How to Modify a Response and Send it back as Request in the Next Step

I need to store a JSON response in a property and change a certain value in the response property and pass it as a request to the next REST step.

How can I automate this process with DevTest?



All supported releases and platforms of DevTest.






Here is an example if the response has always the same structure, and we want to modify one specific field of this response.

1. Have the value you want to update in the response saved in a property or get the value from a data set.

In the example below, I am using the data set, "Random Code Generator", to generate a random value, and I am saving this value to the property "newPrprty".


2. Add an "Output Log Message" step after the REST step that receives the response you want to modify.


3. Copy the response from the REST step to the new "Output Log Message" step and modify the field you want to update with the property saved in the step #1 – {{newPrprty}}.


4. In the REST step, that will send the updated response as the request, place the "Output Log Message" step response as the request body – {{lisa.Output Log Message.rsp}}.


5. Save the modified Test Case.

When you run the test in the ITR you can see the new property being set in the first step:

The static response being updated in the "Output Log Message" step:


The response of the "Output Log Message" step being sent as the request body in the REST step:
