是否有一个技巧让Win Jenkins奴隶与chromedriver合作？
我的测试从maven repo中提取chromedriver和便携式chrome,然后执行它们.我的本地工作正常,当我的构建用户在我的构建系统上做同样的事情.
当jenkins做同样的事情时,即使在前台(而不是svc)中运行它也会失败并出现以下错误.我试过通过params以增加冗长无济于事.

我设置了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;
}
}
解决方法:
我们有几个问题,关键似乎是Chrome的无沙箱选项.以下是适用于桌面和在前台或通过服务运行的jenkins slave的解决方案.
第一部分：Maven Unpack of Chrome&司机
>下载PortableApps GoogleChrome
>安装
>将dir重命名为通用名称(GoogleChrome)
>拉链目录
>添加到存储库管理器
>设置maven-dependency-plugin执行以解压缩
<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,我们使用目标/ chromedriver.exe和target / GooglePortable / Google … exe文件
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,并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();
}
}
