Wallaby
Concurrent browser tests for your Elixir web apps
...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.
