9.2 Test automation

One of the most significant innovations in agile software engineering is automated testing, which is now widely used in product development companies. Automated testing (Figure 9.4) is based on the idea that tests should be executable.

You run the test and the test passes if the unit returns the expected result. Normally, you should develop hundreds or thousands of executable tests for a software product.

A diagram represents automated testing. Code being tested, files of executable tests, and testing framework are fed into a test runner to generate a test report.
