Game Test

In the screenshot above, the first three inputs are valid game state changes. For example, the first is the sequence of the player going outside, encountering robots and then destroying robots. The second is the sequence of the player going outside, encountering robots and getting killed with the laser beams from robots. The third is the sequnce of the player going outside but getting killed by robots shooting laser beams without encountering any robots.

The last three inputs are not supposed to happen. The input “Go_OutsideRobot_Kills” means the player goes outside but gets killed by robots right away. Moroever, the input “Go_OutsideEncounter_RobotRobot_Kills” means the player goes outside, encounters robots, and gets killed by robots. These two inputs are illegal moves because robots have to first shoot laser beams in order to kill the player. The last input means the player goes outside, hides, and gets killed by robots. This is illegal since robots cannot kill the player when the player is hidden.
