Summary

We finally got into something interesting. Not that the previous chapters were less important, but with the tests, we just saw that we are now able to create some conditional statements and let our script react to different situations. It is not just an echo of a variable, but we get to its value, work on it, decide what to do, and act accordingly. In this chapter, we had a quick bite of what flexibility means in a script: it must be a tool and that makes one of the main goals of writing a script: it must be a tool that makes decisions on our behalf and react as we want it to do based on the conditions that we crafted in advance.
