ios - 如何模拟 AFHTTPClient 类和测试方法 getPath :parameters:success:failure:?

Question

我是 AFNetworking 框架的新手。我已经实现了对服务器的简单 GET 请求。

@implementation MyClass
…

- (void)signInWithUsername:(NSString *)username andPassword:(NSString *)password withBlock:(SignInBlock)block {
[client getPath:@"test.json" parameters:Nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    block(YES, [responseObject objectForKey:@"access_token"]);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    block(NO, nil);
}];
}

block 声明:

typedef void (^SignInBlock)(BOOL success, NSString *token);

我不知道如何正确模拟此 AFHTTPClient 对象以检查参数 block (SignInBlock) 是否已被调用以及使用什么参数。我怎样才能正确地做到这一点？

提前谢谢您。

我已经做到了。

- (void)testTokenInBlockShouldBeNotNil {

id mockClient = [OCMockObject mockForClass:[AFHTTPClient class]];

[[[mockClient expect] andDo:^(NSInvocation *invocation) {

    void (^successBlock)(AFHTTPRequestOperation *operation, id responseObject) = nil;

    [invocation getArgument:&successBlock atIndex:4];

    successBlock(nil, @{@"access_token" : @"this_is_a_token"});

}] getPath:[OCMArg any] parameters:[OCMArg any] success:[OCMArg any] failure:[OCMArg any]] ;

RKObjectManager *manager = [[RKObjectManager alloc] init];
manager.HTTPClient = mockClient;

TokenBlock block = ^(NSString *token) {
    XCTAssertNotNil(token, @"");
};

CTFAPIConnection *connection = [[CTFAPIConnection alloc] initWithManager:manager];
_accounts = [[CTFAPIAccounts alloc] initWithConnection:connection];
id mockAccounts = [OCMockObject partialMockForObject:_accounts];
[mockAccounts signInWithUsername:[OCMArg any] andPassword:[OCMArg any] withBlock:block];
}
