持續整合

利用 Linux 和一些程式建立一個虛擬顯示器，可以在 CI 上使用 WebDriver 測試，搭配 tauri-driver。以下範例使用 WebdriverIO 範例，我們 之前一起建立，以及 GitHub Actions。

這表示以下假設

1. Tauri 應用程式在儲存庫根目錄中，且在執行 cargo build --release 時會建置二進位檔。
2. WebDriverIO 測試執行器在 webdriver/webdriverio 目錄中，且在該目錄中使用 yarn test 時會執行。

以下是在 .github/workflows/webdriver.yml 中的註解 GitHub Actions 工作流程檔案

# run this action when the repository is pushed to
on: [push]

# the name of our workflow
name: WebDriver

jobs:
  # a single job named test
  test:
    # the display name of the test job
    name: WebDriverIO Test Runner

    # we want to run on the latest linux environment
    runs-on: ubuntu-latest

    # the steps our job runs **in order**
    steps:
      # checkout the code on the workflow runner
      - uses: actions/checkout@v2

      # install system dependencies that Tauri needs to compile on Linux.
      # note the extra dependencies for `tauri-driver` to run which are: `webkit2gtk-driver` and `xvfb`
      - name: Tauri dependencies
        run: >-
          sudo apt-get update &&
          sudo apt-get install -y

      # run the WebdriverIO test suite.
      # we run it through `xvfb-run` (the dependency we installed earlier) to have a fake
      # display server which allows our application to run headless without any changes to the code
