This PR just remove the single file from testing so currently dub does not run unit tests in the single file package at all. The first variant (https://github.com/dlang/dub/pull/2050) fixes the issue indeed. I need to reevaluate these PRs and close the issue. I'll do it later.

Thanks for taking a look.

Not at all.

But what do you mean exactly by "work with dependency"? As I understand, `dub test` does not run unit tests in dependencies and single file packages work with dependencies in general. Do you mean something else? I'm finishing the new PR to fix #2051 finally and I'd like to know if there is something else I should include in it.

Thanks. It looks like your UT with taggedalgebraic does exactly what I was looking for.

My problem is that run.dlang.org will skip unittests when you have dependencies. I had made some progress on fixing this a few months ago [1], but put it on the back burner when I ran into similar issues that the OP was dealing with. The problem ultimately came down to dub test not working with --single, which it looks like this latest PR will fix for good.

Ah, I see. Then I would say that `dub test` doesn't run unit tests from the main source file (where the main function is placed). And this is the reason, I guess. Now `dub test` runs unit tests from the main source file if the package is a single file one. I think that dependencies is irrelevant here, at least I didn't do anything special for them. Let's see what happens.
