Karma clear screen before running tests

Question

I use karma to run jasmine specs. Every time a file changes the tests are run. This is awesome but it would be even better if the previous test output would be removed from the terminal.

Is there a way to clear the terminal before tests are run in karma?

Answer 1

It is not supported. I like this idea though. I created issue #1004 to support this.

Answer 2

The issue @Sylvain has created is still open, but there is a plugin karma-clear-screen-reporter which does the job. Internally it uses the magic:

console.log('\u001b[2J\u001b[0;0H');

Alternatively you can also place this at the top of your test runner code to clear the console yourself.
