The macOS file system is case insenitive but case preserving, so if you have a directory named `test` in your project (which is standard) and you try to add the `Test` module (which you need to do testing), you get the following error (1.4.0-rc1.0):

```nohighlight
[ Info: Resolving package identifier `Test` as a directory at `/path/to/Project/Test`.
ERROR: Did not find a git repository at `Test`

```

That’s because the `test` directory is interpreted as a directory named `Test`, which then collides with the module name, and Julia blithely starts looking for the module there.

The workaround is to add the `Test` module before you create the `test` directory, which is not a problem – but perhaps one might wish to address this, somehow? E.g. somehow handle case issues on macOS or at least have a tailored error message specifically for `Test` where this collision is bound to occur for every project with a standard test setup on macOS, unless you do things in the right order?

And creating the directory first isn’t that unnatural. After all, if you try to run `test` in the package manager, you’re told the directory (with `runtests.jl`) is missing; then you add the directory and file, add `using Test`, and then you’re told you don’t have the module in your dependencies. Then you try to add it, and it fails…
