-- moving reply from dropwizard-dev to here
Hey Robin,
This page goes into more detail about how the application starts up:
https://www.dropwizard.io/1.3.12/docs/manual/internals.html
Depending on where in the lifecycle you want to cut in at, you could
directly call the Application.run(args) method or if you want to bypass
most everything Dropwizard is doing, you can look at what the
ServerCommand.run() method does.
You also could look at the DropwizardTestSupport class from the
dropwizard-testing module to see how the application is started/stopped for
integration tests.
