Let’s say that you’re an engineer who just built a new car engine. You wouldn’t distribute it to customers without first testing the engine, would you? No, I didn’t think so - that is unless you enjoy lawsuits.

For an engineer selling his defective engine to customers, it’s clearly a matter of safety. Well, obviously, a web or mobile application won’t cause a fatal car accident due to negligence, but it could cause investors to back out of a multi-million dollar deal.

When it comes to building a new application or software solution, developers and quality assurance experts need to test their product before deploying it for distribution.

As professional quality assurance (QA) testers, we’re more than aware of why QA testing is crucial to the application and software development process.

When testing QA for software solutions and applications, we don’t just leverage one tool - we utilize several different types for different purposes. Whether we’re performing functional, unit, integration, smoke, interface, regression, or other testing types, we harness the power of the best automated QA testing tools available on the market.

In this article, we’ll discuss the 10 best automation testing tools for 2021.

1. Selenium

Selenium

Selenium is a well-known open-source web automated testing solution leveraged by QA testers everywhere.

Fully managed and highly scalable, Selenium is designed for larger enterprise-size organizations typically within the banking, insurance, medical, and other security-sensitive industries.

Selenium combines SaaS solution features with the security and performance of in-house/on-premise corporate cloud deployment.

What QA testers like about Selenium, in particular, is that it offers a record and playback feature within its add-on SeleniumIDE. This makes it easy for testers to see the changes made in real-time, thus providing added flexibility and accuracy throughout the testing process.

Selenium is one of the few automated testing solutions in high demand in the market, automating software across multiple operating systems, including Mac, Windows, Linux, and browsers like Google Chrome, Firefox, IE, and headless browsers.

It also helps testers write tests in popular programming languages, such as Java, Python, Groovy, Ruby, PHP, C#, and Perl, which is great for testers that are most familiarized with these languages.

So, if you’re a new up-and-coming QA tester looking to master their craft, then we suggest learning more about Selenium, as it is undoubtedly one of the best automation testing tools on the market.

2. Telerik Test Studio

Telerik Test Studio

Telerik offers automated load, UI, and performance testing across desktop, web, and mobile applications.

Telerik supports HTML5, ASP.NET, JavaScript, MVC, WPF, Silverlight, AJAX, Ruby, and PHP programming languages and integrates with Visual Basic Studio 2010 and 2012.

Like Selenium, Telerik offers a record and playback feature plus a feature that allows testers to schedule tests to automate the process further.

Testers who are highly familiarized with C# and/or VB.NET scripting languages enjoy Telerik because they are the two scripting languages that it supports.

Like how people enjoy speaking their primary language of origin, every QA tester has a preference for programming languages. Whichever programming language a tester enjoys writing in most determines which test automation tools they choose.

So, if any of these supported languages “speak” to you most, then Telerik might just be the best automation testing solution for you.

3. Katalon Studio

Katalon Studio

This all-in-one test automation solution supports web and mobile app development environments and provides hassle-free deployment and fast results.

Katalon Studio’s robust, popular, and stable integration capabilities provide added flexibility and interoperability for API testing - which QA testers love.

Katalon is built on top of Appium and Selenium open-source automated frameworks with a specialized IDE interface for web, mobile, and API testing.

Testers enjoy Katalon’s customizable execution workflows and duel-editor interface, which allows them to overcome several common web UI test automation challenges. Katalon can also be integrated with Slack, JIRA, Kobiton (another tool on our list), qTest, Git, and other software testing automation tools.

Katalon is also a great tool to use for QA testers with minimal experience, so you won’t be overwhelmed with programming jargon. It’s built with hundreds of keywords for creating custom test cases and is highly versatile, running on macOS, Linux, and Windows.

4. LambdaTest

LambdaTest

LambdaTest is by far one of the best automation testing tools for 2021 because of its ability to run automated Selenium scripts on a scalable cloud grid.

This cross-platform web and application automated testing tool also allows testers to perform interactive live testing on 2,000+ real web browser environments. That’s a lot of leverage!

Enabling automated screenshot testing on 25 combinations simultaneously, LambdaTest offers more robust options than most other automated testing solutions.

For Selenium-users, LambdaTest is an excellent automated testing tool to take advantage of since it has a built-in Selenium Grid that allows testers to debug Selenium scripts.

LambdaTest also allows testers to extract Selenium reports using its RESTful API and includes automated test logs, such as command logs, exception logs, network logs, raw Selenium logs, and metadata.

Another critical aspect that QA testing pros love about LamdaTest is that it provides codeless test automation and multiple third-party integration capabilities to help testers fast track the testing and go-to-market launching process.

5. Kobiton

Kobiton

Kobiton is an excellent automation testing tool for mobile and internet of things (IoT) continuous testing. It automated performance, functionality, compatibility, and visual tests with AI-driven scriptless approaches and/or script-based and open-source tooling.

For QA testers who need fast, easy, and hassle-free mobile application testing solutions, then Kobiton may just be the way to go. What’s great about Kobiton is that it allows testers to test the code on real devices directly within their IDE! This is great for testers who enjoy a more hands-on approach to QA testing, resolving test failures with maximum accuracy and efficiency so that they can release the app quicker.

Kobiton also offers seamless CI/CD integrations, AI-assisted remediation for IoT testing, and in-depth session exploration and reporting features.

Developers, testers, and DevOps love harnessing the power of Kobiton for their go-to automated and/or manual testing needs.

6. TestArchitect

TestArchitect

TestArchitect is another codeless test automation tool that utilizes an action-based form of keyword-driven testing for desktop, cross-browser, mobile, API, and computer vision testing platforms.

TestArchitect enables integrations with most of the leading CI/CD/DevOps tools, including Jenkins, TFS, Azure DevOps, and more.

The main aspect of TestArchitect that more-technical testers love so much is that they can support a lot of less-technical testers using this tool to achieve more automation coverage. This means that this solution is ideal for those with less experience, thus allowing software development companies to cover more ground in less time.

So, for testers with minimal experience or QA connoisseurs, TestArchitect is a great tool for testers that value solutions that offer high reusability coupled with less maintenance.

7. Cucumber

Cucumber

For QA testers that focus on driving enhanced end-user experience above all other factors, then Cucumber is the right choice.

This open-source behavioral-driven development (BDD) tool supports Java, Ruby, Groovy, and Scala programming languages executed on Ruby, Selenium, and other supported frameworks.

Cucumber supports only the web environment and is written in simple English called Gherkin. Approximately 20% of QA testers use Cucumber for its philosophy on delivering the best end-user experience possible.

Utilizing Cucumber also empowers team collaboration by integrating with Jira and reports in JSON and HTML formats to monitor team members’ performance.

Regardless of technical knowledge and experience, QA testers of all calibers can leverage Cucumber’s behavior-driven testing solution.

8. Appium

Appium

In recent years, Appium has reached a high level of popularity and is quickly emerging as one of the best open-source mobile automation testing tools on the market.

Based on server architecture, backing native, hybrid and mobile apps, Appium’s philosophy is built on the idea that testing native apps should not require an SDK or recompilation.

The greatest aspect of Appium that testers love most is that it allows them to automate mobile apps from any programming language or test framework. This enables developers to utilize their favorite dev tools, including PHP, Ruby, JavaScript, Python, C#, and so many more.

Driving Android, iOS, and Windows app testing using the WebDriver protocol, Appium delivers high performance, optimized stability, and maximize flexibility for mobile-based testing.
