From: Mikko Rasa Date: Tue, 16 Mar 2021 18:04:30 +0000 (+0200) Subject: Refactor the GLSL compiler test cases with a helper class X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=1e3605edd174bce94bb21b662c7a83f79f1df37f;p=libs%2Fgl.git Refactor the GLSL compiler test cases with a helper class I'm not super pleased with the virtual fail function in the helper, but no better ideas came to mind so it can be like that for now. --- diff --git a/tests/glsl/glslcompiler.cpp b/tests/glsl/glslcompiler.cpp index 30805db3..0fd08554 100644 --- a/tests/glsl/glslcompiler.cpp +++ b/tests/glsl/glslcompiler.cpp @@ -7,11 +7,9 @@ #include #include -#include - -class GlslCompilerTest: public Msp::Test::RegisteredTest +class GlslCompilerHelper { -private: +protected: struct TestCase { std::string name;
