What is automation testing and why is it used?
This is a very basic question - automation testing is used when you are using test automation frameworks (and tools) for running tests. Use automated tests when you want to run tests that do not require manual intervention.
Selenium, Cypress, and Playwright are some of the widely used test automation frameworks for UI testing. Similarly, Postman is used for API automation testing.
Apache JMeter, LoadRunner, LoadNinja, and WebLOAD are some of the popular load testing tools for automated load testing. Automated testing reduces time involved in test case execution since manual intervention is not involved in the test process.
