Compare Source

v0.19.0 — Go 1.24 floor, x/net v0.50.0, modernize clean-up

This release raises the minimum Go version to 1.24, refreshes CI
and build tooling around the newer toolchain, closes a batch of
line-coverage gaps, and rewords the testing docs so the TestCase
decision rule precedes the structural checklist.

Breaking

Change	Impact
Minimum Go raised from 1.23 to 1.24	Consumers on Go 1.23 must upgrade. go.mod now declares go 1.24.0.
CI matrix shifted to {1.24, 1.25, 1.26}	Drops 1.23 from the supported matrix.

Dependencies

Module	From	To
golang.org/x/net	v0.43.0	v0.50.0 (top of the band whose go.mod still declares go 1.24.0; v0.51.0+ requires Go 1.25).
golang.org/x/text	—	indirect follow-up to v0.34.0.

Tooling

• golangci-lint pinned per Go tier via get_version.sh:
  v2.8.0 on Go 1.24, v2.11.4 on Go 1.25+.
• revive pinned per tier: v1.14.0 / v1.15.0.
• modernize analyser enabled in .golangci.yml. Mechanical
  rewrites applied across the tree: counted for loops
  → range-over-int, benchmark loops → for b.Loop(),
  var counter int64 + atomic.AddInt64 → atomic.Int64,
  redundant generic type arguments dropped.
• actions/checkout@v6; explicit permissions: blocks on the
  build, test, race, codecov, and renovate workflows.
• fix_whitespace.sh parallelised and now strips UTF-8 BOMs.
• Switched from deprecated pnpx to pnpm dlx for Markdown tooling.

Tests

Targeted coverage additions for branches the existing suite missed:

• Nil-receiver paths (WrappedError.Error/Unwrap,
  CompoundError.OK, ErrGroup.Err on a pristine group).
• Non-first branches of type switches in Unwrap,
  CheckIsTemporary, CheckIsTimeout, and isSamePointer.
• Short-circuit and early-return paths in SliceEqual,
  SliceEqualFn, SliceUniquify, SliceReplaceFn.
• Parser fall-throughs in splitHostPortBracketed and
  SplitAddrPort.
• Panic paths in writeFormat (asserted by branch-specific
  substring), unknown-PC in frameForPC, and the skip-overflow
  branch of StackFrame.
• The IsZero() bool custom-interface branch, the typed-nil
  collapse branch of AsError, and the type-mismatch skip in
  ListForEach / ListForEachBackward.

No production code changes in the coverage commit — tests only.

Documentation

• TESTING.md reworded so the decision rule — ≥2 rows of
  shared-shape data feeding one assertion path — comes before
  the structural checklist, with two new DON'T entries
  (single-case TestCase, operation-under-test held in a struct
  field).
• AGENTS.md trades the bare "Table-driven tests are preferred."
  line for one that names the ≥2-row threshold and links to
  TESTING.md.
• British-English spelling swept through Markdown; stale go -C /
  Go-1.X-generics notes removed.

v0.18.4: : Testing Assertions and Documentation Improvements

Compare Source

This release enhances the testing infrastructure with new assertion functions, improves error assertion architecture, and corrects API documentation inaccuracies to match actual implementation.

Testing Enhancements

• New assertions: Added AssertNotContain and AssertMustNotContain for negative string containment testing
• Refactored error assertions: AssertError and AssertNoError are now independent base functions with domain-specific messaging rather than delegating to generic nil checks
• Improved error messages:
  • AssertError produces: "expected error, got nil" (failure) or "error: %v" (success)
  • AssertNoError produces: "unexpected error: %v" (failure) or "no error" (success)
• Enhanced coverage: Improved overall package coverage to 97.4%

Documentation Improvements

• Fixed 25+ function signatures in README.md to match actual implementation:
  • AddrPort(v) - was incorrectly documented as AddrPort(addr, port)
  • Zero[T](_ *T) - was incorrectly documented as Zero[T]()
  • All assertion functions now correctly show name... parameter (was documented as msg...)
  • IsError family signatures corrected by removing incorrect generic parameters
• Standardised naming: Renamed AGENT.md to AGENTS.md following project conventions
• Updated testing documentation: Refreshed architecture hierarchy in TESTING.md and TESTING_core.md

Dependencies

• Updated actions/setup-node to v6 in GitHub Actions workflows (#​146)

Backwards Compatibility

This release maintains complete backwards compatibility. All changes are either:

• Additions (new AssertNotContain/AssertMustNotContain functions)
• Internal refactoring (error assertion implementation details)
• Documentation corrections (no behaviour changes)

v0.18.3: : Enhanced Panic Testing and Build Improvements

Compare Source

Release v0.18.3

🎯 Highlights

This release enhances the AssertPanic testing utility with intelligent type-aware matching capabilities and includes significant build system improvements for better coverage collection and reporting.

✨ Features

Enhanced Panic Testing

• Type-aware panic validation: AssertPanic now provides different matching strategies based on the expected type.
  • nil: Accepts any panic (most common use case).
  • error: Uses errors.Is for error chain matching.
  • string: Performs substring matching for more resilient tests.
  • Recovered: Direct comparison without unwrapping.
  • Other types: Exact equality check with automatic Recovered unwrapping.
• Improved logging: Panic assertions now include clear context in their log messages.
• 100% test coverage: The entire testing.go file now has complete test coverage.

Build System Enhancements

• Enhanced coverage collection: New HTML and text report generation with .tmp/coverage/ directory structure.
• Improved Codecov integration: Better monorepo support with module-specific coverage targets.
• Go 1.25 support: Added as the default version in CI/CD pipelines.

🔧 Improvements

Development Experience

• Enhanced .editorconfig with comprehensive file type support.
• Improved .gitignore with additional patterns for better repository hygiene.
• Reorganised Makefile variable definitions for better maintainability.
• Updated GitHub Actions to latest versions (setup-go v6, setup-node v5).

Code Quality

• Refactored doAssertPanic helpers for cleaner implementation.
• Simplified panic validation logic by removing the report flag.
• Consistent use of the ok := test() pattern throughout.
• Field-aligned test structures for memory efficiency.

⚠️ Breaking Changes

• AssertPanic string matching: String expectations now use substring matching instead of exact equality.

  // Previously would fail, now passes:
  AssertPanic(t, func() { panic("unexpected error occurred") }, "error", "test")

• AssertPanic error matching: Error expectations now use errors.Is semantics for chain matching.

  // Now matches wrapped errors:
  AssertPanic(t, func() { panic(fmt.Errorf("wrapped: %w", io.EOF)) }, io.EOF, "test")

📊 Statistics

• Files changed: 16
• Insertions: 339 lines
• Deletions: 139 lines
• Test coverage: 97.3% overall, 100% for testing.go

v0.18.2

Compare Source

Release v0.18.2

This release introduces comprehensive same-ness testing utilities and significantly improves documentation patterns for the testing framework. The release focuses on enhancing the developer experience with better testing tools and clearer guidance on testing patterns.

🚀 New Features

Same-ness Testing Functions

• IsSame() - Base function for determining same-ness with comprehensive type handling
• AssertSame() / AssertNotSame() - Non-fatal assertion functions for same-ness testing
• AssertMustSame() / AssertMustNotSame() - Fatal assertion functions that terminate test execution on failure

Key Capabilities:

• Value types (numbers, strings, booleans): Same-ness means equal values.
• Reference types (slices, maps, pointers, channels, functions): Same-ness means pointer equality to the same underlying data structure.
• Proper nil handling: Typed nils of same type are considered same.
• Interface support: Recursive comparison of contained values.
• Special case handling: Zero-capacity slice optimisations, invalid reflect.Value protection.

Cross-Compatible Test Functions

• Enhanced MockT.Run documentation with interface compatibility patterns.
• doRun helper pattern for test functions that work with both *testing.T and MockT interfaces.
• Type assertion fallback mechanism for graceful degradation across different testing interfaces.

📚 Documentation Improvements

TESTING.md Enhancements

• Testing Patterns Overview clearly distinguishing TestCase interface vs t.Run() usage.
• "When to Use TestCase Interface" with specific criteria for table-driven tests.
• "When to Use t.Run() with Named Functions" for different test scenarios.
• Updated terminology consistency throughout documentation.
• British English corrections and improved formatting.

README.md Updates

• Same-ness testing functions documentation in the Testing Utilities section.
• Cross-Compatible Test Functions section with complete implementation examples.
• Fatal Assertion Functions section updated with new AssertMust variants.

🔧 Code Quality Improvements

Test Suite Modernization

• Refactored existing tests to use modern assertion patterns:
  • as_test.go: Updated to use AssertEqual for length checks
  • compounderror_test.go: Modernized with AssertSame, AssertEqual, AssertNotNil
  • errgroup_test.go: Improved with AssertSame for error instance checks
  • lists_test.go: Enhanced with AssertNotSame for independence verification
• Consistent test case patterns applied across zero_test.go functions.
• Fatal assertion pattern applied consistently for critical preconditions.

Enhanced Test Coverage

• Comprehensive test suite for same-ness functions covering all scenarios.
• MockT.Run() testing for both success and failure scenarios.
• Coverage maintained at 97.3% with all tests passing.

🛠️ Dependencies & Infrastructure

• golang.org/x/net updated to v0.43.0.
• actions/checkout updated to v5 across all GitHub workflows.

Build System

• Updated CSpell dictionary with new technical terms.
• Enhanced GitHub Actions workflows with latest action versions.

🔍 Technical Details

Implementation Highlights

• asReflectValue() helper to avoid duplicate reflect.ValueOf() calls.
• isReflectValueSame() helper following established naming patterns.
• Special handling for empty slices due to Go runtime memory optimisation.
• Stack overflow protection in recursive interface comparisons.
• Unsafe pointer and complex number support with comprehensive tests.

Breaking Changes

None - This is a purely additive release that maintains full backward compatibility.

📊 Statistics

• 18 files changed: 1,323 insertions, 257 deletions.
• 4 major features added to the testing utilities.
• 5 GitHub workflow files updated with latest dependencies.
• 2 comprehensive documentation overhauls (TESTING.md, README.md).
• 150+ new test cases added for comprehensive coverage.

🎯 Impact

This release significantly enhances the testing experience for both internal development and external library users by:

1. Providing powerful same-ness testing utilities that properly distinguish between value and reference equality.
