We are using https://demoshop.skyramp.dev/api/v1/products as a placeholder here for your <url-to-endpoint>.

skyramp generate fuzz rest https://demoshop.skyramp.dev/api/v1/products \
--language python \
--framework robot \
--response-status-code 20x \
--api-schema openapi.json

This command generates a fuzz test file: products_fuzz_test.py.
The content of the generated test is explained here.

3. Execute Fuzz Test

You can execute the generated tests without any additional adjustments to the code.

3.1 Set env variable for authentication (if needed)

Ensure proper authentication for test execution. By default, we expect a Bearer Token but support additional authentication methods. If your API does not require any authentication, you can skip this step and just run the test.

export SKYRAMP_TEST_TOKEN=$your_bearer_token

3.2 Run the test

We now run the test using the Robot Framework. You can call the generated Python file either in an existing robot file or leverage this example file skyramp_test.robot:

*** Settings ***
Documentation     Proof of Concept fuzz pytest under the hood of Robot Framework
Library  products_fuzz_test.py


*** Test Cases ***
Skyramp Test
    Test products post

You can now execute

# Prerequisites
pip install robotframework

# Execution of fuzz test for products/POST 
robot skyramp_test.robot

3.3 Results

As we use the Robot Framework to execute the test in this example, you can expect both the typical stdout from Robot and the generated files (output, log, report). You can find more information on the generated outputs in the Robot documentation.

3.3.1 Successful Test

Using the simple POST method example of the /api/v1/products endpoint, the test passes out of the box.

3.3.2 Test Failure

For this section, we intentionally changed the expected response body to create a failure. You can find more detailed information about the test failure in the report.html and log.html.
