[英]How to fix “Connection Refused” error while connecting with Selenium Docker Firefox container from Selenium RemoteWebDriver?
[英]Gitlab ci selenium testing with docker not connecting to RemoteWebDriver
我想用 gitlab-ci、docker 自動運行 selenium 測試。
在本地一切正常,但似乎 docker 和 selenium 存在一些連接問題。
工作失敗
selenium.test.dashboard.MyTest > myFirstTest FAILED
org.openqa.selenium.remote.UnreachableBrowserException
Caused by: java.net.ConnectException
Caused by: java.net.ConnectException
java.lang.NullPointerException
我嘗試更改不同的 url 以連接到 selenium 服務器,我認為可能存在端口問題。 但是我嘗試過的每種組合都得到了相同的結果。

RemoteWebDriver 的 Java 代碼
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 runner 上創建容器

docker 在 runner 上記錄命令

我確實希望測試在 docker 容器中的 gitlab-ci-runner 上運行。 連接到 selenium-server 並使用公共可用的 url 執行 selenium 測試
正如@Sascha Frinken所指出的
連接到RemoteWebDriver的URL錯誤。 我錯過了一個下划線。
“ http:// selenium_standalone-chrome:4444 / wd / hub ”
VS
gitlab https://docs.gitlab.com/ee/ci/services/#accessing-the-services 中有一個主題,其中指出
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).
