Is there a way to close a tab in WebDriver or Prot

问题:

Is there a way to physically close a tab via Protractor or WebDriver?

I ask because while I know how to switch tabs programmatically, but it does not bring the active tab to the foreground. I can't always tell what is going on in my E2E tests that run on SauceLabs because when I view the screen casts it is showing the tab that I navigated away from, not the active one.

Am I going about this incorrectly?

it('should do something in the previous tab', function(done) {
    browser.getAllWindowHandles().then(function (handles) {
        browser.switchTo().window(handles[0]);
        // do something
        expect(something).toEqual(thisThing);
        done();
    });
});

回答1:

You can try the following:

Switch to the new opened tab. Close the current windows (in this case, the new tab). Switch back to the first window.

browser.getAllWindowHandles().then(function (handles) {
    browser.driver.switchTo().window(handles[1]);
    browser.driver.close();
    browser.driver.switchTo().window(handles[0]);
});

First of all, selenium does not provide a reliable cross-browser API to work with browser tabs. A common approach to open or close a tab (although not quite reliable) is to invoke browser shortcuts for Chrome:

• open tab: CTRL/COMMAND + T
• close tab: CTRL/COMMAND + W

In protractor, find the body element and "send keys" to it:

var body = element(by.tagName("body"));
body.sendKeys(protractor.Key.chord(protractor.Key.CONTROL, "t"))
body.sendKeys(protractor.Key.chord(protractor.Key.CONTROL, "w"))

Or, using browser.actions():

browser.actions().keyDown(protractor.Key.CONTROL).sendKeys('t').perform();
browser.actions().keyDown(protractor.Key.CONTROL).sendKeys('w').perform();

Also, to open a new tab, there is an interesting hack (introduced here), which basically injects a new a element into the page and invokes click mouse event:

function openNewTab (url) {
    return browser.driver.executeScript(function(url) {(
        function(a, url){
            document.body.appendChild(a);
            a.setAttribute('href', url);
            a.dispatchEvent((function(e){
                e.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, false, 0, null);
                return e;
            }(document.createEvent('MouseEvents'))))
        }(document.createElement('a'), url)
    );
    }, url)
};

There is also window.close() function, but it would not close the tab if it was not opened via window.open() (reference). In other words, if this is a tab you manually open, then you can use window.open() -> window.close() approach with the help of browser.executeScript().

C# Version of Sakshi's answer:

   var tabs = driver.WindowHandles;
   if (tabs.Count > 1)
   {
       driver.SwitchTo().Window(tabs[1]);
       driver.Close();
       driver.SwitchTo().Window(tabs[0]);
   }

Close all tabs except first one and switch to first tab:

var tabs = driver.WindowHandles; // 

foreach (var tab in tabs)
{
     // "tab" is a string like "CDwindow-6E793DA3E15E2AB5D6AE36A05344C68"
     if (tabs[0] != tab) 
     {                                    
         driver.SwitchTo().Window(tab); 
         driver.Close();
     }
}

driver.SwitchTab(tabs[0]); // Switch to first tab
driver.SwitchTo().DefaultContent(); // Switch to default frame

Pay attention to last two lines, they are need to avoid such errors like OpenQA.Selenium.NoSuchWindowException: no such window: target window already closed from unknown error: web view not found

回答5:

You can use driver.close and then switch to active tab driver.SwitchTo().Window(m_driver.WindowHandles.First()); or any another available tab

回答6:

I am using the command below to close the current tab after opening the link in new tab

Instance.Driver2.SwitchTo().Window(Instance.Driver2.WindowHandles[1]).Close();

Then, you can switch to the last tab by issue the command:

Instance.Driver2.SwitchTo().Window(Instance.Driver2.WindowHandles[0]);
