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:
- (void)testExample
{
STFail(@"Unit tests are not implemented yet in learning01Tests");
}
如果我按⌘U,我可以看到测试版并按预期失败。 现在,我添加以下新行以测试我创建的外部类:
#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)按预期失败。 问题在于,有时候,即使我按下命令Test,它会弹出消息“Build succe”然后“Test successful”,但是如果我看输出控制台就会显示“tests run 0”
我做错了吗?
更新
现在我已经更改了我的测试方法的签名,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 标记测试方法,以使其运行。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/
这将有效:
- (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!");
}

您是否验证了目标的构建设置?
这是名为iOS Development Target的关键。如果它以粗体显示,则应按Delete键,使其显示为非粗体,然后,您的单元测试才能正常运行。
如果您想更改iOS开发目标,请执行以下操作:
就是这样。您的单元测试运行正确。
