Unit Test Scheduled Async

What it does

This skill enables AI agents to write and execute unit tests for scheduled asynchronous functions. It supports testing time-based logic, such as cron jobs or delayed tasks, ensuring they run correctly under various conditions.

When to use it

• Testing background tasks that run at specific intervals in a web application
• Validating the behavior of async operations with timeouts or delays
• Ensuring scheduled functions handle errors and edge cases properly

Key capabilities

• Simulating time progression for testing scheduled logic
• Mocking async behaviors like timers or external API calls
• Running isolated unit tests without side effects

Example prompts

• "Write a unit test for a function that runs every 5 minutes using Jest."
• "Mock the setTimeout function and test an async scheduled task."
• "Verify that my cron job handles errors gracefully in a test environment."

Tips & gotchas

• Ensure your testing framework supports asynchronous operations, such as Jest or Mocha.
• Be mindful of global time mocks that might interfere with other tests if not reset properly.
