picogl.tests.test_object_renderer

Unit tests for the ObjectRenderer 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.object.ObjectRenderer class, which provides unified rendering for textured and untextured objects.

The tests cover:

• Object initialization with various parameters

• Shader initialization and compilation

• VAO and VBO setup for different data types

• Rendering pipeline and drawing operations

• Texture loading and binding

• 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.object.ObjectRenderer

• picogl.renderer.meshdata.MeshData

To run the tests:

python -m unittest picogl.tests.test_object_renderer
