picogl.tests.test_texture_renderer

Unit tests for the TextureRenderer class in the PicoGL OpenGL backend.

This module contains a comprehensive suite of unit tests for verifying the correctness, robustness, and interface of the picogl.renderer.texture.TextureRenderer class, which provides specialized texture rendering functionality.

The tests cover:

• Object initialization and inheritance from ObjectRenderer

• Texture initialization and loading

• Path management and resolution

• UV coordinate handling and inversion

• Error handling and edge cases

• Data validation and type conversion

Dependencies:

• unittest (standard library)

• unittest.mock.MagicMock for OpenGL function mocking

• numpy for test data

• picogl.renderer.texture.TextureRenderer

• picogl.renderer.meshdata.MeshData

To run the tests:

python -m unittest picogl.tests.test_texture_renderer
