The number of tests should probably be increased, and each test should cover all possible use cases of each commands. Certain existing tests might contain useless lines or need to check more use cases.

Like switches, we should be able to reference a trigger to determine its state.

For example:

story.registerTrigger({
  label: 'created trigger feature',
  trigger: () => { /* something */ },
  then: () => { /* something else */ }

We should be able to query the status of that trigger, like this:

story.triggerStatus('created trigger feature')
// Returns false
