OCUnit测试用例未运行

如果我创建一个包含单元测试的新项目，则会调用测试用例.但是，当我将测试添加到现有项目时，我在日志中得到以下内容:

If I create a new project which includes unit tests, the test cases get called. But when I'm adding tests to an existing project I'm getting the following in the log:

我已经将SenTestKit添加到框架中，然后通过添加目标"添加了测试包. 我要去哪里错了?

I've added the SenTestKit to the frameworks, and then added the testing bundle via Add Target. Where am I going wrong?

让我在此处添加方法及其测试用例:

Let me add the method and its test case here:

//要测试的方法

-(IBAction)addTask{
    if(!([mPriority.text isEqualToString:@"1"] ||[mPriority.text isEqualToString:@"2"] ||[mPriority.text isEqualToString:@"3"] ||[mPriority.text isEqualToString:@"4"] ||[mPriority.text isEqualToString:@"5"]))
    {
        NSLog(@"Enter valid Priority value");
    }
    else if ([mTaskName.text isEqualToString:@""]) {
            NSLog(@"Task name can't be blank");
        }
        else{
    sqlite3_stmt    *statement;
    const char *dbPath = [mDatabasePath UTF8String];
    //[[appViewController returnObject].mDatabasePath UTF8String];

    if (sqlite3_open(dbPath, &mDiary) == SQLITE_OK)
    {
        NSLog(@"%@",mPriority.text);

        NSString *insertSQL2=[NSString stringWithFormat:@"INSERT INTO TODO VALUES(\"%@\",\"%@\",\"%@\",\"%@\",\"%@\")",mStartDate.text,mEndDate.text,mTaskName.text,mTaskDescription.text,mPriority.text];
        NSLog(@"%@",insertSQL2);
        const char *insert_stmt2 = [insertSQL2 UTF8String];
        sqlite3_prepare_v2(mDiary, insert_stmt2,
                           -1, &statement, NULL);
        NSLog(@"%@",mPriority.text);
        if (sqlite3_step(statement) == SQLITE_DONE )
        { 
            mStartDate.text=@"";
            mEndDate.text=@"";
            mTaskName.text=@"";
            mTaskDescription.text=@"";
            mPriority.text=@"";
        }
        else {

            NSLog(@"failed to add");
        }
        sqlite3_finalize(statement);
        sqlite3_close(mDiary);
        }
    }


}

//这是测试:

-(void)testAddTask
{
    AddTaskViewController *obj;
    obj = [[AddTaskViewController alloc]init];
    obj.mTaskName.text = @"t1";
    obj.mTaskDescription.text = @"t2";
    obj.mStartDate.text = @"56987";
    obj.mEndDate.text = @"55425";
    obj.mPriority.text = @"3";

    [obj addTask];
    sqlite3_stmt *statement;
    const char *dbpath = [obj.mDatabasePath UTF8String];
    if (sqlite3_open(dbpath,&mDiaryTest)== SQLITE_OK) {
        NSString *selectSQL = [NSString stringWithFormat:@"SELECT * FROM TODO WHERE mTaskName = \"%@\"",obj.mTaskName.text];
        const char *query_stmt = [selectSQL UTF8String];
        if (sqlite3_prepare_v2(mDiaryTest,
                               query_stmt, -1, &statement, NULL) == SQLITE_OK)
        {
            if(sqlite3_step(statement) == SQLITE_ROW)
            {
                testString = [[NSString alloc]initWithUTF8String:(const char *) sqlite3_column_text(statement, 1)];
            }
        }
    }
    sqlite3_finalize(statement);
    sqlite3_close(mDiaryTest);
    NSLog(@"%@",testString);
    STAssertEquals(testString,@"t2",@"should be equal");

}

我发现在目标依赖项中，该项​​目未被选中.我检查并再次测试，随后出现以下错误:

I found that in target dependencies the project was unchecked. I checked it and tested again, whereupon I'm getting the following errors:

由于最初的问题完全不同，所以我知道这可能是个话题，但是有人可以告诉我为什么会出现这些错误吗?我已经添加了必要的框架.

I know this is probably going off topic, since the original question was entirely different, but can anyone please tell me why these errors are coming? I've added the necessary frameworks.
