tui-tests

Where tests live

• Main TUI tests: crates/but/src/command/legacy/status/tui/tests/
• Test harness/helpers: crates/but/src/command/legacy/status/tui/tests/utils.rs
• Snapshots: crates/but/src/command/legacy/status/tui/tests/snapshots/

Basic pattern

#[test]
fn describes_behavior_under_test() {
    let env = Sandbox::init_scenario_with_target_and_default_settings("one-stack").unwrap();
    env.setup_metadata(&["A"]).unwrap();

    let mut tui = test_tui(env);
