Azure Devops Failing on npm install (Cannot find module 'Selenium-Webdriver'

According to the error message:

Error: Cannot find module 'selenium-webdriver'

And the configuration screenshot of the build definition, we could to know that you execute the npm test directly without the packages. we need to use npm install command line to ensure that all the packages are installed:

npm install selenium-webdriver --save or npm install

You could check this thread for some more details.
