I'd like to use glob with mocha. Sadly mocha does not support exclude and it does not pass glob options either, so I have to solve this in a single pattern without the usage of the glob ignore option. https://github.com/mochajs/mocha/issues/1577 The other solution would be to use mocha.opts, but that is not karma compatible, I am not sure why. I could define a karma compatible opts file for karma and a node compatible opts file for node, but this will break immediately after the issue is fixed, so I am looking for another solution. https://github.com/karma-runner/karma-mocha/issues/88
I need to match test/**/*.spec.js and exclude test/**/*.karma.spec.js from the results. Is this possible with a single glob pattern?
What we are talking here is the AND("*.spec.js", NOT("*.karma.spec.js")) expressed with logical operators. I checked the glob documentation, it does not support the AND logical operator.
Lucky for us we can transform this operator to OR with negation: NOT(OR(NOT("*.spec.js"), "*.karma.spec.js")). I tried out the test/**/!((!(*.spec.js)|*.karma.spec.js)), but it does not work. It tries to require a module with the test/features path, which is a path of a directory and not a js file, so no wonder it does not manage it. I don't know what kind of bug is that, but it is apparently not working.
Another possible solution to forget this AND operator, and use only negation with NOT("*.karma").spec.js. I tried this out with test/**/!(*.karma).spec.js, which was working properly.
