quick code snippet to setup automoq

This is a quick start example of setup mock for Automoq. 

var mocker = new AutoMocker();

var creditCardValidator = mocker.CreateInstance<CreditCardValidator>();

mocker.GetMock<ICreditCardValidator>().Setup(x => x.Validate("fakecardnunber", new DateTime(2024, 12, 12))).Returns(new CreditCardValidationResult("", true));

var result = creditCardValidator.Validate("fakecardnunber", new DateTime(2024, 12, 12));

Assert.IsTrue(result.Valid);                    

There's also option to use other feature like for instance, your class takes a string as part of its constructor. Then you can make use of automoq's use method as shown below. Also notice we using ReturnAsync to work with async 

internal class Vechicle() : IVechicle

{

    public async Task<string> GetMadeModelAsync()

    {

        return await Task.FromResult("testtesttest");

    }

}

internal interface IVechicle

{

    Task<string> GetMadeModelAsync();

}

internal class User(string dummy, IVechicle _vechicle)

{

    public async Task<string> GetModel()

    {

        return await _vechicle.GetMadeModelAsync();

    }

}

// using returnAsync would be much better

[Test]

public async Task TestGetUser()

{

    var mocker = new AutoMocker();

    mocker.Use("toyota");

    var fakeUser = mocker.CreateInstance<User>();

    mocker.GetMock<IVechicle>().

    Setup(x => x.GetMadeModelAsync()).ReturnsAsync("testtesttest");

    var result = await fakeUser.GetModel();

    Assert.That(result, Is.Not.Null);

    Assert.AreEqual("others", result);

    Assert.Pass();

}
