caso de test na classe AvaliadorTest para testar os 3 menores casos utilizando Hamcrest

Prezado, Gostaria de saber como poderia nessa classe AvaliadorTest, implementar o test dos 3 menores valores, meu test com a biblioteca do JUnit funcionava, nao sei se era o certo, mas quando fui migrar para test com a biblioteca Hamcrest, deu o seguinte mensagem de erro:

"java.lang.AssertionError:  
Expected: (a collection containing <br.com.caelum.leilao.dominio.Lance@c96af00a> and a collection containing <br.com.caelum.leilao.dominio.Lance@44b9f22d> and a collection containing <br.com.caelum.leilao.dominio.Lance@c95af00a> and a collection containing <br.com.caelum.leilao.dominio.Lance@44a0322d>)
     but: a collection containing <br.com.caelum.leilao.dominio.Lance@c96af00a> was <br.com.caelum.leilao.dominio.Lance@44a0322d>, was <br.com.caelum.leilao.dominio.Lance@c95af00a>, was <br.com.caelum.leilao.dominio.Lance@44b9f22d>
