等待驱动程序服务器启动错误执行 Java 测试时超时 CI

Question

我才开始将 Circle CI 工具用于运行我的 Java 自动测试（Selenium、Maven）。

我的代码在Java:

    public void setUp() {
        WebDriverManager.chromedriver().setup();
        webDriver = new ChromeDriver(setOptions());
        webDriver.manage().window().maximize();
        webDriver.manage().timeouts().pageLoadTimeout(40, TimeUnit.SECONDS);
        webDriver. manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }

    public ChromeOptions setOptions() {
        ChromeOptions options = new ChromeOptions();
        options.setHeadless(true);
        options.addArguments("enable-automation");
        options.addArguments("--headless");
        options.addArguments("window-size=1024,768");
        options.addArguments("--disable-extensions");
        options.addArguments("--dns-prefetch-disable");
        options.addArguments("--disable-gpu");
        return options;
    }

我的config.yml在.circleci目录：

version: 2.1
jobs:
  build:
    docker:
      - image: cimg/node:16.13.1-browsers
    steps:
      - checkout
      - run: mkdir test-reports
      - run:
          name: Download Selenium
          command: curl -O http://selenium-release.storage.googleapis.com/3.5/selenium-server-standalone-3.5.3.jar
      - run:
          name: Start Selenium
          command: java -jar selenium-server-standalone-3.5.3.jar -log test-reports/selenium.log
          background: true
  test:
    docker:
      - image: cimg/openjdk:11.0
    steps:
      - checkout
      - run:
          name: build
          command: mvn -B -DskipTests clean package
      # Then run your tests!
      - run:
          name: test
          command: mvn test -Dtest=SignUp
      - store_test_results:
          path: target/surefire-reports
workflows:
  sample:
    jobs:
      - build
      - test

Build 作业已成功完成。但是 test 作业失败并出现下一个错误：

org.openqa.selenium.WebDriverException: 
Timed out waiting for driver server to start.
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'
System info: host: 'df35181eab7e', ip: '172.31.0.3', os.name: 'Linux', os.arch: 'amd64', os.version: '5.13.0-1017-aws', java.version: '11.0.13'
Driver info: driver.version: ChromeDriver
Caused by: org.openqa.selenium.net.UrlChecker$TimeoutException: Timed out waiting for [http://localhost:24652/status] to be available after 20001 ms
Caused by: java.util.concurrent.TimeoutException

请问如何解决这个问题？

Answer 1

这个错误信息...

org.openqa.selenium.WebDriverException: 
Timed out waiting for driver server to start.
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'

...表示驱动程序服务器未启动。

您需要注意以下几点：

config.yml文件在.circleci 目录提到 Selenium v3.5.3:

- run:
    name: Download Selenium
    command: curl -O http://selenium-release.storage.googleapis.com/3.5/selenium-server-standalone-3.5.3.jar

和

- run:
    name: Start Selenium
    command: java -jar selenium-server-standalone-3.5.3.jar -log test-reports/selenium.log

其中错误堆栈跟踪提到 Selenium v3.141.59:

Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'

您需要交叉检查 Circle CI 配置中的设置并解决问题。
