Automated testing
Even though we explored and learned how to debug applications when errors are reported, we would prefer not to have to find errors in our applications. To increase the chances of having a bug-free code base, most developers rely on automated testing.
At the beginning of their careers, most developers will just manually test their code as they develop it. By just providing a set of inputs and verifying the output of the program, we can get a basic level of confidence that our code “works”, but this quickly becomes tedious and does not scale as the code base grows and evolves. Automated testing allows us to record a series of steps and stimuli that we perform in our code and have a series of expected outputs recorded.
This is extremely efficient to reduce the number of bugs in our code base, because not only are we verifying the code, but we are also implementing it, and we keep a record of all those verifications for future modifications of the...
