How to use

You have a class with lots of mocks...

public class UserManager : UserManager<User>
    {
        /// <summary>
        /// Ctor. 1
        /// </summary>
        public UserManager(IUserStore<User> store, 
                            IOptions<IdentityOptions> optionsAccessor)
        {
        }
        /// <summary>
        /// Ctor. 2
        /// </summary>
        public UserManager(IUserStore<User> store, 
                            IOptions<IdentityOptions> optionsAccessor,
                            IPasswordHasher<User> passwordHasher, 
                            IEnumerable<IUserValidator<User>> userValidators, 
                            IEnumerable<IPasswordValidator<User>> passwordValidators, 
                            ILookupNormalizer keyNormalizer, 
                            IdentityErrorDescriber errors, 
                            IServiceProvider services,
                            ILogger<UserManager<User>> logger)
            : base(store, optionsAccessor, passwordHasher, userValidators, passwordValidators, keyNormalizer, errors, services, logger)
        {
            
        }

        public void Method(IUserPasswordStore<User> store) { ... }
        public void Method(IUserStore<TUser> store) { ... }
    }

How to generate a bag of mocks from any method or constructor?

1. You can get a bag of nedeed mocks just typing:

var mocks = typeof(UserManager).GetMocksFromConstructors(); //11 mocks: 2 from ctor. 1 and 9 from ctor. 2

2. And also you can get only mocks from one specific constructor:

var mocks = typeof(UserManager).GetMocksFromConstructors(new List<Type>{ typeof(IUserStore<User>), typeof(IOptions<IdentityOptions>) }); //2 mocks from ctor. 1

3. Same works for any method:

var mocks = typeof(UserManager).GetMocksFrom("method", new List<Type>{ typeof(IUserPasswordStore<User>) }); //1 mock

If a class is not proxiable and no mock can be created you can check it in the details:

var noMockCouldBeGeneratedForTheseClasses = mocks.Mocks.Where(p => !p.Generated); //Get the errors
var ex = noMockCouldBeGeneratedForTheseClasses.Error; //The thrown exception during mock generation

How to generate a mock for every property type of a class/interface?

Just ask for them 😃

var mocks = typeof(UserManager).GetMocksFromProperties();

How to instantiate a class injecting a bag of mocks?

There are several ways depending on wether the default mocks are valid for you or not. But the easiest way is:

var mocks = typeof(UserManager)
                .GetMocksFromConstructors(); //Get mocks from constructor

var result = mocks.TryInstantiate(out UserManager result); //Get the instance

How to instantiate a class injecting a bag of mocks and custom ones?

var mocks = typeof(UserManager)
                .GetMocksFromConstructors()
                .Select(p => p.Details); //Get mocks from constructor

var customMockToReplace = new Mock<IServiceProvider>();
var result = mocks.TryInstantiate(new List<Mock>() {customMockToReplace}, out UserManager result); //Get the instance replacing your custom mock
