Summary of Changes

Hello @wk989898, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the project's test suite by adding a substantial volume of new unit tests and improving existing ones. The changes aim to bolster the stability and correctness of critical components by covering more edge cases, validating configurations rigorously, and ensuring proper behavior under various conditions. The integration of goleak further strengthens the project's ability to identify and manage goroutine leaks, contributing to overall system health and reliability.

Highlights

  • Expanded Unit Test Coverage: Introduced a large number of new unit tests across various packages including API clients, configuration, error handling, etcd interactions, data filtering, orchestration, sink codecs, data structures, garbage collection, and upstream management.
  • Improved Goroutine Leak Detection: Integrated go.uber.org/goleak into TestMain functions in multiple packages to enhance the detection of goroutine leaks during testing, with specific ignorable functions configured.
  • Refined Test Logic: Updated existing test logic for better determinism, such as using time.UTC for timestamp conversions and simplifying default value assertions in pkg/common/event/mounter_test.go.
  • Comprehensive Configuration Validation Tests: Added extensive tests for configuration validation and adjustment across ServerConfig, DBConfig, KVClientConfig, SchedulerConfig, MessagesConfig, LargeMessageHandle, and SinkConfig.
  • Etcd Client and Orchestrator Robustness Tests: Included detailed tests for etcd client retry mechanisms, lease management, watch channel behavior, and orchestrator state linearizability, batching, and snapshot isolation during concurrent operations.
  • Sink Codec and URI Utility Tests: Added thorough tests for various sink codecs (Canal, Open Protocol, Simple) covering encoding/decoding, message size limits, batching, and callback handling. Also, new tests for URI parsing, IPv6 validation, and sensitive data masking.
  • Performance Benchmarks: Introduced benchmarks for expression filters (pkg/filter/expr_filter_bench_test.go) and map implementations (pkg/spanz/map_bench_test.go) to evaluate and compare performance characteristics.

Code Review

This pull request introduces a significant number of unit tests across various packages, which greatly enhances the project's test coverage and robustness. The new tests are well-structured and cover many important scenarios, including concurrency and edge cases. Additionally, the PR improves the testing infrastructure by setting up leak detection in several packages. I've found one test case that appears to be testing Go's standard library functions instead of project-specific code, which I've left a comment on. Overall, this is a valuable contribution to improving the project's quality.

The test TestDecodePassword appears to test the behavior of Go's standard library functions (url.QueryEscape, url.QueryUnescape, base64.StdEncoding.EncodeToString, base64.StdEncoding.DecodeString) rather than any specific function from this package. It doesn't seem to call a decodePassword function from the project. As it stands, this test adds little value by testing standard library behavior and could be confusing. If it's intended to test a specific function, that function should be called within the test. Otherwise, it might be better to remove this test to avoid confusion.
