teachcompute.ext_test_case.measure_time(stmt: str | Callable, context: Dict[str, Any] | None = None, repeat: int = 10, number: int = 50, warmup: int = 1, div_by_number: bool = True, max_time: float | None = None) → Dict[str, Any][source][source]#

Measures a statement and returns the results as a dictionary.

Paramètres:

  • stmt – string or callable

  • context – variable to know in a dictionary

  • repeat – average over repeat experiment

  • number – number of executions in one row

  • warmup – number of iteration to do before starting the real measurement

  • div_by_number – divide by the number of executions

  • max_time – execute the statement until the total goes beyond this time (approximatively), repeat is ignored, div_by_number must be set to True

See Timer.repeat for a better understanding of parameter repeat and number. The function returns a duration corresponding to number times the execution of the main statement.

Modifié dans la version 0.4: Parameter max_time was added.
