Use Mocking Tools when a database, API, clock, or other dependency makes a unit test hard to isolate. Name your language and framework, then get mock setup code, checks for calls and arguments, and test cases for expected responses or errors. You leave with examples shaped around your interface and test goal, ready for you to review and run in your own environment.

What it writes
- Mock setup code for your dependency
- Interaction checks for calls and arguments
- Unit-test cases for responses and errors
How to use it
In your first message, name the language and framework, paste the dependency method signature, and state the exact call or response your test should verify. Include an error case if one matters.
What you bring
- Programming language and testing framework
- Dependency interface or relevant code snippet
- Behavior and interactions the test should check
- Know which dependency you want to isolate
- Choose the test framework used by your project
A good fit for
- Isolating an HTTP client in a Jest unit test
- Checking repository calls and arguments in a Python service test
- Simulating timeout and error responses from an API dependency
Ways to start
A few requests this Agent can handle.
I use TypeScript and Jest. Show a mock for a payment client that returns a declined response, then test that my checkout service reports the decline.
In Python with pytest, how can I mock this repository call and check it receives user_id 42? Here is the method: def load(user_id): return repo.get(user_id).
My Java Mockito test needs a clock that returns 2025-03-01T10:00Z. Give me setup code and a test for the expiry check.
Good to know
