Watching doesn't start when debugging

[abaksha-sc]

May be just change event run_start to listening ?
https://github.com/karma-runner/karma/blob/bb022a7fa06042eb0d98ed72c75b74038128d9c0/lib/server.js#L175

It dispatches when karma server is ready (see previous line with this.log.info). Here is a documentation for this: http://karma-runner.github.io/3.0/dev/public-api.html
I think it is a good point to start watching.

P.S. I tested this solution, it works with --no-single-run --no-browsers

Ahh I see, the listening event was added in Karma 2.

I'm in the process of adding support for [email protected] so I'll make sure this issue is resolved in the next release: [email protected] coming soon...

Do you know which flag prevents the run_start event?

There are two flags prevent run_start: --no-single-run --no-browsers

1. Here is event fires when config.noSingleRun:
https://github.com/karma-runner/karma/blob/bb022a7fa06042eb0d98ed72c75b74038128d9c0/lib/server.js#L311

But I use flag --no-single-run

2. And here are event fired when capturedBrowsers is not empty:
https://github.com/karma-runner/karma/blob/bb022a7fa06042eb0d98ed72c75b74038128d9c0/lib/executor.js#L30
https://github.com/karma-runner/karma/blob/bb022a7fa06042eb0d98ed72c75b74038128d9c0/lib/middleware/runner.js#L38

But I use flag --no-browsers.

Because of this event run_start doesn't fire when I open debug.html directly.
Event fires when I open http://localhost:9876/. But it is a redundant step for me (and my colleagues).
