Description
Fixes #168.
This fix modifies the engine fixture in tests/api_test.py to use the pytest
yieldpattern. By moving the cleanup logic(api.off() and api.disable())into the fixture's teardown phase, we guarantee that the global state is reset after every test, even if a test fails or crashes. This eliminates the "polluter" behavior where a single assertion failure causes cascading failures in subsequent tests.It fixes the following tests:
test_activate(),test_on(),test_use(), andtest_mock_contructors().PR Checklist
