Description

At the moment we only have last-frames tests. Although they are useful, it's not enough. We would need to have tests for cli flags, that check videos, etc. This issue will keep a list of tests that need to be added. Please make more suggestions for tests!

Tests that need to be added

  • We should have at least one test for each CLI flag.
  • We should test that the cascading priorities in the config system work as expected. Ties in with #201
  • We should create a test to certify a clean install. See #11.
  • Testing video content
  • Test that manim runs correctly on all environments/prompts/versions #336
  • Regression test for #240
  • Test z-order stuff #327
  • Test to ensure MovingCamera and ZoomedScene let the camera move as they should. From #388 .
  • Test the functionality of asking the user for which scenes to render #523
  • There are no tests for the -s flag or the -t flag
  • Test for add_fixed_in_frame_mobjects which is used in 3D scenes #569, currently broken
  • Tests for SVG images
  • @XorUnison Once video tests are implemented reverse_direction should get one
  • @XorUnison Test for Brace
  • @PhilippImhof Graphical unit test for Text and MarkupText using a fixed font (TTF)

Research direction
This issue tracks multiple test tasks. Start by reading the project's test directory to understand the existing test structure (e.g., last frames tests). Choose one unchecked checkbox, such as 'test each CLI flag' or 'regression test for #240'. Create a test that verifies the expected behavior. Refer to the linked issues for context. Run tests with pytest and ensure they pass. If stuck, comment on the issue for guidance.
