Should not throw error when files.length == 0

[mariodu]

Directory structure likes below:

tests/
    units/

In units, there isn't any file. When I use mocha to run this path, it throws can't resolve path, but glob(path) returns []. Maybe, it shouldn't throw error.

tests/
    units/
        lib-test.js

If directory structure likes above, it works well.

Thanks for the PR! How are you invoking mocha given the dir structure above to trigger the exception?

[mariodu]

like:

mocha --reporter spec --recursive --growl -t 0 ./test/units/*-test.js

This also happens when you invoke mocha without specifying folder / files, and there's no test folder, or there are no files under the folder. It's a common case when starting a new project using a boilerplate, and you don't want to bother with tests just yet because you're experimenting and changing how things work very fast.

Can this be rebased and merged?

[Munter]

I think #2450 already covers this case

[knownasilya]

Is that in the latest version?

[Munter]

I don't think a release has been made yet. It just got merged into master

@Munter should this be closed? if so, please do

[Munter]

I think it should. If I'm wrong and this error case is not covered by #2450 then please reopen
