What's the reason behind this PR? This is a development dependency so it only affects testing. However, if we want to expand coverage of our testing with respect to Electron, then we should add tests for the past 2 major versions as well (e.g. 0.35.x, 0.36.x)

[twolfson]

As a heads up, this package currently chokes at requiring submodules in the same context as the same window scope.

We have patched it by switching to window.open in https://github.com/twolfson/karma-electron/tree/dev/fix.nested.context but that requires a patch from karma which is being reviewed:

karma-runner/karma#1984

[ppitonak]

The main reason for this PR is that I consider it a good practice to test with latest stable release. In the case that Electron team supports multiple streams, it makes sense to run tests on all stable releases.

[twolfson]

I don't believe Electron offers multiple streams but we could set something up in Travis CI that does npm install electron-prebuilt@version based on environment variables.

That being said, I don't have time at the moment to take that on so I will land this PR as is =/

Thanks for the quick response

This has been merged/released in 3.0.5 (patch release since it doesn't affect non-development usage)
