Automated Testing
Even though you explored and learned how to debug applications when errors are reported, you would prefer not having 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, you 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 you to record a series of steps and stimuli that you perform in our code and have a series of expected output 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 you keep a record of all those verifications for future modifications of the...
