vim module mock for easier testing of plugins for Vim

vimmock

vimmock is a module that makes testing Python code using vim module much easier.

Usage

At the test environment initialization one should prepare vim object that would normaly be used within vim's plugin. We have added convenient function for that:

import vimmock
vimmock.patch_vim()

This is equivalent to:

import sys
from vimmock import VimMock

sys.modules['vim'] = VimMock()

Once this is done one can start importing vim module which would be instance of VimMock class. From now on we can write our tests (and import vim module):

import vim
import unittest
import myplugin

class TestPlugin(unittest.TestCase):

    def setUp(self):
        vim.setup_text('\n'.join(('foo', 'bar')))

    def test_simple(self):
        vim.current.window.cursor = 2, 0 # rows starts from 1, column from 0
        # ... let's assume our plugin swaps lines
        self.assertEqual(vim.current.buffer[0], 'bar')
        self.assertEqual(vim.current.buffer[1], 'foo')

Development

Please use github's issue tracker for filing new issues. Preferred way of attaching patches is via pull requests.

Work in progress

Please note that vimmock is a work-in-progress module. Only basic mocks are actually completed. If you want to use this module for now it is best if you fork it, link to your PYTHONPATH environment variable and modify on the fly. Pull requests are welcome!
