我只是想让一个简单的测试脚本使用selenium web驱动程序和chrome驱动程序。我有一个maven项目，当它启动我的集成测试时，测试失败并出现以下错误
org.openqa.selenium.WebDriverException: disconnected: Unable to receive message from renderer
我正在使用硒2.44.0和chromedriver 2.44
由于我的测试非常简单，所以我有点卡在这里为什么它不起作用
它在我的测试的设置方法中落在这一行
driver.get("http://www.google.com");
提前致谢
更新：
使用firefox驱动程序时，测试工作正常。因此问题与chromedriver具体相关
我的代码如下
package selenium.selenium_test;
import static junit.framework.Assert.*;

public class SeleniumExampleTest {

@Before

//baseUrl = System.getProperty("webdriver.base.url");
baseUrl = "http://www.google.com";
driver = new ChromeDriver();
driver.get("http://www.google.com");
screenshotHelper = new ScreenshotHelper();
}
@After
public void saveScreenshotAndCloseBrowser() throws IOException {

driver.quit();
}
@SuppressWarnings("deprecation")
@Test
public void pageTitleAfterSearchShouldBeginWithDrupal() throws IOException {
assertEquals("The page title should equal Google at the start of the test.", "Google", driver.getTitle());
WebElement searchField = driver.findElement(By.name("q"));
searchField.sendKeys("Drupal!");
searchField.submit();
assertTrue("The page title should start with the search string after the search.",
(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
return d.getTitle().toLowerCase().startsWith("drupal!");
}
})
);
}
private class ScreenshotHelper {
public void saveScreenshot(String screenshotFileName) throws IOException {
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenshot, new File(screenshotFileName));
}
}
}
