Enhanced knowledge of popular and highly acclaimed testing frameworks goes a long way in developing a new app. It holds more significance if you are a full-stack developer or expert programmer.

Fault-Based Testing and the Pesticide Paradox

In some sense, testing can be more difficult than coding, as validating the efficiency of the test cases (i.e., the ‘goodness’ of your tests) can be much harder than validating code correctness. In practice, the tests are just executed without any validation beyond the pass/fail verdict. On the contrary, the code is (hopefully) always validated by testing. By designing and executing the test cases the result is that some tests have passed, and some others have failed. Testers do not know much about how many bugs remain in the code, nor about their bug-revealing efficiency.
