Question

我是斯威夫特的新手，我似乎无法知道我做错了什么。

我的测试文件如下 - 类型的价值＆＃39; ViewController＆＃39;没有会员＆＃39; averageIsAbove＆＃39;

func testAverageIsAbove75(a: Double, b: Double, c: Double) {
    XCTAssertFalse(testVC.averageIsAbove(a:76, b:75, c:71.9), "Average is below 75, it should return false."  )

MViewController文件将此作为函数：

func averageIsAbove75(a: Double, b: Double, c: Double) -> Bool{
    if (a * b * c) / 3 > 75 {
       return true
    }
    else {
        return false
    }
}

Answer 1

首先，您需要让每个人都能使用该方法。在关键字class之前添加func，以便在ViewController类中添加。{/ p>

接下来，您正在调用testAverageIsAbove，但您的函数名为averageIsAbove75。尝试更改以下内容：

 XCTAssertFalse(testVC.averageIsAbove(a:76, b:75, c:71.9), "Average is below 75, it should return false."  )

对此：

XCTAssertFalse(testVC.averageIsAbove75(a:76, b:75, c:71.9), "Average is below 75, it should return false."  )

Answer 2

class ViewController1 : UIViewController {
   func testAverageIsAbove75(a: Double, b: Double, c: Double) {
       XCTAssertFalse(ViewController2.averageIsAbove75(a:76, b:75, c:71.9), "Average is below 75, it should return false."  )
   }
}


class ViewController2 {
   class func averageIsAbove75(a: Double, b: Double, c: Double) -> Bool{
        if (a * b * c) / 3 > 75 {
           return true
        }
   else {
          return false
        }
    } 
}

无法弄清楚类型的价值＆＃34; ViewController＆＃39;没有会员＆＃39; averageIsAbove＆＃39;
