Wallaby is an Elixir library for concurrent end-to-end browser testing of web applications, simulating realistic user interactions. It manages browser sessions (via ChromeDriver or Selenium) and integrates with ExUnit so tests run asynchronously in parallel.

Use cases

• run concurrent browser tests for a Phoenix app
• simulate user interactions like filling forms and clicking buttons in E2E tests
• test multiple users interacting with a page simultaneously
• write feature tests with ExUnit async support
• test web apps with ChromeDriver or Selenium

When to choose

• you're building Elixir/Phoenix web apps and need automated browser tests
• you want fast, parallel test execution with automatic browser management
• you need to test real-time multi-user interactions in the browser

When to avoid

• you're testing non-Elixir web applications
• you only need unit or integration tests without a real browser
• you need a JavaScript-first testing tool like Playwright or Cypress
