Error Message:
“OpenQA.Selenium.NoSuchElementException : no such element: Unable to locate element: {"method":"css selector","selector":"#LastName"}”
I get this error message on running the test scenario in test explorer.
SCREEN SHOTS:
ACTION ALREADY TAKEN TO FIX THE ISSUE:
1). I have carefully checked the line of code that appears to contain the error message.
Line 116 Of “StudentStepDefinitions” Seems To Contain The Definition For The “FamilyName”
public void FamilyNameField(string familyName)
That code seems to be ok. No errors are generated on that piece of code.
2). I have checked Google for more information about the error.
Information I have found so far:
- 1 Coder suggests applying a wait of 5000ms.
(Link: https://stackoverflow.com/questions/44572164/openqa-selenium-nosuchelementexception)
3). There is a suggestion to use the “expected conditions class” (Link: https://stackoverflow.com/questions/44179554/openqa-selenium-nosuchelementexception-c-sharp-selenium)
4). There is another suggestion to use “Driver.FindElement(By.LinkText(“…..”))
I am not sure how best to proceed, please. That is where I require assistance after doing this bit of research, please.
Any suggestions to fix the issue will be highly apprciated, please.
Many Thanks.
