Question

我正在Jenkins ECS从站上使用ChromeDriver设置基于硒的回归测试。

ChromeDriver使用Maven插件"driver-binary-downloader-maven-plugin"

安装在ECS从站上

登录docker容器时，我看到安装了ChromeDriver /usr/bin/linux/googlechrome/64bit/chromedriver

Docker容器以--privileged

开始

pom.xml

<plugin>
    <groupId>com.lazerycode.selenium</groupId>
    <artifactId>driver-binary-downloader-maven-plugin</artifactId>
    <version>1.0.17</version>
    <configuration>
        <rootStandaloneServerDirectory>/usr/bin</rootStandaloneServerDirectory>
        <downloadedZipFileDirectory>drivers/zips</downloadedZipFileDirectory>
    </configuration>
    <executions>
        <execution>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>selenium</goal>
            </goals>
        </execution>
    </executions>
</plugin>

BrowserDriverHolder.java

private WebDriver createDriver(final String driverName, final String headless) {
    ChromeOptions options = new ChromeOptions();
    if (headless.toLowerCase().equals("true")) {
      options.addArguments("headless");
    }

    options.addArguments("debug");
    options.addArguments("no-sandbox");

    options.setBinary("/usr/bin/linux/googlechrome/64bit/chromedriver");
    System.setProperty("webdriver.chrome.driver", "/usr/bin/linux/googlechrome/64bit/chromedriver");
    options.addArguments("window-size=1920,1080");
    ChromeDriver driver = new ChromeDriver(options);

    driver.manage().window().maximize();
    driver.manage().timeouts().pageLoadTimeout(360, TimeUnit.SECONDS);
    driver.manage().timeouts().setScriptTimeout(360, TimeUnit.SECONDS);
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    return driver;
}

ECS容器成功启动并开始回归测试，并显示以下错误消息：

ChromeDriver正在运行并且正在侦听给定的端口。

我正在努力寻找解决方案，感谢您的帮助。

Answer 1

您计算机上的chromedriver版本和Google Chrome二进制文件之间很可能不匹配。

您的Maven插件似乎正在下载Chromedriver version 2.33
查看Chromedriver 2.33 release notes

支持Chrome v60-62

因此，您要么需要增加chromedriver版本，要么将Chrome的版本降级到60到62之间。

我还相信选项必须以2个破折号开头，例如：

options.addArguments("--headless")

如果您不能负担得起降级浏览器或升级驱动程序的费用，请考虑使用remote testing in Selenium cloud，到目前为止，支持的Chrome版本从43到67，其中包括60-62的子范围。
