test.unexpected_failure: Test ended in a failure it did not expect

Test ended in a failure it did not expect.

Area 13, Testing; not declinable; the next step is usually the agent's.

A call under attempt failed, so the test ended with a failure it didn't check for:

example

test "the top priority can still be raised" {    var bumped: Priority = attempt raise_priority(9)    assert bumped == 9}

text
