TypeError: 'null' is not an object (evaluating 'currentSpec.expect')

[danielbsig]

The following error occurs occasionally (not always) when we run our tests using gulp-karma. However, if the tests are executed using karma alone, this does not occur.

Seems to be a problem on Windows only.

Any ideas what might be the problem?

currentSpec.expect is part of of Jasmine, so this could be a problem with your Karma plugin configuration or Jasmine itself... It is odd that the behavior is only observed when running with gulp-karma, but I can't think of a reason why that could ever happen due to what gulp-karma does.

it might have something to do with the gulp.src we're passing. Is it possible to use the file array defined in karma.conf.js?

[lazd]

The plugin is in flux right now and will definitely not be using gulp.src() to specify files in the future. See karma-runner/karma#1037, where @pkozlowski-opensource and I discuss that this plugin really shouldn't exist, we just need a few features in Karma to make it usable directly from gulp.

The problem is probably in some other component (karma-jasmine or jasmine itself), so I will close this issue.
