-responsive-testing"><span id="Support_for_responsive_testing">Support for responsive testing</span></h3>



<p>Emulators are useful for checking how the site renders on browsers load on different device sizes. For example, what would your site look like on Safari mobile vs Safari desktop? What about its functionality when Safari is running on different iPhones? These are questions the browser emulators can answer.&nbsp;</p>



<h3 id="early-stage-debugging"><span id="Early-stage_debugging">Early-stage debugging</span></h3>



<p>Testing on browser emulators can help QA engineers identify JavaScript errors, layout anomalies, and console warnings. It works fairly well for DOM inspection, network monitoring, and performance profiling.&nbsp;</p>



<h3 id="easy-and-quick-scaling"><span id="Easy_and_quick_scaling">Easy and quick scaling</span></h3>



<p>The low cost and high efficiency of emulators make them a great option to scale tests quickly. For example, if you’d like to run a new feature through a preliminary set of tests, a robust browser emulator works perfectly. Set up a series of emulated browsers for the initial round of checks.&nbsp;</p>

<h2 id="drawbacks-of-browser-emulators"><span id="Drawbacks_of_browser_emulators">Drawbacks of browser emulators<gwmw style="display:none;"></span></h2>



<h3 id="gaps-inaccuracy"><span id="Gaps_inaccuracy">Gaps inaccuracy<gwmw style="display:none;"></span></h3>



<p>No browser emulator can replace the real browser. If it could, no one would bother using or upgrading the actual browser.&nbsp;</p>



<p>Often, visual elements and animations do not render on emulators the way they do on real devices. This leads to overlooking UI bugs that tarnish end-user experience.&nbsp;</p>



<p>In particular, emulators are unsuitable for monitoring website behavior for complex scenarios and edge cases. Browser emulators leave too many real-world variables uncertain because they simply cannot replicate them. Instead, you can choose to run your tests on a cloud-based <a href="https://testsigma.com/test-lab" target="_blank" rel="noreferrer noopener">test lab</a> to test your apps and websites on real devices and browsers.<gwmw style="display:none;"></p>



<h3 id="incomplete-hardware-emulation"><span id="Incomplete_hardware_emulation">Incomplete hardware emulation</span></h3>



<p>Online Browser emulators cannot completely recreate hardware behaviors like CPU performance variations, multi-touch gestures, device-specific bugs, and touchscreen sensitivity. It certainly cannot support advanced features like gyroscopes, fingerprint scanners, or accelerometers.&nbsp;</p>



<h3 id="network-discrepancies"><span id="Network_discrepancies">Network discrepancies</span></h3>



<p>Conditions like high or low latency or packet loss are not always accurately simulated by browser emulators. If the emulator in question runs on high-resource developer machines, it may not work properly on lower-end devices.&nbsp;</p>



<h3 id="gaps-in-browser-specific-features"><span id="Gaps_in_browser-specific_features">Gaps in browser-specific features</span></h3>



<p>Most browser emulators cannot support plugins and extensions, leaving gaps in tests. Proprietary APIs and experimental features are also impossible to emulate for most accessible emulators.&nbsp;</p>



<p>This takes away from the accuracy of test results, leaving emulator-tested websites riddled with bugs that users will find.&nbsp;</p>



<h3 id="limitations-in-accessibility-and-security-features"><span id="Limitations_in_accessibility_and_security_features">Limitations in accessibility and security features</span></h3>



<p>Emulators can mimic a few accessibility settings but are reportedly not great at fully replicating screen readers, braille displays, and voice-to-text conversions.&nbsp;</p>



<p>Additionally, emulators are not recommended for security testing as they cannot recreate the browser backend—browser-specific exploits, cookies, and session management. Security tests verify the mechanisms that will safeguard sensitive information, but this cannot be accomplished on a tool that can’t replicate all real-world scenarios, such as cross-origin attacks.&nbsp;</p>



<h3 id="limited-support-for-older-niche-browsers-dependence-on-updates"><span id="Limited_support_for_olderniche_browsers_dependence_on_updates">Limited support for older/niche browsers &amp; dependence on updates</span></h3>



<p>Many emulators cannot accurately recreate older browser version environments. They face similar issues when emulating browsers with unique rendering engines. You may not be able to replicate browsers for niche operating systems or device specifications.&nbsp;</p>



<p>Emulators also have to keep being updated regularly; if they aren’t, they will lag in real-world scenarios. Similarly, truly effective emulators for newer browsers take time to release, and depending on them delays your entire test pipeline.&nbsp;</p>



<h2 id="how-to-use-a-browser-emulator-online"><span id="How_to_use_a_browser_emulator_online">How to use a browser emulator online</span></h2>



<p>Browser emulators do not let users mimic real-world scenarios with 100% accuracy. It is best to choose a test automation platform that supports real device testing for automating browser tests. Testsigma is a codeless GenAI-powered test automation platform that offers a real device cloud for testing on actual devices and not emulators.&nbsp;</p>

<p>No.&nbsp;</p>



<p>Browser emulators can do a great deal to verify a website’s compatibility, functionality, and performance. However, as the previous section on “Drawbacks” reveals, there are too many gaps in production-level accuracy for emulator tests to reflect real-world conditions.&nbsp;</p>



<p>Emulators miss out on hardware-based features, cannot faithfully replicate real-world user activity loads, and don’t support many browser APIs, plugins, or experimental features. They also cannot mimic the strained network connectivity users often have to deal with in their actual lives.&nbsp;</p>



<p>All these factors make browser emulators unsuitable for pre-release testing. Real devices must come into play, and tests must be designed to test the website in practical user scenarios.&nbsp;</p>



<h2 id="instead-of-browser-emulators-test-on-real-devices-on-the-cloud"><span id="Instead_of_browser_emulators_test_on_real_devices_on_the_cloud">Instead of browser emulators, test on real devices on the cloud</span></h2>



<p>It is certainly not possible for every QA team to buy, maintain, and upgrade a vast repository of devices. The financial and human resources required to set up and manage such an in-house device lab would be too much for most businesses.&nbsp;</p>



<p>The solution is to run all software tests on a cloud hosting real desktop and mobile devices—a cloud very much like the one offered by Testsigma. Create, execute, and manage tests entirely on the cloud, and get rid of all your infrastructure overhead.&nbsp;</p>

<h2 id="1qf6e"><span id="Cross_Browser_Testing_Checklist_for_General_Browser_Compatibility"><strong>Cross Browser Testing Checklist for General Browser Compatibility </strong></span></h2>



<p>This <a href="https://testsigma.com/blog/web-app-testing-checklist/" target="_blank" rel="noreferrer noopener">website Testing checklist</a> tests the critical features for the website to work correctly. Some of the most important ones are listed below:</p>



<ul><li>Validate the CSS, HTML and XHTML. This will ensure that all code meets relevant standards and that there are no open tags.</li><li>Validate the SSL certificate. Some SSL certificates are not compatible with all browser versions, so checking this before proceeding is essential. You also need to know who owns the website domain you&#8217;re using.</li><li>Take care of visual elements; validate the fonts, fields, and design.</li><li>To ensure that web pages are displayed correctly on various screens with different size ratios and resolutions, it is crucial to verify that they work effectively on multiple screens. Browsers may apply their default styles to your website by default. Chrome, for example, will add a default margin to your website – a minor but perceptible difference if you pick a darker background color.</li></ul>



<p>To resolve this, you can use some code to reset the defaults, removing the mystery of why some styles differ in different browsers.</p>



<ul><li>It is also essential to verify the DOCTYPE instructions on every webpage. Define the language in which the code is written at the start of your HTML file(s) so that browsers can appropriately read it. This ensures that all browsers will parse the web pages similarly.</li><li>Since <a href="https://blog.hubspot.com/website/api-calls" target="_blank" rel="noreferrer noopener">API calls</a> can differ between browsers, you must be cautious if your application uses APIs. It would be best to ensure that the APIs used are compatible across various browsers to avoid compatibility issues.</li><li>Another essential thing to do is verify the HTML&#8217;s X-UA-Compatibility meta tag. This helps to overturn a user&#8217;s compatibility view setting in Internet Explorer for your website.</li><li>Both points are crucial for ensuring that your website is accessible and secure for all users.</li></ul>

<ul><li>Check that the layout, style, and design are consistent in all browsers used for Cross Browser Compatibility Testing.</li><li>All images present should be in standard resolution.</li><li>Check the correctness of Basic alignment settings on all browsers and operating systems used for Cross Browser Compatibility Testing.</li><li>Make sure all fonts and designs are incorporated correctly and consistent in size, colors, etc., on all browsers used.</li><li>Ensure that everything looks and functions correctly across all different browsers. This includes ensuring that all boxes and forms are aligned perfectly, that colors are uniform, and that headers and footers are consistent.</li><li>Check the site&#8217;s responsiveness on different browsers and ensure that data is aligned correctly.</li><li>Check browser compatibility for any audio or video formats you&#8217;re using.</li><li>Ensure the source code doesn&#8217;t contain typos or other errors.</li><li>Check that the zoom-in and zoom-out functions work correctly.</li><li>Hover over elements with the mouse to ensure they can be selected correctly.</li><li>Check that all drop-down menus show all the available options.</li><li>Test the navigation between web pages to ensure it&#8217;s fast and accurate.</li><li>Check that pop-up appear correctly and consistently on all browsers.</li><li>Make sure that any tables or grids on the website are aligned correctly.</li></ul>



<p>Taking these steps can help ensure that your website looks great and works well no matter what browser someone uses.</p>



<h2 id="24bjb"><span id="Cross_Browser_Testing_Checklist_of_Functional_Compatibility"><strong>Cross Browser Testing</strong> <strong>Checklist of Functional Compatibility:</strong></span></h2>



<p>Use the functional checklist below to ensure that all website functions work as expected in all browsers used for Cross Browser Compatibility Testing:</p>



<ul><li>Verify that all plugins integrated into the website are compatible with all browsers.</li><li>When downloading and uploading, verify that the formats of files (text, images, videos, etc.) are compatible.</li><li>Verify jQuery and AJAX functionalities.</li><li>Ensure that search results are accurate, navigation links work correctly, and an error page appears when the website does not respond.</li><li>Ensure all functions (e.g., saving data, importing and exporting, submission) are working correctly.</li><li>Check that flash is working properly and that any animations function correctly across browsers.</li><li>Ensure device interaction (keyboard, mouse) is uniform across different browsers.</li><li>Ensure script validation across different browsers.</li><li>Test the ability to handle different loads on different browsers.</li></ul>



<h2 id="how-to-decide-which-browsers-to-test-on"><span id="How_to_Decide_Which_Browsers_to_Test_on"><strong>How to Decide Which Browsers to Test on?</strong></span></h2>



<p>Making a decision on which browsers to test boils down primarily to two ideas: your user demographics and your testing capacity.&nbsp;</p>



<p>Here is a simplified breakdown:</p>



<p><strong>1. Who are your users?</strong></p>



<p>Identify the browsers that your website visitors are already using.&nbsp;</p>



<p>You need to identify your target audience: consider the people you want to reach. For a business audience, it is likely that they mostly use Chrome or Firefox. If your target users are iPhone owners, then testing on Safari is essential.</p>



<p><strong>2.</strong> <strong>So how many browsers should you be testing?</strong></p>



<p>Test on the popular browsers first such as Chrome, Safari, Firefox, and Edge— these are among the most popular browsers used by people all over the world.</p>



<p>If you cannot test on all browsers: prioritize those most frequently used by the people you are targeting.</p>



<p>Do not forget about older browsers because some users might still use them. Although in general cases this number is quite small, decide if it is important to test on them based on your audience and available resources.</p>



<p><strong>Here are a few examples:</strong></p>



<p>For a news website with a worldwide audience, consider testing on Chrome, Safari, Firefox, and Edge as these browsers collectively reach a significant user base.</p>



<p>When it comes to a business-oriented application, you may want to consider prioritizing Chrome and Firefox as they are widely recognized for their compatibility with office tasks.</p>



<h2 id="how-to-find-the-right-balance-while-choosing-browsers"><span id="How_to_Find_the_Right_Balance_While_Choosing_Browsers"><strong>How to Find the Right Balance While Choosing Browsers</strong>?</span></h2>



<p>Picking the right combination of browsers, devices, and operating systems to test on is vital to businesses. Hence, finding the right balance depends heavily on the financial resources the business can spare and its specific needs. Finding the right balance of testing minimum combinations is essential to ensure maximum usage and a positive user experience.</p>

Cross Browser Compatibility Testing Checklist: The Do's and Dont's cover

Cross Browser Testing Checklist: The Do’s and Dont’s


<p><span data-offset-key="dhb19-0-0">When you build a web application, it must work well across various OS platforms and browsers. In simple terms, verifying the web application&#8217;s performance and compatibility is necessary. In recent trends,  automation testing is a top-notch framework that automates the effort of manual testing. Selenium is one such tool that fits well in this scenario. In this blog post, let&#8217;s understand how to perform cross browser testing using Selenium WebDriver.</span></p>



<p>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<strong>. </strong></p>



<p>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.</p>

<figure class="wp-block-table"><table><tbody><tr><td><strong>Best practices</strong></td><td><strong>Reasons</strong></td></tr><tr><td>Selecting the right libraries and frameworks</td><td>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.</td></tr><tr><td>Employ relevant JavaScript libraries and task runners</td><td>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.</td></tr><tr><td>Identify and analyze your browser&#8217;s OS configuration</td><td>To effectively perform 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.</td></tr><tr><td>Optimize for Internet Explorer</td><td>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;</td></tr></tbody></table></figure>
