A unit test does not need to run the entire code, instead it just tests certain methods or functions in the application.

You are asked to write unit tests for two of the methods. The code you write in the unit test must check the methods $-$ you can't do it visually.

To determine how your unit test can verify the methods, you will need to determine what input will you need. For example, the unit test might fill the variable called row $($which is a list$)$ in the function create$\_$board$($self$).$ Then it could test is$\_$board$\_$filled$($self$).$ A second test could partially fill the variable row and again test to see the return value from is$\_$board$\_$filled$($self$).$

Now write unit tests for the methods:

is$\_$board$\_$filled$($self$)$

fix$\_$spot$($self$,$ row, col, player$)$

Then run the tests and see if everything passes.
