How to implement deletion in Junit with Spring Boot?

I need to know how to implement registry exclusion through Junit (Unit Testing) with Spring Boot, I'm having difficulty, the inclusion is working as you can see below;

@Autowired
    private PessoaRepository pessoaRepository;

    @Autowired
    private PessoaService pessoaService;

    @Test
    public void testAdicionarPessoa() throws Exception {
        Pessoa pessoa1 = new Pessoa("Douglas", "399.536.640-64");
        this.pessoaService.salvar(pessoa1);
        // Assertions.assertThat(pessoa1.getName()).isNotNull();
    }

I tried to delete the registry this way, but I did not succeed.

@Test
    public void testeDeletePessoa() throws Exception {
        Pessoa pessoa2 = new Pessoa();
        this.pessoaRepository.delete((long) 4);

    }

I accept suggestions and am open to questions
