The syntax of Rest Assured.io is the most beautiful part, as it is very
BDD like and understandable.

Given(). (lets you set a background)
        param("customer_id", "102").
        header("z", "w").
when(). (marks the premise of your scenario. For ex: get url)
Method(). (replace it with any of CRUD operations like get post put delete)
Then(). (your assert and matcher conditions goes here)
        statusCode(xxx).
        Body("x, "y", equalTo("z"));
