TestSelector

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.

Dependencies

• Floki v0.25.x and higher

Installation

def deps do
  [
    {:test_selector, "~> 0.3.3"}
  ]
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

Tests

Run the tests:

mix test
