elementary lisp variable == string

Hello Sorry for this elementary question. I have say defined (defvar isp "hallo" "*change if you want") Now in a function I want to execute certain code - if isp is indeed the string "hallo" and - if isp is the string "test" then another part of the code will be executed. So if the variable would just take the values t and nil it is clear how to do it, but in the case of a string? I thought string-match might do it but no I does not.
