问题描述

有没有什么技巧可以让 Win Jenkins slave 使用 chromedriver?

Is there a trick to getting Win Jenkins slave to be OK with chromedriver?

我的测试从 maven 存储库中提取 chromedriver 和便携式 chrome，然后执行它们.在我的本地以及当我的构建用户在我的构建系统上执行相同操作时工作正常.

My tests pull chromedriver and portable chrome from a maven repo and then execute them. The work fine on my local and when my build users does the same on my build systems.

当 jenkins 做同样的事情时，即使在前台(不是 svc)运行时，它也会失败并出现以下错误.我尝试通过参数来提高详细程度，但无济于事.

When jenkins does the same thing, even when running in the foreground (not a svc) it fails with the error below. I've tried passing params to boost the verbosity to no avail.

我是这样设置 Chrome 驱动的:

I setup the Chrome driver thus:

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;
  }
}

推荐答案

我们有几个问题，关键似乎是 Chrome 的无沙盒选项.下面是一个适用于桌面和在前台或通过服务运行的 jenkins slave 的解决方案.

We have several issues and the key seems to be the no-sandbox option to Chrome. Below is a solution that works on the desktop and on a jenkins slave running in the foreground or via service.

第一部分:Maven 解包 Chrome &司机

• 下载 PortableApps GoogleChrome
• 安装
• 将目录重命名为通用名称 (GoogleChrome)
• 压缩目录
• 添加到存储库管理器

• 设置 maven-dependency-plugin 执行以解包

• Download PortableApps GoogleChrome
• Install
• Rename dir to generic name (GoogleChrome)
• Zip dir
• add to repository manager

• setup maven-dependency-plugin executions to unpack

  <plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
<executions>
 <execution>
   <id>extract portable google chrome</id>
   <phase>process-test-resources</phase>
   <goals>
     <goal>unpack</goal>
   </goals>
   <configuration>
     <skip>${skipWinChromeUnpack}</skip>
     <markersDirectory>${project.build.directory}/dependency-maven-plugin-markers/googlechrome</markersDirectory>
     <overWriteIfNewer>false</overWriteIfNewer>
     <artifactItems>
       <artifactItem>
          <groupId>com.google.chromium</groupId>
          <artifactId>chromedriver</artifactId>
          <version>${win.chromedriver.version}</version>                
          <classifier>win32</classifier>
          <type>zip</type>
        <outputDirectory>${project.build.directory}</outputDirectory>
       </artifactItem>
       <artifactItem>
          <groupId>com.portableapps</groupId>
          <artifactId>googlechrome</artifactId>
          <version>${win.chrome.version}</version>
          <classifier>win64</classifier>
          <type>zip</type>
        <outputDirectory>${project.build.directory}</outputDirectory>
       </artifactItem>
     </artifactItems>
   </configuration>
 </execution>         

结果在测试执行时，我们有 target/chromedriver.exe 和 target/GooglePortable/Google...exe 文件可供使用

Result At test execution time we have target/chromedriver.exe and target/GooglePortable/Google...exe files to use

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

We set System properties for location of driver and chrome exe to pass down to all unit tests

        <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，并使用我们最喜欢的功能启动驱动程序

We use chrome driver service builder to set verbosity to 11 and start the driver using our favorite capabilities from that

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
" + source,
            source.contains("DOCTYPE"));
    driver.quit();
    service.stop();

}

}
