pytest-tqdm 0.1.0

A single aggregated tqdm progress bar for pytest, xdist-aware, with failures printed above the bar. Interactive-only.

pytest-tqdm

One tqdm progress bar for your whole pytest run — even under pytest-xdist. Failures print above the bar with full tracebacks; everything else stays quiet. Interactive-only, so it never pollutes CI logs or AI-agent output.

 42%|███████▉           | 512/1210 [00:37<00:48, 14.3test/s, ✓510 ✗2 s0 ▸ test_bar]

…and a one-line summary when the run finishes:

pytest-tqdm ▸ 1210 tests in 01:25  ·  14.2 tests/s  ·  ✓1180 ✗2 s28  ·  8 workers

Why

Under pytest-xdist the usual pretty progress plugins render a bar per file or per worker, and the output interleaves into noise. pytest-tqdm collapses the whole session into a single aggregated bar driven on the xdist controller (which receives every worker's report), so you get one clean line with ETA and throughput — plus failures surfaced immediately, above the bar.

Install

pip install pytest-tqdm

The plugin auto-registers via pytest's pytest11 entry-point. Its only runtime dependency is tqdm.

Usage

By default the bar turns on automatically whenever standard error is an interactive terminal (and you are on the xdist controller, not a worker). In CI, when output is piped, or under an AI coding agent, standard error is not a TTY, so the plugin stays completely silent — your existing reporter is untouched.

pytest -n auto            # bar appears in your terminal, nothing changes in CI

Options

Flag	pytest.ini / env	Effect
(none)	—	Auto-on in a TTY; failures print above the bar with a full traceback.
--tqdm	PYTEST_TQDM=1	Force the bar on even without a TTY.
--no-tqdm	PYTEST_TQDM=0	Force the bar off.
--tqdm-names	tqdm_names (ini)	Also stream every finished test name above the bar.
--tqdm-tb=full|line|no	tqdm_tb (ini)	Traceback verbosity above the bar for failures (default full).

Resolution order for activation: --tqdm / --no-tqdm → PYTEST_TQDM → TTY auto-detection.

The bar

 42%|███████▉    | 512/1210 [00:37<00:48, 14.3test/s, ✓510 ✗2 s0 ▸ test_bar]

percentage · bar · done/total · elapsed<eta · throughput · live ✓/✗/skip tally · current test.

The end-of-run line

When the session finishes the bar is replaced by a single totals line: number of tests, wall time, tests/second, the pass/fail/skip tally, and how many xdist workers ran (serial if you ran without -n).

How it works

• Controller-only. pytest-xdist forwards every worker's pytest_runtest_logreport to the controller, so one reporter there sees all results and drives a single bar. Workers render nothing.
• Summary preserved. The plugin subclasses pytest's TerminalReporter and merely mutes its live per-test writes — all bookkeeping still runs, so the native end-of-run summary, --durations, the failures recap, etc. are untouched.
• stderr. The bar and above-bar text go to standard error; the normal reporter's summary goes to standard out, so they never fight.

Compatibility

• Python 3.9+
• pytest 8 and 9
• Works with and without pytest-xdist; disables pytest-sugar while active (one bar only).
