Test Wiki Shows Up In Google Search Results

I searched for "focus event wpd" -
https://www.google.com/search?q=focus+event+wpd&oq=focus+event+wpd&aqs=chrome..69i57j0l5.3920j0j7&sourceid=chrome&espv=210&es_sm=93&ie=UTF-8#nfpr=1&q=focus+event+wpd

The fourth result is from the test wiki.
Can someone add to robots.txt -
Disallow:
/test/
Or something (I am not sure about the syntax)?
