If you are a beginner, or would like to refresh your Perl programming knowledge,
you can go over the Perl tutorial or watch the
Beginner Perl Maven video course.
If you need to maintain a large piece of software written in Perl by other people in the last 5-10-15 years,
that's a challenge. Especially if you did not get proper training in Perl. You are probably limited to
a specific and old version of Perl. Check out, the Perl tutorial!
You can probably skip the part about installing Perl, but the rest of the tutorial will be relevant for you.
Perl is often used in Test Automation. If you work in this field, or if you'd like to work in this field
(it is much more fun to find bugs in other people's code than in yours :), then you can read the Perl tutorial
and the series on Test Automation using Perl.
If you build new web applications - either privately or inside a company - you can start by reading the
article comparing CGI, mod_perl and PSGI. From there you can go on reading
the generic Perl tutorial or the articles on
Mojolicious, Perl Dancer, Catalyst,
PSGI/Plack, or even CGI, the Common Gateway Interface, for old-school web applications.
In the off chance you are interested in topics other than Perl, especially related to Test Automation, Continuous
Integration, Continuous Deployment, DevOps, then you are welcome to check out the list of
DevOps related training courses.

Refactor test cases of the Markua Parser in Perl 5
Earlier I've mentined that I don't like the fact that we used copy-paste in the test script and duplicate code. Before we go on and add more test, let's refactor the test code.
