Assertj-core: doesNotContainSequence

[mg6maciej]

Summary

There is AbstractIterableAssert.containsSequence, but not the opposite to verify it doesn't contain sequence starting from any index.

Currently I'm using:

assertThat(myList).isNot(Condition(Predicate { it.containsSubList(mySubList) }, "containing sequence"))

where containsSubList is a Kotlin extension method I also had to define:

fun <T> List<T>.containsSubList(other: List<T>)
        = (0..size - other.size).any { subList(it, it + other.size) == other }

I also suggest to create versions of both containsSequence and doesNotContainSequence that accepts List in addition to current vararg ELEMENT.

Example

assertThat(myListOrIterable).doesNotContainSequence(mySubListOrIterable)
assertThat(myListOrIterable).doesNotContainSequence(element1, element2, element3)
assertThat(myListOrIterable).containsSequence(mySubListOrIterable)

Java 8 specific ?

I've done a pull request for the "support Lists in the existing methods" half of your request.

I'll add the doesNotContainSequence methods separately.

[ChrisCanCompute]

I've added doesNotContainSequence but it still needs doesNotContainSubSequence.

Should all be there now.
