fun <T : Throwable> Expect<T>.messageContains(expected: CharSequenceOrNumberOrChar, vararg otherExpected: CharSequenceOrNumberOrChar): Expect<T>
Expects that the property Throwable.message of the subject of the assertion is not null and contains expected's toString representation and the toString representation of the otherExpected (if given), using a non disjoint search.
It is more or less a shortcut for message { contains.atLeast(1).values(expected, otherExpected) }, depending on
the implementation though.
Notice that a runtime check applies which assures that only CharSequence, Number and Char are passed. This function expects CharSequenceOrNumberOrChar (which is a typealias for Any) for your convenience, so that you can mix String and Int for instance.
AssertionError - Might throw an AssertionError if the assertion made is not correct.
Return
An Expect for the current subject of the assertion.
