Xcode unit test -- setup and teardown only once

Question

Is it possible to setup a unit test class to call setup and teardown methods only once for all the test cases not for each test case?

Answer 1

Check this from Apple document

Answer 2

Actually I found the answer. In order to do class level setup, one needs to implement +(void) setUp and +(void) tearDown. This class methods will be called before any test methods run and after all of the test methods run.
