Test Coverage Assessment for PR #28

Summary

This PR consolidates version packages from tools/cfl/internal/version and tools/jtk/internal/version into a shared shared/version package. The changes are primarily:

1. New code: shared/version/version.go (30 lines) - 3 exported variables and 2 helper functions
2. Deleted code: Two tool-specific version packages (9 + 18 lines)
3. Updated imports: Both root.go files updated to use the shared package
4. Build config changes: Makefiles, GoReleaser, and Snapcraft configs updated with new ldflags paths

Test Coverage Analysis

Current State: The new shared/version/version.go has no test file (go test ./shared/version/... reports "no test files").

Is this acceptable? Yes, for the following reasons:

1. Trivial code: The package contains only:

   • 3 string variables with default values
   • Info() - returns Version (1 line)
   • Full() - string concatenation (1 line)

2. Build-time validation: The ldflags injection is validated through:

   • Successful builds (CI verifies this)
   • The PR notes "Version output verified for both tools"

3. No business logic: No conditionals, no error handling, no edge cases to test

4. Pattern consistency: Looking at the deleted files, neither tools/cfl/internal/version/version.go nor tools/jtk/internal/version/version.go had tests either - the jtk version had the same Info() and Full() functions that are now being consolidated

5. Integration coverage: The root.go integration points use the version package, and those root commands are exercised by other tests

Potential Improvements (Optional)

If the team wants to enforce test coverage for all shared packages, a simple test would look like:

func TestInfo(t *testing.T) {
    // Default value when not built with ldflags
    if got := Info(); got != "dev" {
        t.Errorf("Info() = %q, want %q", got, "dev")
    }
}

func TestFull(t *testing.T) {
    got := Full()
    if !strings.Contains(got, "dev") {
        t.Error("Full() should contain version")
    }
    if !strings.Contains(got, "built") {
        t.Error("Full() should contain 'built'")
    }
}

However, this provides minimal value since it only tests string concatenation with default values.

Verdict

No test coverage gaps that would warrant blocking this PR. The code is trivial, follows existing patterns (the deleted code also had no tests), and the real validation happens at build time through ldflags injection.

The PR correctly updates all ldflags references, standardizes the variable name (Date -> BuildDate), and adds two convenience functions that existed in jtk but not cfl.
