How to use JUnit and Hamcrest together?

Posted by Jennifer | Updated on February 25, 2020

Want to use JUnit and Hamcrest together? junit provides new check assert methods named assertThat() which uses Matchers and should provide a more readable testcode and better failure messages.

To use this there are some core matchers included in junit. You can start with these for basic tests.

package com.test;

import static org.hamcrest.Matchers.empty;

import static org.hamcrest.Matchers.is;

import static org.junit.Assert.assertThat;

import java.util.ArrayList;

import java.util.List;

import org.junit.Test;

public class EmptyTest {

@Test

public void testIsEmpty() {

List myList = new ArrayList();

assertThat(myList, is(empty()));

}
