qtpy.vim

A simple way of running python unit tests from within VIM based on the cursor location.

Useful for receiving immediate feedback as you write tests, despite what test runner or framework your project uses to run its tests.

Usage

To use this plugin, make sure ftplugins are enabled, via "filetype on" in your .vimrc.

Whenever a command is triggered a small message displays informing you that the plugin is running a certain action. In the above call, you would see something like this:

Running tests for class

When tests are successful a green bar appears. If you have any number of fails you get a red bar with a line-by-line list of line numbers and errors.

Run all tests in current file:

:QTPY file

Run all tests in current class:

:QTPY class

Run current test at cursor location:

:QTPY method

If you would like to see the complete qtpy output you can add an optional verbose flag to any of the commands for qtpy. For the previous command, it would look like:

:QTPY class verbose

This would open a split scratch buffer that you can fully interact with. You can close this buffer with ':wq' or you can hit 'q' at any moment in that buffer to close it.

The previous test session display can be toggled with:

:QTPY session

If for some reason you need to reset and clear all global variables that affect the plugin you can do so by running the following command:

:QTPY clear

Configuration

qtpy is configured to work with nosetests by default, however, using qtpy with other unit tests runners is simple. Just set the necessary variables in your vimrc.

For example, insert these lines into your .vimrc to use QTPY with Py.Test:

" for use with Py.Test
let g:qtpy_shell_command = "py.test --tb=short"
let g:qtpy_class_delimiter = "::"
let g:qtpy_method_delimiter = "::"

The delimiter variables are used with constructing the test path to pass into the test runner. Such as "py.test /testfolder/testfile.py::TestClass::TestMethod" for the example above where the first '::' is the class_delimiter and the second is the method_delimiter

I recommend mapping keys to qtpy commands for easy running. To do so, insert commands like this into your .vimrc:

" QTPY
au FileType python nnoremap <F8> :QTPY method verbose<CR>
au FileType python nnoremap <F9> :QTPY session<CR>

au FileType python nnoremap <silent><Leader>c <Esc>:QTPY class verbose<CR>

The 'au FileType python' ensures these mappings only occur in a python file.

Shell Support

This plugin provides a way to have a better shell experience when running verbose flag by using the Conque.vim plugin. If you have this most excellent piece of Vim plugin (see: http://www.vim.org/scripts/script.php?script_id=2771) then qtpy.vim will use that instead of Vim's own dumb shell environment.
