By using 'iterableWithSize’ method, you can create a matcher that is used to check the size of iterable.
Ex
assertThat(list, Isiterablewithsize. iterableWithSize(3));
(or)
assertThat(list, IsIterableWithSize. iterableWithSize(equalTo(3)));
Find the below working application.
TestApp.java
package com.sample.tests;
import static org.hamcrest.MatcherAssert.assertThat;
import java.util.Arrays;
import java.util.List;
import org.hamcrest.collection.IsIterableWithSize;
import static org.hamcrest.Matchers.equalTo;
import org.junit.Test;
public class TestApp {
@Test
public void testmethod() {
ListInteger> list = Arrays.asList(5, 3, 2);
assertThat(list, IsIterableWithSize.Integer> iterableWithSize(3));
// You can also compare like below.
assertThat(list, IsIterableWithSize.Integer> iterableWithSize(equalTo(3)));
}
}
