How to Mock Entity Framework DbContext for Unit Testing

August 06, 2019 by Anuraj

EFCore UnitTesting

This post is about how to mock entity framework DbContext class for unit testing without any third party framework. The dotnet core framework designed and developed considering testability of the apps in mind. Usually for testing the applications which interacts with database, we used to follow two approaches 1) We will be using a repository layer to interact with Database and using any mock framework (without a mocking framework also we can implement it.), we will mock the repository and test the application. 2) Use In Memory Database provider instead of the actual database provider. In this post, I am showing the second approach, the actual code is using SQL Server provider. And for unit testing I am using In Memory provider for EF Core.

Default implementations in interfaces

C# 8.0 C#

This post is about the new C# 8.0 feature Default implementations in interfaces. This feature helps you to provide an implementation for your new method in an interface. So you won’t break existing implementation by adding a new method. From the documentation - An interface member can now be specified with a code body, and if an implementing class or struct does not provide an implementation of that member, no error occurs. Instead, the default implementation is used.

Get all blobs in a container and change the content type.

Azure AzureBlob

This post is about getting all the blobs in a container and change the content type. This tip or snippet is quite useful in scenarios where you want to change content type of big number of blobs. This is a tip or snippet more than a blog post. I faced this issue in my current project, where our application used to push images to Azure Blob, but we were not setting the content type, and by default the content type is application/octet-stream. Because of this, when we used to browse the URL, instead of displaying it in the browser, browser used to show a download prompt. In this I am using a dotnet core console app, which will get all the blobs and if the extension of the file is jpg, setting the content type to image/jpg.
