AutoFixture.Freeze IEnumerable of Mocks

Question

我很高兴使用AutoFixture.Freeze<Mock<IViolationChecker>>()设置一个类来测试.Verify()和.Setup()

然而，在我正在研究的课程中，有一大堆IViolationChecker

private readonly IEnumerable<IViolationChecker> _violationCheckers;

我如何使用AutoFixture.Freeze来定义我的IViolationChecker列表？我用过

var violationCheckers = AutoFixture.Freeze<Mock<IEnumerable<IViolationChecker>>>();

但我不确定如何写.Verify()或.Setup()。

Answer 1

一个选项是冻结集合并为每个项目使用Mock.Get来获取用于设置和验证的模拟。

//Arrange
var violationCheckers = AutoFixture.Freeze<IEnumerable<IViolationChecker>>();
var mocks = violationCheckers.Select(item => Mock.Get(item));
foreach (var mock in mocks) {
    mock.Setup(_ => _.SomethingHere()).Verifiable(); //setup mock as desired.
}

//...

//Act
//...exercise member under test

//Assert
foreach(var mock in mocks) {
    mock.Verify(_ => /* some predicate*/, Times.Once);
    //OR
    //mock.Verify();
}

//...
