neat! looks like a good start -- with some tests should probably be good enough as a v1 implementation!

Any hints for getting up to speed with writing the tests as easily as possible? :)

Sure!

For this I think there's ~two main tests you'll want to add:

1. an integration test which tests a language: perl repository -- you can add a repository in testing/resources/... (there's quite a few examples there) -- and then you'd hook that up with a test in tests/repository_test.py (here's an example for rust)
2. an integration test demonstrating additional_dependencies -- I'm less familiar with how you'd do this with perl, one easy way might be to define a local-like configuration and ensure that the additional dependency gets installed -- maybe something like this golang test

depending on what's out-of-the-box on azurepipelines we'll probably also need to install perl (?)

if you get stuck I can probably help -- but you'll need to teach me a bit about perl package management :)

Thanks, I'll have a look. Additional deps already worked when I tested them -- there are multiple ways one can specify them for cpan to install, but the most usual one is just a module name.

I have no clue about perl in azure, and I'm more familiar with travis anyway, but I don't think it will be a problem at all, just something one needs to add.

One future improvement would be to support repos with cpanfiles in them -- for that one would first make sure either carton (especially if cpanfile.snapshot also exists) or cpanm is installed or install them if not, then proceed with using them. But repos with are less common, let's first get the baseline done.

Ok, got those implemented. Linux ok locally and in Azure, but tox_windows py37 fails writing a state file there or something, or maybe it's a result/side effect of something else. I guess it's a fair assumption that perl isn't installed in Windows there, but dunno if it could cause something like that.

I'm afraid I'll need someone to look into this.

I believe I've fixed windows 🤞 -- played around this with a VM -- it also looks like azure pipelines preinstalls "strawberry perl" so perl should already be available

🎉 thanks for the patch!

this has been released as part of v2.1.0 -- thanks again!
