True, good point. In any case, as the test lacks a [test] section, full shader.py runs would just check if the test links (assuming that ARB_gl_spirv are available). Having said so ... > > The file extension is also confusing. Maybe we should name these type > of files .shader_source or something similar rather than .shader_test ??? ... this makes sense. That name fits better, and would avoid the previous issue. As that would be a small change, I will make the change locally, while I wait for the review of the other patches.
