API for filtering executed tests

Karma IDE integrations’ users would benefit from the opportunity to be able to run single test / test suite / test file only.

At the moment it’s already available for karma-mocha adapter through passing client argument (--grep).

Also it’s possible to run single Jasmine spec/suite through editing source code (iit/ddescribe). Seems source code editing could be avoided if a new preprocessor would insert iit/ddescribe in the result file at proper offset that is served. Maybe better solutions for Jasmine exist.

How about having a common universal API on Karma level (JavaScript API or a new cli option) for filtering executed tests by test name / test suite name / test file name?

@dignifiedquire I’m working on a very large app with ~5k Mocha tests loaded via RequireJS. While it’s true that we can run specific tests using Mocha’s --grep, the feature is crippled because RequireJS still loads our entire test suite… So even running a single test takes around 10-20 seconds.

It would be very powerful if Karma provided some way to modify the window.__karma__.files array before starting the test run.

--grep can be handled as regexp after https://github.com/karma-runner/karma-jasmine/commit/3b20480a5a1cfa769c2a1861455c76d3bfaaab52
