Gitlab ci selenium 测试 docker 未连接到 RemoteWebDriver

Question

我想运行使用 gitlab 自动进行 selenium 测试-ci, docker.

本地一切正常，但似乎 docker 和 selenium 存在一些连接问题。

作业失败

selenium.test.dashboard.MyTest > myFirstTest FAILED
    org.openqa.selenium.remote.UnreachableBrowserException
        Caused by: java.net.ConnectException
            Caused by: java.net.ConnectException
    java.lang.NullPointerException

我尝试更改不同的 url 以连接到 selenium 服务器，但我认为可能存在端口问题。但是我尝试过的每一种组合最终都得到了相同的结果。

.gitlab-ci.yml

image: gradle:alpine

variables:
  GRADLE_OPTS: "-Dorg.gradle.daemon=false"

before_script:
  - export GRADLE_USER_HOME=`pwd`/.gradle

stages:
  - build
  - seleniumTesting


build:
  stage: build
  script: 
    - echo $CI_JOB_STAGE
    - echo $CI_COMMIT_REF_NAME
    - gradle --build-cache war
  artifacts:
    paths:
      - public
  cache:
    key: "$CI_COMMIT_REF_NAME"
    policy: push
    paths:
      - build
      - .gradle


seleniumTestingChrome:

Java RemoteWebDriver 代码

DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.setBrowserName(DesiredCapabilities.chrome().getBrowserName());

            try {
//              driver = new RemoteWebDriver( new URL("http://selenium_standalone-chrome:4444/wd/hub"), capabilities);
                WebDriver driver = new RemoteWebDriver( new URL("http://127.0.0.1:4444/wd/hub"), capabilities);

            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

在运行ner

上创建容器

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES

docker 在运行ner

上记录命令

我确实希望测试在 docker 容器中的 gitlab-ci-运行ner 上运行ning。连接到 selenium-server 并使用 public 可用 url

执行 selenium 测试

Answer 1

正如@Sascha Frinken 指出的那样

连接到 RemoteWebDriver 的 URL 错误。我漏了一个下划线。

"http://selenium_standalone-chrome:4444/wd/hub"

VS

"http://selenium__standalone-chrome:4444/wd/hub"

Answer 2

gitlab 中有一个主题 https://docs.gitlab.com/ee/ci/services/#accessing-the-services，它指出

Everything after the colon (:) is stripped.
Slash (/) is replaced with double underscores (__) and the primary alias is created.
Slash (/) is replaced with a single dash (-) and the secondary alias is created (requires GitLab Runner v1.1.0 or higher).
