Glob support

[nyurik]

I was trying to adapt test-each-file to my https://github.com/oxibus/can-dbc-pest/tree/main/tests code, which uses large external git repositories with lots of files. My tests are only interested in one extension - .dbc, and with the current set up I have to filter for my extension inside the test function. The test is still generated for each irrelevant file recursively, making the output less useful. A side problem this solves is it ignores duplicates more often, e.g. README files.

Proposal

• MVP: Support globs like "./tests/fixtures/**/*.dbc" - using globset (regex based, possibly faster) or glob (more established?) crate
• Optional: Support exclusions, e.g. "/foobar/" to avoid certain subdirs or filenames. I think globset can help here. This could actually work the same way as .gitignore files - i.e. multiple strings passed to the test_each_path! macro, where if the line begins with the ! it will function as exclusion, whereas everything else includes it

Thx for the great crate!

You should be able to misuse the "file grouping" feature to achieve the wanted effect, like this:

test_each_file! { for ["dbc"] in "./tests/fixtures" => test }

fn test([input]: [&str; 1]) {
    
}

This is not ideal, so I still want to implement globbing support, but may take a bit for me to find the time to do this.

@JonathanBrouwer thanks for a quick reply! How would you use it with test_each_path ? My files are binary. Compiler complains about

the trait `AsRef<Path>` is not implemented for `[&Path; 1]`

BTW, another side ask might be for a test_each_bin_file - but that's a minor improvement

This works for me:

test_each_path! { for ["dbc"] in "./tests/fixtures" => test }

fn test([path]: [&Path; 1]) {
    
}

Could you provide the code that doesn't work for you?

I opened #18 for this
