Generate two object of the same mock

Question

I'm using MoQ in C# to do some Unit tests/BDD tests, and I've often the need of generating the same object twice(because it will be potentially used in dictionary). Or something 99% the same but just with a different ID.

Is there a way to "clone" the Mock definition? Or to generate two objects with the same definition?

Answer 1

You should create a helper method that constructs that takes in some parameters to construct the Mock object.

[Test]
public void MyTest()
{
    Mock<ITestObject> myMock = CreateObject(1);
    ITestObject obj = myMock.Object;
}

private Mock<ITestObject> CreateObject(int id)
{
    Mock<ITestObject> mock = new Mock<ITestObject>();
    mock.SetupGet(o => o.ID).Returns(id);
    return mock;
}

private interface ITestObject
{
    int ID { get; set; }
}
