      Test automation increases efficiency, speeds up bug detection, and supports quality assurance. Find the best automated software testing tool to speed up your testing process.

      Automated software testing tools - why do we need them?

      Applications are constantly growing and growing. They have more and more functionalities and offer newer possibilities. Every functionality and every available option should be tested to ensure the release of bug-free and high-quality products. No end user wants to receive an application that doesn't work, especially if they paid for it.

      Rapidly developed applications require fast and accurate testing. Unfortunately, manual tests are not always sufficient. You need to check many test cases usually in a really short time and make sure not to miss any path. In such cases, it is not possible to fully eliminate human errors. Automatic tests are the answer to these needs.

      Automated software testing has many advantages. The most important are repeatability and accuracy. Once a test is programmed, it will always be performed in the same way. Unfortunately, such accuracy and repeatability cannot always be achieved with manual tests. Additionally, automated tests are efficient, you can execute a larger number of tests in less time. Instead of spending time clicking through the program carefully, you can spend it on improving the software or providing greater test coverage for your application. Automated testing also allows you to detect errors much faster than manual testing.

      To help you make the best choice, we prepared a list of the top 10 automated software testing tools that are worth considering.

      Best automated software testing tools


      Selenium is the most popular open-source automated software testing framework for web applications. It supports multiple programming languages including Java, Python, C#, Ruby, and JavaScript, making it highly flexible and accessible to developers. 

      Selenium offers many components that you can use while testing your apps. Among them you can find:

      • Selenium WebDriver - It provides a programming interface to create and execute test cases for web applications across different browsers and platforms. It enables testers to simulate user actions, for example clicking buttons, entering text, and navigating through pages.
      • Selenium IDE - Integrated Development Environment it is a browser extension available for Chrome and Firefox that allows testers to record their interactions with a web application and then replay those interactions to automate testing tasks.
      • Selenium Grid - It allows running tests across multiple machines and browsers in parallel, which reduces test execution time. 

      Selenium is flexible, has many features, and has large community support. What’s more, it is open-source, which makes it free for both individual and commercial use. This is the most popular solution and worth considering when running tests simultaneously on different browsers is needed.


      Appium, like Selenium, is an open-source solution that you can use for free. Its initial goal was to help in mobile apps testing, but now… This tool allows you to test applications of various types: mobile (native and hybrid), web, desktop, and even those intended for TV!

      Just like Selenium, Appium supports many programming languages so testers can use their preferred languages. It also uses WebDriver to enable testing on different platforms. This allows Appium to control mobile devices and emulate user actions without modifying the app.

      You don’t have to modify your app code to run tests and thanks to that your tests are more realistic. What’s more, it’s pretty easy to integrate Appium with your mobile application. One more thing - you can use one code base for both platforms (Android and iOS). With Appium you can also run tests on real devices and simulators.
      This is one of the best solutions for mobile apps.


      Cypress is also an open-source end-to-end testing framework. It is used to test modern web applications. It is known for its fast execution, simple setup, and powerful features tailored for developers and QA engineers.

      Cypress runs directly in the browser, which allows you to perform tests in real-time with the application running in the real browser environment. This makes test results more consistent. This makes it easier for developers to see test flow and debug errors. Unlike other testing platforms that simulate a browser environment, Cypress runs on an actual browser, ensuring that tests run under the same conditions that users experience. 

      With Cypress, you can take advantage of visual debugging. You can watch how your commands execute and check step by step what is going on. It supports capturing screenshots and videos for easier debugging.

      Cypress offers two options: Cypress App and Cypress Cloud. The first one is just Cypress - a tool for web application testing. Cypress Cloud provides a platform for managing, analyzing, and storing test results, facilitating collaboration among team members and streamlining the testing process across development pipelines. If you’d like to use Cypress Cloud, you’ll have to check the pricing.

      You should consider Cypress when you need an easy solution to test your JavaScript components.

      Katalon Studio

      Katalon Studio is an all-in-one automation testing tool designed to support web, API, mobile, and desktop application testing. As with previous tools, Katalon allows you to record and play back the test. 

      It allows you to write tests with no code. You can take advantage of the graphical interface and just take objects and match them with functions, for example, take name input and match it with Set text function. It's a drag-and-drop solution. It makes test creation, execution, and management really easy and intuitive for both technical and non-technical users. Of course, there is an option to write tests manually.

      What's more the newest feature that is currently in Beta is AI integrations. With that, you can describe what you need to test and the tool will automatically generate tests for you. 
      Katalon Studio offers a free trial, so you can check how it works. Then there is the possibility to use a free account or buy a license.

      This tool is worth considering when you are looking for no code and coded solutions with AI Integration.

      Ranorex Studio

      Ranorex Studio is an environment for automating tests for desktop, web, and mobile applications. You can integrate it with Jenkins, Jira, or TestRail to automate bug tracking - which can speed up your release cycles.
