# Objective
- Improve CI when testing rendering by having smarter testbeds
## Solution
- CI testing no longer need a config file and will run with a default
config if not found
- It is now possible to give a name to a screenshot instead of just a
frame number
- 2d and 3d testbeds are now driven from code
- a new system in testbed will watch for state changed
- on state changed, trigger a screenshot 100 frames after (so that the
scene has time to render) with the name of the scene
- when the screenshot is taken (`Captured` component has been removed),
switch scene
- this means less setup to run a testbed (no need for a config file),
screenshots have better names, and it's faster as we don't wait 100
frames for the screenshot to be taken
## Testing
- `cargo run --example testbed_2d --features bevy_ci_testing`
# Objective
- Progress towards #15918
- Add tests for 3d
## Solution
- Add tests that cover lights, bloom, gltf and animation
- Removed examples `contributors` and `load_gltf` as they don't
contribute additional checks to CI
## Testing
- `CI_TESTING_CONFIG=.github/example-run/testbed_3d.ron cargo run
--example testbed_3d --features "bevy_ci_testing"`
