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

This option is no longer supported in recent versions of karma:

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\(\"test/Spec/services/myServiceSpec.js\"\)

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

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
