As a developer you got a Magento 2 project, integrate theme, complete all customization, tested all sales functionality. Your project is now ready for production.
When you enter into backend catalog product grid, you will see all your test products. You can delete one-by-one or multiple at a time, right?
When you enter into backend sales order grid, unfortunately you won’t find any option to delete order! You know those should be deleted. But how?
You can either set their status as “Cancelled” or “Hold” but you can’t delete those test orders from your store.
Here is the post that help you to clear Magento 2 test data such as:

  • Clearing all products
  • Clearing all categories
  • Clearing all customers
  • Clearing all wishlists
  • Clearing all reviews
  • Clearing all search results
