Take a look at test cases in CipherSuiteSelectorTest.

Notice that many test cases have the same code, they just each use a different String value for the cipher suite selector / cipher suite strings.

To simplify these test cases, it would be good to introduce a new private method with a body similar to the bodies of the existing methods above but takes the cipher suite selector and cipher suite that should be used as parameters.

The test cases can then be updated to simply call the new helper method with the appropriate parameter(s).
