模拟一个包含对象列表的函数

Question

I want to write a test for a method with the following signature

public List<CrateRecallTaskWithComms> PopulateCrateRecallTask(List<Task> listOfBaseTasks)
{
    var crateRecallTasksWithComms = new List<CrateRecallTaskWithComms>();
    foreach (var task in listOfBaseTasks)
    {
        // do stuff

        var crateRecallTasksWithComms = new CrateRecallTaskWithComms()
        {
            // populate properties
        }

        // add to list
        crateRecallTasksWithComms.Add(crateRecallTasksWithComms);
    }

    // return populated list
    return crateRecallTasksWithComms;
}

I am using the Mock library to mock this method, however I cannot get it work! Here is my test code so far:

_crateRecallService = new Mock<CrateRecallsService>();
_crateRecallService.Setup(m => m.PopulateCrateRecallTask(It.IsAny<List<Task>>()).Returns());

I am getting error at the It.IsAny<> bit, the error says:

Argument type System.Collections.Generic.List<Zenos.Intranet.Domain.Tasks.Task> is not assignable to parameter type System.Collections.Generic.List<Task>

What am I doing wrong?

Answer 1

There seems to be two classes named Task .

I think your method expects a list of System.Task , but you're setting it up with a list of Zenos.Intranet.Domain.Tasks.Task . You're probably missing a using directive to disambiguate between the two types..
