我想对我的Core Data应用进行单元测试(带有许多记录的压力测试)。一切都已设置好以进行单元和应用程序测试，并且工作正常。

我想创建许多核心数据对象，然后查看我的图形视图控制器是否仍然有效。我该怎么做？

如果我在MyAppApplicationTest.m测试类中创建一种测试方法，则该测试将在测试后终止应用，并且无法与图形视图控制器进行交互。

我是否不得不在AppDelegate中创建许多记录并稍后删除该代码？还是有一种使用单元测试框架的方法？

谢谢你的帮助。

最佳答案

UI测试有几种选择。但是，在这种情况下，我建议您建立一个庞大的数据库，并保留它进行各种测试。您可以选择在命令行中，在环境中或仅在用户默认值中设置一个值来使用它。

附带示例代码来检查用户默认设置，然后检查设置环境...

static NSString * findOption(NSString *name) {
    NSString *result = nil;
    NSDictionary *options  = [NSUserDefaults standardUserDefaults];
    if ((result = [options objectForKey:name]) != nil) return result;
    options = [[NSProcessInfo processInfo] environment];
    if ((result = [options objectForKey:name]) != nil) return result;
    return nil;
}

NSDictionary *options  = [[NSUserDefaults standardUserDefaults] volatileDomainForName:NSArgumentDomain];

if ((value = findOption(@"MundiLargeData")) && value.boolValue) {
    // Create the persistent store with the pre-generated big database
    // If creation failed, can continue with normal database as failsafe
}

NSString *value = findOption(@"SenTest");
if (value) {
    NSLog(@"Using SenTest: %@", value);
}

- (void)runAllMethodsThatBeginWith:(NSString*)prefix {
    Class aClass = [self class];
    Method *methods;
    unsigned methodCount;
    if ((methods = class_copyMethodList(aClass, &methodCount)))
    {
        // For this example, we only want methods that take no arguments and return void
        char const *desiredEncoding = method_getTypeEncoding(class_getClassMethod([NSObject class], @selector(load)));

        for (unsigned i = 0; i < methodCount; ++i) {
            SEL selector = method_getName(methods[i]);
            NSString *name = NSStringFromSelector(selector);
            char const * typeEncoding = method_getTypeEncoding(methods[i]);
            NSLog(@"%@: %s %s", name, typeEncoding, desiredEncoding);
            NSRange range = [name rangeOfString:prefix];
            if (range.location == 0 && range.length == prefix.length && strcmp(desiredEncoding, typeEncoding) == 0) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
                [self performSelector:selector];
#pragma clang diagnostic pop
            }
        }

        // Don't forget to free the allocated methods array
        free(methods);
    }
}

[self runAllMethodsThatBeginWith:@"runtimeTest"];

- (void)runtimeTestFoo {
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Create your mondo database
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

#import "AppDelegate.h"
#define APP_DELEGATE AppDelegate

#ifdef USE_MY_SPECIAL_RUNTIME_TEST_DELEGATE
#import "RuntimeTestDelegate.h"
#undef APP_DELEGATE
#define APP_DELEGATE RuntimeTestDelegate
#endif

int main(int argc, char *argv[])
{
    @autoreleasepool
    {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([APP_DELEGATE class]));
    }
}
