| """Base class for a PressBenchmark. |
| |
| This benchmark manages both PressStory objects that |
| implement javascript based metrics as well as can |
| compute TMBv2 metrics. |
| |
| Example implementation: |
| |
| FooPressBenchmark(press._PressBenchmark): |
| @classmethod |
| def Name(clas): |
| return Foo; |
| |
| def CreateStorySet(): |
| // Return a set of stories inheriting from |
| // page_sets.PressStory |
| |
| def CreateCoreTimelineBasedMeasurementOptions() |
| // Implement to define tracing metrics you |
| // want on top of any javascript metrics |
| // implemented in your stories |
