[Drupal] How to clear the Drupal cache?

When a user frequently visits a webpage, the browser automatically saves or in other words caches that particular page. This helps the user to access those pages in future which saves time.

Therefore it is important that testers clear the cache before they start testing. Caching can be performed by both the site and the browser. Read on to know how to clear the Drupal cache.
