Multiple sessions

Each session runs in its own browser so that each test runs in isolation. Because of this isolation multiple sessions can be created for a test:

@message_field Query.text_field("Share Message")
@share_button Query.button("Share")
@message_list Query.css(".messages")

test "That multiple sessions work" do
  {:ok, user1} = Wallaby.start_session
  user1
  |> visit("/page.html")
  |> fill_in(@message_field, with: "Hello there!")
  |> click(@share_button)

  {:ok, user2} = Wallaby.start_session
  user2
  |> visit("/page.html")
  |> fill_in(@message_field, with: "Hello yourself")
  |> click(@share_button)

  assert user1 |> find(@message_list) |> List.last |> text == "Hello yourself"
  assert user2 |> find(@message_list) |> List.first |> text == "Hello there"
end
