What Is Test Strategy?
A test strategy is like a guideline for testing software that helps ensure it works as intended. It’s important because it guides the testing process, making it organized and effective. Think of it as a plan that tells testers what to test, how to test, and when to test.
Components of a test strategy include defining the scope, which means figuring out what parts of the software to test. Then, there’s the test environment, like the computer setup, needed for testing. Test levels and types are also crucial, outlining the different kinds of testing to be done.
Additionally, it covers the resources required, such as people and tools, and the schedule for testing activities. Lastly, it outlines the entry and exit criteria, determining when testing can begin and when it’s considered complete.
A good test strategy ensures thorough testing, reducing the chances of bugs slipping through and improving overall software quality.
