pytest-liveview 0.1.0

Pytest plugin that shows a real-time test dashboard in a local web server

pytest-liveview

A pytest plugin that shows a real-time test dashboard in a local web server. Watch your tests run live as they execute.

Features

• Real-time updates via Server-Sent Events
• Summary counts: running, passed, failed, skipped
• Expandable test suites with per-suite counts
• Expandable tests with captured output (stdout, stderr, tracebacks)
• Text filter by test/suite name (flexible, space-separated)
• Status filter: all, running, passed, failed, skipped, pending
• Configurable port (default 8085, tries next if busy)
• Optional browser launch via --liveview-open flag

Installation

pip install pytest-liveview

Usage

Run pytest with the --liveview flag:

pytest --liveview

The dashboard URL is printed to stderr and shown in the pytest header, e.g.:

liveview: http://127.0.0.1:8085

To open the browser automatically:

pytest --liveview --liveview-open

Options

Option	Description
--liveview	Enable the liveview dashboard
--liveview-port PORT	Use a specific port (default: 8085)
--liveview-open	Open browser automatically

Troubleshooting

• No output in expanded tests: Don't use -s (which disables capture). Output is captured by default.
• Dashboard not updating / stats stuck on "running": This happens with pytest-xdist (-n 2 or parallel mode). Workers run in separate processes, so updates never reach the dashboard. The plugin auto-disables parallel execution when liveview is enabled. If you use addopts = -n 2 in config, run without it: pytest --liveview (the plugin overrides it).
