In the 1980s, Software Testing was performed manually by all the organizations. Then, at the beginning of the 1990s until around 2003, the first usage of test automation came into existence by using sophisticated tools called as Test Automation Tools. Over the period from 2004 till 2009, multiple tools started evolving and open-source projects, which are developed by test enthusiasts, started becoming very popular and many people started to adopt new tools and strategies till the last decade and of course until today. The future of Test Automation is going to revolutionize the way the test automation happens today. Artificial Intelligence will be on its peak and many organizations will start adapting the AI-based test automation tools for their testing.
