Xcode 单元测试

项目创建后自动创建的单元测试文件夹， 文件夹名为项目名+tests， xcode6后貌似没有选择是否添加测试target的选择了。

默认生成的如下图

提供的断言如下

typedefNS_ENUM(NSUInteger, _XCTAssertionType) {
    _XCTAssertion_Fail,
    _XCTAssertion_Nil,
    _XCTAssertion_NotNil,
    _XCTAssertion_EqualObjects,
    _XCTAssertion_NotEqualObjects,
    _XCTAssertion_Equal,
    _XCTAssertion_NotEqual,
    _XCTAssertion_EqualWithAccuracy,
    _XCTAssertion_NotEqualWithAccuracy,
    _XCTAssertion_GreaterThan,
    _XCTAssertion_GreaterThanOrEqual,
    _XCTAssertion_LessThan,
    _XCTAssertion_LessThanOrEqual,
    _XCTAssertion_True,
    _XCTAssertion_False,
    _XCTAssertion_Throws,
    _XCTAssertion_ThrowsSpecific,
    _XCTAssertion_ThrowsSpecificNamed,
    _XCTAssertion_NoThrow,
    _XCTAssertion_NoThrowSpecific,
    _XCTAssertion_NoThrowSpecificNamed,
};
