本文介紹了chromedriver 在前臺(tái)運(yùn)行的 windows jenkins slave 上失敗的處理方法，對(duì)大家解決問(wèn)題具有一定的參考價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)吧！

問(wèn)題描述

有沒(méi)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(cè)試從 maven 存儲(chǔ)庫(kù)中提取 chromedriver 和便攜式 chrome，然后執(zhí)行它們.在我的本地以及當(dāng)我的構(gòu)建用戶在我的構(gòu)建系統(tǒng)上執(zhí)行相同操作時(shí)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(dāng) jenkins 做同樣的事情時(shí)，即使在前臺(tái)(不是 svc)運(yùn)行時(shí)，它也會(huì)失敗并出現(xiàn)以下錯(cuò)誤.我嘗試通過(guò)參數(shù)來(lái)提高詳細(xì)程度，但無(wú)濟(jì)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(cuò)誤:Chrome 啟動(dòng)失敗:正常退出(驅(qū)動(dòng)程序信息:chromedriver=2.23.409699 (49b0fa931cda1caad0ae15b7d1b68004acd05129),platform=Windows NT 6.1.7601 SP1 x86_64)(警告:服務(wù)器未提供任何堆棧跟蹤信息)命令持續(xù)時(shí)間或超時(shí):62.63 秒構(gòu)建信息:版本:'2.41.0'，修訂:'3192d8a6c4449dc285928ba024779344f5423c58'，時(shí)間:'2014-03-27 11:29:39'系統(tǒng)信息:主機(jī):'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(qū)動(dòng)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(shè)置 Chrome 驅(qū)動(dòng)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(gè)問(wèn)題，關(guān)鍵似乎是 Chrome 的無(wú)沙盒選項(xiàng).下面是一個(gè)適用于桌面和在前臺(tái)或通過(guò)服務(wù)運(yùn)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(jī)

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(chǔ)庫(kù)管理器
設(shè)置 maven-dependency-plugin 執(zhí)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(jié)果在測(cè)試執(zhí)行時(shí)，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?yōu)轵?qū)動(dòng)程序和 chrome exe 的位置設(shè)置系統(tǒng)屬性以傳遞給所有單元測(cè)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(cè)試代碼

我們使用 chrome 驅(qū)動(dòng)程序服務(wù)構(gòu)建器將詳細(xì)程度設(shè)置為 11，并使用我們最喜歡的功能啟動(dòng)驅(qū)動(dòng)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();

}

}
