10 Best Automation Testing Tools in 2021

Automation testing is the process of running software programs that can automatically execute test cases and produce the test results with tools, eliminating the need for human intervention.

It is usually carried out after manual testing, saving the company the time and scope of human errors up to a great extent. Once activated, automated tests can be run any number of times to test the same application, thus decreasing the tautological manual work.

The demand for automation is increasing everywhere, also in the software testing industry as well. Every software or application testing community (i.e., uTest, Subreddits, etc.) on the internet are talking about the new or better tools for day to day testing activities.

There is an increasing need for automation in software testing since we are evolving into a world where everything is digitizing, and there is never a lack of competition. Hence, there is no room for error for developers, nor they have much time to waste. 

Let us check out the top 10 best automation testing tools for software testing, which can ease the life of developers and testers:

1. Selenium
