fail now (the task is not implemented) and pass once it is. When the task is one of several \

it names: a scenario, or a part of one, that needs another task of the story — an entry point, a \
message, a selection that task adds — is that task's; leave it out and name it in notes. The \
story's last task tests its scenarios together. Another model will implement \
the task; it cannot change your tests. If the spec has no testable acceptance example \
for this task, return no files. An example whose outcome depends on outside state — the \

behaviour cannot be tested without that state, return no files and say why in notes. \
