defmodule PlausibleWeb.TrackerPlugTest do
@moduledoc """
This test module uses auto-generated JavaScript tracker files in priv/tracker/js.
To speed up running Elixir tests locally, the tracker files are not automatically generated
with every `mix test` command. That means, you have to manually run the below command
once before executing `mix test`. This is to make sure all tracker files are in place and up to date.
```
npm run deploy --prefix tracker
```
If you're making changes in the tracker template files (`src/plausible.js`, `compile.js`),
do regenerate the files before running tests, so they're up to date.
