Unit tests for the new Page implementation to verify it meets the requirements:
|
||
1. Accepts a PageStyle that defines borders, line spacing and inter-block spacing
|
||
2. Makes an image canvas
|
||
3. Provides a method for accepting child objects
|
||
4. Provides methods for determining canvas size and border size
|
||
5. Has a method that calls render on all children
|
||
6. Has a method to query a point and determine which child it belongs to
