* bump lightningcss
* use `lightningcss` in the main PostCss Plugin
* use lightningcss in our custom matchers
Now that we are using `lightningcss` and nesting in the new `oxide`
engine, the generated output _will_ be different in the majority of test
cases.
Using a combination of `prettier` and `lightningcss` will make the
output consistent.
The moment we are fully using the `oxide` engine, we can drop
`lightningcss` or `prettier` again to improve the performance of the
tests.
* update tests to apply `lightningcss` related changes
* update changelog
* add `lightningcss` and `browserslist` as dev dependencies to stable package.json
* only use `lightningcss` in tests (without prettier)
We will only fallback to prettier if lightningcss fails somehow.
* apply side effect chagnes due to only using lightningcss for tests
* make CI happy (integration tests)
Apply changes to integration tests now that we are using lightningcss
* transform `lightningcss` for Node 12 when running tests
* run prettier on failing tests for `toMatchFormattedCss`
This will result in better diffs because diffs are typically per block
and/or per line. But lightningcss will simplify certain selectors and
the diff won't be as clear.
We will only apply the prettier formatting for failing tests in the diff
view so that diffs are cleaner and we don't pay for the additional
prettier calls when tests pass.
* Run test suite against both engines
* make eslint happy
* only run `stable` tests on Node 12
* use normal expectation instead of snapshot file
When we run the tests only against `stable` (for node 12), then the
snapshots exists for the `Oxide` build. They are marked as `obsolete`
and will cause the `npm run test` script to fail. Sadly.
Inlined them for now, but ideally we make those tests more blackbox-y so
that we test that we get source maps and that we can map the sourcemap
back to the input files (without looking at the actual annotations).
* properly indent inline css
