SubsystemRunner_test Class Reference

Description

Test:

managing start and stop of several dependent "subsystems" under various conditions.

Using mock-subsystems, which actually spawn a thread and finish by themselves and generally behave sane. For each such MockSys, we can define a behaviour pattern, e.g. weather the start succeeds and if the run terminates with error.

Note

as this test focuses on the SubsystemRunner, the mock subsystem is implemented rather simplistic. Especially, there is a race when a subsystem is configured to "fail" – because in this case the starting context may go away before the remainder of the subsystem thread has executed after the sync() barrier. Especially in this case, no MockSys actually starts without failure, and thus the SubsystemRunner::wait() has no guarding effect. This can be considered a shortcoming of the test fixture; a well behaved subsystem won't just go away...
