Testing

Put a test block in a .ko file. Tests use ordinary assertions and can call your functions directly.

def double(value: int) -> int:
    return value * 2
 
test "double works":
    assert double(21) == 42

Run the file:

kora test examples/07_tests.ko

Model calls can replay committed cassettes, so tests stay deterministic and free:

kora run --replay examples/01_expense_check.ko

Use mock when a test needs a typed replacement for a model or tool. Keep fixtures small and test both Ok and expected outcome branches.
