asyncmock
Extension to the standard mock framework to support support async
Decision gist · record as of 2026-08-14
No, not for new projects. The description explicitly notes that Mock 4.0+ (included within Python 3.8+) now includes mock.AsyncMock and recommends it for new projects. For legacy Python 3.6–3.7 codebases, this package is an option, but its abandonment means no maintenance or compatibility updates.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.6 or later; requires an async runtime context to execute the await statement.
- Low friction installation with a single runtime dependency (mock).
- However, the package is archived and abandoned since 2022-08-22, with no releases after 2020-03-15.

What it is and what it does
Asyncmock extends the standard mock library to support testing async code by providing an AsyncMock class that behaves like a regular Mock but can be awaited. It handles async method calls, side effects, and return values, allowing developers to mock coroutines and async functions in unit tests.
The package was designed as a backport for Python versions before 3.8, when awaitable mocks were not yet part of the standard library. It is now superseded by built-in functionality—the description notes that Mock 4.0+ (included within Python 3.8+) now includes an awaitable mock mock.AsyncMock, which is recommended for new projects. The package is no longer maintained—its repository is archived and the last release was in 2020-03-15.
Use it for
- Mock async functions in unit tests for Python 3.6–3.7 projects that predate built-in AsyncMock
- Test async methods with call assertions and side effects in older codebases
- Verify that async code correctly awaits mocked coroutines during development
