objective-c - Xcode 4.2，无法运行单元测试

Question

我创建了一个新的 Xcode 4.2 Cocoa 项目，一个 Cocoa 库。默认情况下，单元测试带有以下单元测试:

- (void)testExample
{
    STFail(@"Unit tests are not implemented yet in learning01Tests");
}

如果我按 ⌘U，我可以看到测试按预期构建和失败。现在，我添加以下新行以测试我创建的外部类:

#import "svc01.h"

- (void)testMyClass
{
    svc01* svc = [[svc01 alloc]init];
    int expected = [svc addTwoNumbers:10 :10];
    STAssertTrue(21 == expected, @"It should fail!");
}

我可以看到两个测试(默认和我的方法)都按预期失败了。问题是有时，即使我按下命令 Test，它也会弹出消息“Build succeed”，然后是“Test succeed”，但如果我查看输出控制台，它会显示“tests run 0”

我做错了什么吗？

更新

现在我已经更改了我的测试方法的签名，但它不再起作用了。我有这个:

#import <SenTestingKit/SenTestingKit.h>

@interface learning01Tests : SenTestCase
- (void)sumTwoIntegerShouldPass;
- (void)sumTwoZeroShouldThrow;

@end
- (void)sumTwoIntegerShouldPass
{
    svc01* svc = [[svc01 alloc]init];
    int expected = [svc addTwoNumbers:10 :10];
    STAssertTrue(20 == expected, @"It should fail!");
}

- (void)sumTwoZeroShouldThrow
{
    svc01* svc = [[svc01 alloc]init];
    int expected = [svc addTwoNumbers:0 :0];
    STAssertTrue(21 == expected, @"It should fail!");
}

这是 Xcode 输出:

在 Xcode 4.2 中，您需要使用前缀 test 标记您的测试方法，以便它们运行。我在这里找到了解决方案: http://www.blog.holsee.com/2011/07/tests-driven-groking-of-cocoa-objective-c/

这会起作用:

- (void)testThatsumTwoZeroShouldThrow
{
    svc01* svc = [[svc01 alloc]init];
    int expected = [svc addTwoNumbers:0 :0];
    STAssertTrue(21 == expected, @"It should fail!");
}

虽然这不会:

- (void)TestThatsumTwoZeroShouldThrow
{
    svc01* svc = [[svc01 alloc]init];
    int expected = [svc addTwoNumbers:0 :0];
    STAssertTrue(21 == expected, @"It should fail!");
}
