Mocking API with Azure Functions

The biggest advantage of Azure Functions is reducing time-to-market of our application. We can also use them to make prototyping more effective. From some time you are able to define mock of our function in Azure Portal. Function defined as mock will respond on request according to its configuration. I believe that this solution has a great potential. It can be very useful in all sort of application’s prototyping activities. You just need to define our end point and its response. And that is all. You can start using it in you prototype. So you define correct connections in your application [...]

As you probably know I wrote two articles about mocking DbSet<TEntity> with Moq: synchronous calls – Mocking DbContext and DbSet with Moq asynchronous calls – EntityFramework – asynchronous queries unit tests I combined those solution to one library and published in on NuGet – Moq.EntityFramework.Helpers. […]

EntityFramework – asynchronous queries unit tests

Sometime ago I described how we can use Moq to unit tests elements of DbContext – please check post Mocking DbContext and DbSet with Moq. Unfortunate that post didn’t covered all issues related to that topic. I didn’t write about unit tests asynchronous queries. Today I want to come back to this issue. We can treat a previous post as a starting point. We already have some code that help us to mock DbSet<T>. And right now we will extend that code to support asynchronous queries. It is very easy. We need only to implement IDbAsyncQueryProvider interface: public class InMemoryAsyncQueryProvider<TEntity> : IDbAsyncQueryProvider { private readonly IQueryProvider innerQueryProvider; [...]

Mocking DbContext and DbSet with Moq

I believe that during your work with unit tests with applications that are using database for data storage you will need to isolate layer that is responsible for providing data. In this example I will use Entity Framework as ORM. Below you can find main elements of solution: public class User { public int Id { get; set; } public string Login { get; set; } public string Name { get; set; } public string Surname { get; set; } public bool AccountLocked { get; set; } public virtual List<Role> Roles { get; set; } } public class UsersContext [...]
