* minesweeper: update tests to version 1.1.0 Add missing test version comment. Add ordered tests with names matching canonical data descriptions. Disable empty board tests which are incompatible with board class. Move selected old tests to additional tests section. Convert no row/column tests to expect validation to raise ValueError. Closes #998 * minesweeper: update test data to canonical format 1.0.0 Update test data to borderless format which matches canonical data format. Change board verification to not test for borders and default example to properly return a completely empty board and account for new index when there is no border.

The board function must validate its input and raise a
