I'm having difficulty testing a piece of code using NightwatchJS with Selenium and SafariDriver.
I have an open issue for this on nightwatch repo, although am not sure if it is an issue with nightwatch or something deeper.
The HTML content to be tested looks something like:
<body>
<iframe id="top-iframe" src="about:blank">
#document
<html>
<body>
<container>
<!-- access this iframe to test -->
<iframe id="nested-iframe" src="news.google.com"></iframe>
</container>
</body>
</html>
</iframe>
</body>
Where #nested-frame will need to be accessed from the top level document for inspection of content.
The test code is using NightwatchJS, more details about config, setup and code are in the GitHub issue.
The Gist of the issue:
The problem is that to access the nested iFrame, it needs to first find #top-frame web element, use the returned web element and pass it to frame which makes the WebDriver call to change context of test session to that frame. This is all good with Chrome, FF, and Safari as they can all find this frame web element and make the switch into the frame context. My test that Safari was changing iFrame context, although not sure how good it is, was to try and find another DOM element other than the nested frame, which it could find. The problem comes when with Safari, after switching into #top-frame, it cannot find the #nested-frame web element, and Nightwatch returns a 404 no such element from the HTTP call. Strange, right?
It is very puzzling, my latest thinking was maybe it was a cross origin issue. But then I read on WebDriver switch to frame:
NOTE WebDriver is not bound by the same origin policy, so it is always possible to switch into child browsing contexts, even if they are different origin to the current browsing context.
And I also tried checking Disable Cross Origin Restrictions from Safari Developer menu.
As mentioned before, I can find another DOM element in the #top-frame. I tried things like 10-15s timeouts thinking maybe it needed to load. I can inspect the browser with debugger and see that #nested-frame is there and the content loads as expected. There are not console errors indicating any content failed to load.
It's very puzzling to me and I'm not sure how to further debug. Maybe someone else with a fresh perspective could have a suggestion or if someone has run into a similar situation as this. Throwing this out into the universe as information is limited on the topic too, so maybe this could help someone else. TIA!
iframes
As per the documentation iframe is a construct which embeds a document into an HTML document so that embedded data is displayed inside a subwindow of the browser's window. This does not mean full inclusion and the two documents are independent, and both them are treated as complete documents, instead of treating one as part of the other.
iframe structure and details
Generally, an iframe element is in the form of:
<iframe src="URL" more attributes>
alternative content for browsers which do not
support iframe
</iframe>
Browsers which support iframe display the document referred to by the URL in a subwindow, typically with vertical and/or horizontal scroll bars. Such browsers ignore the content of the iframe element (i.e. everything between the start tag <iframe...> and the end tag </iframe>). Browsers which do not support iframe (or have such support disabled) does the opposite, i.e. process the content as if the <iframe...> and </iframe> tags were not there. Thus, the content matters, despite being ignored by some browsers.
This usecase
As the top-level <iframe> is having src="about:blank" it is highly unlikely there can be any child <iframe>. Hence, in absence of any child <iframe> your attempt to access any nested <iframe> will fail.

After discussion with Selenium team, this appears to be a bug with Apple.
I have filed a ticket with Apple here.

I am trying to automate Salesforce application Using Selenium and getting NoSuchelementException though XPATH is correct and valid for particular object. When i have searched the issue, it might be reason for Shadow DOM.
For EX:
So XAPTH i have written like,
driver.findElement(By.xpath("//input[#name='Name']")).sendKeys("Jams");
or
driver.findElement(By.xpath("//input[#id='input-299']")).sendKeys("Jams");
This XPATH is highlighting in Console as well. But while automating it throws nosuchelement error.
So while checking for ShadowDOM option, am getting option like this for Name Object.
#shadow-root(user-agent)
Shadowroot DIV
-- nothing mentioned in div. it just open and closed tags.
How to automate this?
You can check if there are any iframes in your Dom. Simply do //iframe in your page developer mode(F12)> elements tab > search (Ctrf+F) area. If there are any, you will get the number of iframes.
Now if your textbox is in any of iframe use below code to go inside particular iframe first
driver.switch_to.frame("<name or Id of frame>")
then come out to frame use below:
driver.switch_to.parent_frame()
Also, if the issue is not related to frames check below for shadow-root related issue:
you can check below for shadow-root element ( Question is for Java, but you can co-relate):

The website contents are mostly created now using javascript. You may have to wait for certain elements to load before doing anything to it.

For the portal I am testing now, I came with the problem that I could not create any xpath locators, after some time I figured out that it was because of an '#document', this cuts the path and makes the simple "copy xpath" to direct the path to a completely different element.
<iframe id="FRAMENAME" src="/webclient/workspace/launch-task/REMbl?ds=BP" width="100%" height="100%" frameborder="0" data-navitemname="navitemname" style="" xpath="1">
#document
<html>
CODE....
</html>
I found the solution for this is it is simply add a switchTo like this:
driver.switchTo().frame("FRAMENAME");
This works and makes the rest of the code to work properly but, takes some extra time processing this command till the code moves to the next line.
So I would like to ask, is there is a better solution for this? something smarter/faster?
I am concerned that when the point where I have lots of scripts comes, the execution time will take too long.
I don't use id locators for example because they are all dynamic so sometimes a xpath is required.
Thank you!
To work with elements inside iframe you must switch to this specific iframe.
Your solution .switchTo().frame("FRAMENAME"); is correct. Selenium does not have any other ways to work with iframe wrappers.
inline frames
As per the documentation in Using inline frames, an inline frame is a construct which embeds a document into an HTML document so that embedded data is displayed inside a subwindow of the browser's window. This does not mean full inclusion and the two documents are independent, and both them are treated as complete documents, instead of treating one as part of the other.
iframe structure and details
Generally, an iframe element is in the form of:
<iframe src="URL" more attributes>
alternative content for browsers which do not
support iframe
</iframe>
Browsers which support iframe display the document referred to by the URL in a subwindow, typically with vertical and/or horizontal scroll bars. Such browsers ignore the content of the iframe element (i.e. everything between the start tag <iframe...> and the end tag </iframe>). Browsers which do not support iframe (or have such support disabled) does the opposite, i.e. process the content as if the <iframe...> and </iframe> tags were not there. Thus, the content matters, despite being ignored by some browsers.
So to summarize, inline frames do not mean an include feature, although it might sometimes serve similar purposes.
Note that, when inline frames are used, the browser (if it supports them) sends a request to the server referred to by the URL in the iframe element, and after getting the requested document displays it inside an inline frame. In this sense inline frames are a joint browser-server issue, but only the browser needs to be specifically iframe-aware; from the server's point of view, there's just a normal HTTP request for a document, and it sends the document without having (or needing) any idea on what the browser is going to do with it.
Something Smarter
As per the best practices while switching to an iframe you need to induce WebDriverWait as follows:
Switch through Frame Name (Java Sample Code):
new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("frame_name")));
Switch through iframe XPath (Python Sample Code):
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[#id='ptifrmtgtframe' and #name='TargetContent']")))
Switch through iframe CssSelector (C# Sample Code):
new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(By.CssSelector("iframe#twitter-widget-0")));

Having difficulty with Karate Driver and inputing data into fields that are in an iframe
Have tried using xpath and css selectors to the iframe so I could theoretically switch into and interact with the iframe without any luck. I can find the iframe but I am unsure how to switch context to the iframe so the scenario can continue inside the iframe. For example inputting values into fields in the iframe.
Help Please :)
Update:
Can successfully switch into an iframe but now running into an issue with nested iframe.
* switchFrame(0)
* click('.some-checkbox')
* switchFrame(0)
neither iframe has great css selectors. The second switchFrame with an index of 0 is not looking to the nested iframe.
I guess you have seen the docs here: https://github.com/intuit/karate/tree/develop/karate-core#switchFrame
I admit this is very tricky. Ideally you have a proper CSS or ID selector to the frame and this is an actual working example from a test I have. Note that the waitFor() may be what you are missing, especially when the <iframe> is some slow loading bloatware.
* waitFor('.some-css-name iframe').switchFrame()
* click('.some-checkbox')
* switchFrame(null)
And unfortunately I have found that this tends to work best on driver type: chrome and chromedriver
I am getting Cannot locate an element using By.xpath error in Selenium using Java(IE11). I am working on a web page created using Adobe AEM(CQ5).
I have tried the following possible solutions but neither of it helped.
Tried to add wait.
Switch to active window.
Tried even on Chrome.
Bring focus on element.
Currently using the absolute path (/html/body/div[4]/header[1]/div[1]/div[2]/div[5]/div[1]/nav/ul[1]/li[3]/a) but also used relative path (.//*[#id='cq-gen188']/nav/ul/li[3]/a).
Also searched whether there is any iframe involved. Unfortunately there was none.
To find the xpath, I have used FirePath plugin in Firefox. When i search for the element using the xpath in Firefox, i am successful. But when i execute the code i get the error.
If you are in the correct IFRAME then you can use
driver.findElement(By.id("cq-gen188"));
Remember that ID is always unique and that's a core assumption for all of the libraries in the authoring UI whether it is from core AEM framework or from custom components.
Your problem may be due to incorrect IFRAME as AEM neatly makes the UI look like a seamless window but there are IFRAME in place to facilitate various authoring navigation experiences.
I'm working in selenium with Firefox browser.
The Html code shown in View Source (CTRL+U) is different from the html code i see when inspecting the elements in Firefox.
When i run the driver.getPageSource() i only get the View source (CTRL + U) codes.
Is there is any way to access the Inspect element code instead of View source code?
I think your question is answered here.
The View Source html is what is sent by the server. I think of it as compile time html, or the initial state of the DOM.
The Inspect Element html could have been updated by ajax responses or javascript so will not necessarily be the same. I think of it as runtime html, or the current state of the DOM.
The GetAttribute() method queries the current DOM element state. You can return a particular html attribute value directly
webElement.GetAttribute("class")
or get the whole html string.
webElement.GetAttribute("innerHTML")
There are some fundamental difference between the markup shown through View Source i.e. using ctrl + U and the markup shown through Inspector i.e. using ctrl + shift + I.
Both the methods are two different browser features which allows users to look at the HTML of the webpage. However, the main difference is the View Source shows the HTML that was delivered from the web server (application server) to the browser. Where as, Inspect element is a Developer Tool e.g. Chrome DevTools to look at the state of the DOM Tree after the browser has applied its error correction and after any Javascript have manipulated the DOM. Some of those activities may include:
HTML error correction by the browser
HTML normalization by the browser
DOM manipulation by Javascript
In short, using View Source you will observe the Javascript but not the HTML. The HTML errors may get corrected in the Inspect Elements tool. As an example:
With in View Source you may observe:
<h1>The title</h2>
Whereas through Inspect Element that would have corrected as:
<h1>The title</h1>
getPageSource() always returns the markup obtained through View Source.
