Code-Maven series

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.

The value of a clean Continuous Integration (CI) system (for Data-Trace)

One of the difficult things while introducing Continuous Integration (CI) on a clean environment is convincing people that there is value in it. I got lucky when I was adding GitHub Actions as a CI system to the Data-Trace distribution as I can now demonstrate the value.

Adding GitHub Actions to Test2::Harness::UI

Test2-Harness-UI is a web interface for viewing and inspecting yath test logs. It is still in development, but it (obviously) has some tests. Those tests will be executed by the CPAN Testers after a new version was released, but we can shorten the feedback cycle by configuring a Continuous Integration (CI) system.

On GitHub it is usually GitHub Actions.

Using GitHub Actions (CI) to locate missing test dependencies in Dist::Zilla::PERLSRVDE

Earlier we saw how to Add GitHub Actions (CI) to a Perl module that is using Dist::Zilla. This time I tried to do it another distribution found on CPAN::Digger.

I found out that the command I used to install the dependencies did not install several modules needed for testing.
