Exercise: Create and run a unit test

Background: Board Unit Tests

The game board is covered by unit tests. They are located in the testBoard.cpp file within the test directory. They don't check every single tile on the board, but they do assume that the board shape is not changed significantly. If you change the board layout you might have to change some unit tests to match.

Unit tests are broken down into test cases, in this file it is focused on a test case per function. A TEST_CASE takes two arguments, a test name and a tag. The test name needs to be unique and for the tag we use the section of the game we are testing. Think of them like functions that are called when testing.

Exercise

1. Add a new unit test TEST_CASE for isWall. To test isWall we need to add it the Board.hpp file because it should be accessible within the testBoard.cpp file. Check for a couple of cases, similarly to the isWalkableForPacMan test. Remember since the unit tests are not inside of the pacman namespace, we need to append pacman:: to the function calls.

2. Compile the project and run the unit tests. They should all be passing and if they are not then check which unit test is failing and figure out what was causing the issue. If all goes well you can run the game.
