Interactive testing

[therealryan]

Running tests, observing the resulting behaviour and then repeating with slight updates to the test data is an excellent way to learn about a system. It'd be nice to support this use-case by adding an interactive testing facility in the assertion components.

When provoked, a test could throw up a GUI that:

• Allows a flow or flows to be selected
• Allows those flows to be edited
• Allows those flows to be processed via the normal test behaviour
• Allows multiple repetitions of the above loop
• Captures the flow-edit data in the execution report so that if an interesting behaviour is found we've got a record of it so that it can be easily added to the system model.
