Dryrun-Python

Dryrun-Python makes it very easy to run a python program without actual i/o operations. It can help you to fully focus on your business-logic without worrying about the i/o operation.

Key features

• It supports async functions.
• You can specify a return value.
• Or, you can use mock function which is called instead of original function.

How to install

pip install dryrun

from dryrun import dryrun

How to use

Just import dryrun and use it as a decorator.

@dryrun()
async def delete_comment(comment_id: str) -> bool:
    response = await api_client.delete_comment(comment_id)
    return response.success

If dryrun is enabled, the real function won't be called.

And If you want to specify a return value, you can use return_value argument.

@dryrun(return_value=True)
async def delete_comment(comment_id: str) -> bool:
    response = await api_client.delete_comment(comment_id)
    return response.success

But it's not enough for some cases. Then, you can use mock function which is called instead of the real function.
Just like it!

@dryrun()
async def create_comment(payload: dict) -> dict:
    response = await api_client.create_comment(payload)
    return response.paylaod

@create_comment.mock
def create_comment_mock(payload: dict) -> dict:
    return {
        "id": uuid.uuid4(),
        "content": payload["content"],
    }
