Function TestFindLocalCheatpathSymlinkInAncestor

internal/config/config_test.go:179–210

TestFindLocalCheatpathSymlinkInAncestor tests discovery through a symlinked ancestor directory. When the cwd is reached via a symlink, filepath.Dir walks the symlinked path (not the real path), so .cheat must be findable through that chain.

(t *testing.T)

// walks the symlinked path (not the real path), so .cheat must be findable
// through that chain.
func TestFindLocalCheatpathSymlinkInAncestor(t *testing.T) {
	tempDir := t.TempDir()

	// Create real/project/.cheat
	realProject := filepath.Join(tempDir, "real", "project")
	if err := os.MkdirAll(realProject, 0755); err != nil {
		t.Fatalf("failed to create real project dir: %v", err)
	}
	if err := os.Mkdir(filepath.Join(realProject, ".cheat"), 0755); err != nil {
		t.Fatalf("failed to create .cheat dir: %v", err)
	}

	// Create symlink: linked -> real/project
	linkedProject := filepath.Join(tempDir, "linked")
	if err := os.Symlink(realProject, linkedProject); err != nil {
		t.Fatalf("failed to create symlink: %v", err)
	}

	// Create sub inside the symlinked path
	subDir := filepath.Join(linkedProject, "sub")
	if err := os.Mkdir(subDir, 0755); err != nil {
		t.Fatalf("failed to create sub dir: %v", err)
	}

	// Search from linked/sub — should find linked/.cheat
	// (os.Stat follows symlinks, so linked/.cheat resolves to real/project/.cheat)
	result := findLocalCheatpath(subDir)
	expected := filepath.Join(linkedProject, ".cheat")
	if result != expected {
		t.Errorf("expected %s, got %s", expected, result)
	}
}

// TestFindLocalCheatpathPermissionDenied tests that unreadable ancestor
// directories are skipped and the walk continues upward.
