Any.isNoneOf/isNotIn

Platform (jvm, jdk8, js, android): all

Code related feature

expect(subject).isNoneOf(a, b, ...)
expect(subject).isNotIn(iterable)

//instead of
expect(subject).notToBe(a).notToBe(b)...
expect(subject).notToBe(iterable.next()).notToBe(iterable.next())...

However, reporting should not state multiple not to be (in case of a Reporter which shows all assertions) but reflect the intended grouping.
For instance:

expect(1).isNoneOf(1, 2, 3, 1)

should result in

expect: 1
* is none of:
   - 1

As we can see from the example, we don't have to check for unique values, that's the responsibility of the developer. Moreover, we want fail-fast behaviour (thus we don't see the second 1 in reporting).

Following the things you need to do:

atrium-logic

• extend AnyAssertions with a function isNotIn which expects a List<T> (see existing functions as a guideline)
• implement isNotIn in DefaultAnyAssertions use assertionBuilder.list..
  • add IS_NONE_OF("is none of") to DescriptionAnyAssertion for en_GB
  • add IS_NONE_OF("ist nicht") to DescriptionAnyAssertion for de_CH
    => use it for withDescriptionAndEmptyRepresentation
  • map the elements of List<T> to an assertionBuilder.representationOnly (similar to /domain/robstoll-lib/atrium-domain-robstoll-lib-common/src/main/kotlin/ch/tutteli/atrium/domain/robstoll/lib/creating/iterable/contains/creators/InAnyOrderOnlyAssertionCreator.kt => createExplanatoryGroupForMismatchesEtc) and use them for withAssertions

api-fluent-en_GB

• provide a fun isNoneOf with signature (T, vararg T) (see mapAssertions.kt -> contains as a guideline)
  • add @since 0.9.0 to KDOC
• provide a fun isNotIn with signature Iterable<T>
  • include a require that the Iterable.iterator.hasNext()
  • add @since 0.9.0 to KDOC
• extend AnyAssertionsSpec in specs-common and extend it in atrium-api-fluent-en_GB-common/src/test
