Class CartesianEnumArgumentsProvider<E extends Enum<E>>

java.lang.Object

org.junitpioneer.jupiter.cartesian.CartesianEnumArgumentsProvider<E>

All Implemented Interfaces:

CartesianArgumentsProvider, CartesianParameterArgumentsProvider<E>

class CartesianEnumArgumentsProvider<E extends Enum<E>>
extends Object
implements CartesianParameterArgumentsProvider<E>

This is basically an enhanced copy of Jupiter's EnumArgumentsProvider, except it does NOT support @ParameterizedTest and implements CartesianParameterArgumentsProvider for use with @CartesianTest.
