expect.arrayContaining passes when received contains all elements from the expected array regardless of element order.
expect.arrayContaining passes when expected contains duplicate elements even if received only contains a single occurrence of that element.
expect.arrayContaining throws an assertion error when received array lacks one or more elements specified in expected.
expect.not.arrayContaining passes when received does not contain the full subset of expected elements.
Passing an empty array to expect.arrayContaining matches any received array.
Non-array received values fail to match expect.arrayContaining even if array-like or iterable.
Nested asymmetric matchers like expect.objectContaining inside expect.arrayContaining successfully match array elements.
