how to match "test\w*" but not "tester" with a single regex expression

Question

Say I have the following string:

test tester tested testing

I wish to match every word that begins with test, but not the word tester. The pattern test\w* does most of the job, but I have no idea how to add that tester should not be matched. A working pattern should give 3 matches on the string.

Does this work for your purposes?

test(?!er).*

That matches the whole string, `test(?!er)\w*` works however. – user1151923 Oct 30 '14 at 10:52
