From cb482a7fe6207db78a0ceb963f29a92940dffd9b Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 2 Feb 2026 01:17:38 +0000 Subject: [PATCH] feat: Add test audit report This commit introduces a comprehensive test audit report for the Enchantrix project. The report, `AUDIT-TESTING.md`, provides a detailed analysis of the current state of testing, including: - **Coverage Analysis:** A breakdown of line and branch coverage, highlighting untested code paths. - **Test Quality:** An evaluation of test independence, clarity, and reliability. - **Missing Tests:** Identification of gaps in edge case, error path, and performance testing. - **Anti-Patterns:** A review of common anti-patterns found in the test suite. - **Suggested Tests:** A list of actionable recommendations for improving test coverage and quality. This audit serves as a baseline for future improvements to the project's test suite and overall code quality.

Coverage Analysis + +The overall test coverage for the project is **76.0%**. While the core `pkg` libraries are well-tested (most above 90%), the `cmd` and `examples` packages have significant gaps, bringing down the total average. + +### Line Coverage + +- **Total Coverage:** 76.0% +- **`cmd/trix`:** ~80% +- **`pkg/crypt`:** ~95% +- **`pkg/enchantrix`:** ~97% +- **`pkg/trix`:** ~97% +- **`examples/*`:** 0% + +### Branch Coverage + +Branch coverage was not explicitly measured, but the line coverage analysis revealed several untested branches in the codebase. These are detailed in the "Untested Code" section below. + +### Untested Code + +The following files and functions have low or zero test coverage: + +- **`cmd/trix/main.go`:** + - `handleSigil`: Error handling for `ioutil.ReadFile` is not tested. + - `handleHash`: Error handling for `ioutil.ReadFile` is not tested. + - `handleEncode`: Error handling for `ioutil.ReadFile` and `ioutil.WriteFile` is not tested. + - `handleDecode`: Error handling for `ioutil.ReadFile` and `ioutil.WriteFile` is not tested. +- **`pkg/crypt/crypt.go`:** + - `ensurePGP`: The branch where `s.pgp` is not nil is not tested. +- **`pkg/crypt/std/rsa/rsa.go`:** + - `GenerateKeyPair`: The error path for `x509.MarshalPKIXPublicKey` is not tested. +- **`pkg/enchantrix/crypto_sigil.go`:** + - `NewChaChaPolySigilWithObfuscator`: The error path is not tested. + - `In`: The error path for `chacha20poly1305.NewX` is not tested. + - `Out`: The error path for `chacha20poly1305.NewX` is not tested. +- **`pkg/enchantrix/sigils.go`:** + - `HexSigil.Out`: The error path for `hex.Decode` is not tested. + - `Base64Sigil.Out`: The error path for `base64.StdEncoding.Decode` is not tested. +- **`pkg/trix/crypto.go`:** + - `EncryptPayload`: The error paths for `enchantrix.NewChaChaPolySigilWithObfuscator` and `sigil.In` are not tested. + - `DecryptPayload`: The error path for `enchantrix.NewChaChaPolySigilWithObfuscator` is not tested. +- **`pkg/trix/trix.go`:** + - `Unpack`: The branch where `OutSigils` is empty and it falls back to `InSigils` is not tested. +- **All `main.go` files in `examples/` subdirectories have 0% coverage.** + +## 2. Test Quality + +The overall quality of the tests is high. The project consistently uses the `testify` library for assertions and follows a clear `Good, Bad, Ugly` structure for tests. + +### Test Independence + +- Tests are mostly isolated. However, some tests in `cmd/trix/main_test.go` and `pkg/crypt/crypt_test.go` use global variables, which is an anti-pattern that can lead to test interdependencies. + +### Test Clarity + +- **Descriptive Names:** Most test names are clear and descriptive. Some could be improved, for example, `TestMain_Good` in `cmd/trix/main_test.go` could be renamed to `TestMain_NoArgs_PrintsHelp` to be more specific. +- **Arrange-Act-Assert:** The Arrange-Act-Assert pattern is generally followed, but could be more consistently applied. + +### Test Reliability + +- **Flaky Tests:** No flaky tests were observed during the audit. +- **External Dependencies:** External dependencies are well-mocked, particularly in `pkg/crypt/std/rsa/rsa_test.go` and `pkg/enchantrix/crypto_sigil_test.go`. + +## 3. Missing Tests + +- **Edge Cases:** The tests cover a good range of edge cases, but some are missing, such as the fallback logic in `pkg/trix/trix.go:Unpack`. +- **Error Paths:** The primary gap in testing is the lack of coverage for I/O error paths in `cmd/trix/main.go` and other error paths as detailed in the "Untested Code" section. +- **Integration Tests:** The `TestEncryptedTrixRoundTrip` test in `pkg/trix/crypto_test.go` is a good example of an integration test. More integration tests could be added to cover the interaction between the `trix` CLI and the `pkg` libraries. +- **Performance Tests:** There are no performance tests (e.g., load, stress) in the project. While not critical for a library of this nature, benchmark tests for the cryptographic functions could be beneficial. + +## 4. Anti-Patterns + +- **Shared State:** The use of global variables for the `service` in `pkg/crypt/crypt_test.go` and for `rootCmd`, `exit`, etc. in `cmd/trix/main_test.go` is an anti-pattern. This can lead to test interdependencies and flaky tests. + +## 5. Suggested Tests to Add + +Based on this audit, the following tests should be added to improve coverage and quality: + +1. **`cmd/trix/main_test.go`:** + - Add tests for `handleSigil`, `handleHash`, `handleEncode`, and `handleDecode` that simulate file I/O errors. +2. **`pkg/crypt/crypt_internal_test.go`:** + - Add a test case to cover the `s.pgp != nil` branch of `ensurePGP`. +3. **`pkg/crypt/std/rsa/rsa_internal_test.go`:** + - Add a test case to cover the error path for `x509.MarshalPKIXPublicKey` in `GenerateKeyPair`. +4. **`pkg/enchantrix/crypto_sigil_internal_test.go`:** + - Add a test case to cover the error path in `NewChaChaPolySigilWithObfuscator`. + - Add test cases to cover the error path for `chacha20poly1305.NewX` in `In` and `Out`. +5. **`pkg/enchantrix/sigils_internal_test.go`:** + - Add a test case for `HexSigil.Out` with invalid hex data. + - Add a test case for `Base64Sigil.Out` with invalid base64 data. +6. **`pkg/trix/crypto_internal_test.go`:** + - Add test cases to cover the error paths in `EncryptPayload` and `DecryptPayload`. +7. **`pkg/trix/trix_internal_test.go`:** + - Add a test case for `Unpack` where `OutSigils` is empty. +8. **`examples/examples_test.go`:** + - Add tests for the `main` functions in the `examples` subdirectories.
