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,

};
