问题描述
我创建了一个新的 Xcode 4.2 Cocoa 项目,一个可可库.默认情况下,单元测试带有以下单元测试:
I have created a new Xcode 4.2 Cocoa project, a cocoa library.By default, the unit tests come with the following unit test:
- (void)testExample
{
STFail(@"Unit tests are not implemented yet in learning01Tests");
}
如果我按 ⌘U,我可以看到测试构建并按预期失败.现在,我添加以下新行以测试我创建的外部类:
If I press ⌘U I can see the test building and failing as expected.Now, I add the new following lines in order to test an external class I have created:
#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.问题是有时,即使我按下命令测试,它也会弹出消息构建成功"然后测试成功",但如果我查看输出控制台,它会显示测试运行 0"
I can see both tests (the default and my method) failing as expected.The issue is that sometimes, even if I press the command Test, it popups the message "Build succeed" and then "Test succeed" but if I look at the output console it says "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:
Right now I have changed the signature of my test methods and it does not work anymore.I have this:
#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:
And this is the Xcode output:

推荐答案
在 Xcode 4.2 中,您需要使用前缀 test 标记您的测试方法,以便让它们运行.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/
In Xcode 4.2 you need to mark your test method with the prefix test in order to get them running. I found the solution here: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!");
}
