2 : * @file test_tui_startup.c
3 : * @brief PTY-02 — tg-tui --tui startup, dialog list display, and quit.
4 : *
5 : * Verifies that tg-tui:
6 : * a) Enters raw mode and paints the three-pane TUI layout.
7 : * b) Shows "[dialogs]" in the status row after the dialog pane is
8 : * initialised (even with an empty list).
9 : * c) Exits cleanly (exit code 0) when 'q' is pressed.
10 : * d) Restores the terminal to cooked mode on exit.
11 : *
12 : * Approach:
13 : * - A minimal TCP MTProto stub server (pty_tel_stub) is started in a
14 : * background thread. It seeds session.bin with a matching auth_key so
15 : * that the binary skips the DH handshake and goes straight to the TUI.
16 : * - TG_CLI_DC_HOST / TG_CLI_DC_PORT redirect the binary to the stub.
17 : * - TG_CLI_API_ID / TG_CLI_API_HASH supply fake credentials.
18 : * - HOME is set to a tmp directory so the binary's config/session files
19 : * do not collide with the developer's own config.
20 : * - The binary is launched inside an 80×24 PTY; pty_wait_for() drives
21 : * synchronisation with a 5-second timeout.
