Depois de fazer a adição de novos testes não esta mais abrindo o browser:

Oi!

Manda aqui o código das suas classes LeilaoTest e LoginPage

public class LeiloesTest {

private LoginPage paginaDeLeiloes;

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

@Test
public void deveriaCadastrarLeilao() {
    LoginPage paginaDeLogin = new LoginPage();
    paginaDeLogin.preencheFormularioDeLogin("fulano", "pass");
    this.paginaDeLeiloes = paginaDeLogin.efetuaLogin();
    CadastroLeilaoPage paginaDeCadastro = paginaDeLeiloes.carregarFormulario();
}

}

public class LoginPage {

private static final String URL_LOGIN = "http://localhost:8080/login";
private WebDriver browser;    

public LoginPage(WebDriver browser) {
    // TODO Auto-generated constructor Stub    
    System.setProperty("webdriver.chrome.driver", "webdriver/bin/chromedriver.exe");
    this.browser = new ChromeDriver();
    this.browser.navigate().to(URL_LOGIN);

}

public LoginPage() {
    // TODO Auto-generated constructor stub
}

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

}

public void preencheFormularioDeLogin(String username, String password) {
    browser.findElement(By.id("username")).sendKeys(username);
    browser.findElement(By.id("password")).sendKeys(password);

}

public LoginPage efetuaLogin() {
    browser.findElement(By.id("login-form")).submit();
    return new LoginPage(browser);


}

public boolean isPaginaDeLogin() {
    return browser.getCurrentUrl().equals("URL_LOGIN");
}

public String getNomeUsuarioLogado() {
    try {
        return browser.findElement(By.id("usuario-logado")).getText();

    }catch (NoSuchElementException e) {
        return null;
    }

}

public void navegaParaPaginaDeLances() {
    this.browser.navigate().to("http://localhost:8080/leiloes/2");

}

public boolean contemTexto(String texto) {
    return browser.getPageSource().contains(texto);
}

public boolean isPaginaDeLoginComDadosInvalidos() {
    return browser.getCurrentUrl().equals(URL_LOGIN + "?error");
}

public CadastroLeilaoPage carregarFormulario() {
    // TODO Auto-generated method stub
    return null;
}

}

O problema está na sua classe LoginPage. Apague o construtor vazio:

public LoginPage() {
    // TODO Auto-generated constructor stub
}

E no outro construtor remova o parâmetro browser:

public LoginPage() {
    System.setProperty("webdriver.chrome.driver", "webdriver/bin/chromedriver.exe");
    this.browser = new ChromeDriver();
    this.browser.navigate().to(URL_LOGIN);
}

Ficaria assim ?

public LoginPage(WebDriver browser) { System.setProperty("webdriver.chrome.driver", "webdriver/bin/chromedriver.exe");

    this.browser.navigate().to(URL_LOGIN);
