iOS TestSuite example with XCTest

Here is my test file

- (void)setUp{ [super setUp]; }

- (void)tearDown{ [super tearDown]; }

- (void)test0{ //.. }

- (void)test1{ //.. }

Now I want to add test0 and test1 to a testSuite, I notice that there is API for "XCTest/XCTestSuite.h" provided by XCTest, but I have no idea how to use it. Anyone can help me ?
