Lack of effective testing tools for asyncio applications
The Problem
Developers working with asyncio in Python face significant challenges when trying to test time-dependent functionality. Current mocking libraries like freezegun and time-machine do not integrate well with asyncio, leading to real delays during tests, which complicates scheduling tests over extended periods. This gap in testing tools creates frustration and inefficiencies for developers who need reliable and fast testing solutions for their asynchronous applications.
Market Context
This pain point aligns with the growing trend of asynchronous programming in Python, especially with the rise of frameworks like FastAPI and asyncio itself. As more developers adopt these technologies, the demand for robust testing tools that cater specifically to asynchronous workflows is increasing, making this an opportune moment for new solutions.

“If it weren't for asyncio, this would be easy - just use freezegun or time-machine - but neither library plays particularly nice with `asyncio.sleep`.”

“These tools weren't really built with Protobuf as the primary use case, and that's completely fair. Most APIs are REST.”

What You Could Build
AsyncMocker
Full-Time BuildA mocking library designed specifically for asyncio testing.
With the rise of asyncio usage in Python, developers need tailored tools for efficient testing.
Unlike existing libraries, AsyncMocker would be built from the ground up to handle asyncio's event loop and scheduling without real delays.
TimeWarp
Side ProjectA time manipulation library for asyncio applications.
As more applications leverage asyncio, the need for effective time control in tests is critical.
TimeWarp would offer seamless integration with asyncio, allowing developers to simulate time without actual delays, unlike freezegun.
AsyncTest Suite
Full-Time BuildA comprehensive testing suite for asyncio applications.
The increasing adoption of asyncio necessitates specialized testing solutions to ensure code quality.
This suite would provide built-in support for common asyncio patterns and testing scenarios, unlike general-purpose testing tools.
