How the test is done varies from work to work, though common elements include:
- Done in either a pet store or a factory
- Test involves a yukkuri solving behavioral challenges (such as taking it easy without their accessory) and cognitive challenges (often they're required to be able to solve elementary-level math)
- Attempting a test is usually quite expensive (especially gold ones) with no refunds if you fail. This is the reason why silver or gold badge yukkuris are rather expensive and also the reason why owners get really mad at their pets if they fail a test several times.
