inline fun <reified T : Any> AssertionPlantNullable<T?>.istNichtNull(noinline assertionCreator: Assert<T>.() -> Unit): Unit (source)
Makes the assertion that AssertionPlantNullable.subject is not null and if so, uses assertionCreator which could create further assertions which are added as a group.
AssertionError - Might throw an AssertionError if the assertion made is not correct.
Return
Notice, that this assertion function cannot provide a fluent API because it depends on whether the first
assertion (Assert.subject is not null) holds or not. Define subsequent assertions via
the assertionCreator lambda.
