Selenium HtmlUnit Driver Exception

Question

我正在使用JUnit，Selenium WebDriver，并尝试使用HtmlUnit和 http://vk.com 站点进行一些测试，但失败了。看起来FirefoxDriver对我来说很好用。
这是代码：

@Before
public void setUp() {
    DesiredCapabilities capabilities = DesiredCapabilities.htmlUnit();      
    capabilities.setBrowserName("Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0");
    capabilities.setVersion("24.0");
    capabilities.setJavascriptEnabled(true);
    driver = new HtmlUnitDriver(capabilities);  
    driver.manage().timeouts()
            .implicitlyWait(Integer.parseInt(TIMEOUT), TimeUnit.SECONDS);
    driver.get("http://vk.com");
}
@Test
public void SomeTest() {
    /* LoginPage - described class in PageObject traditions */
    LoginPage start = new LoginPage(driver);
    LOG.info(driver.getPageSource());   
    //...     
}

当我启动它时，我得到一个异常：

    org.openqa.selenium.WebDriverException: com.gargoylesoftware.htmlunit.ScriptException: Exception invoking setInnerHTML
Build info: version: '2.37.0', revision: 'a7c61cb', time: '2013-10-18 17:14:00'

    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)

有什么建议吗？这是黑盒测试，我无权在现场更改内部代码。

Answer 1

Different drivers have different ways to handle javascript. 

Htmlunit使用Rhino，Firefox-driver使用Firefox的默认javascript处理程序，因此，使用不同的驱动程序可以看到不同的结果。

Answer 2

将

htmlUnit()替换为firefox()以进行修复。

DesiredCapabilities capabilities = DesiredCapabilities.firefox()
  capabilities.setBrowserName("Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0");
  capabilities.setVersion("24.0");      
  driver = new HtmlUnitDriver(capabilities);
