Continuous Integration

Utilizing Linux and some programs to create a fake display, it is possible to run WebDriver tests with tauri-driver on your CI. The following example uses the WebdriverIO example we previously built together and GitHub Actions.

This means the following assumptions:

1. The Tauri application is in the repository root and the binary builds when running cargo build --release.
2. The WebDriverIO test runner is in the webdriver/webdriverio directory and runs when yarn test is used in that directory.

The following is a commented GitHub Actions workflow file at .github/workflows/webdriver.yml

# 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`
