Regex for negating ends with a match

Question

I need a regular expression to match strings that don't end with certain terms.

Input represents a group of class names such as Foo, FooImpl, FooTest, FooTestSuiteetc.

I want to match anything that doesn't end with Test, Testsor TestSuite.

Must match:

• FooImpl
• FooTestImpl
• Foo

Cannot match:

• FooTest
• FooTestSuite
• FooTests

I just can't get it right. What I have now is wrong, so I won’t even publish it.

Answer 1

Try a negative lookbehind if your language supports it:

/(?<!Test)(<?!Tests)(<?!TestSuite)$/

lookbehind, lookahead:

/^(?!.*(?:Test|Tests|TestSuite)$).*$/
