Performables
Screenplay comes with a few pre-created Abilities, Performables and Builders, for common tasks. Some of these require the installation of additional NuGet packages.
Using a Stopwatch
When an actor needs to keep precise track of time, you may give them the UseAStopwatch ability.
Actors with this ability may use Actions and Questions which relate to use of the stopwatch.
These are all accessible from the builder class StopwatchBuilder.
TimeSpan builder
The TimeSpanBuilder<TOtherBuilder> is not a complete performable builder; it is intended to supplement other builders such as those of your own design.
It handles a commonly-used aspect of building performables in a reusable manner.
