export const description = `
This tests entry point validation of compute/render pipelines and their shader modules.
The entryPoint in shader module include standard "main" and others.
The entryPoint assigned in descriptor include:
- Matching case (control case)
- Empty string
- Mistyping
- Containing invalid char, including space and control codes (Null character)
- Unicode entrypoints and their ASCIIfied version
TODO:
- Test unicode normalization (gpuweb/gpuweb#1160)
- Fine-tune test cases to reduce number by removing trivially similiar cases
