# 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.
