chromedriver在前台运行的Windows jenkins从属服务器上失败

selenium

使用chromedriver让Win Jenkins奴隶还可以吗?

我的测试从Maven存储库中提取chromedriver和便携式chrome,然后执行它们。在本地和当构建用户在构建系统上执行相同操作时,工作正常。

当jenkins做同样的事情时,即使在前台运行(不是svc),它也会失败,并显示以下错误。我尝试传递参数来提高详细程度无济于事。

org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited normally (Driver info: chromedriver=2.23.409699 (49b0fa931cda1caad0ae15b7d1b68004acd05129),platform=Windows NT 6.1.7601 SP1 x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 62.63 seconds Build info: version: ‘2.41.0’, revision: ‘3192d8a6c4449dc285928ba024779344f5423c58’, time: ‘2014-03-27 11:29:39’ System info: host: ‘winengbld15’, ip: ‘10.2.2.105’, os.name: ‘Windows Server 2008 R2’, os.arch: ‘amd64’, os.version: ‘6.1’, java.version: ‘1.8.0_40’ Driver info: org.openqa.selenium.chrome.ChromeDriver at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:422) at org.openqa.selenium.remote.ErrorHandler.createThrowable(ErrorHandler.java:193) at org.openqa.selenium.remote.ErrorHandler.throwIfResponseFailed(ErrorHandler.java:145) at org.openqa.selenium.remote.RemoteWebDriver.execute(RemoteWebDriver.java:595) at org.openqa.selenium.remote.RemoteWebDriver.startSession(RemoteWebDriver.java:240) at org.openqa.selenium.chrome.ChromeDriver.startSession(ChromeDriver.java:181) at org.openqa.selenium.remote.RemoteWebDriver.(RemoteWebDriver.java:126) at org.openqa.selenium.remote.RemoteWebDriver.(RemoteWebDriver.java:139) at org.openqa.selenium.chrome.ChromeDriver.(ChromeDriver.java:160) at org.openqa.selenium.chrome.ChromeDriver.(ChromeDriver.java:128)

我这样设置Chrome驱动程序:

defaultPath = "target/drivers/chromedriver.exe";
System.setProperty("webdriver.chrome.driver", defaultPath);
ChromeLocator locator = new ChromeLocator();
driver = new ChromeDriver(locator.getCapabilities());

public class ChromeLocator {
  private static final Logger log = Logger.getLogger(ChromeLocator.class);

  /**
   * Obtain Chrome Configuration with location of binary
   * @return
   * @throws IOException 
   */
  public DesiredCapabilities getCapabilities() throws IOException {
    Map<String, Object> chromeOptions = new HashMap<String, Object>();
    chromeOptions.put("binary", getChromeExecutableLocation().getAbsolutePath());

    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);

    return capabilities;
  }

  // Windows defaults to unpacked location
  private File getChromeExecutableLocation() throws IOException {

    File chromeExe;

    if (SystemUtils.IS_OS_WINDOWS) {
      chromeExe = new File(System.getProperty("win.google.chrome.bin"));  
      log.info("*** win.google.chrome.bin: " + System.getProperty("win.google.chrome.bin"));
    } else {
      // Use the standard locator option for all other operating systems
      GoogleChromeLocator locator = new GoogleChromeLocator();
      BrowserInstallation installation = locator.findBrowserLocationOrFail();
      chromeExe = new File(installation.launcherFilePath());
    }
    log.info("Chrome Exe: " + chromeExe.getAbsolutePath() + " Is File: " + chromeExe.isFile());
    if (! chromeExe.exists() || ! chromeExe.isFile()) {
      throw new IOException("Cannot locate Chrome Executable.  Expected Location: " + chromeExe.getAbsolutePath());
    }
    return chromeExe;
  }
}

我们遇到了几个问题,关键似乎是Chrome的无沙箱选项。以下是在桌面和在前台或通过服务运行的jenkins从站上工作的解决方案。

第一部分:Chrome和驱动程序的Maven解压缩

  • 下载PortableApps GoogleChrome
  • 安装
  • 将目录重命名为通用名称(GoogleChrome)
  • 邮编目录
  • 添加到存储库管理器
  • 设置Maven依赖插件执行以解压
      <plugin>
    

    org.apache.maven.plugins
    maven-dependency-plugin
    2.8


    extract portable google chrome
    process-test-resources

    unpack


    ${skipWinChromeUnpack}
    ${project.build.directory}/dependency-maven-plugin-markers/googlechrome
    false


    com.google.chromium
    chromedriver
    ${win.chromedriver.version}
    win32
    zip
    ${project.build.directory}


    com.portableapps
    googlechrome
    ${win.chrome.version}
    win64
    zip
    ${project.build.directory}



结果 在测试执行时,我们有target / chromedriver.exe和target / GooglePortable / Google
… exe文件要使用

第二部分:Maven Surefire配置

我们为驱动程序和chrome exe的位置设置系统属性,以传递给所有单元测试

        <systemPropertyVariables>
          <webdriver.chrome.driver>${project.build.directory}/chromedriver.exe</webdriver.chrome.driver>
          <win.google.chrome.bin>${win.chrome.exe}</win.google.chrome.bin>  
        </systemPropertyVariables>

第三部分:测试代码

我们使用chrome驱动程序服务构建器将详细程度设置为11,然后使用我们最喜欢的功能启动驱动程序

public class ChromeLocator {
    private static final Logger log = Logger.getLogger(ChromeLocator.class);

/**
 * Obtain Chrome Configuration with location of binary
 * @return
 * @throws IOException
 */
public DesiredCapabilities getCapabilities() throws IOException {
    ChromeOptions chromeOptions = new ChromeOptions();
    chromeOptions.setBinary(getChromeExecutableLocation().getAbsolutePath());
    chromeOptions.addArguments("no-sandbox");
    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);


    return capabilities;
}

// Windows defaults to unpacked location
private File getChromeExecutableLocation() throws IOException {

    File chromeExe;

    if (SystemUtils.IS_OS_WINDOWS) {
        chromeExe = new File(System.getProperty("win.google.chrome.bin"));
    } else {
        // Use the standard locator option for all other operating systems
        GoogleChromeLocator locator = new GoogleChromeLocator();
        BrowserInstallation installation = locator.findBrowserLocationOrFail();
        chromeExe = new File(installation.launcherFilePath());
    }
    System.out.println("Chrome Exe: " + chromeExe.getAbsolutePath() + " Is File: " + chromeExe.isFile());
    if (! chromeExe.exists() || ! chromeExe.isFile()) {
        throw new IOException("Cannot locate Chrome Executable.  Expected Location: " + chromeExe.getAbsolutePath());
    }
    return chromeExe;
}

}

public class WebTest

{
static ChromeDriverService service = null;
static WebDriver driver = null;

@BeforeClass
static public void setupOnce() throws IOException {

    // Setup ChromeDriver with Verbosity on - perhaps control via system property - off by default?
    service = new ChromeDriverService.Builder()
            .withVerbose(true)
            .usingAnyFreePort()
            .build();

    service.start();

    // Setup locator to find unpacked Portable chrome exe
    ChromeLocator locator = new ChromeLocator();

    // Use service + capabilities from locator to open driver with settings and chrome bin
    driver = new RemoteWebDriver(service.getUrl(), locator.getCapabilities());
}

@AfterClass
static public void teardownOnce() {
    if (null != service) {
        service.stop();
        service = null;
    }
}
@Test
public void testGoogleSearch() throws InterruptedException, IOException {
    driver.get("http://www.google.com/xhtml");
    assertEquals("Google", driver.getTitle());

    WebElement searchBox = driver.findElement(By.name("q"));
    String searchString = "ChromeDriver";
    searchBox.sendKeys(searchString);
    searchBox.submit();

    String source = driver.getPageSource().toString();
    assertTrue("Expected DOCTYPE in\n" + source,
            source.contains("DOCTYPE"));
    driver.quit();
    service.stop();

}

}
