Function TestSpec_Variables_ErrNotGitRepository

pkg/gitutil/spec_test.go:349–361

TestSpec_Variables_ErrNotGitRepository validates the documented sentinel-error contract for ErrNotGitRepository. Specification (Variables + Behavioral contracts): - ErrNotGitRepository is the sentinel error returned by FindGitRoot and FindGitRootFrom when no .git entry is found while traversing up

(t *testing.T)

// The README usage example relies on errors.Is(err, gitutil.ErrNotGitRepository),
// so the returned error must satisfy that comparison.
func TestSpec_Variables_ErrNotGitRepository(t *testing.T) {
	require.Error(t, gitutil.ErrNotGitRepository,
		"ErrNotGitRepository should be a non-nil sentinel error value")

	// A directory created outside any git repository should surface the
	// documented sentinel error.
	isolated := t.TempDir()
	_, err := gitutil.FindGitRootFrom(isolated)
	require.Error(t, err,
		"FindGitRootFrom should error when startDir is not inside a git repository")
	assert.ErrorIs(t, err, gitutil.ErrNotGitRepository,
		"FindGitRootFrom should return the documented ErrNotGitRepository sentinel")
}

// TestSpec_PublicAPI_ReadFileFromHEAD validates the documented behavior of
// ReadFileFromHEAD as described in the package README.md.
