Playwright Runner

Run tests

Playwright Runner runs the Playwright installed in your workspace, headless. Results arrive as a progress indicator, a pass or fail notification, an error marker on each failing line, and the full output in a tab.

What you get back

Section titled “What you get back”
  • A progress indicator while the run is in progress; starting another run cancels the first one.
  • A notification such as “1 passed, 0 failed, 0 skipped (0.4s)”; the time is Playwright’s own measurement.
  • An error marker on the failing line until you edit the file or run again. With two or more projects, each failing project gets its own marker and the message starts with the project in brackets, for example [mobile] adds numbers: ....
  • The complete output of the run, one ctrl-. away: see Step labels and run output.
Zed after a single test run: a notification reads "1 passed, 0 failed, 0 skipped" with the time Playwright measured.
A passing run ends with a notification. (Zed 1.26.2, Playwright Runner 0.8.0, Linux (Ubuntu 26.04, GNOME))
tests/failing.spec.ts in Zed with a red error marker on the expect line, the failure message in the diagnostic popup, and an error notification.
A failing run leaves an error marker on the failing line until the file is edited or run again. (Zed 1.26.2, Playwright Runner 0.8.0, Linux (Ubuntu 26.04, GNOME))

Good to know

Section titled “Good to know”
  • Runs use the file on disk. If the buffer has unsaved changes you get a warning and the saved version runs.
  • With several configuration files, the one nearest to the test file is used.
  • Playwright below v1.38 produces a single warning and disables running.
  • Runs pass the selected projects to Playwright and honour the trace viewer and show browser options.
