这对我来说是靠 cap巴网做的:

within_window(windows.last) do
  # code here
end

(一米,使用帽子2.4.1和帽子13.0)

You can pass a name, url or title of the window also (But now its dipricated)

  let(:product) { create :product }

  it  tests  do
    visit products_path
    click_link(product.id)

    within_window(product_path(product)) do
      expect(page).to have_content(product.title)
    end
  end

页: 1 并且

within_window(->{ page.title ==  Page title  }) do
  click_button  Submit 
end

希望它把方法的使用延伸到更为明显的障碍

I had this issue when opening links in an gmail window: I fixed it like this:

Given /^(?:|I )click the "([^"]*)" link in email message$/ do |field|

  # var alllinks = document.getElementsByTagName("a");
  # for (alllinksi=0; alllinksi<alllinks.length; alllinksi++) {
  #   alllinks[alllinksi].removeAttribute("target");
  # }

  page.execute_script( var alllinks = document.getElementsByTagName("a"); for (alllinksi=0; alllinksi<alllinks.length; alllinksi++) { alllinks[alllinksi].removeAttribute("target"); } )

  within(:css, "div.msg") do
    click_link link_text
  end

end

The best idea is to update capybara to the latests version (2.4.1) and just use windows.last because page.driver.browser.window_handles is deprecated.

主要实施(window_ opened_by)给我带来了错误:

*** Capybara::WindowError Exception: block passed to #window_opened_by opened 0 windows instead of 1

因此,我通过这一解决办法解决这个问题:

new_window = open_new_window

within_window new_window do
  visit(click_link  Something )
end

page.driver.browser.window_handles
# => ["CDwindow-F7EF6D3C12B68D6B6A3DFC69C2790718", "CDwindow-9A026DEC65C3C031AF7D2BA12F28ADC7"]

I personally like the following approach since it works correctly regardless of JS being enabled or not.

My Spec:

  it "shows as expected" do
    visit my_path

    # ...test my non-JS stuff in the current tab

    switch_to_new_tab

    # ...test my non-JS stuff in the new tab
    
    # ...keep switching to new tabs as much as necessary
  end 

  # OR

  it "shows as expected", js: true do
    visit my_path

    # ...test my non-JS stuff in the current tab
    # ...also test my JS stuff in the current tab

    switch_to_new_tab

    # ...test my non-JS stuff in the new tab
    # ...also test my JS stuff in the new tab

    # ...keep switching to new tabs as much as necessary
  end 

测试助手:

  def switch_to_new_tab
    current_browser = page.driver.browser

    if js_enabled?
      current_browser.switch_to.window(current_browser.window_handles.last)
    else
      visit current_browser.last_request.fullpath
    end
  end

  def js_enabled?
    Capybara.current_driver == Capybara.javascript_driver
  end
