43 Create a progress bar with 10 things.
44 Update it it from 1 to 10. Output a message halfway through.

50 (5) Check message was issued.
51 (6) Check bar is complete

82 =head2 Tests 9--11: Message Check
84 Run a progress bar from 0 to 100, each time calling a message after an update.
85 This is to check that message preserves the progress bar value correctly.
87 ( 1) Check no exception thrown on creation
88 ( 2) Check no exception thrown on update, message (0..100).
89 ( 3) Check last progress is 100%
