WebDriver HtmlUnitDriver NoSuchElementException - webdriver

I'm using Webdriver to test my web application. When I work with FireFoxDriver or ChromeDriver everything seems to be ok. When I work with HtmlUnitDriver though things start to go wrong.
Here is a sample code:
WebDriver driver = new HtmlUnitDriver();
driver.get("http://localhost:8099/");
WebElement loginButton = driver.findElement(By.xpath("//button[#type='button']"));
loginButton.click();
i'v looked at the driver.getPageSource result, and the source code presented there is very partial.
it doesnt show me all the elements. it is the same a clicking view source on the page.
what i need from the driver is the entire source, like firebug or chrome inspector give me.
any ideas on how i can retrieve it?
my app was written with the GWT.
thanks a million

Have you tried to enable JavaScript for HtmlUnitDriver?

I believe that the HTMLUnitDriver emulates IE by default (link) and there are other questions related to clicking buttons with IE. Have you tried this?
// Press enter on the button
loginButton.sendKeys("\n");
Also, have you tried adding an ID to the element and using that to find the button?

Nightwatch Cannot Find/Click on Dropdown Option

I'm a backpacker and a programmer, trying to use the second skill to find openings in a full campsite. Rather than crawling fro scratch, I'm using the end-to-end testing framework nightwatch.js to navigate for me.
I've hit a roadblock, because nightwatch is having difficulty finding a specific element using css selectors.
Here are the elements and page:
Here is my test code:
Previous Attempts
My test code will click on the selection box with #permitTypeId. It will see that #permitTypeId option is visible. It will not see or click on any of the options when more specific values are specified. The five .click()'s are all css selectors I've already tried. None of the options are set to display:hidden or display:none. I have also tried all of the above without the .waitForElementToBeVisible() just in-case the waiting causes the dropdown to hide.
I've successfully clicked options from different dropdown menus on this website without any problem. Just this one is causing a headache.
The tests are running with the most current Selenium server and Firefox on Mac Yosemite.
tl;dr
Nightwatch.js/Selenium won't click on something from a dropdown menu.
The Path...
Cory got me thinking about jQuery and native DOM manipulation. Tried going that route and was successful selecting the correct option using Selenium's .execute() function:
.execute('document.getElementById("permitTypeId").options[1].selected=true')
However, it was not triggering the onchange event.
Saw this post which made me start thinking about using key-strokes and this one which suggested using arrow-keys to navigate down a <select> element to the option, then hitting enter.
...to the Solution
.click('select[id=permitTypeId]')
.keys(['\uE015', '\uE006'])
I've found that this is an issue with Firefox. Chrome and PhantomJS operate well clicking <option> tags.
you should be able to click like this way
browser.click('select[id="permitTypeId"] option[value="1451140610"]')
Additionally I was able to add a .click event for the specific option once I did a .click for the select. see my example below:
.click('select[name="timezone"]')
.pause(1000)
.click('option[value="America/Chicago"]') //selects the option but doesn't click
.pause(5000)
.keys(['\uE006']) //hits the enter key.
another solution:
.click('select[id="permitTypeId"]')
.waitForElementVisible("option[value='1451140610']")
.click("option[value='1451140610']")
Very simple way is to use .setValue('#element', 'value of option')

Radeditor on google chrome not working

I have a telerik rad editor. My application runs in .net 2.0 environment. The telerik version is : 2012.3.1016.35. The rad editor is not enabled on chrome only. I cannot type into it.Works fine in all other browsers. Upgrading to new telerik is not an option. Because this is an old client and changing will/may affect other styling things.
So what are my options. I posted this on telerik, but no response. If you need more information, please let me know. Thanks.
EDIT:
ON checking the console I got an error. Please find the image attached to see the error.
SOLUTION:
I got it. I had a line like below to open a rad window:
rwSC.VisibleOnPageLoad = True
This was causing the problem. Sometimes it would open fast and the control would load and I can place my cursor within the rad editor within the rad window and sometimes cannot. So I replaced that with this
Javascript.RegisterStartupScript(Me, "NewSC", "setTimeout(""$find('" & rwSC.ClientID & "').show();"", 500);", True)
And now it works. The rad editor within the radwindow is enabled and I can edit it.
Is this what you have: http://feedback.telerik.com/Project/108/Feedback/Details/125713?
If so, try the JS workaround there

WebDriver open rich:popupPanel

We are testing an application with Selenium WebDriver. HTMLUnitDriver is our choice (because of non-gui-testing) and sometimes IEDriver for Presentationpurposes. Anyway, i try to perform a click on a button, this one has to open an rich:popuPanel(modal=true) and click a Link on that Panel. With IEDriver that's no problem, but with HTMLUnitDriver the popupPanel doesn't open. I tried to perform these clicks in several ways:
JavascriptExecutor jsdriver = (JavascriptExecutor) driver;
jsdriver.executeScript("$('input[id$=freigabeCmd_id]').focus();");
//below are the other tries
// jsdriver.executeScript("$('input[id$=freigabeCmd_id]').click();");
// jsdriver.executeScript("window.document.getElementById('editorViewForm_id:freigabeCmd_id').click()");
// jsdriver.executeScript("arguments[0].click()", freigabeButton);
// jsdriver.executeScript("arguments[0].fireEvent('onclick');", freigabeButton);
further i tried it the "normal way":
freigabeButton.click();
//below are other ways i found here on stackoverflow
// freigabeButton.sendKeys(Keys.ENTER);
// new Actions(driver).moveToElement(freigabeButton).clickAndHold().release().build().perform();
but nothing brought me to get the popupPanel "visible". Anyone got an idea why?! i'm really stuck right now. If you need more Informations pls let me know.
using: HTMLUnit Version 2.12 and latest SeleniumVersion
It might be that your webapp uses javascript to launch the rich pop-up panel, and you are running HtmlUnitDriver with javascript disabled? It is disabled by default, so you need to explicitly enable it.

Selenium and iframe

I have an iframe that gets loaded when i click on a tab on a page. When i use Firebug to look at the iframe on IE8, all i see is:
iframe id=tabContextFrame class=contextFrame contentEditable=inherit src=/xyz.dt?forward=show&layouttype=NoHeader&runid=1234 name=tabContextFrame url=/xyz.dt?forward=show&layouttype=NoHeader&runid=1234 scrolling=auto
and that's it.The hierarchy below the iframe can't be seen. I want to click on a link within the iframe. To find the elements within the iframe, I did a selenium.click("on the tab that loads the iframe") and then selenium.getHtmlSource(). From this source, I can at least locate my link of interest. I did a selenium.click("//span[text()='Link']") but it doesn't seem to do anything. Any ideas please?
Here is the code:
selenium.click("//span[text()='tab that loads iframe']");
Thread.sleep(5000);
selenium.selectFrame("tabContextFrame");
selenium.mouseOver("//span[text()='Link']");
selenium.mouseDown("//span[text()='Link']");
selenium.mouseUp("//span[text()='Link']");
Thread.sleep(5000);
selenium.selectFrame("null");
I'm guessing you are using Selenium 1.0. Have you looked at Selenium 2.0 and WebDriver. I found the following and it worked for me:
Q: How do I type into a contentEditable iframe? A: Assuming that the
iframe is named "foo":
driver.switchTo().frame("foo");
WebElement editable = driver.switchTo().activeElement();
editable.sendKeys("Your text here");
Sometimes this doesn't work, and this is because the iframe
doesn't have any content. On Firefox you can execute the following
before "sendKeys":
((JavascriptExecutor) driver).executeScript("document.body.innerHTML = '<br>'");
This is needed because the iframe has no content by default:
there's nothing to send keyboard input to. This method call inserts an
empty tag, which sets everything up nicely.
Remember to switch out of the frame once you're done (as all further
interactions will be with this specific frame):
driver.switchTo().defaultContent();
I found this on http://code.google.com/p/selenium/wiki/FrequentlyAskedQuestions
Use driver.switchTo().defaultContent(); first then do your operation

JS window.close() let IE hang

for reason I won't bore you with, I'm writing an asp.net application that must open some pages in new browser windows.
I managed to open them within a postback (don't ask why, I just needed to) with this code:
script = String.Format(#"window.open(""{0}"", ""{1}"");", url, target);
ScriptManager.RegisterStartupScript(page, typeof(Page), "Redirect", script, true);
Now I have new windows each one with a button that should close it. I have simply an onclick="window.close()" (but that prompts me when I'm closing the browser) or window.open('','_self','');window.close() (horrible, I agree but it's the only way I found to avoid the JS prompt)
On firefox it works perfectly but on IE7 (the browser our customers have) after 2-3 times I use that button to close the window I can't open other windows (in both cases, with or without the JS prompt). With the method above it does nothing, and with a click me a new window is opened but hangs on loading (it doesn't even calls the Page_Load).
What could be the cause? How can I solve this?
Thank you.
EDIT:
I forgot to mention that I'm using MS Ajax in most of the pages, and that may be the reason that forces me to use window.open('','_self',''); before window.close()
I don't know if this could cause also the hanging of IE
EDIT: Ignore that, it does still prompt the user - sorry!
For your first issue about closing the window, have you tried:
self.close();
Not too sure about the hanging issue though, I use window.open() and have never experienced issues in IE7.
I finally came to a solution:
on the attribute assignment there was a return false; missing.
Now it works perfectly with "window.open('','_self','');window.close();return false;".
