WebDriver

WebDriver is a standardized interface to interact with web documents primarily intended for automated testing. Tauri supports the WebDriver interface by leveraging the native platform’s WebDriver server underneath a cross-platform wrapper tauri-driver.

System Dependencies

Install the latest tauri-driver or update an existing installation by running:

Terminal window
cargo install tauri-driver

Because we currently utilize the platform’s native WebDriver server, there are some requirements for running tauri-driver on supported platforms. Platform support is currently limited to Linux and Windows.

Linux

We use WebKitWebDriver on Linux platforms. Check if this binary exists already (command which WebKitWebDriver) as some distributions bundle it with the regular WebKit package. Other platforms may have a separate package for them, such as webkit2gtk-driver on Debian-based distributions.

Windows

Make sure to grab the version of Microsoft Edge Driver that matches your Windows Edge version that the application is being built and tested on. This should almost always be the latest stable version on up-to-date Windows installs. If the two versions do not match, you may experience your WebDriver testing suite hanging while trying to connect.

The download contains a binary called msedgedriver.exe. tauri-driver looks for that binary in the $PATH so make sure it’s either available on the path or use the --native-driver option on tauri-driver. You may want to download this automatically as part of the CI setup process to ensure the Edge, and Edge Driver versions stay in sync on Windows CI machines. A guide on how to do this may be added at a later date.

Example Applications

Below are step-by-step guides to show how to create a minimal example application that is tested with WebDriver.

If you prefer to see the result of the guide and look over a finished minimal codebase that utilizes it, you can look at https://github.com/chippers/hello_tauri.

Continuous Integration (CI)

The above examples also comes with a CI script to test with GitHub actions, but you may still be interested in the below WebDriver CI guide as it explains the concept a bit more.
