ERNI.AutoMockExtended 1.0.4

Known Compatibility Issue

SourceCodeGenerator have some known issue with VS 2019 and .Net5 and lower. In order to use this library your device should have .NET 6 installed and you're using Visual Studio 2022 or later. This library is not compatible with lower version of VS in my experience.

Normal Mocking vs AutoCreateMock

Example Interface

public interface ISample
{
     Task<int> GetInt(string input);
     Task<IEnumerable<MyEntity>> Search(string keyword, int pageSize, int pageIndex, string sorting);
}

Normal Mocking

var mock = new Mock<ISample>();
var result = new[] { new MyEntity("abc"), new MyEntity("def") };

mock.Setup(m => m.GetInt(It.IsAny<string>())).ReturnsAsync(20);
mock.Setup(m => m.Search(It.IsAny<string>(), It.IsAny<int>(), It.IsAny<int>(), It.IsAny<string>())).ReturnsAsync(result);

Improved Mocking (using AutoCreateMock)

var mock = new Mock<ISample>();
var result = new[] { new MyEntity("abc"), new MyEntity("def") };

mock.SetupGetInt(20);
mock.SetupSearch(result);

How To Use AutoCreateMock

Register the ISample to AutoMockCreate

use the attribute AutoCreateMock.AutoCreateMock to let the library know that it needs to generate Mock and AutoMock extensions for the specified interface.

public class Mocks
{
    [AutoCreateMock.AutoCreateMock]
    public ISample SampleInterface { get; set; }
}

Sample Usage

Using AutoMock with Setup

public async Task Returns1_ShouldReturn1()
{
     var mock = AutoMock.GetLoose();
     var target = mock.CreateSampleInterface();
     target.SetupGetInt(1);

     var result = await target.Object.GetInt("anystring");

     Assert.Equal(1, result);
}

Using AutoMock with Argument

public async Task Returns1_ShouldReturn1()
{
     var mock = AutoMock.GetLoose();
     var target = mock.CreateSampleInterface(getIntResult: 20);

     var result = await target.Object.GetInt("anystring");

     Assert.Equal(20, result);
}

Using Moq.Mock

public async Task Moq_Returns1_ShouldReturn1()
{
     var target = new Mock<ISample>();
     target.SetupGetInt("abc", 5);

     var result = await target.Object.GetInt("abc");

     Assert.Equal(5, result);
}
