How to programmatically skip a

Answer 1

I am not sure if this qualifies as „programmatic skipping“, but in order to selectively skip some specific tests for our CI environment, I use Mocha's tagging feature (https://github.com/mochajs/mocha/wiki/Tagging). In describe() or it() messages, you can add a tag like @no-ci. To exclude those tests, you could define a specific "ci target" in your package.json and use --grep and --invert parameters like:

"scripts": {
  "test": "mocha",
  "test-ci" : "mocha --reporter mocha-junit-reporter --grep @no-ci --invert"
}

Answer 2

We can write a nice clean wrapper function to conditionally run tests as follows:

function ifConditionIt(title, test) {
  // Define your condition here
  return condition ? it(title, test) : it.skip(title, test);
}

This can then be required and used in your tests as follows:

ifConditionIt('Should be an awesome test', (done) => {
  // Test things
  done();
});
