There's a bunch of generated files that webpack relies on to work, and Karma works off webpack. To make both happy we've added
a new `build:genfiles` script which takes care of this for us. We also have to install and build our other layers to get the
same effect (like generating the react-sdk's component index, while we still have one).
This commit also fixes all the imports in the tests because they were just wrong. They should have been caught in the ES6ification
earlier, but were missed.
Most `npm` operations are replaced with `yarn`, which generally has better
behavior. However, steps like publish that write to the NPM registry are left to
`npm`, which currently handles these tasks best.
- rename test:multi npm target to test-multi, for consistency with react-sdk
- base karma webpack config on the distribution one
- include Olm if we have it
- don't use the karma source loader - it's pointless given we webpack
everything.
- turn off module listing in the webpack stats to shorten the console output
If olm is not installed, the webpack build for the karma tests gives an ugly
error. None of the tests currently care if olm is installed or not, so fix this
for now by just ignoring the olm module.
* Make sure we only get one js-sdk (and update runtime config to match)
* Don't verifyNoOutstandingRequests (since it is hard to be certain which we
will get, and makes the tests too dependent on implementation-specifics).
* Disable color for npm test, to avoid confusing Jenkins
