public interface Environment extends PropertyResolver, LifeCycle<Environment>, MutableConversionService, ResourceLoader

The current application environment. The environment represents the loaded configuration of the application for a current list of active environment names.

The active environment names can be obtained from the getActiveNames() method and are established from one of the following sources:

When establishing the environment name from the class the started the application Micronaut will inspect the stacktrace. If JUnit or Spock are featured in the stacktrace the TEST environment is included. When running from Android the ANDROID environment is included.
