SPIRV-Cross maintains a test suite of shaders with reference output of how the output looks after going through a roundtrip through
glslangValidator then back through SPIRV-Cross again. The reference files are stored inside the repository in order to be able to track regressions.
All pull requests should ensure that test output does not change unexpectedly. This can be tested with `./test_shaders.py shaders`.
However, when improving SPIRV-Cross there are of course legitimate cases where reference output should change.
In these cases, run `./test_shaders.py shaders --update` to update the reference files and include these changes as part of the pull request.
Always make sure you are running up to date glslangValidator as well as SPIRV-Tools when updating reference files.
All pull requests should ensure that test output does not change unexpectedly. This can be tested with:
In short, the master branch should always be able to run `./test_shaders.py shaders` without failure.
```
./test_shaders.py shaders
./test_shaders.py shaders --opt
./test_shaders.py shaders-hlsl --hlsl
./test_shaders.py shaders-hlsl --hlsl --opt
./test_shaders.py shaders-msl --msl
./test_shaders.py shaders-msl --msl --opt
```
although there are a couple of convenience script for doing this:
```
./checkout_glslang_spirv_tools.sh # Checks out glslang and SPIRV-Tools at a fixed revision which matches the reference output.
./test_shaders.sh # Runs over all changes and makes sure that there are no deltas compared to reference files.
```
However, when improving SPIRV-Cross there are of course legitimate cases where reference output should change.
In these cases, run:
```
./update_test_shaders.sh
```
to update the reference files and include these changes as part of the pull request.
Always make sure you are running the correct version of glslangValidator as well as SPIRV-Tools when updating reference files.
See `checkout_glslang_spirv_tools.sh`.
In short, the master branch should always be able to run `./test_shaders.py shaders` and friends without failure.
SPIRV-Cross uses Travis CI to test all pull requests, so it is not strictly needed to perform testing yourself if you have problems running it locally.
A pull request which does not pass testing on Travis will not be accepted however.
