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
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.
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.
