@brunchika: You do not need to add Quotes on the pattern, but you are required to use delimiters by default of PHP. Try pattern: /test/ subject: asdftestasdf and click run.

Good testing functionality, however, I noticed that the input in the $pattern field must be within single or double quotes otherwise an error is posted. Curiously however the $subject field doesn't have to be within quotes. So that was the bit of inconsistency I noticed. Note: The quotes on both fields are added automatically after the run button is pressed therefore why the need of quotes in the $pattern input field?
