selenium - 如何使用 junit4 和 selenium webdriver 使用 chrome 运行我的场景

Question

在 2 天前使用了这个场景并且它有效但一直知道她不知道我不知道为什么，我使用 Selenium webdriver 和 junit4
所以这是我的场景以及我如何使用 cmd 和错误运行 chrome-driver

package com.example.test;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import org.openqa.selenium.*;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
public class SearchWithCH {
  private WebDriver driver;
  private String baseUrl;
  private StringBuffer verificationErrors = new StringBuffer();
  @Before
  public void setUp() throws Exception {
    driver = new RemoteWebDriver(DesiredCapabilities.chrome());
    baseUrl = "http://localhost:8080/";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }
  @Test
  public void testUntitled() throws Exception {
    driver.get(baseUrl + "/myapp/pages/accueil/login.xhtml#loaded");
    driver.findElement(By.id("login")).clear();
    driver.findElement(By.id("login")).sendKeys("login");
    driver.findElement(By.id("password")).clear();
    driver.findElement(By.id("password")).sendKeys("password");
    driver.findElement(By.id("loginButton")).click();
    driver.findElement(By.xpath("//*[@id='mainMenu']/ul/li[2]/a")).click();
    driver.findElement(By.xpath("//*[@id='menu_contact_search']")).click();
    driver.findElement(By.id("formRecherche:nom")).clear();
    driver.findElement(By.id("formRecherche:nom")).sendKeys("Jean");
    driver.findElement(By.id("formRecherche:button_recherche")).click();
    try {
      assertTrue(driver.findElement(By.xpath("//*[@id='panel_contact_id_header']/span")).getText().matches("^[\\s\\S]*Contact : 9673 [\\s\\S]*$"));
    } catch (Error e) {
      verificationErrors.append(e.toString());
    }
  }
  @After
  public void tearDown() throws Exception {
    //driver.quit();
    String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
      fail(verificationErrorString);
    }
  }
}

我运行了 chrome 驱动程序

> java -jar selenium-server-standalone-2.30.0.jar -Dwebdriver.chrome.driver=C:\Users\lenovo\Desktop\Projet\chromedriver_win_26.0.1383.0\chromedriver.exe

但我有这个错误

Answer 1

首先使用以下命令启动 selenium 服务器

java -Dwebdriver.chrome.driver=latest\chromedriver.exe -jar selenium-server-standalone-2.31.0.jar

然后使用下面的逻辑来创建 chrome 驱动程序实例

System.setProperty("webdriver.chrome.driver", "D:\\selenium\\latest\\chromedriver.exe");
DesiredCapabilities dc=new DesiredCapabilities();
dc.setBrowserName("chrome");
driver=new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),dc);

并使用 运行您的测试用例司机 实例

driver.get("http://www.google.com");
