問題描述

有沒有什么技巧可以讓 Win Jenkins slave 使用 chromedriver?

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

我的測試從 maven 存儲庫中提取 chromedriver 和便攜式 chrome，然后執行它們.在我的本地以及當我的構建用戶在我的構建系統上執行相同操作時工作正常.

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.

當 jenkins 做同樣的事情時，即使在前臺(不是 svc)運行時，它也會失敗并出現以下錯誤.我嘗試通過參數來提高詳細程度，但無濟于事.

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.

org.openqa.selenium.WebDriverException:未知錯誤:Chrome 啟動失敗:正常退出(驅動程序信息:chromedriver=2.23.409699 (49b0fa931cda1caad0ae15b7d1b68004acd05129),platform=Windows NT 6.1.7601 SP1 x86_64)(警告:服務器未提供任何堆棧跟蹤信息)命令持續時間或超時:62.63 秒構建信息:版本:'2.41.0'，修訂:'3192d8a6c4449dc285928ba024779344f5423c58'，時間:'2014-03-27 11:29:39'系統信息:主機:'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'驅動程序信息:org.openqa.selenium.chrome.ChromeDriver在 sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)在 sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)在 sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)在 java.lang.reflect.Constructor.newInstance(Constructor.java:422)在 org.openqa.selenium.remote.ErrorHandler.createThrowable(ErrorHandler.java:193)在 org.openqa.selenium.remote.ErrorHandler.throwIfResponseFailed(ErrorHandler.java:145)在 org.openqa.selenium.remote.RemoteWebDriver.execute(RemoteWebDriver.java:595)在 org.openqa.selenium.remote.RemoteWebDriver.startSession(RemoteWebDriver.java:240)在 org.openqa.selenium.chrome.ChromeDriver.startSession(ChromeDriver.java:181)在 org.openqa.selenium.remote.RemoteWebDriver.(RemoteWebDriver.java:126)在 org.openqa.selenium.remote.RemoteWebDriver.(RemoteWebDriver.java:139)在 org.openqa.selenium.chrome.ChromeDriver.(ChromeDriver.java:160)在 org.openqa.selenium.chrome.ChromeDriver.(ChromeDriver.java:128)

我是這樣設置 Chrome 驅動的:

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;
  }
}

我們有幾個問題，關鍵似乎是 Chrome 的無沙盒選項.下面是一個適用于桌面和在前臺或通過服務運行的 jenkins slave 的解決方案.

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 &司機

下載 PortableApps GoogleChrome
安裝
將目錄重命名為通用名稱 (GoogleChrome)
壓縮目錄
添加到存儲庫管理器
設置 maven-dependency-plugin 執行以解包

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>

結果在測試執行時，我們有 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

我們為驅動程序和 chrome exe 的位置設置系統屬性以傳遞給所有單元測試

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:測試代碼

我們使用 chrome 驅動程序服務構建器將詳細程度設置為 11，并使用我們最喜歡的功能啟動驅動程序

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();

}

}
