我正在尝试验证传递给后续模拟方法调用(相同方法)的参数值,但无法找出有效的方法。一个通用的例子如下:
public class Foo
{
[Dependency]
public Bar SomeBar
{
get;
set;
}
public void SomeMethod()
{
this.SomeBar.SomeOtherMethod("baz");
this.SomeBar.SomeOtherMethod("bag");
}
}
public class Bar
{
public void SomeOtherMethod(string input)
{
}
}
public class MoqTest
{
[TestMethod]
public void RunTest()
{
Mock<Bar> mock = new Mock<Bar>();
Foo f = new Foo();
mock.Setup(m => m.SomeOtherMethod(It.Is<string>("baz")));
mock.Setup(m => m.SomeOtherMethod(It.Is<string>("bag"))); // this of course overrides the first call
f.SomeMethod();
mock.VerifyAll();
}
}
在安装程序中使用函数可能是一个选项,但似乎我将被简化为某种全局变量,以了解我正在验证哪个参数/迭代。也许我忽视了Moq框架内的明显内容?

Moq区分设置和验证。您可以尝试使用
之类的东西来代替VerifyAll()
mock.Verify(m => m.SomeOtherMethod(It.Is("baz")), Times.Exactly(1));
mock.Verify(m => m.SomeOtherMethod(It.Is("bag")), Times.Exactly(1));

不是说我完全错了或白蚁太宽容了, 但是下面的代码证明了更好的答案:
public interface IA
{
int doA(int i);
}
public class B
{
private IA callee;
public B(IA callee)
{
this.callee = callee;
}
public int doB(int i)
{
Console.WriteLine("B called with " + i);
var res = callee.doA(i);
Console.WriteLine("Delegate returned " + res);
return res;
}
}
[Test]
public void TEST()
{
var mock = new Mock<IA>();
mock.Setup(a => a.doA(It.IsInRange(-5, 100, Range.Exclusive))).Returns((int i) => i * i);
var b = new B(mock.Object);
for (int i = 0; i < 10; i++)
{
b.doB(i);
}
mock.Verify(a => a.doA(It.IsInRange(0, 4, Range.Inclusive)), Times.Exactly(5));
mock.Verify(a => a.doA(It.IsInRange(5, 9, Range.Inclusive)), Times.Exactly(5));
mock.Verify(a => a.doA(It.Is<int>(i => i < 0)), Times.Never());
mock.Verify(a => a.doA(It.Is<int>(i => i > 9)), Times.Never());
mock.Verify(a => a.doA(It.IsInRange(3, 7, Range.Inclusive)), Times.Exactly(5));
// line below will fail
// mock.Verify(a => a.doA(It.IsInRange(3, 7, Range.Inclusive)), Times.Exactly(7));
}
这表明设置与验证完全分开。在某些情况下,这意味着参数匹配必须进行两次:(
