How would a tester use Google Chrome Dev Tools

Open any website (preferably techerds.com) in Google Chrome. Right-click and select “inspect element”. A tab similar to below should appear.

  • Elements - HTML that the page consists of.

  • Console - JavaScript interface allowing users to enter additional JavaScript as well as displaying any JavaScript errors that exist on a given page.

  • Sources - files and assets being called by the page.

  • Network - stats and details referring to the delivery of each network request the page requires.

  • Performance - similar to network with more in-depth controls (not something you need to worry about).

  • Memory - more useful for developers than testers but gives further insights into the performance of the page in the context of the application code associated with the page.

  • Application - provides insights into data being generated and used by the page

  • Security - illustrates what measures are being taken by the page to protect user data and activity on the page

  • Lighthouse - details relating to Google’s own page speed metrics.

See if you can find the below values for Techerds homepage.

  • Page load

  • Page size

  • Contents of the meta description.
