The Java compiler automatically adds a default no-argument constructor to any classes that do not have a constructor defined.

Here's a link to spring-boot-starter-test which includes JUnit, Mockito, and AssertJ: https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-test

Here is a simple test suite:

public class GifRepositoryTest {
  private GifRepository gifRepository = new GifRepository();

  @Test
  public void findByCategoryId() throws Exception {
    int actual = gifRepository.findByCategoryId(2).size();
    int expected = 3;

    assertThat(actual).isEqualTo(expected);
  }

  @Test
  public void findByName() throws Exception {
    String actual = gifRepository.findByName("android-explosion").getName();
    String expected = "android-explosion";

    assertThat(actual).isEqualToIgnoringCase(expected);
  }
}
