Coverage files are created for anonymous functions in package tests…

… if the anonymous function is called by code defined in the package and (edit: this is no longer true on master) if the anonymous function is defined outside of a @test macro.

Typically coverage is not reported for lines in test files at all. But in this particular case, you end up with spurious .cov files in your test folder. Not a huge deal, and can generally be ignored, but we are otherwise so consistent about ignoring such coverage lines that this edge case feels a little buggy.

MWE: https://github.com/mbauman/TestTestCov, with tests run simply by activating the package environment and doing a ]test --coverage. If myall were only called inside @test macros, no .cov file would be created in the test folder at all.

We should be making files for all of them, that is a bug. Use the syntax to make .info files if you don't want them cluttering your filesystem.

Sure, I'd be fine with the fix going the other way, too. But then we should also simply count traversing all the lines in the test files, not just those that are a part of a function body, yeah?
