Test Writing: Drop Bear Safety

Created By: Geoffrey Challen

/ Version: 2026.2.0

The drop bear is a fearsome creature from Australian folklore -- a large, carnivorous koala that drops from trees onto unsuspecting tourists. (Don't worry, they're not real... probably.)

Create a function called dropBearDanger that accepts three Boolean parameters:

• hasVegemite: whether you have Vegemite behind your ears (a well-known drop bear repellent)
• underEucalyptus: whether you are standing under a eucalyptus tree
• isNighttime: whether it is nighttime

Return a String indicating your danger level:

• If hasVegemite is true, return "Safe" -- Vegemite always protects you, regardless of other conditions.
• If underEucalyptus and isNighttime are both true, return "Extreme danger!".
• If either underEucalyptus or isNighttime is true (but not both), return "Moderate danger".
• Otherwise, return "Low danger".

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Kotlin's assert or check methods
