In-process acceptance testing

Acceptance tests generally exercise the system from the ‘outside’, traversing an entire network stack for the security of exercising the complete application. In-process acceptance testing challenges the notion that test code and application under- test must run in different processes in order to achieve these benefits. When using an embedded container, it is easy to set up the system, run the tests over HTTP and to verify the final state without the setup costs associated with deploying to and communicating with a separate container.
