Description:
Background innformation provided by Facebook:
Abstract:

    The string used to check for the max socket name path len is longer than
    the actual socket string names. When the path is sufficiently long, but
    still within the limit, the longer mysql_testsocket string causes
    problems. Reduce this string to the typical socket pathname instead.

Use case:

There are time when mysql_testsocket would fail even though the actual socket path is shorter than the testsocket name, so change the pathname to be similar to the actual pathname used during the test.
