Fleet provides helpers for UIBarButtonItem similar to those provider for UIButton. Here is the normal
flow for testing taps on UIBarButtonItem objects:
// Problematic for several reasons:
// 1) Not intuitive -- especially for those new to iOS
// 2) Many points of failure with no indication of what went wrong. Maybe I did not
// link my target or action correctly? Or maybe the implementation of the action is
// wrong?
let someBarButtonItem = viewControllerWithNavBar.rightBarButton
someBarButtonItem.target?.perform(someBarButtonItem.action, with: someBarButtonItem)Instead, you can use the Fleet extension tap like so:
// Simple to understand, and also throws an error when something goes wrong not
// related to the action implementation:
// 1) target improperly hooked up
// 2) action improperly hooked up
// 3) The button is not enabled
let someBarButtonItem = viewControllerWithNavBar.rightBarButton
try! someBarButtonItem.tap()
