Creates a scenario whose subject is expected ❌not to satisfy the matcher under test.
Consequently, in the describe() test block generated for this scenario:
❌ in the subtest where the matcher is asserted, the message passed to withError relates to the error that is expected from the matcher.
✅ in the subtest where the matcher is negated by .not, the matcher must succeed.
Example
scenario("when the subject is a number") .subject(7) .fails(e=>e.toBe(90)) .withError("expected 7 to be 90"); //Error when the matcher is not preceded by `.not`
Remarks
You must never use .not when calling the matcher in this scenario: use ✅passes() instead.
