public abstract class AbstractFlowExecutionTests
extends junit.framework.TestCase

Base class for tests that verify a flow executes as expected. Flow execution tests authored by subclasses should test that a flow responds to all supported transition criteria correctly, transitioning to the correct states and producing the expected results on the occurrence of external events.

A typical flow execution test case will test:

• That the flow execution starts as expected (see startFlow(MutableAttributeMap, ExternalContext)).
• That a state executes the appropriate transition when an event is signaled. A test case should be authored for each logical event that can occur, where an event triggers a transition representing a path through the flow. The goal should be to exercise all state transitions (see the resumeFlow(ExternalContext) variants and the setCurrentState(String) for more information).
• That given a transition that leads to an interactive state type (such as a view state or an end state), the view selected matches what was expected and the current state of the flow matches what is expected.

A flow execution test can effectively automate and validate the orchestration required to drive an end-to-end business task that spans several steps involving the user to complete. Such tests are a good way to test your system top-down starting at the web-tier and pushing through all the way to the DB without having to deploy to a servlet container. In addition, they can be used to effectively test a flow's execution (the web layer) standalone, typically with a mock service layer.
