What you need to know
A holds one of five types of value. The type decides how the value is typed in, and which tests a can make on it. An empty value passes one test only: is empty.

Rules that apply to every test
- An empty value fails every test except is empty. It fails is not too.
- Text ignores capital letters: a test for “Commercial” passes on “commercial”.
- A choice must match its option exactly, capital letters too.
- A task or a transition can have up to ten tests. It passes only when every test passes.
Where to add them: Make a task depend on a value. What a failing test does to a task: Why a task is “Not applicable”.
