如何在unittest中从testsuite获取当前运行的测试用例名称

How can I get currently running testcase name, while in the testsuite collection there are 16 testcases. Tests are executed sequentially (in the order of adding test to the testSuite collection). When I add all tests to testSuite collection I can preview this object but how can I get currently executing test while tests are running. Maybe some variable holds this information?,
