Override dependency in tests

[nicky-isaacs]

Hello!

I am evaluating Springtime as a longtime Guice fan looking for a Rust alternative. So far it looks great! The one thing I couldn't quite work out is how to override parts of the dependency graph in tests. Assume I have the following hypothetical dependencies FriendService => UserService => SqlClient, in my test I would like to provide a mock implementation for SqlClient and build an instance of FriendService and invoke it in my tests. How can I accomplish this in Springtime? I have been fumbling around with the methods in TypedComponentDefinitionRegistry (register_component_typed sounds relevant but alas I have not been able to crack this)

The simplest way would be to mark your mock component as primary, so it will override the real one. I'll admit, overriding might be something to improve.
