I tested it with basic crashOnlyModificator and it works as intended - allows me to correctly skip and pass all the regular failures and only leaves me with crash tests as failures. Perfect for corner cases like JVM testing and such.

The interface name does not seem to be related with the method it has.

a) If you want `ResultModifier` interface, then the method should probably be `void modify(TestResult result)` rather than passing "status and test description" separately
b) An alternative option could be `TestResultTransfomer extends Function<TestResult, TestResult>`
