API tester agent - Submission agent for #QodoAgentChallenge

[apis3445]

User description

API tester agent will create for all API or one API reading the open api documentation with option to include negative scenarios

• test plan
• test cases with C# and rest assured

The parameters are:

• swagger_url: URL to the openapi documentation
• output_dir: Directory where test files will be created
• test_framework: C# test framework to use NUnit, xUnit, TUnit or MSTest. By default NUnit
• namespace: C# namespace for the generated test classes
• include_negative_tests: true to generate negative scenarios,
• base_url: Override base URL for API testing (if different from Swagger spec)
• single_api: specific API endpoint to test (e.g., '/pet/{petId}' or 'GET /pet/{petId}'). If provided, only this endpoint will have tests generated

Example:

qodo api_test_plan
--set swagger_url="https://petstore.swagger.io/v2/swagger.json"
--set single_api="POST /pet"
--set include_negative_tests=true \

--set output_dir="Pet/Tests"

PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Auth config mismatch Description: Global security requires Bearer auth, but several endpoints like '/api/Users/Login' and '/health' appear to be public by nature; without explicit security overrides, generators/clients may incorrectly require tokens for login/health—verify spec correctness to avoid auth bypasses or accidental exposure. swagger.json [2246-2251] Referred Code "security": [ { "Bearer": [ ] } ] }
Ticket Compliance

PR Code Suggestions ✨

Category	Suggestion	Impact
Possible issue	Fix unusable authentication endpoints Make the /api/Users/Login, /api/Users/RequestPassword/{user}, and /api/Users/ResetPassword endpoints public by adding "security": [] to their definitions to override the global Bearer token requirement. swagger.json [1310-1336] "/api/Users/Login": { "post": { "tags": [ "Users" ], "summary": "Login", + "security": [], "requestBody": { "description": "Data for login", "content": { "application/json": { "schema": { "$ref": "#/components/schemas/LoginDTO" } }, "text/json": { "schema": { "$ref": "#/components/schemas/LoginDTO" } }, "application/*+json": { "schema": { "$ref": "#/components/schemas/LoginDTO" } } } }, "responses": { ...
