Description

Implementation of a dummy render job for unit tests.

Based on using a specifically rigged DummyClosure as JobFunctor, where the actual Job invocation does nothing other than storing the invocation mark and parameters into a invocationLog_ table. Together with the likewise specifically rigged steam::engine::test::MockJobTicket, the invocation hash can be marked, which allows to prove after the invocation that a given Segment or JobTicket actually generated a specific Job, which was then invoked with specific parameters.

Usage front-end

A MockJob can directly created, and then sliced down to the Job baseclass, since it has no additional data fields. The static functions in MockJob allow to verify that a given job instance was created from this setup, that it was invoked, and verify invocation time and extract data
