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][gtest] 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. + +[gtest]: https://github.com/google/googletest |
