Karma Debugging - No debuggable browser found 关注

One other thing: This happens both with the Karma test runnner and with the NodeJS runnner.

Hi,

I have just installed IDEA 13 on a windows 7 machine. I have managed to get Karma test debugging to work about 5 times. Now it pretty much always fails with a error message in the event log: "17:11:30 Error running all: No debuggable browser found"

Please try to debug JavaScript in HTML using "JavaScript Debug" Run Configuration.
If debugging is successful, then Karma tests should also be debugged.

Even when I kill all the running karma tests I often find node.exe and phantomjs.exe running in my task manager

To kill node.exe process you need to kill Karma server (there should be a tab named "Karma server").

The regular javascript debugging works fine and correctly hooks into the Chrome debugger.

To kill node.exe process you need to kill Karma server (there should be a tab named "Karma server").

I have tried this. I have even tried closing IntelliJ IDEA and Chrome. In some cases I still see the process there.

Thanks for the info. Well, I'm puzzled.
Could you please attach here a file with content of 'Karma Server' tab?
If possible, please attach idea.log (on the main menu Help | Show Log in Explorer).
Thanks!

WIll try to reproduce the issue on Windows.

Here are the files you requested.

Note: I was able to get the debugging to work once as a NodeJS application, and then it started failing again.

HI,

I have just made an interesting find.

If I:

1. run the NodeJS runner called 'Karma Run',
2. then make sure that the 'open browser after launch' feature is enabled,
3. then I manually press the karma 'debug' button in Chrome,
4. and then I manually setup a javascript debug runner then it works.

So it seems the problem is in how the IDEA automates the whole thing.

cheers,
Florian

PS: at least I have a work around now, clumsy, but working

According to idea.log, PhantomJS was captured as a slave browser in your karma tests.
Karma tests debugging is working only in Chrome and Firefox.
Just capture one of this browsers and try again.

That was it. Cool.

:)

Merry Christmas

Good to hear that!

Merry Christmas!
