How to compare two List<Float> in Junit?

Question

I need to compare two Lists,

assertEquals(lista1, lista2);
Assert.assertTrue(lista1.containsAll(lista2));

And the error the test shows is

(index:22 size:22) java.lang.Indexoutofboundsexception

Until today I had never tested a return List so I don’t know if I’m doing it right.

Answer 1

Use the methods assertThat class MatcherAssert and the method is class CoreMatchers. Example:

@Test
public void verificaSeAListaASerTestadaEIgualAEsperada() {
    List<Float> listaASerTestada = Arrays.asList(1.0f, 2.0f, 3.0f);
    List<Float> listaEsperada = Arrays.asList(1.0f, 2.0f, 3.0f);
    MatcherAssert.assertThat(listaASerTestada, CoreMatchers.is(listaEsperada));
}
