TOP 7 efficient app testing tools for 2021-22

Nowadays, we’re facing an exponentially growing number of apps. Only in the first quarter of 2021, the Apple App Store counted 2.22 million available apps, while on Google Play Market they were in a number of 3.48 million. (Statista)

Due to the fact that the competition is high, obviously, there is a huge demand on them to provide a top user experience journey. To ensure apps’ workability and efficiency, the development team, namely quality assurance engineers, continuously improve apps, fix bugs by regular tests. Clearly, tests are the key aspect that ensures apps’ security, scalability, functionality, accuracy, and many others that offer the user a great experience.

To run comprehensive app check, QA teams rely on manual testing, web testing, browser testing, regression testing, and API testing, and more. Regrettably, this process is time-consuming. Therefore, quality assurance engineers’ resort to certain tools in order to carry out automated tests.

To clarify which tools are more practical, more effective for testing applications in 2021-22, we realized comprehensive market research and came up with an integrated analysis on this topic.  You’re curious? Let’s see what each of them represents.

Selenium framework is intended for testing web applications on various browsers and platforms such as Windows, Mac, and Linux. Selenium helps QA engineers to write tests in different programming languages ​​such as Java, PHP, C#, Python, Groovy, Ruby, and Perl. Moreover, this tool offers recording and playback functionality for writing tests without learning the Selenium IDE (Integrated Development Environment). Selenium proudly supports some of the largest, well-known browser vendors who are confident that Selenium is a native part of their browser.

If we refer to its advantages, we emphasize the flexibility, additionally the ability to write complex and efficient scripts to test the applications. On the other hand, in order to start working with Selenium, the tester must have extraordinary knowledge of programming and be ready to devote some of his time and energy to writing special frames and libraries that provide specific functions during the testing process.

Thus, each of these tools allows QA engineers to conduct a complete quality assessment, identify all errors, and bring the software to perfection. However, it’s worth noting that smart testing and smart analytics for adaptive and heterogeneous environments are something that has yet to be implemented in modern test automation tools. From our side, we suggest to find a balance between manual and automated tests.
