使用硒和Firefox运行gitlab CI，获取WebDriverRorr：流程意外关闭，状态1

Question

我需要设置一个简单的CI配置来运行Web应用程序项目的测试。 ，我的测试文件看起来像这样：

import { promises as fsp } from "fs";
import { equal } from "assert";
import {
  Builder,
  Capabilities,
  // eslint-disable-next-line node/no-unpublished-import
} from "selenium-webdriver";

/* global describe, it, after */

async function takeScreenshot(driver, file) {
  const image = await driver.takeScreenshot();
  await fsp.writeFile(file, image, "base64");
}

describe("Selenium test", () => {
  const driver = new Builder().withCapabilities(Capabilities.firefox()).build();

  it("should go to google.com and check title", async () => {
    await driver.get("https://www.google.com");
    await takeScreenshot(driver, "test.png");
    const title = await driver.getTitle();
    equal(title, "Google");
  });

  after(() => driver.quit());
});

我正在使用以下CI配置

image: ubuntu

test:
  script:
    - apt update
    - apt install -y firefox npm xvfb
    - npm install
    - npm run lint
    - xvfb-run npm run test

当前 问题。

所有这些都会产生以下错误：

$ xvfb-run npm run test
> [email protected] test
> node ./node_modules/mocha/bin/mocha --exit --timeout 10000
  Selenium test
    1) should go to google.com and check title
    2) "after all" hook for "should go to google.com and check title"
  0 passing (303ms)
  2 failing
  1) Selenium test
       should go to google.com and check title:

  2) Selenium test
       "after all" hook for "should go to google.com and check title":
     WebDriverError: Process unexpectedly closed with status 1

      at processTicksAndRejections (internal/process/task_queues.js:97:5)
Cleaning up project directory and file based variables
ERROR: Job failed: exit code 1

我不知道我该怎么办来解决这个问题。我没有附上当前的配置，实际上我认为使用Ubuntu映像可能是浪费，但其他事情也对我有用。如果某人具有完全不同的配置，该配置将与随附的测试文件一起使用，那么我很乐意采用它。

Answer 1

我认为您没有安装geckodriver。我在运行Chromium和Firefox的同时遇到了相同的问题，以及selenium。 Chromium有Chromedriver依赖性，因此我没有问题。同时，firefox没有geckodriver依赖关系。

因此，请只需安装geckodriver即可。

PS I可以提供准备硒选项的完整解决方案：

const builder = new Builder().forBrowser(Browser.FIREFOX);

const firefoxOptions = new Firefox.Options();
const testBrowserPath = await which(TEST_BROWSER_NAME);
firefoxOptions.setBinary(testBrowserPath);
firefoxOptions.addArguments(...TEST_BROWSER_SELENIUM_ARGUMENTS);
builder.setFirefoxOptions(firefoxOptions);

const testBrowserDriverPath = await which(TEST_BROWSER_DRIVER_NAME);
const firefoxServiceBuilder = new Firefox.ServiceBuilder(testBrowserDriverPath);
builder.setFirefoxService(firefoxServiceBuilder);

const webDriver = await builder.build();

哪里：

export const TEST_BROWSER_NAME = 'firefox';
export const TEST_BROWSER_SELENIUM_ARGUMENTS = ['--headless'];
export const TEST_BROWSER_DRIVER_NAME = 'geckodriver';
