GitHub Actions で Windows IE11 と Mac Safari を selenium-webdriver で動かす

最近得た天啓で、 「GitHub Actions はコンテナを windows / mac / ubuntu から選べるということは、 本物の safari と ie11 を selenium-webdriver で動かすことができるのでは?」 と思ってガチャガチャやってみたら、なんとできてしまったので、紹介します。

今回は node で。

npm install selenium-webdriver --save-dev
.github/workflows/xbrowser.yaml
name: xbrowser

on: [push]

jobs:
  e2e-ie:
    runs-on: windows-latest
    steps:
      - uses: actions/checkout@v1
      - uses: warrenbuckley/Setup-Nuget@v1
      - uses: actions/setup-node@v1
        with:
          node-version: 12
      - run: yarn install
      - run: nuget install Selenium.WebDriver.IEDriver -Version 3.150.0
      - run: node scratch.js
        env:
          BROWSER: ie
  e2e-safari:
    runs-on: macos-latest
    steps:
      - uses: actions/checkout@v1
      - uses: actions/setup-node@v1
        with:
          node-version: 12
      - run: yarn install
      - name: Run safari driver
        run: |
          sudo safaridriver --enable
          safaridriver -p 0 &
      - run: node scratch.js
        env:
          BROWSER: safari

今回動かしてるスクリプト。 youtube にアクセスして、title を取得するだけ。

scratch.js
const webdriver = require("selenium-webdriver");

function buildCapabilities() {
  switch (process.env.BROWSER) {
    case "ie": {
      process.env.PATH = `${process.env.PATH};${__dirname}/Selenium.WebDriver.IEDriver.3.150.0/driver/;`;
      const capabilities = webdriver.Capabilities.ie();
      capabilities.set("ignoreProtectedModeSettings", true);
      capabilities.set("ignoreZoomSetting", true);
      return capabilities;
    }
    case "safari": {
      return webdriver.Capabilities.safari();
    }
  }
}

async function main() {
  let driver;
  try {
    const capabilities = await buildCapabilities();
    driver = await new webdriver.Builder()
      .withCapabilities(capabilities)
      .build();

    await driver.get("https://www.youtube.com/");
    const title = await driver.getTitle();
    console.log("title", title);
  } catch (e) {
    console.error(e);
    process.exit(1);
  }
  driver && (await driver.quit());
}

main();

パスの書き換えのところがちょっと Hacky なんですが、もっときれいに書けるかも

これが動いてる風景

感想

えっこれ最高では。

(もうちょっと頑張れば Android Chrome と iOS Emulator も動かせる気がする…)
