I try to find text on the page driver.findElement(By.xpath("//label[contains(text(),'Some text')]"));
I know that text not displayed in the page. But system accepts test as Successed.
Why System doesn't show Error about NoSuchElementException
You do not use the result of driver.findElement(By.xpath("//label[contains(text(),'Some text')]")); like not clicking it driver.findElement(By.xpath("//label[contains(text(),'Some text')]")).click(); or something else.
Calling the driver.findElement(By.xpath("//label[contains(text(),'Some text')]")); returns null but you do not assert or verify the result in any way.

So very new here to Selenium but I'm having trouble selecting the element I want from this website. In this case, I got the x_path using Chrome's 'copy XPath tool.' Basically, I'm looking to extract the CID text (in this case 4004) from the website, but my code seems to be unable to do this. Any help would be appreciated!
I have also tried using the CSS selector method as well but it returns the same error.
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.binary_location = '/Applications/Google Chrome Canary.app/Contents/MacOS/Google Chrome Canary'
driver= webdriver.Chrome()
chem_name = "D008294"
url = "https://pubchem.ncbi.nlm.nih.gov/#query=" + chem_name
driver.get(url)
elements = driver.find_elements_by_xpath('//*[#id="collection-results-container"]/div/div/div[2]/ul/li/div/div/div/div[2]/div[2]/div[2]/span/a/span/span')
driver.close()
print(elements.text)
As of now, this is the error I receive: 'list' object has no attribute 'text'
Here is the xpath that you can use.
//span[.='Compound CID']//following-sibling::a/descendant::span[2]
Why your script did not worked: I 2 issues in your code.
elements = driver.find_elements_by_xpath('//*[#id="collection-results-container"]/div/div/div[2]/ul/li/div/div/div/div[2]/div[2]/div[2]/span/a/span/span')
driver.close() # <== don't close the browser until you are done with all your steps on the browser or elements
print(elements.text) # <== you can not get text from list (python will through error here
How to fix it:
CID = driver.find_element_by_xpath("//span[.='Compound CID']//following-sibling::a/descendant::span[2]").text # <== returning the text using find_element (not find_elements)
driver.close()
print(CID) # <== now you can print `CID` though browser closed as the value already stored in variable.
Function driver.find_elements_by_xpath return list of Element. You should loop to get text of each element,
Like this:
for ele in print(elements.text):
print(ele.text)
Or if you want to match first Element, use driver.find_element_by_xpath function instead.
Using xpath provided chrome is always does not work as expected. First you have to know how to write xpath and verify it chrome console.
see these links, which helps you to know about xpaths
https://www.guru99.com/xpath-selenium.html
https://www.w3schools.com/xml/xpath_syntax.asp
In this case, first find the span contains text Compound CID and move to parent span the down to child a/span/span. something like //span[contains(text(),'Compound CID']/parent::span/a/span/span.
And also you need to findelement which return single element and get text from it. If you use findelements then it will return list of elements, so you need to loop and get text from those elements.
xpath: //a[contains(#href, 'compound')]/span[#class='breakword']/span
you can use the "href" as your attribute reference since I noticed that it has unique value for each component.
Example:
href="https://pubchem.ncbi.nlm.nih.gov/substance/53790330"
href="https://pubchem.ncbi.nlm.nih.gov/compound/4004"
I am using nightwatch with chrome driver for UI-Testing. I have come across an issue when trying to click on 'primary-btn' in the web-page. First the waitForElement returns a warning "Warn: WaitForElement found 2 elements for selector "#primary-btn". Only the first one will be checked" and the subsequent .click('#primary-btn') does not yield the desired result.
I checked the web-page to see if actually there are 2 elements with the name "#primary-btn" using document.getElementById('primary-btn'). However the function listed only 1 element with id 'primary-btn'
I am not sure why this happens. Does nightwatch support wait for animation to finish.
You should try this
document.querySelectorAll("div[id='primary-btn']:nth-child(1)")
In nightwatch :
browser.waitForElementPresent("div[id='primary-btn']:nth-child(1)")
It means that you have 2 elements in you page with an identical id. While the standard impose a unique name, it is not enforced in the browser. You can verify it by executing this command in your browser:
document.querySelectorAll("[id='primary-btn']")
Or:
$x("//*[#id='primary-btn']")
So to get the expected element, you need to extend your selector with another condition. It could be for example:
'#container-id #primary-btn'
I am having issues with selenium using the next xpath "./preceding-sibling::text()"
I don't understand why, my first thought was that IE wasn't supporting that xpath statement but it didnt work on chrome neither.
What I am trying to do is to verify if a radio button have a certain text "near" it. For example if a radio button is like this
<div>
<label> Yes <input name='radioBtn'></input></label>
<label> No <input name='radioBtn'></input></label>
</div>
This is a simplified scenario where I need to check the "yes" radio button, so what I am doing is to search for the radiobutton and check if it preceding-sibling::text(), but selenium is cant find any element. I know the Xpath works because I test it on chrome developer tools and it returns the text "Yes".
I can't do something like 'input[1]' because I can't be sure that the first one will be always that have the Yes text.
Any idea why isn't this working on selenium? and if there is any work around?
I got to a work around but is kind of specific to the problem. But let's answer the questions 1 at the time.
Any idea why isn't this working on selenium?
It's not working because selenium don't support text elements, so even when selenium find the element it cant map it to a selenium object, i didn't see it because my code hided the selenium exception. The Exception throw is the next one:
An unhandled exception of type
'OpenQA.Selenium.InvalidSelectorException' occurred in WebDriver.dll
Additional information: invalid selector: The result of the xpath
expression "./preceding-sibling::text()" is: [object Text]. It should
be an element
Is there any work around?
Yes it is. What I did was to run a java script using the selenium IJavaScriptExecutor. With the script I revised the preceding sibling text and return it as a string so if the text was equal to the thing I was looking for (i.e Yes) trhat means that is the radio button I was looking for.
The code looks is similar to this (it can have some sintax errors since I didn't copied from the source):
string script = "function GetPrecedingText(node){"+
"var result = document.evaluate('./preceding-sibling::text()[1]', node, null, XPathResult.STRING_TYPE, null);"+
"return (result==null) ? '' : result.stringValue.trim();}"+
"return GetPrecedingText(arguments[0])";
string result = ((driver as IJavaScriptExecutor).ExecuteScript(script, SeleniumElement)).toString();
Hope someone can find this useful :) and thanks for all that tried to help me :)
I am trying to run test cases to perform reset password and I am facing this issue.
WebDriverException Element must be user-editable in order to clear it.
Basically i am accessing the page for entering the new password and doing this:
browser.$("#newPassword").text("password");
where execution of the above line throws the error.
I had the same problem and it was because there was another element with the same id which was not an input field so it could not be cleared.
We can try the following:
WebElement.sendKeys(Keys.DELETE);
WebElement.sendKeys("Test");
It might be a case of using the wrong method for the input type.
In CodeCeption at least, fillField should be used on input elements and selectOption should be used on select elements and mixing them up will give invalid element state: Element must be user-editable in order to clear it.
I had this problem with a Primefaces autoComplete element. Primefaces 6.0 renders a span with the ID you pass, and within that an input with a "_input" appended to the ID. If you just use the ID you added in your source code, you tell Selenium to enter into the span (which fails with the "element must be user-editable" error). Add the "_input" to the ID if you select by ID in selenium.
I am trying to test a webpage using Selenium and NUnit. One of my test cases entails the validation of text boxes. Using Selenium and C#, I am able to retrieve the value entered in the text box. But when the validation of the text box fails, an error message is displayed next to the text box.
So, here are my questions:
1. How can I test if an error was raised due to validation failure.
2. Can I get the text of that error.
3. Or, am I way off the mark and what I am trying to do is not at all possible.
I have tried reading the value of the element, but it always seems to be an empty string.
Say, for example, I am trying to test the webpage https://edit.yahoo.com/registration . When I enter "**myname&&" in the First Name field, an error appears stating "Only letters, spaces, hyphens, and apostrophes are allowed". I want to be able to test that this error was raised.
Also, I noticed that when Selenium opens the webpage and enters an incorrect value in the text box, the error message does not get displayed next to this text box. Whereas, when I open the webpage myself and enter an incorrect text, the error message is displayed
Thanks!!
You will have to use thread.sleep, but in a better way. It's better to write a function like this (I am writing this in JAVA, you should be able to write it for C#). This method will wait for the specified number of seconds for the element to be visible. If the element is not visible even after the specified number of seconds, then the method will return false. If it becomes visible then the method will return true.
Alternatively, you can use an assertion instead of returning a false condition so that your test fails.
public boolean waitForErrorMessage(String elementToWaitFor, int waitTimeInSeconds)
{
int timeOut=0;
while(!selenium.isVisible(elementToWaitFor))
{
if(timeOut<waitTimeInSeconds){
#sleep for one second
Thread.Sleep(1000);
}
else {
return false;
}
timeOut=timeOut+1;
}
return true;
}
