Unit TestingLEVEL GAME

Create pieces arrayCall move or interactUse getters or return type to verify correct behavior

Test ends (don’t go <0 or >GameEngine.BOARD_SIZE-1)

If interact with adjoining piece, put that piece & yours on board

If interact within range, be sure to test locations within range PLUS one beyond

TEST INDIVIDUAL PIECES

Can’t test random behavior deterministicallyNeed to run method multiple times

Do all possible results actually occur? Do the possible results account for ALL results? (i.e., no

invalid moves)What if LOTS of valid results? (e.g., any location)

Test ends Identify “categories” of possibilities

If limited number of possibilities, test each one E.g., move one to right or left

TEST RANDOM MOVEMENT

What if the player is within “range” of more than one piece?

We’re not testing this, but the approach would be: Create a GameEngine Create a pieces array Add a setter to GameEngine for the pieces array Call interaction

TEST INTERACTION

Criteria Black Box Testing White Box Testing

Definition

Black Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is NOT known to the tester

White Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester.
