### Testing changes

After making changes, you can test your code in 2 ways:

#### Run tests

- Run `./gradlew :<subproject>:quickTest` where `<subproject>` is the name of the subproject you've changed. 
- For example: `./gradlew :launcher:quickTest`.

#### Install Gradle locally

and try out a change in behavior manually.

**FastAPI** provides a shortcut for these cases, in where the dependency is *specifically* a class that **FastAPI** will "call" to create an instance of the class itself.

For those specific cases, you can do the following:

#### Extension Functions

We’ve migrated from static functions to extension functions where we think they fit.
