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?)
This question is related to

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
see https://github.com/karma-runner/karma/issues/1731#issuecomment-174227054
The files array can be redefined using the CLI as such:
karma start --files=Array("test/Spec/services/myServiceSpec.js")
or escaped:
karma start --files=Array\(\"test/Spec/services/myServiceSpec.js\"\)

Even though --files is no longer supported, you can use an env variable to provide a list of files:
// karma.conf.js
function getSpecs(specList) {
if (specList) {
return specList.split(',')
} else {
return ['**/*_spec.js'] // whatever your default glob is
}
}
module.exports = function(config) {
config.set({
//...
files: ['app.js'].concat(getSpecs(process.env.KARMA_SPECS))
});
});
Then in CLI:
$ env KARMA_SPECS="spec1.js,spec2.js" karma start karma.conf.js --single-run
