Currently the TestLink plugging can match test results based on JUnit suite names, JUnit class names and JUnit test names, but only in isolation.

In our use case, it's the class name with the method name that makes the test unique. The following pull request adds a seeker to meet this requirement: https://github.com/jenkinsci/testlink-plugin/pull/4.

In future, I think we should create one flexible JUnit seeker, that matches a (specified) combination of package name, class name and method name (as appropriate).
