When the user selects the add (+) button in the list view, the task input view is shown. The user can add information for the task. Only the title is required. The Save button can only be selected when a title is given. It is not possible to add a task that is already in the list. The Cancel button dismisses the view. The task input view will look like this:
User stories:
- As a user, given that I have tapped the add (+) button in the item list, I want to see a form to put in the details (title, optional date, optional location name, optional address, and optional description) of a to-do item
- As a user, I want to add a to-do item to the list of to-do items by tapping on the Save button
We will not implement the editing and deletion of tasks. But when you have worked through this book completely, it will be easy for you to add this feature yourself by writing the tests first.
Keep in mind that we will not test the look and design of the app. Unit tests cannot figure out if an app looks like it was intended. Unit tests can test features, and these are independent of their presentation. In principle, it would be possible to write unit tests for the position and color of UI elements. But such things are very likely to change a lot in the early stages of development. We do not want to have failing tests only because a button has moved 10 points.
However, we will test whether the UI elements are present on the view. If your user cannot see the information for the tasks, or if it is not possible to add all the information of a task, then the app does not meet the requirements.
