picogl.tests.test_object_renderer
=================================

.. py:module:: picogl.tests.test_object_renderer

.. autoapi-nested-parse::

   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 :class:`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
