CRUD Operations in K6 | Tech

Reading Time: 2 minutes

Hi Readers, In this blog, I am going to explore, HTTP methods in K6.

Basically, HTTP methods are also called HTTP verbs and CRUD operations because it is a set of requests which perform the desired actions like get, put, post, delete and so on.

CRUD stands for Create, Read, Update and Delete. These are four primitive database operations that map well to the HTTP verbs most frequently used in Rest Services.
