[英]How to handle redirects in Wallaby?
I have a feature test written like this:我有一个这样写的功能测试:
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:但是测试总是失败,因为在 controller 中,单击此页面时,我正在这样做:
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.所以 flash 出现在重定向页面上,而不是原始页面上。 How can I wait for the redirect and assert on the new page?我如何等待重定向并在新页面上断言?
You can simply provide a sleep timer like :time.sleep(1000)
before asserting over element.在断言元素之前,您可以简单地提供一个睡眠计时器,如:time.sleep(1000)
。
You can retry like waiting for page to be refreshed.您可以像等待页面刷新一样重试。 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
.您可以使用Wallaby.retry/2
重试,直到 window 在特定 url 上刷新。我们可以使用Wallaby.current_url/1
获取 window 的当前 url。 Code would look something like this.代码看起来像这样。
1 retry = fn -> if Wallaby.current_url == "expected" do
2 ┆ ┆ ┆ assert_text(confirmation_page)
3 ┆ ┆ ┆ else
4 ┆ ┆ ┆ {:error, :url_not_refreshed}
5 ┆ ┆ ┆end
6 ┆ end
7
8 assert {:ok, response} = Wallaby.retry(retry, 5000) ## default timeout option after which it
Try to use assert_has(session, css("element ID or class", text: "You have declined."))
尝试使用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.断言已内置重试,因此它将等待此元素出现,因此我认为它会解决您的问题。
