PoC GSOC API Testing Suite - Abhinav Sharma

[abhinavs1920]

PR Description

This PR introduces the initial Proof of Concept implementation of the API Testing Suite, as outlined in my GSoC proposal. The suite extends APIDash’s testing capabilities with a drag-and-drop workflow builder, stress testing tools, and a fake data generation service.

Features Implemented

Workflow Builder

• Added a drag-and-drop canvas for building API workflow chains
• Node and connection layers implemented for visual flow representation
• Execution engine supports sequential API call execution
• Basic state management for execution (start/pause/stop)

Stress Testing

• Developed a stress testing service for parallel API execution
• Utilized isolate-based processing for better performance
• Tracks results with basic metrics (response time, status codes, etc.)
• UI elements included to display test results and summaries

Fake Data Provider

• Created a service for generating random test data (emails, usernames, etc.)
• Supported random data injection into request bodies
• Interface to configure generation parameters

Current Limitations

• Error handling in edge cases is limited
• UI requires further refinement for improved usability
• Workflow Builder lacks conditional node types
• Test result visualization is basic (to be enhanced in future iterations)
• Lot of checks are not added in it.

Next Steps

As per the GSoC roadmap:

• Enhance Collection Runner with advanced execution options
• Add conditional logic support to Workflow Builder
• Implement detailed monitoring and analytics

I have made limited use of AI tools such as ChatGPT and Claude, primarily for occasional code suggestions, template generation, and documentation assistance.

Hi @ashitaprasad @animator @DenserMeerkat I have added this PR to show my PoC for API Testing Suite, I mainly focused on setting up the project structure and ensuring proper separation of concerns. The code is loosely coupled so that api_testing_suite exists as a separate package and is not placed inside the main src, as per with APIDash’s existing architecture.

I plan to continue working on it, but I’ll have limited time over the next week due to upcoming examinations.

I would be really appreciate a review—good or bad. I just want honest feedback at this stage to know if I’m heading in the right direction.

Thanks a lot!

@ashitaprasad @ashitaprasad @DenserMeerkat Hi, Is there any feedback for approach I used, I would like to implement further things in this PoC. Let me know if the implementation is well suitable for the project?

Thanks!
