How do you Assert two lists in JUnit?
Using JUnit We can use the logic below to compare the equality of two lists using the assertTrue and assertFalse methods. In this first test, the size of both lists is compared before we check if the elements in both lists are the same. As both of these conditions return true, our test will pass.

The assertNotSame() method tests if two object references do not point to the same object. void assertArrayEquals(expectedArray, resultArray); The assertArrayEquals() method will test whether two arrays are equal to each other.
Should I use assertj instead of JUnit?
That is a very common need. With AssertJ the assertion is still simple to write. Better you can assert that the list content are equal even if the class of the elements doesn’t override equals ()/hashCode () while JUnit way requires that :
What are all JUnit Jupiter assertions?
All JUnit Jupiter assertions are static methods in the org.junit.jupiter.api.Assertions class. Let’s start reviewing the assertions available also in JUnit 4. The assertArrayEquals assertion verifies that the expected and the actual arrays are equals:

In details, this assertion accepts a heading, that will be included in the message string for the MultipleFailureError, and a Stream of Executable.
How do I use assertj in Maven?
AssertJ is an opensource community-driven library used for writing fluent and rich assertions in Java tests. To use it in our maven project, let’s add the assertj-core dependency in the pom.xml file: Let’s write a test to compare the equality of two list instance of the same element and same size:
