| Glslang Tests based on the Google Test Framework |
| ================================================ |
| |
| This directory contains [Google Test][gtest] based test fixture and test |
| cases for glslang. |
| |
| Apart from typical unit tests, necessary utility methods are added into |
| the [`GlslangTests`](TestFixture.h) 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][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. |
