You need to include some adapter that implements __karma__.start method!

After upgrading karma to 1.1.0, we got the error (Travis Build)

You need to include some adapter that implements __karma__.start method!

I found the problem being this plugin. After removing from the karma config, the tests ran again. To make sinon work without this plugin, I used the configuration mentioned here:

sinonjs/sinon#600 (comment)

Having same issue here after upgrading to Karma 1.1.0

Hi, issue had been fixed in v1.2.3

Please upgrade and check it, thanks!

[callmevlad]

@adambrunner I'm still seeing this issue with v1.2.3 with:

• karma@1.1.1
• karma-chai@0.1.0
• karma-sinon@1.0.5
• karma-sinon-chai@1.2.3
• sinon@1.17.4
• sinon-chai@2.8.0

Any ideas?

[hpurmann]

@callmevlad It's most likely one of the other plugins. Please try to create a minimal use case which only uses karma-sinon-chai.

I'm also having this issue and I have the same dependencies as @callmevlad. In my config I commented out sinon-chai and that fixed it so I believe it is still something with this module. I'm not even running my tests through CI, this is running locally, and I've just started the unit tests on a new project so I only have one test that does some really random assertions just to make sure all my configuration is working properly so I can start writing a test suite.

Here is my frameworks in my config:

frameworks: [
    // 'sinon-chai',
    'sinon',
    'chai',
    'mocha'
]

I'd be happy to provide any information you deem fit to try and help resolve this.

aaaaaaand foot in mouth, removing the other frameworks from my frameworks array and using just sinon-chai works fine :\ Thats what I get for copy pasting configs, realized this only when I pasted my own frameworks in the prior comment a minute ago, sigh.
