<h2 id="h-how-does-a-sandbox-work"><span id="How_Does_a_Sandbox_Work"><strong>How Does a Sandbox Work?</strong></span></h2>



<p>So far we discussed what a sandbox is, what is the purpose of using it, and the different roles the sandbox plays in different scenarios. Now we will see how exactly this sandbox works.</p>



<h3 id="h-isolation"><span id="Isolation">Isolation</span></h3>



<p>Firstly, the sandbox isolates the environment by creating a separate operating system and other related processes which are totally in different networks and storage.</p>



<h3 id="h-virtualization"><span id="Virtualization">Virtualization</span></h3>



<p>Sometimes, even though a new environment is created using a different OS, it is easier to store and maintain the experimental environment such as a sandbox in a virtual infrastructure such as a virtual machine. So, it is recommended to create a sandbox environment in a virtual environment and use technologies such as containerization in practice.</p>



<h3 id="h-access-restrictions"><span id="Access_Restrictions">Access Restrictions</span></h3>



<p>Once the sandbox environment is created, certain configurations are done to prevent access of any files to and fro the environment. For example, if you want to access a db file from the dev environment from your sandbox environment, it is blocked.</p>



<h3 id="h-monitoring"><span id="Monitoring">Monitoring</span></h3>



<p>Once the environment is used, the environment is closely monitored. A system call is a request made by the application to the operating system for performing various tasks, such as file operations, network communication, or memory access. By intercepting and analyzing these system calls, the sandbox can enforce restrictions and prevent unauthorized actions.</p>



<h3 id="h-controlled-termination-of-sandbox"><span id="Controlled_termination_of_sandbox">Controlled termination of sandbox</span></h3>



<p>If the sandboxed application behaves unexpectedly or poses a threat, the sandbox can be terminated safely, preventing any negative impact on the host system.</p>



<h2 id="h-how-do-you-set-up-a-sandbox-environment"><span id="How_Do_You_Set_Up_a_Sandbox_Environment"><strong>How Do You Set Up a Sandbox Environment?</strong></span></h2>



<p>Setting up sandbox may vary depending on needs and technology you’re working on. The steps are as follows:</p>



<p>Firstly, Choose your technology stack. Here you will understand which type of sandbox environment you want to create. For example, VMs, containers,s or some software specific to your use case. Choosing this depends on how you want to deploy your application like in the form of containers or so. Read more <a href="https://blog.hubspot.com/website/sandbox-environment" target="_blank" rel="noreferrer noopener">here</a>.</p>



<p>Next, you install the software like the sandbox applications such as docker, virtual box, and some other apps we discussed in the previous section. Once the sandbox environment is set, create the resources and configure some settings on it as a part of access control.</p>



<h2 id="sandbox-applications"><span id="Sandbox_Applications"><strong>Sandbox Applications</strong></span></h2>



<p id="h-some-of-the-applications-that-make-use-of-sandbox-environment-are-as-follows">Some of the applications that make use of Sandbox environment are as follows:</p>



<h3 id="h-docker"><span id="Docker"><strong>Docker</strong></span></h3>

This tool is specifically used to run containerized applications. It can be run on all kinds of operating systems: Windows, Linux and MacOS.</p>



<h3 id="h-sandboxie"><span id="Sandboxie"><strong>Sandboxie</strong></span></h3>



<p>This is one of the most popular sandbox environment tool which enables you to work on windows OS only. It enables safe browsing feature which allows you to run a browser in sandbox environment which in turn provides security to your system. It also provides resource access control.</p>



<p><strong>Read about <a href="https://testsigma.com/blog/browser-sandbox/" target="_blank" rel="noreferrer noopener">Browser Sandox</a>.</strong></p>



<h3 id="h-firejail"><span id="Firejail"><strong>Firejail</strong></span></h3>



<p>Unlike Sandboxie which is a windows operating system based sandboxing application, Firejail is a linux based sandboxing system. We use servers to generally deploy our applications consisting of various environments such as development, staging, production and many more. When you have to run an experimentation on your application among such critical systems, it is risky and not recommended. Firejail provides the leverage of an entire environment free from any critical systems. Linux is a developer-friendly operating system and this tool is just like a cherry on top!</p>

<h2 id="h-what-is-root-cause-analysis"><span id="What_is_Root_Cause_Analysis">What is Root Cause Analysis?</span></h2>



<p>Root Cause Analysis (RCA) in software testing is a systematic approach used to identify and address the underlying reasons behind software defects. By addressing the underlying causes, RCA helps in improving software quality by enhancing development processes, communication, and collaboration.</p>



<p>RCA involves a structured investigation process that examines various aspects of the software development and testing lifecycle, including requirements, design, coding, testing, and deployment.</p>



<h2 id="h-why-to-perform-root-cause-analysis"><span id="Why_To_Perform_Root_Cause_Analysis">Why To Perform Root Cause Analysis?</span></h2>



<p>Here are some of the key features of root cause analysis in software testing that make it important:</p>



<ul><li>It helps in <strong>cost reduction</strong> associated with defect correction. By pinpointing the accurate reason for errors, RCA helps resolve problems before the software reaches the production stage, where defect identification and mitigation is five times more expensive than the design stage.</li><li>With an error-free product and an efficient RCA process in place, you can identify, solve, and deliver software at an <strong>accelerated speed</strong> to gain a competitive advantage in the market.</li><li>RCA enables companies to find the source of defects to <strong>promote a seamless problem-solving approach</strong> and remove the issue from its root, ensuring better software quality.</li><li>Better quality software is sure to add to the existing customer experience and improve upon it. Clearly, RCA contributes to <strong>enhancing customer satisfaction</strong>.</li></ul>



<h2 id="h-examples-of-root-cause-analysis"><span id="Examples_of_Root_Cause_Analysis">Examples of Root Cause Analysis</span></h2>



<p>Let&#8217;s explore an example where RCA proves invaluable for a high-traffic e-commerce website grappling with sluggish performance during peak periods.</p>



<p><strong>Issue:</strong> The e-commerce website experiences sluggish performance during peak traffic, causing user frustration and potential revenue loss.</p>



<p><strong>RCA Process:</strong></p>



<p>To address this challenge, the testing team initiates the RCA process by collecting performance metrics, server logs, and user feedback. Their comprehensive analysis reveals a critical insight: <strong>the website&#8217;s response time significantly increases when users attempt to add items to their cart.</strong> Further investigation uncovers that the cart update process triggers numerous database queries per item, leading to a database bottleneck that hampers overall performance. With this revelation, the development team takes swift action. They optimize database queries, introduce caching mechanisms, and implement load-balancing strategies for efficient traffic distribution. To prevent future occurrences, performance testing becomes an integral part of the development lifecycle, identifying and rectifying potential bottlenecks at an early stage.</p>



<p>Let’s take another instance where RCA uncovers the intricacies of the problem and offers solutions for consistent, reliable results.</p>



<p><strong>Issue:</strong> A financial software application generates inconsistent financial reports, causing confusion and eroding user trust.</p>



<p><strong>RCA Process:</strong></p>



<p>In this scenario, the testing team embarks on an RCA journey to address data inconsistencies. They begin by conducting meticulous data validation tests, comparing outputs against expected results. Discrepancies emerge, particularly when the application handles extensive data involving complex calculations. <strong>The root cause analysis reveals that certain data inputs contain non-numeric characters that disrupt essential calculations.</strong> Moreover, existing error-handling mechanisms prove inadequate. The development team responds swiftly, enhancing the software&#8217;s defenses with robust input validation mechanisms and bolstering error-handling procedures to ensure precise calculations and consistent outcomes. To safeguard data integrity, automated data validation checks are introduced, and comprehensive data integrity tests become routine during each <a href="https://en.wikipedia.org/wiki/Software_release_life_cycle" target="_blank" rel="noreferrer noopener">release cycle</a>.</p>



<h2 id="h-goals"><span id="Goals">Goals</span></h2>



<p>Root cause analysis in testing has three goals aimed at identifying, mitigating, and preventing issues in the system:</p>



<ul><li>Identify the cause of the problem, i.e., discover the root of the cause.</li><li>Understand the root cause and analyze how to resolve the problem.</li><li>Put the learnings of the analysis into practice to fix the issue and prevent future system breakdowns.</li></ul>



<h2 id="h-rca-in-test-automation"><span id="RCA_in_Test_Automation">RCA in Test Automation</span></h2>



<p><a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">Test automation</a> plays a pivotal role in enabling effective Root Cause Analysis (RCA) by providing consistent, repeatable, and comprehensive testing processes. In a complex software environment, defects can originate from various sources, such as code changes, integration issues, or configuration discrepancies.

<h2 id="h-what-is-test-analysis"><span id="What_is_Test_Analysis">What is Test Analysis?</span></h2>



<p>Test analysis inspects and analyzes the <a href="https://testsigma.com/blog/test-artifacts/" target="_blank" rel="noreferrer noopener">test artifacts </a>to create test conditions or cases. Test analysis aims to collect requirements and create test objectives to establish test conditions. As a result, it&#8217;s also known as Test Basis.</p>



<p>Test analysis is the first step in the test design process. It is essential to perform test analysis carefully and thoroughly to ensure the test cases are complete and adequate.</p>



<h2 id="h-what-is-the-purpose-of-the-test-analysis"><span id="What_is_the_purpose_of_the_test_analysis">What is the purpose of the test analysis?</span></h2>



<p>Test analysis aims to identify any defects or weaknesses in the software and recommend further testing or improvement. It is an essential part of the software testing process and helps ensure the software is tested.</p>



<p>Here are some specific purposes:</p>



<ul><li>To identify defects in the software.</li><li>To determine the severity of defects.</li><li>To focus on defects for fixing.</li><li>To make recommendations for further testing.</li><li>To improve the testing process.</li><li>To guarantee that the software meets its needs.</li><li>To reduce the risk of defects being released to production.</li></ul>



<p>The test analysis results can improve the<a href="https://www.simplilearn.com/tutorials/devops-tutorial/fundamentals-of-software-testing" target="_blank" rel="noreferrer noopener"> testing process</a>, such as identifying areas where the testing was ineffective or if new test cases need to be created.</p>



<h2 id="why-is-test-analysis-critical"><span id="Why_is_test_analysis_critical">Why is test analysis critical?</span></h2>



<p>Test analysis is essential because it helps ensure that the correct tests are executed, and the results are accurately interpreted. By carefully analyzing the test results, testers can identify potential defects in the software and recommend corrective actions.</p>



<p>Test analysis is also essential for improving the overall quality of the testing process. By understanding the strengths and weaknesses of the test cases, testers can make necessary adjustments. This will improve the efficiency and effectiveness of the testing process.</p>



<h2 id="what-are-the-criteria-for-test-analysis"><span id="What_are_the_criteria_for_test_analysis">What are the criteria for test analysis?</span></h2>



<p>The criteria for test analysis vary depending on the specific project and the testing methodology used. However, some standard criteria include:</p>



<ul><li><strong>Completeness</strong></li></ul>



<p>Do the test cases and test suites cover all required functionality and performance requirements?</p>



<ul><li><strong>Correctness</strong></li></ul>



<p>Are the test cases well-designed and accurate?</p>



<ul><li><strong>Effectiveness</strong></li></ul>



<p>Are the test cases effective in identifying defects?</p>



<ul><li><strong>Efficiency</strong></li></ul>



<p>Can the test cases be executed quickly and efficiently?</p>



<ul><li><strong>Maintainability</strong></li></ul>



<p>Can the test cases be easily updated and maintained?</p>



<h2 id="issues-encountered-when-test-analysis-is-done-during-black-box-testing"><span id="Issues_encountered_when_Test_Analysis_is_done_during_Black_Box_Testing">Issues encountered when Test Analysis is done during Black Box Testing</span></h2>



<p>Black box testing is a type of software testing performed without any knowledge of the internal structure of the software.&nbsp;</p>



<p>This can make test analysis challenging. Because testers need to rely on their understanding of the software requirements and their own experience to design and execute effective test cases.</p>



<p><strong><em>Some of the specific issues of test analysis in black box testing include:</em></strong></p>



<ul><li><strong>Identifying all possible inputs</strong>: It can be difficult to identify all possible inputs to a black box system, especially for complex systems. This can lead to incomplete test coverage.</li><li><strong>Designing test cases for internal states:</strong> It can be challenging to design them for internal states of a black box system, as testers cannot directly observe them. This can lead to ineffective test cases.</li><li><strong>Interpreting test results:</strong> It can be challenging to interpret the results of black box tests. This is because the testers cannot directly observe the internal behavior of the system. This can make it difficult to identify the root cause of test failures.</li></ul>



<h2 id="an-approach-to-test-analysis-based-on-test-categories"><span id="An_Approach_to_Test_Analysis_Based_on_Test_Categories">An Approach to Test Analysis Based on Test Categories</span></h2>



<p>Test analysis based on test categories is a systematic approach that divides test cases into categories based on their purpose.&nbsp;</p>



<p>This can help ensure that all aspects of the software are tested, and the test cases are effective.</p>



<p><strong><em>The following are some standard test categories:</em></strong></p>



<p><strong>Functional testing</strong></p>



<p>Tests the functionality of the software to ensure that it meets the requirements. This includes testing the software&#8217;s features,&nbsp; user interface, and user experience.</p>



<p><strong>Performance testing</strong></p>



<p>Tests the performance of the software to ensure that it can handle the expected load and respond within acceptable timeframes. This includes testing the scalability of the software, as well as its throughput and response time.</p>



<p><strong>Security testing</strong></p>



<p>Tests the security of the software to identify and mitigate any vulnerabilities. This includes testing the software for common security weaknesses, such as SQL injection and cross-site scripting.</p>



<p><strong>Usability testing</strong></p>



<p>Tests the usability of the software to ensure that it is easy to learn and use. This includes testing the software for navigability, clarity, and consistency.</p>



<p><strong>Example of Test Analysis Based on Test Categories</strong></p>



<p>Consider a simple web application that allows users to log in, register, and view a list of products. The test cases for this application could be categorized as follows:</p>



<ul><li><strong>Functional testing:</strong><ul><li>Login test cases</li><li>Registration test cases</li><li>Product viewing test cases</li></ul></li><li><strong>Performance testing:</strong><ul><li>Login performance test cases</li><li>Registration performance test cases</li><li>Product viewing performance test cases</li></ul></li><li><strong>Security testing:</strong><ul><li>Login security test cases</li><li>Registration security test cases</li><li>Product viewing security test cases</li></ul></li><li><strong>Usability testing:</strong><ul><li>Login usability test cases</li><li>Registration usability test cases</li><li>Product viewing usability test cases</li></ul></li></ul>



<p>Once the test cases have been categorized, the testers can analyze each category to ensure that the test cases are complete, correct, effective, efficient, and maintainable.</p>



<h2 id="h-how-to-do-test-analysis-steps"><span id="How_to_do_Test_Analysis_Steps">How to do Test Analysis: Steps</span></h2>



<p>Testing can be a serious business, but that doesn&#8217;t mean we can&#8217;t have a little fun with it. So, let&#8217;s look at the steps involved in this.</p>



<h3 id="h-review-test-basis"><span id="Review_test_basis">Review test basis:</span></h3>



<p id="h-this-is-the-first-step-in-test-analysis-and-it-involves-reviewing-the-documentation-that-forms-the-basis-for-the-test-cases-this-documentation-can-include-the-requirements-design-specifications-risk-analysis-and-any-other-relevant-information">This is the first step in test analysis, and it involves reviewing the documentation that forms the basis for the test cases. This documentation can include the requirements, design specifications, risk analysis, and any other relevant information.&nbsp;</p>



<h3 id="h-identify-test-conditions"><span id="Identify_test_conditions">Identify test conditions:</span></h3>



<p>Once the test basis has been reviewed, the next step is identifying the test conditions. A test condition is a specific set of circumstances that must be tested. For example, a test condition for a login feature might be &#8220;a user is able to login when they enter a valid username and password.&#8221;&nbsp;</p>



<h3 id="h-designing-test-cases"><span id="Designing_test_cases">Designing test cases:</span></h3>



<p>The next step is to design the test cases. A test case is a document that describes a specific test condition and the steps that need to be taken to execute the test. The test cases should be designed to cover all of the identified test conditions, and they should be written clearly and concisely.</p>



<h3 id="h-expected-and-unexpected-inputs"><span id="Expected_and_unexpected_inputs">Expected and unexpected inputs:</span></h3>



<p>The final step is to identify the expected and unexpected inputs for each test case. The expected input is the input that is expected to produce the desired output. The unexpected input is an input that is not expected to produce the desired output. The goal of this step is to ensure that the test cases are comprehensive and that they cover all of the possible scenarios.</p>



<p>Here are some additional things to keep in mind:</p>



<ul><li>Test analysis is an iterative process.&nbsp;</li><li>The <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test cases</a> may need to be revised and updated as the software is developed and tested.</li><li>It should be performed by a skilled test analyst who understands the software and the testing process well.</li><li>The test analysis results can improve the testing process and ensure the software is tested thoroughly and effectively.</li></ul>

<p>A <a href="https://testsigma.com/blog/test-plan/" target="_blank" rel="noreferrer noopener">test plan</a> provides a broad strategy and approach for testing a software system or application, including objectives, scope, resources, and timelines. The test plan will include details such as the type and number of tests that need to be conducted, the purpose of each test, the required tools, and how test results will be analyzed and reported. It is regularly updated throughout the testing process to reflect any discoveries or changes in strategy.</p>

Test Plan vs. Test Case Top Key Differences

Test Plan vs Test Case | Top Key Differences


<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 class="title-with-description ">

</div>
<a href="https://testsigma.com/tools/responsive-design-testing-tools/" target="_blank" class="cta-btn-v1" rel="noopener">Check Responsiveness</a>
</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>



<p>Test your mobile apps and websites on real devices on the cloud &#8211; <a href="https://testsigma.com/online-android-emulator">Try for Free</a></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>With Testsigma, you can achieve maximum device coverage and ship apps that are responsive, compatible, and functional on all browser combinations. It allows QA to automate web, mobile, desktop, API, SAP, and Salesforce tests across 3000+ real devices and browsers.</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>



<p>Here are some features that make Testsigma the ideal solution for testing teams across industries:</p>
