client config in karma.conf.js is overwritten

[buchanae]

In my karma.conf.js I have some mocha config, as described here:
https://github.com/karma-runner/karma-mocha

This line ends up overwriting that config:
https://github.com/karma-runner/grunt-karma/blob/master/tasks/grunt-karma.js#L23

Maybe karma should be merging instead of overwriting, but here's some history to that point:
karma-runner/karma#283

I think grunt-karma should do a deep merge.

Override makes sense in the case of browsers, but not in the case of client. Even client.args should be deeply merged.

This is breaking console.log since karma v0.11.10 due to this change karma-runner/karma@4734962

Setting client: { captureConsole: true } in my Gruntfile or adding --capture-console=true on command line fixes this, however it's not immediately obvious to me how to fix grunt-karma. Even if it does a deep merge of client, the problem is the defaults are being overridden, which suggests a bug in karma-runner.

+1. I spend lot of time figuring out why console.log stopped working a while ago.

Also, the default client config: useIFrame is also overridden to undefined. I'm not sure of the impact

Run into this today myself. I'll fix this tomorrow.
