Dependency-injection

It has been a year since I wrote the article about unit testing with ServiceLocator. But, there are two things worth updating - replacing obsolete FormatterServices and use scoped service provider.

Some testing classes may have a dependency to the ServiceLocator, so the dependencies are injected via property, for example. That makes class more difficult to unit test. In this post I will present how to write unit test for a class with dependency to ServiceLocator, with the real world example of Optimizely.

How to automatically register dependencies in Optimizely? (also in any other project that uses Microsoft.Extensions.DependencyInjection library)
