More specific about what you're storing since you're not storing the Error instance that was thrown.

This should have simply said:

    console.error(ansi.red('Error: No test files found'));

Nothing is gained by outputting multiple error messages, and now we have both warnings and errors with the same message.

They don't show at the same time though (warnings and errors). I mentioned in my comment earlier I felt giving multiple error messages was helpful in those scenarios (in that I found it useful myself).

I'm a bit confused about when we are going to show errors vs warnings...

Wasn't the name of the issue "too much noise if no files found"? Retry one of your tests with lots of nonexistent globs...

I just didn't want to see a warning about it (which duplicated the filenames) and then another error. If that's fixed, then great

Check the description I tried to give full details on what shows when.

I already understand what would be displayed when. Disagreed about what should show for the error case (nothing matched) -- an "n not found" scenario with this code outputs n error messages instead of one. Worse, it uses the exact same message text as the warning case.

process.exit(1);
} else {
// print messages as an warning
errors.forEach(message => {
console.warn(ansi.yellow(`Warning: ${message}`));
});
}

const fileArgs = file.map(filepath => path.resolve(filepath));

test pattern should not be part of check for maintainability. WET due to filename.

Wasn't on purpose, I thought there was nothing outstanding so I merged it.
Have made a new PR continuing (referenced) the work, I think it's more practical to converse there.
