Re: Unit testing under GJS

[Edgar Merino <donvodka gmail com>]

Hello, I've updated the repository for the extension, Karma is no longer used for testing, jasmine-gjs is used instead. This is even working with Travis CI (although it runs on a pretty dated gjs version, 1.40). Transpiling should now be optional, and testing is a lot let hackish (e.g. you no longer need a full browser implementation like PhantomJS and Karma) and it's running under native GJS.

Webpack is still used, which requires a build step before testing to generate a single test UMD module. This makes executing a single test file impossible right now, they all have to be executed at once.

Using Andrea's cgjs, webpack can be avoided, it'll make all NPM modules available in a more native way. Also, tests can be run individually, which is an added benefit.

Next step would be to give cgjs a try to use require instead of the native imports mechanism of GJS.

Regards.

Hello Andrea, CGJS looks promising, it actually solves what I was missing/patching, and it can be easily integrated with WebPack (which in turn provides ES6 imports through UMD, if needed/preferred).

To eliminate transpiling completly when testing, currently you can use firefox, but a better option would be something like jasmine-gjs. I'll give this a try and report back, this should also eliminate the dependency on Karma, which is mostly a hack here, but there's got to be some work done to integrate that with webpack (needed mostly for ES6 imports).

I'll see if plugin-transform-builtin-classes helps, thanks for the tip!

Regards.

Babel transpiling builtins is broken since ever: https://github.com/babel/babel/issues/4480

I wonder if using https://github.com/WebReflection/babel-plugin-transform-builtin-classes would help

Also please have a look at cgjs which brings CommonJS to GJS:

It'll be great to read your thoughts on this approach.

Thank you for putting the effort into doing this.  This is pretty neat concept.  At one point, a couple years ago I was trying to figure out how to do testing on extensions as a whole as part of the release process.  The test was a basic "Does it work?".  But having a mechanism to do unit tests would be pretty handy especially if it could be incorporated as part of the submission process.  So from a policy perspective I think this is pretty awesome.
