Function TestIsBackground

internal/spawner/spawner_test.go:18–39

TestIsBackground verifies the bg-mode selector. $FLOW_TERM=bg means "spawn as a terminal-free background agent" — distinct from the terminal backends Detect() returns, so it lives in its own predicate that do.go checks before any SpawnTab.

(t *testing.T)

// terminal backends Detect() returns, so it lives in its own predicate
// that do.go checks before any SpawnTab.
func TestIsBackground(t *testing.T) {
	cases := []struct {
		flowTerm string
		want     bool
	}{
		{"bg", true},
		{"", false},
		{"iterm", false},
		{"BG", false}, // case-sensitive, mirrors Detect's exact match
		{"background", false},
	}
	for _, tc := range cases {
		t.Run(tc.flowTerm, func(t *testing.T) {
			t.Setenv("FLOW_TERM", tc.flowTerm)
			BackgroundOverride = nil
			if got := IsBackground(); got != tc.want {
				t.Errorf("IsBackground() with FLOW_TERM=%q: got %v, want %v",
					tc.flowTerm, got, tc.want)
			}
		})
	}
}

// TestBackgroundOverrideBeatsEnv confirms the test escape hatch: setting
// BackgroundOverride pins IsBackground regardless of $FLOW_TERM, so tests
