我想在 Linux 平台（Red Hat Enterprise Linux Server 版本 7.0 (Maipo)）上托管的 Chrome 浏览器上运行我的回归测试。为相同创建了以下示例测试：

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriverService;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import java.io.File;
import java.io.IOException;

public class ChromeTest {

private static ChromeDriverService service;


public static void createAndStartService() throws IOException {
    service = new ChromeDriverService.Builder()
            .usingDriverExecutable(new File("/<pathToChromeDrive>/chromedriver"))
    .withLogFile(new File("/<pathToChromeDriveLogs>/chromedriver.log"))
            .usingAnyFreePort()
            .build();
    service.start();
}


public static void createAndStopService() {
    service.stop();
}


public static void main(String[] args) {
    WebDriver driver;
    try {
        createAndStartService();
        driver = new RemoteWebDriver(service.getUrl(),
                DesiredCapabilities.chrome());
        driver.get("http://www.google.com");
        WebElement searchBox = driver.findElement(By.name("q"));
        searchBox.sendKeys("webdriver");
        driver.quit();
        createAndStopService();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
}

当我尝试在 Linux 上使用 Chrome（版本 - 43.0.2357.81（64 位））作为浏览器运行这个 selenium 测试时，它在出现异常后失败。

Starting ChromeDriver 2.14.313457 (3d645c400edf2e2c500566c9aa096063e707c9cf) on port 3039Only local connections are allowed.Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally  (Driver info: chromedriver=2.14.313457 (3d645c400edf2e2c500566c9aa096063e707c9cf),platform=Linux 3.8.13-35.3.1.el7uek.x86_64 x86_64) (WARNING: The server did not provide any stacktrace information)Command duration or timeout: 60.20 secondsBuild info: version: '2.39.0', revision: 'ff23eac', time: '2013-12-16 16:11:15'System info: host: 'localhost.localdomain', ip: '<>', os.name: 'Linux', os.arch: 'amd64', os.version: '3.8.13-35.3.1.el7uek.x86_64', java.version: '1.8.0_25'Driver info: org.openqa.selenium.remote.RemoteWebDriver

在运行测试之前，我做了以下事情：

  1. Chrome rpm 是从以下链接下载的。“ https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm ”。

  2. 使用以下 chromedriver (2.14.313457)：http ://chromedriver.storage.googleapis.com/2.14/chromedriver_linux64.zip

安装 chrome 后，运行示例测试。

chromedriver 日志如下：

我很确定这是因为 google chrome 和 chromedriver 之间的版本不匹配。问题中给出的链接表明您正在使用 chromedriver 2.14 和当前稳定版本的 google chrome。ChromeDriver 2.14 支持从 v39-42 开始的 google chrome 版本（参见http://chromedriver.storage.googleapis.com/2.14/notes.txt）。根据您使用的 google chrome 版本，使用较新版本的 chromedriver。有关 chromedriver 的正确版本，请参阅http://chromedriver.chromium.org/downloads。

虽然和这个问题无关，但是除非你有特定的需求，否则你不需要手动启动和停止 chromeDriverService。使用以下代码就足够了：

System.setProperty("webdriver.chrome.driver", "E://chromedriver.exe");
WebDriver driver = new ChromeDriver();              
driver.get("http://www.google.com");
