Pro: Test without a Plan

We left the previous article with a small issue involving lack of DRY-ness.

The slight problem was, that we hard-coded the number of tests in the use Test::Simple tests => 5; expression. If we now add a new test-entry to the @cases array, we have to remember to update the test plan as well.

Not a big issue, but we as programmers are supposed to avoid any such repetition. So how can we do that?

Finding all Plack Middleware or Perl::Critic Policies

Recently I was working on a patch for MetaCPAN, but then it turned out that I don't need to implement it as it is already working. I wanted to be able to list all the modules within a namespace. Apparently it is very easy. I only need to prefix my search with module:

Pro: What is the status of the current test script?

The other day I looked at the tests of the Expect module, and was surprised to see that it was still using the old-style, home-brewed testing system. Something like the one we used when we introduced test automation. I wanted to convert it to use Test::More, but in addition to an ok() function, this home-made system had a unique functionality.

At the end of the script it printed a message something along the line "Don't worry if a test fails, this can happen.", but it only printed if any of the ok() functions of the test script failed.

I wanted to preserve this functionality.
