I need to open a separate window from a link in my main page and leave the main opened. I am using the following code to do so:

self.find_element_by_locator(locator="css==a[href='#/vehicles']").send_keys(Keys.CONTROL + Keys.RETURN)

Then I need to do some stuff in the new window, so I try to switch the focus to it:

windows = self.driver.window_handles

Problem: - The window opens correctly but the focus remains on the main window. (in this case, the Error is that the index is out of range) When I make a Breakpoint and look into the windows I see there is only one element in the list, which refers to the main page and the new page doesn't appear. I also tried opening a new Tab (sending keys Control 't' and then sending keys CONTROL TAB) but the problem remains (The window handles only sees one page or tab)

There is a similar Question but even the implicit_wait doesn't help.

I saw many people having the same problem, but still can't find an answer. Do I have to create a completely other WebDriver or is there easier ways to resolve this problem?

I'm working on Windows10 64Bit / Selenium 3.4.3 / Python 3 and IE11 (IEDriverServer_x64_3.4.0)

  • What about other browsers, does the exact same test pass in other browsers - Chrome, Firefox?

  • I can't really say. I need it to run on IE since it's required by the project. Jul 31 '17 at 16:32
  • I am just trying to isolate the issue..trying to see if it is browser-specific.

  • Was there any progress with this? I am also sometimes experiencing this. Selenium+Java on IE11 and Chrome. Is it a Selenium issue? Intermittently failing to switch to a new tab or window.

In my case, before switch to the new window, a simply thread sleep make thing done.


# switch to new window

Can try this: Before you switch to a newly open tab, try to wait for a while, e.g.

WebDriverWait(browser, 5).until(EC.number_of_windows_to_be(2))

The number 2 if you're open the second tabs ;3 if you're switching to that third tabs

But I'm not really sure.

Correct me if I'm wronged

Hope it helps
