toBeNullIfNullGivenElse

inline fun <reified T : Any> <ERROR CLASS><T?>.toBeNullIfNullGivenElse(noinline assertionCreatorOrNull: (<ERROR CLASS><T>.() -> Unit)?): Unit

Deprecated: Switch from Assert to Expect; will be removed with 1.0.0

Makes the assertion that the Assert.subject is either null if assertionCreatorOrNull is null or is not null and holds all assertions assertionCreatorOrNull might create.

It is a shortcut for

if (assertionCreatorOrNull == null) toBe(null)
else notToBeNull(assertionCreatorOrNull)

AssertionError - Might throw an AssertionError if the assertion made is not correct.
