final def !=(arg0: Any): Boolean

final def ##(): Int

def *[T](implicit default: DefaultValueProvider[T]): T

Alias for org.mockito.matchers.MacroBasedMatchers.any

final def ==(arg0: Any): Boolean

def any[T](implicit default: DefaultValueProvider[T]): T

Delegates to ArgumentMatchers.any(), it's main purpose is to remove the () out of the method call, if you try to do that directly on the test you get this error

final def asInstanceOf[T0]: T0

def clone(): AnyRef

final def eq(arg0: AnyRef): Boolean

final def wait(): Unit

final def wait(arg0: Long, arg1: Int): Unit

final def wait(arg0: Long): Unit

def anyVal[T](implicit default: DefaultValueProvider[T]): T

It was intended to be used instead of any when the argument is a value class, but any now supports value classes so it is not needed anymore
