Refactored Tests
Refactored Tests

Removed test for default positions. It seems arbitrary for the given
problem, the common tests don't include it as a requirement and it seems
best to leave this as a design decision.

Added tests to ensure that queens are placed on the board.

Refactored test to use an inline block, same as the other tests.

Added a version constant test.
