- [x] Other (please describe): Testing
What is the current behavior?
At present there is no easy way to test the stencil compiler end-to-end.
The stencil compiler is the main backbone of stencil - designed to run on a fileSytem on disk, it collects a bunch of input files and outputs different bundles according to the outputTargets defined in stencil.config.
What is the new behavior?
A new 'mock-compiler' suite has been added. This sets up a series of 'sensible' config defaults, setup files (all of which can be overwritten) and a hybrid fileSystem which can read real files on disk whilst writing all new files to memory.
Does this introduce a breaking change?
- [ ] Yes
- [x] No
Testing
I have re-written 7 (currently defunct) legacy compiler tests to use the new mock-compiler. They all run and pass.
Other information
Any reason this one went under the radar? Feel it was a quite small risk to quite a large potential reward ratio :) The reason I made it originally was to demonstrate some bugs and write tests for the fixes I made to the stencil plugin flow.
@johnjenkins you're right - the reward is pretty large here and having these tests back up and running is something we've been actively talking about. @alicewriteswrongs is doing some work around the dist-custom-elements output target, and is probably feeling this pain quite a bit right now. Once that work is complete, we plan to circle back to this and take some of the things she's learned from working on that output target into account (but Alice can correct me if I'm wrong here)

--strictNullChecks error report
Typechecking with --strictNullChecks resulted in 2363 errors on this branch.
Unfortunately, it looks like that's an increase of 89 over main 😞.
