Top 10 QA Automation Testing Tools in 2021

In this fast-evolving world of software development, where technology is taking a new turn every day, automation proves to be a significant way of normalizing things. For every product development, automation testing acts as the assurance of a quality product at speed. Moreover, with agile development and DevOps methodologies in the picture, organizations are taking a massive leap towards CI/CD pipeline to improve product deliveries to the market.

Test automation is the sole essence of these aspects, as it reduces testing times, tracks bugs quickly, improves delivery cycles, and focuses on other areas of your product. Another added advantage of test automation is that it doesn’t require human intervention and save a tremendous amount of time. The prime purpose of automation testing is to shorten testing times and offer better test coverage of a product. 

However, automation testing is not feasible without a QA automation testing tool, which is required to generate and execute test scripts. Although thousands of testing tools are available in the market, choosing one that fits your requirements is quite challenging. Selecting the right automation tool is essential to deliver a quality product at speed.

This article talks about the top 10 QA automation testing tools you should opt for in 2021 to quickly maximize your test coverage and deliver products to the market.
