⛏️ Write test for parameter pollution

[ankush-jain-akto]

💭 Introduction
Create a YAML test to check for parameter pollution in a POST request.

📚 Reading

You can find a detailed documentation of test editor rules here

Find 100+ examples of YAML tests here

🎯 Requirements

1. Filters - The test should run only on POST APIs that have at least 2 input arguments in the JSON

2. Execute - It should remove 1 entry and add the removed key-value pair at the end of a different value.
   For example, eg, if original payload looks like

{
    "name": "John",
    "age" : "36"
}

the attempt should look like

{
    "name": "John&age=36"
}

3. Validation - If the application responds with a positive response code and response body is 80% similar to the original mirrored Response body, the API endpoint is vulnerable to this kind of input validation flaw.

Hi @nandini584 . Your yaml is invalid. Also you have missed some fields in the test template. Please run the templates and only on successful run submit a PR.

[nandini584]

Yeah, sure I will redo it.
