Test helper that substitutes a controllable clock into a timer scheduler.
Synopsis
Declared in <bdlmt_timereventscheduler.h>
class TimerEventSchedulerTestTimeSource;Description
This class provides a means to change the clock that is used by a given event‐scheduler to determine when events should be triggered. Constructing a TimerEventSchedulerTestTimeSource alters the behavior of the supplied event‐scheduler. After a test time‐source is created, the underlying scheduler will run events according to a discrete timeline, whose successive values are determined by calls to advanceTime on the test time‐source, and can be retrieved by calling now on that test time‐source. Note that the "system‐time" held by a test time‐source does not correspond to the current system time. Test writers must use caution when scheduling absolute‐time events so that they are scheduled relative to the test time‐source's value for now.
