[CI] Investigate graphics unit testing under macOS #21
Description
After having tried many different things, launching unit tests which require graphics capabilities (using GLFW in this case) always fail. It is yet unknown if this is due to:
- A technical issue of macOS VMs/servers without any available workaround (which doesn't seem like it, since there are reports that it can be done, at least could have been some time ago);
- Something missing concerning the window's initialization: GLFW may need specific settings to be able to start under those conditions;
- Specific arguments to launch Xvfb and/or the tests executable with.
See:
Note: Xvfb needs the package xquartz to be installed by brew.
