Pytest Vim Syntastic-避免重新定义警告

Question

I've set up Syntastic in Vim for Python development. Its been fantastic so far, but when writing tests with imported pytest.fixture methods, I get a few bogus errors. For context, I'm using Flask in Python. But, consider the following test.py example:

from common_stuff import app, client

def test_some_flask_think(client):
    # some test stuff

And in common_stuff.py :

@pytest.fixture
def client(app)
    return app.test_client()

If they're in the same file - no complains from Syntastic. However, in a separate file - no luck. An F811 error is listed in each instance.

Someone well likely has encountered the same thing before. Would greatly appreciate advice / pointers here.

Thanks!

Answer 1

To answer my own question, and in hopes of kindly educating others who may run into the same issue...

Syntastic can use a variety of linters for Python. The default which was configured on my system happened to be flake8 . I was able to determine this by running :SyntasticInfo while a Python buffer was active in Vim.

The error noted above, has a code of F811 which is also documented in the Flake 8 error code docs . After additional research, this may well be a bug in Flake8 . However, there is a more idiomatic solution with pytest, noted in the following SO post . A concrete example of conftest.py can be found in this post . In a nutshell, common_stuff.py can be renamed to conftest.py , the import removed, and pytest will bootstrap the necessary test fixtures accordingly.
