Smoke testing is the Continuous Integration of whatever you test, in this case Perl itself. In the Perl world it is done by volunteers who configure their own computers to build perl and run the test regularly. This is one account on how to configure a machine to do that.
2019.01.15 in #391Untrusted Numeric Input

I found this an excellent post, both because of the content and because of the healthy number of links. Something many bloggers seem to forget.

2022.05.25 in #566What's In That String?

2022.06.10 in #568Core Modules: filetest

2022.07.12 in #573Scalar Context: Lists Versus Arrays

2023.02.03 in #602Annotated Test2::Tools Index
Interesting use case with regard to skip test inside for-loop. Highly recommended.
2023.02.24 in #605Ordering Your Tests
On one hand I think having the tests ordered can be a good idea, but on the other hand we will also want to make sure that the success of the tests does not depend on their order and that they can also be executed in parallel. So I am not really in favor of specifying the order of the test.
