Directory the entry, relative imports and node_modules lookups resolve against.

Skips the package.json walk when the caller has already done it.

Engine the script runs in. Defaults to chromium.

Port the local server binds. Defaults to 1234.

True when a port was named explicitly, which makes a taken one an error rather than a search.

Re-run on every save instead of exiting after one run.

Run in a visible browser window.

Ms the script may run before it is declared hung; null (the default) is unbounded.

Stdout format when the entry turns out to be a suite. Ignored by a plain script, which has no report to format — its own output IS the output.

Writes a JUnit XML report for a declared suite. Ignored by a plain script.

Prints the server URL and the page's console, as the bare verb's --debug does.

Narrows a declared suite to matching tests. Ignored by a plain script.

Where the script's own output goes, as test() and watch() take one. Defaults to this process's stdout and stderr; pass silentConsole to capture it from the result instead.
