A set of Elixir helpers to set/get test selectors to/from elements in a Phoenix app (when Mix.env == :test
). These selectors are hashed (scoped to the view module they are used in) for accurate selection and "leakage" prevention. See our Wiki for examples.
Why? Because we prefer reserving classes for styling, and id's have limitations because they have to be unique.
- Floki v0.25.x and higher
def deps do
[
{:test_selector, "~> 0.3.2"}
]
end
Use TestSelector.HTML.Helpers
to your web.ex.
- In phoenix 1.2.0 at
web/web.ex
- In newer Phoenix versions
lib/your_project/web/web.ex
Add somewhere along:
def view(opts \\ []) do
quote do
...
use Phoenix.HTML
use TestSelector.HTML.Helpers
...
end
end
Testing with Floki
In the tests import the TestSelector.Test.FlokiHelpers
:
defmodule Project.Web.MyTest do
...
import TestSelector.Test.FlokiHelpers
...
end
Run the tests:
mix test
