Find and Fix a Problem

1. •

   Use the vscode's build-in tool (execute/runTests) or the runTests tool to run the given unit tests and analyze the output carefully.

2. •

   Analyze the code carefully to find all possible causes of the problem.

3. •

   Think hard to create an extensive list of hypotheses of all possible causes of the problem.

4. •

   Important: Output all your hypotheses!

5. •

   Add extensive print statements to the code that help you confirm or disprove your hypotheses. For example:

Player tick positon += direction print "{this} moved in {direction} to {position}"

	let cell = getCellAt position
	print "{this} landed on cell type {cell?.type} at position {cell?.gridPos}"

6. Run the unit test again and carefully analyze the output of your print statements. The goal is to confirm one of your hypotheses. Repeat steps 1-6 until you can confirm one of your hypotheses.

1. •

   Once you confirmed a hypothesis, fix the problem.

2. •

   Repeat until the given unit test is passing.

3. •

   Remove all the print statements you added.
