我需要在Docker容器中执行Selenium测试。我知道Selenium提供了集线器和节点容器，但是我必须编写自己的Dockerfile来构建一个容器，该容器将在没有网格配置的情况下执行测试。基本上，由于某种原因我不能使用网格。我已经写了一个Dockerfile。它在构建阶段通过。但是，当我运行容器时，它不会实例化浏览器并引发java.lang.IllegalStateException异常：驱动程序可执行文件不存在：/ home / automation / myproject

另外，请注意，我需要以无头模式执行测试，因此myproject中已经存在用于以无头模式运行浏览器的配置。

我尝试将+ rwx权限授予我下载和解压缩文件的位置。

在下面查看我的Dockerfile：

LABEL name="myproject" \
            author="TAFSEER HAIDER" \
            version="1.0" \

答案 0 :(得分：0)

您的代码似乎期望在/home/automation/myproject上找到geckodriver和chromedriver。

查看您的Dockerfile，您尚未在任何地方安装CromeDriver，而Geckodriver位于/home/automation/myproject/src/test/resources/webdrivers/selenium_standalone_binaries/linux/marionette/64bit

如果您打印出ENV变量的值，这将很有用：

  • webdriver.chrome.driver
  • webdriver.gecko.driver

然后我们可以100％确定您的代码期望在哪里找到驱动程序二进制文件，然后可以检查它们实际在那里存在。
