Spring Sellenium前端测试-初始化问题

Question

我使用Selenium (Firefox Web驱动程序)进行前端测试。

当我尝试获取主页的基本URL时，浏览器打开，地址栏保持为空。

下面是我的代码：

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;


@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = com.mycompany.application.MyApp.class)
@WebAppConfiguration
public class SpringFrontEndTest {

    private WebDriver driver;

    private static final String BASE_URL = "http://localhost:3000/#/";

    @Before
    public void initWebDriver(){
        driver = new FirefoxDriver();
    }

    @Test
    public void simpleTest() throws Exception
    {
        driver.get(BASE_URL);
    }

    @After
    public void closeDriver(){
        driver.close();
    }
}

下面是堆栈跟踪：

有谁对这个问题有什么想法吗？

提前谢谢你！

Answer 1

加载网页需要时间。您要在页面加载之前关闭驱动程序。之后

driver.get(BASE_URL) 

添加：

Thread.sleep(15000);

15秒应该足以加载页面，但如果页面非常慢，则增加休眠的毫秒数。

这条线

Caused by: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:7055 [/127.0.0.1] failed: Connection refused

听起来有点可疑。您可以检查您的/etc/hosts文件，并确保您有以下类型的映射吗？

127.0.0.1 localhost
