Backend Tests

This directory (/test/backend) contains scripts to run Filament's backend tests using a software rasterizer (Mesa). This is useful for running tests in a continuous integration environment where a GPU might not be available.

The test.sh script will:

1. Build Mesa if needed.
2. Build the backend tests.
3. Run the tests using the OpenGL and Vulkan backends with Mesa.

Flags

The test.sh script accepts the following flags:

• --gtest_filter: Filters the tests that are run. This is passed directly to the underlying gtest executable.
• --backend: Specifies which backend to test. Can be opengl, vulkan, or a comma-separated list (e.g., opengl,vulkan). Defaults to both.
