Test.Util.Schedule

Description

Utilities to schedule actions per Tick.

Synopsis

newtype Schedule a = Schedule {
- getSchedule ∷ Map Tick [a]
}
genSchedule ∷ [a] → Gen (Schedule a)
joinSchedule ∷ Schedule a → [a]
lastTick ∷ Schedule a → Tick
shrinkSchedule ∷ Schedule a → [Schedule a]

Documentation

newtype Schedule a Source #

A schedule plans actions on certain times.

TODO Note that a schedule can't express delays between the actions within a single tick. Generating such delays may expose more (most likely concurrency-related) bugs.

genSchedule ∷ [a] → Gen (Schedule a) Source #

Spread out elements over a schedule, i.e. schedule a number of elements to be processed on each tick. Most ticks will have no associated elements.

joinSchedule ∷ Schedule a → [a] Source #

Inverse of genSchedule

lastTick ∷ Schedule a → Tick Source #

Return the last tick at which an update is planned, if no updates are planned, return 0.

shrinkSchedule ∷ Schedule a → [Schedule a] Source #

Repeatedly remove the last entry (highest Tick)
