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.
