From c2a327695ba1603d1d4cdef8c3b204181926d948 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 5 Nov 2025 01:02:12 +0000 Subject: [PATCH] Improve test suite quality and coverage This commit enhances the test suite with multiple improvements: High Priority Fixes: - Fixed weak assertions in configuration_tests.rs (lines 305-311, 416-434) - Added proper state verification with detailed error messages - Improved test assertions to check for specific success/failure conditions - Added validation that disabled and invalid deployments are properly filtered New Test Coverage: - Added tests for custom branch configuration (observe_branch annotation) - Added tests for short/long tag type handling and defaults - Added tests for registry configuration (URL, secret name, namespace) - Added tests to verify default values (master branch, long tag type) - Added test for invalid tag type defaulting to long Code Quality Improvements: - Created shared test fixtures module (tests/common/mod.rs) - minimal_valid_annotations() helper - complete_valid_annotations() helper - create_test_deployment() helper - dummy_ssh_key() constant - Added comprehensive documentation to all test functions - Documented git_tests.rs test cases - Documented files_tests.rs test cases - Documented configuration_tests.rs test cases Benefits: - Reduces code duplication across test files - Improves test reliability with stronger assertions - Better test documentation for maintainability - Increased test coverage for edge cases and default values - More descriptive failure messages for easier debugging Related to test analysis and improvement recommendations. --- tests/common/mod.rs | 99 ++++++++++ tests/configuration_tests.rs | 348 +++++++++++++++++++++++++++++++---- tests/files_tests.rs | 6 + tests/git_tests.rs | 6 + 4 files changed, 428 insertions(+), 31 deletions(-) create mode 100644 tests/common/mod.rs diff --git a/tests/common/mod.rs b/tests/common/mod.rs new file mode 100644 index 0000000..fc80690 --- /dev/null +++ b/tests/common/mod.rs @@ -0,0 +1,99 @@ +/// Shared test fixtures and utilities for test modules +pub mod fixtures { + use k8s_openapi::api::apps::v1::{Deployment, DeploymentSpec};
