I have a feature test written like this:

confirmation_page = visit(session, "/confirm/#{id}")
confirmation_page
    |> click(link("Decline"))
confirmation_page
    |> assert_text("You have declined.")

However the test always fails, because in controller, on click of this page, I am doing this:

 conn
    |> put_flash(:info, "You have declined.")
    |> redirect(to: Routes.group_path(conn, :show, group.slug))

So the flash is coming on the redirected page, and not the original page. How can I wait for the redirect and assert on the new page?

  1. You can simply provide a sleep timer like :time.sleep(1000) before asserting over element.

  2. You can retry like waiting for page to be refreshed. You can use Wallaby.retry/2 to retry until window is refreshed on specific url. We can get current url of window using Wallaby.current_url/1. Code would look something like this.

1 retry = fn -> if Wallaby.current_url == "expected" do

  • It didn't work. The weird part is that same test is succeeding in someone else's machine with same `chrome` and `chromedriver` version. – Ryosuke Aug 11 '20 at 20:05

Try to use assert_has(session, css("element ID or class", text: "You have declined."))

The assert has have build in retry so it will wait for this element to show up so I think it will solve your problem.
