NSubstitute完全手册(十三)抛出异常

当一个成员被调用时,也可使用回调来抛出异常

 1     public interface ICalculator
 2     {
 3       int Add(int a, int b);
 4       string Mode { get; set; }
 5     }
 6 
 7     [TestMethod]
 8     [ExpectedException(typeof(Exception))]
 9     public void Test_ThrowingExceptions_ForVoid()
10     {
11       var calculator = Substitute.For<ICalculator>();
12 
13       // 对无返回值函数
14       calculator.Add(-1, -1).Returns(x => { throw new Exception(); });
15 
16       // 抛出异常
17       calculator.Add(-1, -1);
18     }
19 
20     [TestMethod]
21     [ExpectedException(typeof(Exception))]
22     public void Test_ThrowingExceptions_ForNonVoidAndVoid()
23     {
24       var calculator = Substitute.For<ICalculator>();
25 
26       // 对有返回值或无返回值函数
27       calculator
28         .When(x => x.Add(-2, -2))
29         .Do(x => { throw new Exception(); });
30 
31       // 抛出异常
32       calculator.Add(-2, -2);
33     }
