Specs

ensure_started(app(), restart_type()) :: :ok | {:error, term()}

Ensures the given app is started.

Same as start/2 but returns :ok if the application was already started. This is useful in scripts and in test setup, where test applications need to be explicitly started:

:ok = Application.ensure_started(:my_test_dep)
