Question

问题陈述：云上有一个linux vm，我们用于运行回归测试（测试源代码位于vm中），因此我们只需要创建一个安装了网格的docker容器，然后调用mvn clean test在网格上运行测试

我尝试了两种不同的方法来解决这个问题

1）将所有源和依赖项构建到jar中，使用卷映射将其复制到容器中，然后使用

运行

 java -cp websiteautomation-1.0.jar:websiteautomation-1.0-tests.jar:libs/* -Dcucumber.options=classpath:features org.junit.runnner.JUnitCore runner.CucumberRunner

我每次都用这种方法运行的问题是

Error: Could not find or load main class org.junit.runnner.JUnitCore

Caused by: java.lang.ClassNotFoundException: org.junit.runnner.JUnitCore

调试步骤：

我检查是否在所有依赖项，源和lib所在的正确目标文件夹中，打开了libs文件夹，发现其中有junit-4.12.jar

2）我尝试了另一种方法，因为我的项目文件已经在虚拟机中了

在虚拟机上创建硒集线器网格

在我正在创建的容器中创建一个工作目录

将其映射到我的pom.xml所在的项目目录

运行maven命令以运行测试

mvn clean  test -Dtest=CucumberRunner -Dbrowser.name=chrome -Denv.type=uat

我使用这种方法遇到的问题是（下面的错误摘要）

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

        tests_1 | at okhttp3.internal.connection.RealConnection.connectSocket(RealConnection.java:247)


Caused by: java.net.ConnectException: Connection refused (Connection refused)

调试步骤：

1）网格正在运行，maven正在下载我的依赖项，开始测试并抛出以上错误，找不到我的网格

2）检查我的远程驱动程序设置是否正确

Platform platform = Platform.fromString(os.toUpperCase());
else if(os.contains("linux")) {
    System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + "/drivers/chrome/chromedriver_linux");
    ChromeOptions options = new ChromeOptions();
    options.setCapability("platform", platform);
    options.addArguments("--kiosk");
    driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),options);
    break;

}

3）验证了我的HUB，chrome和firefox，硒是否兼容版本

我还将共享我的Dockerfile，docker-compose文件和pom.xml

我需要另一双眼睛，如果您能找出问题所在，将会非常有帮助，我现在很着迷于修复此问题并使它正常工作
