The simplest solution is to replace all instances of constants.True and constants.False with True and False, respectively, then delete this dead code from constants.py. So this line in universaldetector.py: self.done = constants.False

job的 执行器,执行job指定的函数 max_instances:执行此job的最大实例数,executor执行job时,根据job的id来计算执行次数,根据设置的最大实例数 来确定是否可执行 next_run_time:Job下次的执行时间,创建Job时可以指定一个时间[datetime],不指定的话则默认根据trigger获取触 发时间 misfire_grace_time:Job的延迟执行时间...

The patching mechanism actually replaced thermmethod of allRemovalServiceinstances in our test method. That means that we can actually inspect the instances themselves. If you want to see more, try dropping in a breakpoint in your mocking code to get a good feel for how the patching mechanism...
