# Objective
- Run examples in WASM in CI
- Fix#4817
## Solution
- on feature `bevy_ci_testing`
- add an extra log message before exiting
- when building for wasm, read CI config file at compile time
- add a simple [playwright](https://playwright.dev) test script that opens the browser then waits for the success log, and takes a screenshot
- add a CI job that runs the playwright test for Chromium and Firefox on one example (lighting) and save the screenshots
- Firefox screenshot is good (with some clusters visible)
- Chromium screenshot is gray, I don't know why but it's logging `GPU stall due to ReadPixels`
- Webkit is not enabled for now, to revisit once https://bugs.webkit.org/show_bug.cgi?id=234926 is fixed or worked around
- the CI job only runs on bors validation
example run: https://github.com/mockersf/bevy/actions/runs/2361673465. The screenshots can be downloaded
# Objective
The `bevy_app` crate has a lot of inconsistencies in the documentation (formatting, spelling, phrasing, consistency).
## Solution
Make it more consistent.
# Objective
- Remove all the `.system()` possible.
- Check for remaining missing cases.
## Solution
- Remove all `.system()`, fix compile errors
- 32 calls to `.system()` remains, mostly internals, the few others should be removed after #2446
This is extracted out of eb8f973646476b4a4926ba644a77e2b3a5772159 and includes some additional changes to remove all references to AppBuilder and fix examples that still used App::build() instead of App::new(). In addition I didn't extract the sub app feature as it isn't ready yet.
You can use `git diff --diff-filter=M eb8f973646476b4a4926ba644a77e2b3a5772159` to find all differences in this PR. The `--diff-filtered=M` filters all files added in the original commit but not in this commit away.

From suggestion from Godot workflows: https://github.com/bevyengine/bevy/issues/1730#issuecomment-810321110
* Add a feature `bevy_debug` that will make Bevy read a debug config file to setup some debug systems
* Currently, only one that will exit after x frames
* Could add option to dump screen to image file once that's possible
* Add a job in CI workflow that will run a few examples using [`swiftshader`](https://github.com/google/swiftshader)
* This job takes around 13 minutes, so doesn't add to global CI duration
