You know that "Play" with a little something on your IDE that runs only the
|
||
|
|
tests? Do you know what it does?

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.
