13 Best Test Automation Frameworks: The 2021 List

Automation frameworks enable automation testers by simplifying the test development and execution activities. A typical automation framework provides an environment for executing test plans and generating repeatable output. They are specialized tools that assist you in your everyday test automation tasks. Whether it is a test runner, an action recording tool, or a web testing tool, it is there to remove all the hard work from building test scripts and leave you with more time to do quality checks. Test Automation is a proven, cost-effective approach to improving software development. Therefore, choosing the best test automation framework can prove crucial to your test results and QA timeframes.

QA’s and Unit Testing – Can QA Create Effective Unit Tests

Unit testing is typically software testing within the developer domain. As the QA role expands in DevOps, QAOps, DesignOps, or within an Agile team, QA testers often find themselves creating unit tests. QA testers may create unit tests within the code using a specified unit testing tool, or independently using a variety of methods.
