In-memory mock DbSet and DbContext mocking amenities for JustMock.

Mocking DbContext

Here is an example straight from the tests:

[TestClass]
public class DbContextTests
{
	public class Person
	{
		public int Id { get; set; }
		public string Name { get; set; }
	}

	public class DbContextOne : DbContext
	{
		public DbSet<Person> People { get; set; }
	}

	[TestMethod]
	public void Prepare_ShouldAssignDbSetProperties()
	{
		var dbContext = EntityFrameworkMock.Create<DbContextOne>();
		Assert.IsNotNull(dbContext.People);
	}
}

In the above example I create a mock of my DbContext-deriving class. As a result, all fields that are of type DbSet<T> or IDbSet<T> are automatically populated with a mock in-memory DbSet (initially empty).

We can also create a mock from a DbContext-like interface, like in the example below:

public interface IMyDbContext
{
	IDbSet<Person> People { get; }
}

[TestMethod]
public void Prepare_Interface_DbSetsInitialized()
{
	var dbContext = EntityFrameworkMock.Create<IMyDbContext>();
	Assert.IsNotNull(dbContext.People);
}

Populating data

Populating the context with data lets you simulate a database that has data in it. Here's how we can populate our context:

[TestMethod]
public async Task Bind_BindData_DataIsThere()
{
	var ctx = Mock.Create<TheDbContext>().PrepareMock();

	var list = new List<Person>
	{
		new Person { Id = 1, Name = "a" }
	};

	ctx.People.Bind(list);

	var data = await ctx.People.ToListAsync();
	Assert.AreSame(list[0], data[0]);
}

The Bind() extension method binds a DbSet or IDbSet on the mock context to a backing collection, which can be anything, but it's best to use a ObservableCollection<T> (Local works only when the backing collection is itself observable).

Changes made to the DbSet are passed to the backing collection and vice versa.
