Test::Inline

I recently had the pleasure of testing out Test::Inline, a Perl module that allows for embedding tests within modules. This supplement to traditional .t files is a great way to keep tests close to the specific code being tested.

The process works by writing small fragments of general or function-specific testing code that can be inserted anywhere within the module. These fragments are placed within specific tagged POD segments, such as "=begin testing" and "=end testing label".

One of the best features of this module is the flexibility to add as many or as few chunks of testing code as necessary. However, it's important to note that each chunk should be logically independent of the others and not cause any issues when run before or after another chunk.

To transform these chunks into a complete set of standard Test::More-based test scripts, simply use inline2test or another test compiler. These scripts can then be executed as normal.

Overall, I found Test::Inline to be a useful and efficient way to keep tests in closer proximity to their corresponding modules.
