Function TestMain

internal/app/background_test.go:22–36

TestMain defaults claude.BGCommandRunner to an empty background-agent registry for the whole app test package. Without this, every show / list / do over a session-bound task would spawn a real `claude agents --json` subprocess (slow + non-hermetic). Tests that exercise bg behavior override it via st

(m *testing.M)

// exercise bg behavior override it via stubBGCommand and restore on
// cleanup.
func TestMain(m *testing.M) {
	claude.BGCommandRunner = func(workDir string, args []string) ([]byte, error) {
		if len(args) >= 1 && args[0] == "agents" {
			return []byte("[]"), nil
		}
		return nil, fmt.Errorf("BGCommandRunner not stubbed for args %v", args)
	}
	// Insulate the suite from an ambient $FLOW_TERM=bg in the developer's
	// environment: default the whole app package to NON-background so
	// cmdDo tests exercise the terminal path. bg tests opt in via
	// stubBGMode (which saves/restores this override).
