+You know that "Play" with a little something on your IDE that runs only the
+tests? Do you know what it does?
+
+<!-- more -->
+
+A long time ago I read the story about a professor that taught his students to
+code. He preferred to teach using an IDE, 'cause then "students have to just
+press a button to run the tests".
+
+I get the idea, but I hate the execution.
+
+When we get into professional field, we start using things like [continuous
+integration](https://en.wikipedia.org/wiki/Continuous_integration) which,
+basically, is "run tests every time something changes" (it's a bit more than
+that, but that's the basic idea).
+
+Now, let me ask you this: Do you think the students of the professor above
+would know how to add the command to run the tests in a continuous
+integration system?
+
+I know I'm being too picky (one could even call me "pricky" about this) but
+the fact is that whatever we do today, at some point can be automated: our
+tests can be run in an automated form, our deployment can be run in an
+automated form, our validation can be run in an automated form and so on. If
+you have no idea how those things "happen", you'll need the help of someone
+else to actually build this kind of stuff, instead of having the knowledge
+(well, half knowledge, the other half is the CI tool) with you all the time.
