One of the most important stages in the software development process is thorough testing of all components of a future product. The requirements for speed and quality of testing are constantly growing, but at the same time a large number of operations are still performed manually. Therefore, businesses often have to increase the size of the testing team in order to speed up the development, which entails an increase in total workload and project costs. The startup project of our client was supposed to be a solution to this problem, by automating the testing process of web applications. The developed solution should have allowed to fully automate the testing process, conduct testing of several web applications or their components simultaneously, 24/7, reduce time and money spent on this process and improve its quality by eliminating the human factor.
