Question

有没有一种很好的方法来测试IDisposable.Dispose（） - 方法的结果？

感谢您的所有答案。

Answer 1

要对Dispose方法进行单元测试，请调用Dispose，然后检查连接，会话和缓存的模拟版本。确保它们已正确关闭并清除。

Answer 2

确保在调用.Dispose()方法后，所有函数和属性getter / setter都返回ObjectDisposedException。

   There are 2 sides to this question:

   1:If there are any mocked objects which in the actual method are getting disposed

    //In actual class properties be like
    public Type SomeObj = new Type();
    -----------------
    //and in dispose() you are disposing it
    public void Dispose()
    {
       SomeObj.Dispose();
    }

    now in test case you can do as follows:
    [Fact]
    public void Sometestmethod()
    {
      var myTestingClass= new TestingClass();
      myTestingClass.Dispose();
      Assert.Equal(null, myTestingClass.SomeObj);
    }

 2: If the obj getting disposed is a private obj

    private SomeType SomeObj;

    public TestingClassCtor(SomeType _someType)
    {
       SomeObj= _someObj;
    }
    --------
    //in dispose method
    public void Dispose()
    {
       SomeObj.Dispose();
    }

    Then to write Ut for this scenario

    [Fact]
    public void SomeTestMethod()
    {
      //This verifies that Dispose method in real class gets executed without any error.
      myTestClass.Dispose();
    }
