tests/qa/progress: 31 tests for Progress emitter (was zero coverage)
arborist/qa/progress.py — stage-level state-machine emitter for
arborist query. 85 LOC, no direct tests. Used throughout the QA
runner + ingest pipelines for stderr-only progress lines (stdout
stays clean for JSON / unfirehose journal output).
Coverage:
- Progress.emit formatting: bare-prefix (no kvs), key=value tail
(single + multi), elapsed timestamp format, stream redirect
- enabled=False is true no-op (no string formatting cost)
- default stream is sys.stderr; default t_start is monotonic-now
- disabled() returns singleton (suitable as default kwarg)
- from_env precedence: cli_override > ARBORIST_PROGRESS env >
TTY auto-detect
- 7 truthy env spellings (1/true/on/yes + case variants) enable
- 7 falsy env spellings (0/false/off/no + case variants) disable
- unknown / empty / whitespace env values fall through to TTY
- sys.stderr lacking .isatty falls back to disabled (fail-closed)
- from_env returns fresh instance per call (no shared state)
