Troubleshooting issues encountered while using mocha and selenium webdriver with npm

While trying to run Selenium webdriver with Node and Mocha on Ubuntu 18.04, I encountered the following errors:

  1) Google search automated testing
       find the input box and google search button:
     TimeoutError: Element not found
Wait timed out after 15002ms
      at /root/test/node_modules/selenium-webdriver/lib/webdriver.js:834:17
      at runMicrotasks (<anonymous>)
      at processTicksAndRejections (internal/process/task_queues.js:93:5)

  2) Google search automated testing
       put keyword in search box and click search button:
     TimeoutError: Element not found
Wait timed out after 15005ms
      at /root/test/node_modules/selenium-webdriver/lib/webdriver.js:834:17
      at runMicrotasks (<anonymous>)
      at processTicksAndRejections (internal/process/task_queues.js:93:5)



[mochawesome] {
  "killed": false,
  "code": 3,
  "signal": null,
  "cmd": "xdg-open /root/test/mochawesome-report/mochawesome.html"
}

What additional details do you require? Is there a way to debug this issue?

I am currently using this repository as my base for experimentation. (https://github.com/bmshamsnahid/Automation-With-Selenium-And-Node.js)

Answer №1

Greetings! It appears that there may be an error with certificate validation. One workaround for this issue in Chrome is to disable it using the following option: --ignore-certificate-error

Answer №2

Removing the headless option results in:

npm ERR! Test failed. See above for more details.

It seems the solution to this error was indeed to run it headless.
