Moq 函数调用总是返回值,即使输入与模拟输入值不匹配
Moq function call always returning value even though input doesn't match mocked input values
我正在模拟一个带有两个参数的函数调用。
1.输入不可变class对象
2.输出参数.
示例代码:
Mock<ISample> mockSample = new Mock<ISample>();
SampleClass MyKey = new SampleClass() { prop1 = 1 };
SampleOutput output = new SampleOutput() { prop2 = 2 };
mockSample.setup(s => s.SampleMethod(It.is<SampleKey>(t => t.Equals(MyKey)),
out sampleOut))).Returns(true);
在实际代码执行中,如果键与模拟键相同,则此模拟函数 return 正确值,但是,我看到一个问题,即此模拟函数 return 输出值相同如果密钥不匹配。
有任何输入吗?
添加关键代码:
public class Key
{
public readonly DateTime prop1;
public readonly string prop2;
public Key(DateTime prop1, string prop2)
{
this.prop1 = prop1;
this.prop2 = prop2;
}
public override bool Equals(object obj)
{
if (obj == null)
return false;
if (ReferenceEquals(this, obj))
return true;
Key other = obj as Key;
return this.prop1 == other.prop1 && string.Compare(this.prop2, other.prop2);
}
public override int GetHashCode()
{
return prop1.GetHashCode() ^ prop2.GetHashCode();
}
}
据我了解这个问题,您需要针对两种不同的行为设置模拟。请查看示例测试:
[TestFixture]
public class MoqTests
{
[Test]
public void MoqOutParameter()
{
// Arrange
Mock<ISample> mockSample = new Mock<ISample>();
Key MyKey = new Key(DateTime.Today, "SomeValue");
SampleOutput sampleOut = new SampleOutput() { prop2 = 2 };
mockSample.Setup(s => s.SampleMethod(It.Is<Key>(t => t.Equals(MyKey)),
out sampleOut)).Returns(true);
// Act
SampleOutput out1;
var result1 = mockSample.Object.SampleMethod(new Key(DateTime.Today, "SomeValue"), out out1);
SampleOutput out2;
var result2 = mockSample.Object.SampleMethod(new Key(DateTime.MinValue, "AnotherValue"), out out2);
// Assert
Assert.True(result1);
Assert.AreEqual(out1, sampleOut);
Assert.False(result2);
Assert.Null(out2);
}
}
public class Key
{
public readonly DateTime prop1;
public readonly string prop2;
public Key(DateTime prop1, string prop2)
{
this.prop1 = prop1;
this.prop2 = prop2;
}
public override bool Equals(object obj)
{
if (obj == null)
return false;
if (ReferenceEquals(this, obj))
return true;
Key other = obj as Key;
// was forced to add `== 0` to make it compilable
return this.prop1 == other.prop1 && string.Compare(this.prop2, other.prop2) == 0;
}
public override int GetHashCode()
{
return prop1.GetHashCode() ^ prop2.GetHashCode();
}
}
public class SampleOutput
{
public int prop2 { get; set; }
}
public interface ISample
{
bool SampleMethod(Key key, out SampleOutput sampleOut);
}
UPD:我添加了 classes Key
、SampleOutput
和接口 'ISample',我在这个例子中使用了它,还围绕着 class 测试.我正在使用 Nunit 来启动测试,它一定没有意义。您可以根据需要使用任何单元测试框架。这个例子对我有用,测试是绿色的。请尝试一下,并说出与您的环境有何不同。另请注意,我已更改 Key.Equals
中的 return 行以使其可编译。
希望对您有所帮助。
