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.

Formatted printing in Perl using printf and sprintf

printf can be used to create a formatted print to the screen.

sprintf accepts the same parameters, but it will return the formatted string instead of printing it so you can collect the string and print them later, or save them to a file or send them in an e-mail.

Test2 capture warnings

When you write test you might have tests cases that pass, but at the same time your code might generate warnings. Some of these warnings might harmless, but other might indicated some problem. Either in the application under test or in the tests.

In addition if someone looks at the output and sees warnings, the person rightly will be worried that there might be issues with the code.

If nothing else then that using it will fill the log files of a web server causing denial of service.

The problem is that a warning does not stop the tests and so new warnings might not be noticed in a CI system.

Let's see how to get started with it, or more specifically with Test::V0.
