I've looked at RESTinstance and RequestsLibrary, but can't find a way to send a GET to the server with JSON as part of my request. I am grateful for any advice.
Using the Get Request keyword from the RequestLibrary it could be done like below.
A JSON in general is a dictionary in Robot Framework. In the example below the &{JSON}
variable is equivalent with the following JSON:
{
"name": "peter",
"other_attribute": "value"
}
With additional keywords you could create nested structures as well.
Example:
*** Settings ***
Library RequestsLibrary
*** Variables ***
&{JSON} name=peter other_attribute=value
*** Test Cases ***
Test
Create session alias=my_session url=http://127.0.0.1:5000
${response}= Get Request alias=my_session uri=api/your_api_endpoint json=${JSON}
Log ${response}
