如果需要在同一个类中的每个@Test中运行多个凭据，如何验证登录功能[在Maven POM Selenium项目中]

import org.testng.annotations.Test;

public class LoginTest {
    private String[] credentials = {"user1", "password1", "user2", "password2"};

    @Test
    public void testLogin() {
        for (int i = 0; i < credentials.length; i += 2) {
            String username = credentials[i];
            String password = credentials[i + 1];

            // 执行登录操作
            login(username, password);

            // 验证登录是否成功
            assert isLoggedIn();
        }
    }

    private void login(String username, String password) {
        // 执行登录操作
        // ...
    }

    private boolean isLoggedIn() {
        // 验证登录状态
        // ...
        return true;
    }
}
