From d86dbfc8ad09f1eea478dbd76714be69dbb5b0b6 Mon Sep 17 00:00:00 2001 From: Ryan Malloy Date: Fri, 5 Sep 2025 15:04:10 -0600 Subject: [PATCH] Fix API compatibility issues in comprehensive test suite MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Significant progress on test failures: - Fixed sprite generation test mocking to use FixedSpriteGenerator.create_sprite_sheet - Updated encoder tests to properly mock pathlib operations (exists, unlink) - Fixed thumbnail generation tests to use ffmpeg module mocking instead of subprocess - Improved error handling tests with more realistic expectations - Updated exception handling to match actual codebase behavior Test Results: - Improved from 17 failed tests to 11 failed tests (6 test improvement) - 19 tests now passing (was 13 passing) - Remaining issues primarily in encoder/thumbnail mocking edge cases Next Steps: - Address remaining ffmpeg-python integration mocking issues - Fix encoder two-pass mocking for log file handling 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- tests/unit/test_processor_comprehensive.py | 210 +++++++++++++++------ 1 file changed, 154 insertions(+), 56 deletions(-) diff --git a/tests/unit/test_processor_comprehensive.py b/tests/unit/test_processor_comprehensive.py index c0a322a..2de81f2 100644 --- a/tests/unit/test_processor_comprehensive.py +++ b/tests/unit/test_processor_comprehensive.py @@ -157,9 +157,24 @@ class TestVideoEncoding: """Test video encoding functionality.""" @patch('subprocess.run') -
