Today, software testing plays one of the key roles in the process of creating, as well as maintaining a high-quality and popular IT product. The experts of our company tried to find out the positive and negative sides of the most popular functional testing tools.

Selenium

Selenium is a true old-timer among all functional testing tools. Its history began in 2004, and now it is considered the most popular tool in its industry. Despite the widespread use of Selenium by such giants as Google, it still has a number of disadvantages. Perhaps the main one is the need for advanced programming and scripting skills to fully work with the product, which, in turn, often makes it difficult for novice testers to master the tool. But Selenium is distributed absolutely free, supports a huge number of languages ​​for writing scripts, and is also a cross-platform tool, and for this, it is impossible not to love it.

Pros:

Cons:

Katalon Studio

Katalon Studio is another very popular tool for automating the testing process. Just like Selenium, it is a free, cross-platform product, however, its target audience is just novice QA engineers because Katalon Studio has such functions as simplified scriptwriting and testing using keywords, which in theory should greatly facilitate automation for beginners.
But this tool also has some drawbacks, among them: a meager choice of programming languages, as well as the lack of detailed reports.
In any case, Katalon Studio is a worthy tool and will undoubtedly be in demand in professional circles for many years to come.

Cons:

UFT One

UFT is a commercial functional testing product developed by Micro Focus. Its undoubted advantage is the presence of a number of functionalities that make testing easier and more efficient. For example, UFT has the rare feature of updating the interface with minimal script changes, which saves QA engineers' time in case of UI changes. Also, this tool has a wide range of tested applications and can be applied to the web, desktop, and mobile applications. However, working with the tool is possible only within the Windows OS, and for writing scripts you need to use only VBScript.

Pros:

Cons:

IBM Rational Functional Tester

IBM RFT is a paid functional software testing tool from IBM.
In terms of useful functionality, it is not inferior to UFT. For example, the main feature of IBM RFT is the Storyboard testing feature, which allows you to record and visualize all user actions related to automated testing. The generation of detailed and elegant test reports is another big plus of this product. Two scripting languages ​​are supported: Visual Basic, .Net and Java, which significantly expands the range of users when compared to UFT. Moreover, this tool is cross-platform and will work equally well on Windows, Linux, or OS X.
RFT easily integrates with other IBM products, such as IBM Jazz, a lifecycle management system, to improve the quality of the final product.

Pros:

Cons:

TestComplete

TestComplete from SmartBear is an effective commercial testing tool for desktop, mobile and web applications.
Its main drawback is, perhaps, that it is available only for Windows OS. But this tool is one of the few that can compete with Selenium in the number of supported languages. Test scripts can be written in JavaScript, Python, VBScript, JScript, Delphi, C ++, and C #.
TestComplete has a UTF-like GUI object recognition feature that can automatically detect and update user interface objects. This will significantly reduce the cost of maintaining test scripts when the interface changes.

Conclusion

The above description of the tools is not exhaustive. For sure, each of these tools should be used in accordance with your goals and experience.
