How to JUnit test that two List contain the same elements in the same order?

Question

Context

I am writing a simple JUnit test for the MyObject class.

A MyObject can be created from a static factory met

Answer 1

I prefer using Hamcrest because it gives much better output in case of a failure

Assert.assertThat(listUnderTest, 
       IsIterableContainingInOrder.contains(expectedList.toArray()));

Instead of reporting

expected true, got false

it will report

expected List containing "1, 2, 3, ..." got list containing "4, 6, 2, ..."

IsIterableContainingInOrder.contain

Hamcrest

According to the Javadoc:

Creates a matcher for Iterables that matches when a single pass over the examined Iterable yields a series of items, each logically equal to the corresponding item in the specified items. For a positive match, the examined iterable must be of the same length as the number of specified items

So the listUnderTest must have the same number of elements and each element must match the expected values in order.
