Driving Cypress with
cypress tap
cypress tap
controls an already-running
cypress open
session. Use it to iterate on specs,
inspect the reporter and command log, and read the app under test without GUI interaction.
Use
cypress run
instead for a one-shot headless batch.
Prerequisites
Confirm from package metadata or the lockfile that the resolved Cypress is 15.21.0+ and
contains
tap
. Do not use
tap --help
to probe an unknown older build; prereleases below the
version floor may attempt session discovery instead of printing help.
The session must use Electron, Chrome, Chromium, or Edge. Firefox and WebKit are unsupported.
cypress open
and any configured
baseUrl
dev server must already be running.
The cwd chooses both the Cypress binary and the automatically selected session. When the
target project pins an older Cypress, run
tap
from a compatible checkout and pass
--session
cypress-tap
