'should.and' failing with 'karma@0.13'

[AlexKVal]

This spec-code

var methodTest = sinon.stub();

methodTest('y');

methodTest.should.have.been.calledOnce
    .and.calledWith('y');

causes

✖ validates each validation
      Chrome 43.0.2357 (Mac OS X 10.9.5)
    TypeError: Cannot read property 'and' of undefined

with karma@0.13 version.

I've created simple project for bug repro:
https://github.com/AlexKVal/karma-test

master branch uses karma@0.13 and causes test fail
karma13 https://travis-ci.org/AlexKVal/karma-test/builds/71240835

https://github.com/AlexKVal/karma-test/tree/karma12 branch uses karma@0.12 version and works fine

Thanks for the report, will try to take look as soon as I can

It looks like the underlying issue is the same as #1499. There is a conflict between the karma-chai and the karma-sinon-chai plugin. They both include a version of chai, and in 0.12 the addition from karma-sinon-chai simply won, but for some reason this broken now. You can work around it for now by removing karma-chai, which isn't needed anyway.

Thank you @dignifiedquire for the hint about karma-chai. 🍒
Indeed it helps with tests. ❇️

Now all is left to migrate react-bootstrap to karma@0.13 is #1497, which as I can see is also caused by the new file loading mechanic.

Fix was released in 0.13.1
