I am having the following issue in my Capybara environment:
I need to search for an element. This element contains an attribute, which is unique. The attribute is changed asynchronously.
I need the content of this attribute, but when I just search for the attribute I am getting a nil.
I could wait until the attribute has the property, but since this is Capybaras job, I thought there might be a possible selector, which can search for something like:
find('button[uniqueattribute] != nil')
Any ideas how to do this?
Thanks already!
If the attribute is being added to the button element (didn't have the attribute originally) then you can just do
find('button[attribute_name]')
which will wait (up to Capybara.max_default_wait_time seconds for a button element with that attribute to be on the page - https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors. To wait and then get the contents/value of that attribute you could do
find('button[attribute_name]')['attribute_name']
If you just want to wait until the attribute is either not there or not blank then you can do
find('button:not([attribute_name=""])')
If you need to ensure the attribute is there, but isn't blank it would be
find('button[attribute_name]:not([attribute_name=""])')
I found a possible solution:
You can check the length of an element by Xpath (which is awesome) with string-length.
So in my case the solution was:
find(:xpath, ".//button[#unique_attribute_name[string-length() != 0]]")
Now Capybara waits until the attribute has a value. If there are more pretty solutions, just tell me.

I am using Selenium WebDriver and I have number of items on a page and each item on page is a separate form type.
I have saved all of these form elements in a list and I am iterating over every item in an attempt to get the name of the element by using the "alt" attribute.
However when I try to get the "name" attribute from the input element it is always returning the first input tag found on that page, not the name attribute of the element I have currently selected.
The syntax I am using is:
((Webdriver imgtags.get(i)).findelement(By.xpath("//input[#name='qty']")).sendKeys ("100");
I have also tried to get the id from the tag by using:
((Webdriver imgtags.get(i)).getAttribute("id");
It's returning a blank value, but it should return the value of the id attribute in that input tag.
I also tried to get the id by using .bytagname but as id is an attribute it is not accessible
Try:
(driver) findElement(By.xpath("//*[contains(local-name(), 'input') and contains(#name, 'qty')]")).sendKeys("100");
To answer the comment by #rrd: to be honest, I have no idea why OP uses ((Webdriver imgtags.get(i)). I don't know what that is. Normally, I just use driver.findElement[...]
Hoping that he knows what works in his framework :D
Selenium Xpath handling is not fully compliant and it does not always treat // as a synonym of descendant-or-self.
Instead try tweaking your code to use the following Xpath:
((Webdriver imgtags.get(i)).findElement(By.xpath("./descendant-or-self::input[#name='qty']")).sendKeys("100");
This will base your search off the currently selected WebElement and then look for any descendants that have a name attribute with a value of "qty".
I would also suggest storing your imgtags array as an array of WebElement e.g.
List<WebElement> imgtags = new ArrayList<>();
This is a much better idea than casting to WebDriver to be able to use .findElement(). This will cause you problems at some point in the future.
in my page object I have simple method
def clickSomething(byName) {
$("a.name", text: contains(byName)).click()
}
and during execution it does not find required element and goes further.
it happens because, according to documentation, $() returns EmptyNavigator if element not found.
I want for test to fail with some kind of "ElementNotFoundException" or "NullPointerException" on trying to make click on null element.
I also do not want to add additional checks for returned element (because I would need to add that for every element identification).
Is there an elegant workaround for that ?
e.g. for elements declared within "content" there is performed such a check. But what is the best practice for elements found outside content block ?
The issue that you've encountered which is click() not throwing an error when called on en empty navigator has been fixed recently and will be released in the next version of Geb.
If you need to get an error when a selector results in an empty navigator then you can either:
wrap your selector in a content definition with the required template option set to true which is the default
call verifyNotEmpty() on your navigator
I am not able to find the element using "id" in selenium as the id is randomly changing in every session of execution so the same id i am not getting in next execution.
As there is no other unique property is there to identify the element.
code sample
You didn't specify a language so I'm going to give you Java. You can do this by using the CSS class or probably a better choice (because of likely uniqueness) is data-lynx-name.
By CSS class
driver.findElement(By.cssSelector("div.http-lynx-json-org-text-input"));
By attribute
driver.findElement(By.cssSelector("div[data-lynx-name='username']"));
You really should read the question that I duped this one to:
Find element by attribute
Also read more about CSS selectors,
http://www.w3.org/TR/selectors/#selectors
You can use XPath.
String xpath = //div[#data-lynx-name='usernameLabel'][text='User ID']/following-sibling::div[1]
The above XPath will will find the div tag containing text 'User ID' and finds the next div which is is the required textbox.
It seems that you can even use the attribute 'data-lynx-name' attribute of the textbox div tag directly.
String xpath = //div[#data-lynx-name='username']
Selenium
driver.findElement(By.xpath(xpath));
I am using selenium for automating test cases for web application in that I have to get tool tip text
I tried
String result =element.getAttribute("span");
but this is retuning null. how can I get the text ?
element.getAttribute("span");
span must not be an attribute of the given element. I guess you've misunderstood, the getAttribute() method.
For e.g.
Example
For the above anchor tag, in order to get the title attributes' value, you can use :
element.getAttribute("title");
where element refers to the above anchor element.
I know I can find element by id:
driver.findElement(By.xpath("//*[#id='some_id']"));
And I can find all elements with this id, but I want to find all elements with an id attribute. I'm looking for something like:
driver.findElements(By.xpath("//*[#id]"));
// or
driver.findElements(By.xpath("//*[#id='*']"));
// or
driver.findElements(By.xpath("//*[contains(#id)]"));
I'm using Java. Thanks!
UPD: The only solution for me is to get all elements by "//*", go through them and get their id attributes. Is there a way to get all attributes at once, something like "//*#A" from Java?
Attribute A of element where A contains 't'
//E[contains(#A,'t')]/#A
or
//E[contains(#A,'t')]#A
Attribute A of any element
//*/#A
or //*#A
so I use java too. So if you need to find all elements with id attribute you can simply use
driver.findElements(By.xpath(//*#id))
Hope this helps you.
ALso look here. Nice manual for xpath and css selectors
have you tried "//*[contains(#id, '')]"
