Segue abaixo meu código LeiloesTest.java

package br.com.alura.leilao.leiloes;

import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

import org.junit.Assert;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.NoSuchElementException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import br.com.alura.leilao.login.LoginPage;

public class LeiloesTest {

    private LeiloesPage paginaDeLeiloes;

    @AfterEach
    public void afterEach() {
        this.paginaDeLeiloes.fechar();

    }

    @Test
    public void deveCadastrarLeilao() throws InterruptedException {
        LoginPage paginaDeLogin = new LoginPage();
        paginaDeLogin.preencheFomularioDeLogin("fulano", "pass");
        this.paginaDeLeiloes = paginaDeLogin.efetuarLogin();
        CadastroLeilaoPage paginaDeCadastro = paginaDeLeiloes.carregarFormulario();

        String hoje = LocalDate.now().format(DateTimeFormatter.ofPattern("dd/MM/yyyy"));
        String nome = "Leilão do dia " + hoje;
        String valor = "500.00";

        this.paginaDeLeiloes = paginaDeCadastro.cadastrarLeilao(nome, valor, hoje);
        Assert.assertTrue(paginaDeLeiloes.isLeilaoCadastrado(nome, valor, hoje));

    }

}

E também meu código do LeiloesPage.java

package br.com.alura.leilao.leiloes;

import org.junit.Assert;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.BeforeEach;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class LeiloesPage {

    private static final String URL_LEILOES = "http://localhost:8080/leiloes";
    private static final String URL_CADASTRO_LEILAO = "http://localhost:8080/leiloes/new";
    private WebDriver browser;

    public LeiloesPage(WebDriver browser) {
        this.browser = browser;

    }

    public void fechar() {
        this.browser.quit();

    }

    public CadastroLeilaoPage carregarFormulario() {
        this.browser.navigate().to(URL_CADASTRO_LEILAO);
        return new CadastroLeilaoPage(browser);

    }

    public boolean isLeilaoCadastrado(String nome, String valor, String hoje) {
        WebElement linhaDaTabela = this.browser.findElement(By.cssSelector("#tabela-leiloes tbody tr:last-child"));
        WebElement colunaNome = linhaDaTabela.findElement(By.cssSelector("td:nth-child(1)"));
        WebElement colunaDataAbertura = linhaDaTabela.findElement(By.cssSelector("td:nth-child(2)"));
        WebElement colunaValorInicial = linhaDaTabela.findElement(By.cssSelector("td:nth-child(3)"));

        return colunaNome.getText().equals(nome) && colunaDataAbertura.getText().equals(valor)
                && colunaValorInicial.getText().equals(hoje);
    }

}
