karma-electron crashes when using electron version 1.4.3

[etiennejcharles]

When using electron version 1.4.3 this is the error I get.

I reverted to version 1.4.2

And my tests now again pass.

Do you get the same error?

I'm seeing failures in 1.4.3 as well yet 1.4.2 is passing. I don't see any relevant issues since 1.4.3's release. I've done a little bit of debugging and it looks like something in Karma's setup as loading http://google.com/ works fine.

I moved to launching Karma in its continuous mode and launching electron directly. This is the error we are getting:

$ ./node_modules/.bin/electron lib/electron-launcher.js --url http://localhost:9876/

  throw err;

I'm going to try setting up a minimal gist to reproduce the error and opening an issue on electron.

Alright, the issue has been reported in https://github.com/electron/electron/issues/7519. For now, I suggest sticking to Electron@1.4.2

@etiennejcharles I'm having the exact same issue. Thanks for reporting it and the downgrade suggestion.

@twolfson Thanks for the detailed trace of this issue! I've learned from it. :)

Electron@1.4.4 has been released and it looks like the issue has been resolved. Closing this issue
