This is based on spv.paramMemory.frag.out which exercises the writeonly storage image case. This appears to need desktop GLSL. The generated SPIR-V fails validation because the image_write function takes a parameter which is pointer to an OpTypeImage with Unknown format. But the parameters passed in are pointer to OpTypeImage with formats Rgba32f and Rgba16f. The validator rejects this, saying the parameter types must match.
Glslang Tests based on the Google Test Framework
This directory contains Google Test based test fixture and test cases for glslang.
Apart from typical unit tests, necessary utility methods are added into
the GlslangTests fixture to provide the ability to do
file-based integration tests. Various *.FromFile.cpp files lists names
of files containing input shader code in the Test/ directory. Utility
methods will load the input shader source, compile them, and compare with
the corresponding expected output in the Test/baseResults/ directory.
How to run the tests
Please make sure you have a copy of Google Test checked out under
the External directory before building. After building, just run the
ctest command or the gtests/glslangtests binary in your build directory.
The gtests/glslangtests binary also provides an --update-mode command
line option, which, if supplied, will overwrite the golden files under
the Test/baseResults/ directory with real output from that invocation.
This serves as an easy way to update golden files.
