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.
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.
