Please provide examples and consider adding builtin support of TypeScript specs for mocha or jasmine testing frameworks. Or just add support for custom options passed to mocha like config from webdriverio:

mochaOpts: {
  ui: 'bdd',
  compilers: ['ts:ts-node/register'],
  requires: ['./test/helpers/common.js']
}

We can do that easily. Just need to allow users to add configs to Mocha.

Note to self, this is the line: https://github.com/xolvio/chimp/blob/master/src/lib/mocha/mocha-wrapper.js#L13

@samhatoum great, thanks! As workaround now I run TypeScript compiler before running tests, but seamless integration is usually better for interactive development.

Well you can pass custom mocha CLI options now (e.g. via chimp --mocha --mochaCommandLineOptions '{"compilers": ["ts:./scripts/setup-ts-node"], "watch-extensions": ["ts"]}, but the problem currently is that chimp is explicitly allowing only .js files to be executed (as per https://github.com/xolvio/chimp/blob/master/src/lib/mocha/mocha-wrapper.js#L41). This checks needs to be adjusted with the passed watch-extensions from mocha with the .js fallback (and maybe use String.prototype.endsWith instead)

Haven't checked jasmine or cucumber so far.
