Chaining

This is the mechanism on how to chain scenarios for Autokin. Let us say that you want to Login the user then use the session token to retrieve user information.
1
    POST https://www.autokinjs.com/login

        "username": "juan",
6
        "password": "p3dr0"
7
    }

    Scenario: Login to the system
7
        Given that a secure endpoint is up at www.autokinjs.com
8
        Given I set Content-Type header to application/json
9
        Given I set the JSON body to 
10
        """
11
        {
12
            "username": "juan",
13
            "password": "p3dr0"
14
        }
15
        """
16
        When I POST /login
17
        Then response status code should be 200
18
        Then I keep the value of body path "$.sessionId" as "userSessionToken"

    Scenario: Get user information
21
        Given that a secure endpoint is up at www.autokinjs.com
22
        Given I set Content-Type header to application/json
23
        Given I set SessionId header from "userSessionToken"
24
        When I GET /user/1001
25
        Then response status code should be 200

As you see in the above example, we login then we store the session token to a variable userSessionToken, the variable name can be anything as long as a one word. Following to our next scenario, as needed by our API, we set the header SessionId to the value of the previously stored data by specifying that we are getting the stored value from the variable userSessionToken.
