Open Source Elixir Browsers

Hound is an Elixir library for browser automation and integration testing. It wraps the WebDriver protocol, allowing developers to write ExUnit tests that control browsers like Firefox, Chrome, or PhantomJS via Selenium or ChromeDriver. Hound supports parallel sessions, asynchronous test execution, JavaScript-heavy interactions, screenshots, and more—all directly in Elixir test suites.

Wallaby helps you test your web applications by simulating realistic user interactions. By default, it runs each test case concurrently and manages browsers for you. Here's an example test for a simple Todo application. Because Wallaby manages multiple browsers for you, it's possible to test several users interacting with a page simultaneously. Read on to see what else Wallaby can do or check out the Official Documentation. Wallaby also requires bash to be installed. Generally, bash is widely available, but it does not come pre-installed on Alpine Linux. If you're testing a Phoenix application with Ecto and a database that supports sandbox mode, you can enable concurrent testing by adding the Phoenix.Ecto.SQL.Sandbox plug to your Endpoint. It's important that this is at the top of endpoint.ex before any other plugs.
