Telerik.JustMock.EntityFramework
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.
