Why Can't Selenium Find My 'Next' Button: Troubleshooting NoSuchElementException?

Unable to Locate "Next" Button with Selenium: Troubleshooting 'NoSuchElementException'

When encountering the error message "selenium.common.exceptions.NoSuchElementException," it indicates that the Selenium ChromeDriver cannot find the specified element.

Locating the Desired "Next" Button

Based on the provided HTML code, the "Next" button can be located using the following Locator Strategies:

• CSS Selector:

  driver.find_element_by_css_selector("input[name='submitNext'][value='Next']").click()

• XPath:

  driver.find_element_by_xpath("//input[@name='submitNext' and @value='Next']").click()

Version Incompatibility Issues

However, the main cause of the error is likely the incompatibility between the versions of Selenium, ChromeDriver, and Chrome Browser.

• ChromeDriver: Version 2.36
• Chrome: Version 66.0

Compatibility issues can occur when using older versions of ChromeDriver with newer versions of Chrome. For the current version of Chrome (66.x), ChromeDriver v2.38 is required.

Solution

To resolve this issue, it is recommended to:

1. Upgrade Selenium to the latest version (3.11.0 at the time of writing).
2. Upgrade ChromeDriver to the latest version (2.38 at the time of writing).
3. Use a matching version of Chrome Browser (v66.x).
4. Clean the project workspace and rebuild with the updated dependencies.
5. Use a tool like CCleaner to remove any potential OS issues.
6. Consider upgrading the base Web Client version.
7. Reboot the system.
8. Re-run the test.
