fun format(assertion: Assertion, sb: StringBuilder, assertionFilter: (Assertion) -> Boolean): Unit (source)

One can define an assertionFilter to filter out Assertions (for instance, filter out assertions which hold → see CoreFactory.newOnlyFailureReporter).
sb - The StringBuilder to which the formatted assertion will be appended.
assertion - The assertion which should be formatted
assertionFilter - Can be used used to filter out Assertions which should not be formatted.
