public class UserSteps {

    @Step("Verify that the user is logged in")
    public static Predicate<User> isLoggedIn() {
        return user -> user.isLoggedIn();
    }

    @Step("Verify that the user has role {0}")
    public static Predicate<User> hasRole(String role) {
        return user -> user.getRoles().contains(role);
    }

    // ... 其他步骤和方法 ...
