…hmark cases for CI performance
WalkthroughThe test suite for ASCII string case conversion functions was refactored to separate correctness and performance test cases. A new test was added to explicitly cover all ASCII characters, while some HTTP-related test cases were moved from correctness tests to benchmarks. One non-ASCII test was removed, with its cases merged elsewhere. Changes

Summary of Changes
Hello @sixcolors, 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 refactors the test suite for the ToUpper and ToLower ASCII string conversion functions. The primary objective is to enhance the clarity and organization of the test cases while simultaneously optimizing the performance of benchmark executions by streamlining the set of inputs used for benchmarking, which should contribute to faster continuous integration cycles.
Highlights
- Test Case Reorganization: The test cases for ASCII string conversions have been reorganized for improved clarity and maintainability. Many specific HTTP method, header, and URL test cases were removed from the main
testCasesvariable. - Benchmark Optimization: A new
benchmarkCasesvariable has been introduced, containing a reduced and more focused set of test cases specifically for performance benchmarking. This change aims to optimize CI performance by speeding up benchmark runs. - Enhanced Test Formatting: The
Test_ASCII_EdgeCasesfunction now uses a more descriptive naming format (ASCII-char-%03d) for its subtests, improving readability of test output. - Consolidated Non-ASCII Tests: The dedicated
Test_NonASCII_Unchangedfunction has been removed, as its functionality for testing non-ASCII character handling is now integrated directly into the maintestCasesvariable.

117-133: Excellent comprehensive ASCII character coverage.The new test systematically validates all ASCII characters (0-127) against the standard library implementation, ensuring complete correctness. The loop variable capture is correctly handled with
idx := ito avoid closure issues in parallel tests.One minor suggestion for improved readability:
- idx := i - c := byte(idx) - t.Run(fmt.Sprintf("ASCII-char-%03d", idx), func(t *testing.T) { + char := byte(i) + t.Run(fmt.Sprintf("ASCII-char-%03d", i), func(t *testing.T) { t.Parallel() - s := string(c) + s := string(char) upperExpected := strings.ToUpper(s) lowerExpected := strings.ToLower(s) - require.Equal(t, upperExpected, ToUpper(s), "ToUpper failed for ASCII-char-%03d", idx) - require.Equal(t, lowerExpected, ToLower(s), "ToLower failed for ASCII-char-%03d", idx) + require.Equal(t, upperExpected, ToUpper(s), "ToUpper failed for ASCII-char-%03d", i) + require.Equal(t, lowerExpected, ToLower(s), "ToLower failed for ASCII-char-%03d", i) })

Learning: In the Fiber framework tests, using `ctx.Response.Header.Cookie` may not be suitable for parsing cookies from the response header, as it requires a `*Cookie` and fills it rather than returning a string value; thus, manual parsing of the `Set-Cookie` header may be necessary.

5-6: LGTM! Excellent documentation addition.The package comments clearly explain the purpose and scope of the test suite, which improves code maintainability and understanding.
28-44: Well-structured test case reorganization.The separation of correctness tests from performance benchmarks is a good design decision. The testCases now focus on essential edge cases and correctness validation with clear, representative examples including ASCII letters and non-ASCII character handling.
46-79: Good separation of benchmark test cases.The dedicated benchmarkCases slice appropriately contains performance-focused test cases including HTTP methods, headers, URLs, and various string sizes. This separation allows for optimized CI performance while maintaining comprehensive performance testing.
136-136: Correct benchmark function updates.All benchmark functions properly reference the new
benchmarkCasesslice, maintaining consistency with the test reorganization while preserving performance testing capabilities.Also applies to: 151-151, 166-166, 181-181
Reorganize and improve test cases for ASCII character conversions, enhance output formatting, and reduce benchmark cases to optimize CI performance.
