1 Glslang Tests based on the Google Test Framework 2 ================================================ 3 4 This directory contains [Google Test][gtest] based test fixture and test 5 cases for glslang. 6 7 Apart from typical unit tests, necessary utility methods are added into 8 the [`GlslangTests`](TestFixture.h) fixture to provide the ability to do 9 file-based integration tests. Various `*.FromFile.cpp` files lists names 10 of files containing input shader code in the `Test/` directory. Utility 11 methods will load the input shader source, compile them, and compare with 12 the corresponding expected output in the `Test/baseResults/` directory. 13 14 How to run the tests 15 -------------------- 16 17 Please make sure you have a copy of [Google Test][gtest] checked out under 18 the `External` directory before building. After building, just run the 19 `ctest` command or the `gtests/glslangtests` binary in your build directory. 20 21 The `gtests/glslangtests` binary also provides an `--update-mode` command 22 line option, which, if supplied, will overwrite the golden files under 23 the `Test/baseResults/` directory with real output from that invocation. 24 This serves as an easy way to update golden files. 25 26 [gtest]: https://github.com/google/googletest 27
