The aim of the project is:

• Display coverage information in SignColumn
• Go to next uncovered chunk of code
• Show tests where current line was executed (pytest only)

Features in action:

For vim-plug

if has('nvim')
    Plug 'kalekseev/vim-coverage.py', { 'do': ':UpdateRemotePlugins' }
else
    Plug 'kalekseev/vim-coverage.py'
    Plug 'roxma/nvim-yarp'
    Plug 'roxma/vim-hug-neovim-rpc'
endif

Editor must be started inside python virtualenv where coverage package installed otherwise plugin will try to load global coverage module or fail.

• CoveragePy - show coverage signs for current buffer
• CoveragePyToggle - show / hide coverage
• CoveragePytestContext - show tests where current line was executed. Requires py.test and --cov-context=test option.
• CoveragePyNext - go to next not covered chunk
