java - 当我使用 Web 驱动程序运行 selenium 测试时，IE 根本没有打开

Question

我是 selenium 新手，我使用 selenium firefox IDE 记录了一个场景。我已将测试用例保存为 java 格式，并尝试使用 selenium-ie 驱动程序和 IEDriverServer.exe 运行测试用例。

这是我的测试用例 java 文件。

package com.xyz.test;

import java.io.File;
import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.support.ui.Select;

public class TestPCQDE {
  private WebDriver driver;
  private String baseUrl;
  private boolean acceptNextAlert = true;
  private StringBuffer verificationErrors = new StringBuffer();

  @Before
  public void setUp() throws Exception {
      File file = new File(TestPCQDE.class.getResource("IEDriverServer.exe").toURI());
      System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
      driver = new InternetExplorerDriver();//IN THIS LINE I GET EXCEPTION POSTED BELOW,IE BROWSER DOES NOT OPEN.PS:driver VARIABLE DOES NOT INITIALIZE PROPERLY
    baseUrl = "http://122.12.122.12:9090/MyWebApp/security/mort_main.htm";
    driver.manage().timeouts().implicitlyWait(3000, TimeUnit.SECONDS);
  }

  @Test
  public void testTestPCQDE() throws Exception {
    driver.get(baseUrl + "/MyWebApp/security/login.htm?logOut=yes");
    driver.findElement(By.name("ssoId")).clear();
    driver.findElement(By.name("ssoId")).sendKeys("abcd");
    driver.findElement(By.name("button")).click();
    driver.manage().timeouts().implicitlyWait(3000, TimeUnit.SECONDS);

    driver.findElement(By.name("strApplicantLastName")).sendKeys("testing");
    new Select(driver.findElement(By.name("maritalStatus"))).selectByVisibleText("Single");
    driver.findElement(By.xpath("//img[@onclick='javascript:cal2.popup()']")).click();
    // ERROR: Caught exception [ERROR: Unsupported command [waitForPopUp | Calendar | 30000]]
    // ERROR: Caught exception [ERROR: Unsupported command [selectWindow | name=Calendar | ]]
    new Select(driver.findElement(By.name("yearSelect"))).selectByVisibleText("1963");

    driver.findElement(By.name("strRecomendedAmount")).clear();
    driver.findElement(By.name("strRecomendedAmount")).sendKeys("5000000");
    driver.findElement(By.xpath("//img[@onclick='javascript:searchProduct();']")).click();
    // ERROR: Caught exception [ERROR: Unsupported command [waitForPopUp | newwin | 30000]]
    // ERROR: Caught exception [ERROR: Unsupported command [selectWindow | name=newwin | ]]
    driver.findElement(By.name("product")).click();
    driver.findElement(By.name("New")).click();
    // ERROR: Caught exception [ERROR: Unsupported command [selectWindow | name=leftFrame | ]]
    new Select(driver.findElement(By.name("strSoftApproval"))).selectByVisibleText("abc xyz");
    driver.findElement(By.id("fanNo")).clear();
    driver.findElement(By.id("fanNo")).sendKeys("0");
    driver.findElement(By.id("productLine")).clear();
    driver.findElement(By.id("productLine")).sendKeys("test 05 01 Vxi");
    driver.findElement(By.name("costOfVehicle")).clear();
    driver.findElement(By.name("costOfVehicle")).sendKeys("40000");
    driver.findElement(By.name("bttnSearch")).click();
    assertTrue(closeAlertAndGetItsText().matches("^Do you want to save the data[\\s\\S]$"));
  }

  @After
  public void tearDown() throws Exception {
    driver.quit();//SINCE VARIABLE driver DOES NOT INITIALIZE PROPERLY,I GET NULL POINTER EXCEPTION
    String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
      fail(verificationErrorString);
    }
  }

  private boolean isElementPresent(By by) {
    try {
      driver.findElement(by);
      return true;
    } catch (NoSuchElementException e) {
      return false;
    }
  }

  private String closeAlertAndGetItsText() {
    try {
      Alert alert = driver.switchTo().alert();
      if (acceptNextAlert) {
        alert.accept();
      } else {
        alert.dismiss();
      }
      return alert.getText();
    } finally {
      acceptNextAlert = true;
    }
  }
}

PS：我已将 IEDriverServer.exe 文件复制到同一文件夹/包（com.xyz.test）中。

这是堆栈跟踪

请注意：我的系统没有管理员权限。我的机器上安装了 IE 8。

如果需要任何其他信息，请告诉我。谢谢

Answer 1

最可能的原因是您的 IEDriverServer.exe 无法启动。尝试明确地将其称为File file = new File("path to file");

从您的堆栈跟踪： 原因：org.openqa.selenium.WebDriverException：等待驱动程序服务器启动超时。
