美好的一天！可以在没有互联网访问的情况下使用测试容器吗？我下载了所需的容器。他们启动并运行。在这种情况下，运行测试时会发生错误。我无法上网

代码

container = new BrowserWebDriverContainer<>().withCapabilities(Capabilities.getFirefoxOptions()).withRecordingMode(
          webDriverForm.get().isVideoError() ? VncRecordingMode.RECORD_FAILING : VncRecordingMode.RECORD_ALL,
          new File(webDriverForm.get().getVideoPath()), VncRecordingFormat.MP4);

ontainer.start();
WebDriver driver = container.getWebDriver();

错误

只有保存的容器才能在 docker 中运行。

如果您的网络无法访问互联网，您必须设置自己的 docker hub。您必须通过以下方式上传 docker 容器：

docker tag
docker push

命令
