/*! * @class XCTestCase
 * XCTestCase is a concrete subclass of XCTest that should be the override point for
 * most developers creating tests for their projects. A test case subclass can have
 * multiple test methods and supports setup and tear down that executes for every test
 * method as well as class level setup and tear down.
 *
 * To define a test case:
 *
 * • Create a subclass of XCTestCase.
 * • Implement -test methods.
 * • Optionally define instance variables or properties that store the state of the test.
 * • Optionally initialize state by overriding -setUp
 * • Optionally clean-up after a test by overriding -tearDown.
 *
 * Test methods are instance methods meeting these requirements:
 * • accepting no parameters
 * • returning no value
 * • prefixed with 'test'
 *
 * For example:

    - (void)testSomething;

 * Test methods are automatically recognized as test cases by the XCTest framework.
 * Each XCTestCase subclass's defaultTestSuite is a XCTestSuite which includes these
 * tests. Test method implementations usually contain assertions that must be verified
 * for the test to pass, for example:
 
    @interface MathTest : XCTestCase {
    @private
        float f1;
        float f2;
    }

    - (void)testAddition;

    @end

    @implementation MathTest

    - (void)setUp
    {
        f1 = 2.0;
        f2 = 3.0;
    }

    - (void)testAddition
    {
        XCTAssertTrue (f1 + f2 == 5.0);
    }
    @end
