javascript - Karma: Running a single test file from command line

Question

So, I've been looking all over for this, found "similar" answers here, but not exactly what I want.

Right now if I want to test a single file with karma, I need to do fit(), fdescribe() on the file in question...

However, what I do want is to be able to just call karma, with the config file, and direct it to a specific file, so I don't need to modify the file at all, ie:

karma run --conf karma.conf.js --file /path/to/specific/test_file.js

is it possible to do this? Or with any helper? (using grunt or gulp?)

Answer 1

First you need to start karma server with

karma start

Then, you can use grep to filter a specific test or describe block:

karma run -- --grep=testDescriptionFilter
