OCMock：測試方法有一個NSDictionary參數被調用

Question

我有以下類別：

@interface ReportsArchiver 

-(void)fileReport:(NSDictionary*)reports; 

@end 

@interface OfficeManager 

@property (nonatomic) ReportsArchiver* reportsArchiver; 
-(void) reportIncident:(NSString*)name description:(NSString*)description; 

@end 

使用OCMock我想測試調用[officeManager reportIncident:@"fire alarm" description: @"false fire alarm"]當再[officeManager.reportsArchiver fileReport]獲取與字典@{@"name": @"fire alarm", @"description": @"false fire alarm"}調用。

到目前爲止，我已經寫了下面的代碼，這樣做：

OfficeManager* officeManager = [OfficeManager new]; 
id reportsArchiverMock = OCMClassMock([ReportsArchiver class]); 
officeManager.reportsArchiver = reportsArchiverMock; 
NSDictionary* expectedReportDictionary = @{@"name": @"fire alarm", @"description": @"false fire alarm"}; 

[officeManager reportIncident:@"fire alarm" description: @"false fire alarm"]; 

// This call will fail because it checks for object equality, not dictionary equality.  
OCMVerify([reportsArchiverMock fileReport:expectedReportDictionary]); 

我如何可以驗證該[reportsArchiverMock fileReport:{(NSDictionary*)]被調用，相同的NSDictionary使用OCMock？

從那時起，我通過Twitter從@wolffan和@catehstn得到了建議，這裏是我找到的解決方案。

1. 使用OCMExpect - 不像OCMVerify，OCMExpect正確比較NSDictionaries。這是我找到的最乾淨的解決方案。

   OfficeManager* officeManager = [OfficeManager new]; 
   id reportsArchiverMock = OCMClassMock([ReportsArchiver class]); 
   officeManager.reportsArchiver = reportsArchiverMock; 
   NSDictionary* expectedReportDictionary = @{@"name": @"fire alarm", @"description": @"false fire alarm"}; 
   
   OCMExpect([reportsArchiverMock fileReport:expectedReportDictionary]) 
   [officeManager reportIncident:@"fire alarm" description: @"false fire alarm"]; 
   
   OCMVerifyAll(reportsArchiverMock); 
   

2. 使用OCMStub並檢查回調中的參數。這是一個相當混亂的解決方案。

。

OfficeManager* officeManager = [OfficeManager new] 
id reportsArchiverMock = OCMClassMock([ReportsArchiver class]); 
officeManager.reportsArchiver = reportsArchiverMock; 
NSDictionary* expectedReportDictionary = @{@"name": @"fire alarm", @"description": @"false fire alarm"};    

void (^reportIncidentInvocation)(NSInvocation *) = ^(NSInvocation *invocation) { 
     __unsafe_unretained NSInvocationOperation *reportDictionary; 
     [invocation getArgument: &reportDictionary atIndex: 2]; 
     XCTAssertTrue([expectedPropertiesCollection isEqualToDictionary:(NSDictionary*)reportDictionary]); 
    }; 
OCMStub([officeManager reportIncident:[OCMArg any]]).andDo(reportIncidentInvocation); 

OCMVerify([reportsArchiverMock fileReport:expectedReportDictionary]);
