 The vite-task repository has a working implementation of exactly this design, used by ~190 snapshot files today, including interactive selector navigation and ctrl-c cancellation cases. Its pieces:
 
-| Crate | Role |
-| ----- | ---- |
-| `pty_terminal` | Spawns a child in a PTY (`portable-pty`), feeds output through a `vt100` emulator, answers cursor-position queries, handles resize and ctrl-c. Encodes platform workarounds: ConPTY on Windows, a global lock for musl PTY crashes, macOS slave-fd lifetime for EIO truncation. |
-| `pty_terminal_test` | `TestTerminal` wrapper plus `Reader::expect_milestone(name)`: block until the child emits a named milestone, then return the rendered screen. |
-| `pty_terminal_test_client` | Child-side helper that encodes milestones as OSC 8 hyperlinks (`https://milestone.invalid/<hex(name)>` with a zero-width-space anchor), which survive both Unix PTYs and Windows ConPTY and arrive inline with the output they mark. |
-| `snapshot_test` | Minimal snapshot store: compare or update via `UPDATE_SNAPSHOTS=1`, write `<name>.new` on mismatch, return a unified diff as the failure message. |

 On top of these, `vite_task_bin/tests/e2e_snapshots` implements a `libtest-mimic` custom test target: fixtures declare cases in `snapshots.toml`, steps are argv arrays (no shell), interactive steps carry an ordered `interactions` list, and each case produces one Markdown snapshot containing the command lines, the interaction log, and fenced terminal screenshots captured at each milestone and at exit.
