Wallaby can't find chromedriver even if it's installed

[jaeyson]

Hi! I'm having issue with wallaby not able to find chromedriver:

** (MatchError) no match of right hand side value: {:error, {:wallaby, {:bad_return, {{Wallaby, :start, [:normal, []]}, {:EXIT, 
{%Wallaby.DependencyError{message: "Wallaby can't find Chrome. Make sure you have chrome installed and included in your 
path.\nYou can also provide a path using `config :wallaby, :chromedriver, binary: <path>`.\n"}, [{Wallaby, :start, 2, [file: 
'lib/wallaby.ex', line: 33, error_info: %{module: Exception}]}, {:application_master, :start_it_old, 4, [file: 'application_master.erl', line:

• Elixir v1.14 (asdf: 1.14.0-otp-24)
• Wallaby v0.30.1
• (via brew) ChromeDriver 108.0.5359.71 (1e0e3868ee06e91ad636a874420e3ca3ae3756ac-refs/branch-heads/5359@{#1016})
• running which chromedriver shows /opt/homebrew/bin/chromedriver

the test file:

defmodule AppWeb.LiveTitleTest do
  use ExUnit.Case, async: false
  use Wallaby.Feature

  alias Wallaby.Query

  setup do
    product = App.ProductFixtures.product_fixture(%{}, :featured)

    %{
      default_prefix: App.app_name(),
      title: product.title,
      suffix_title: " | some description"
    }
  end

  feature "change to image title when popup appears", %{
    title: title,
    session: session,
    suffix_title: suffix_title
  } do
    page_title = title <> suffix_title

    session
    |> visit("/")
    |> assert_has(Query.css("a[phx-click=show_images]"))
    |> click(Query.css("a[phx-click=show_images]"))

    assert page_title(session) === page_title
  end
end

# ExUnit.configure(exclude: :feature)
ExUnit.start()

{:ok, _} = Application.ensure_all_started(:wallaby)
Application.put_env(:wallaby, :base_url, AppWeb.Endpoint.url())

endpoint.exs

defmodule AppWeb.Endpoint do
  use Phoenix.Endpoint, otp_app: :app

  if sandbox = Application.get_env(:app, :sandbox) do
    plug Phoenix.Ecto.SQL.Sandbox, sandbox: sandbox
  end
...

config/test.exs

config :app, AppWeb.Endpoint,
  server: true
  
config :wallaby, otp_app: :app
config :app, :sandbox, Ecto.Adapters.SQL.Sandbox

I don't understand why commenting {:ok, _} = Application.ensure_all_started(:wallaby) didn't throw error.

There error is saying it can't find Chrome, not chromedriver.

Do you have Google Chrome installed?
