Kezia ran a test transaction before going live with crypto payments. What was the main purpose of doing this?

A test transaction checks that the full payment process works: the customer pays, the processor converts, and the correct dollar amount arrives in the business account. Running one before going live catches any configuration issues while the stakes are low and there is no minimum payment amount so the test transaction can be for a very small amount. It also gives the business owner a concrete experience of what a crypto payment looks and feels like from both sides of the transaction.
