在另一个静态类C＃中模拟方法

Question

I want to ask the best way how to mock static a method in an another class. I know that mock is not working for a static class. Here is my Code so far. I don't want to call SearchSomething() at the time because it's external interaction

public ResponseBase GetData(string searchId)
    {
        try
        {
            var request = new SearchRequest 
            {
                SearchId = searchId
            };
            var response = SearchLogic.SearchSomething(request);
            return response;
        }
        catch (Exception e)
        {
            return ResponseBase.ExceptionHandling(e);
        }
    }

public class SearchLogic(){
    public static ResponseBase SearchSomething(SearchRequest request)
    {
        //Do Something
        return  new ResponseBase;
    }
}

This is my UnitClass

[TestClass]
public class UnitClass
{

    [TestMethod]
    public void PositiveSearchTest()
    {
        //arrange
        string searchId = "name";
        var expected = new SearchRequest();
        SearchtController search = new SearchtController();

        var staticMock = new Mock<SearchLogic>();
        staticMock.Setup(s => s.SearchSomething()).Returns(new ResponseBase());

        //act
         var actual = search.GetData(searchId);

        //assert
         Assert.AreEqual(actual, expected);
    }
}

Answer 1

While this question gives one way to solve this, my preferred solution would be different: modify SearchLogic so it is no longer static. After that, you can then mock it to your heart's content. Static methods are always a complete pain for unit testing; I try to use them only for situations where there is one and only one correct behaviour.

This obviously assumes you have the ability to modify SearchLogic . If you don't, see the linked question.
