延迟OCMock验证/单元测试与超时处理

问题描述

我测试真正的Web服务调用与OCMock。

I'm testing real web service calls with OCMock.

现在我在做的的东西的，如：

- (void)testWebservice
{
    id mydelegatemock = [OCMockObject mockForProtocol:@protocol(MySUTDelegate)];
    [[mydelegatemock expect] someMethod:[OCMArg any]];

    [SUT sutWithDelegate:mydelegatemock];

    // we need to wait for real result
    [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:2.0]];

    [(OCMockObject*)mydelegatemock verify];
}

它工作正常，但它意味着，每一个这样的测试将需要2秒。

It works fine, but it implies that every such test will take 2 seconds.

有没有一种方法我可以设置例如超时2秒，并让 mydelegatemock 到的someMethod 呼叫立即验证并完成测试用例？

Is there a way I can set a timeout of e.g. 2 seconds, and let a call to someMethod of mydelegatemock immediately verify and complete the test case?

推荐答案

我做到这一点使用一个方便实用的功能，我发现的：

I do this using a handy utility function I found at this link:

#import <Foundation/Foundation.h>
#import <OCMock/OCMock.h>

@interface TestUtils : NSObject
+ (void)waitForVerifiedMock:(OCMockObject *)mock delay:(NSTimeInterval)delay;
@end

和实施

#import "TestUtils.h"
@implementation TestUtils

+ (void)waitForVerifiedMock:(OCMockObject *)inMock delay:(NSTimeInterval)inDelay
{
    NSTimeInterval i = 0;
    while (i < inDelay)
    {
        @try
        {
            [inMock verify];
            return;
        }
        @catch (NSException *e) {}
        [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.5]];
        i+=0.5;
    }
    [inMock verify];
}

@end

这让我等待，最多延迟（以秒为单位），而每次等待的全部金额。

This allows me to to wait up to a maximum delay (in seconds) without waiting the full amount each time.
