Vim pytest compiler (with traceback support)

Purpose

This compiler parses all lines of a traceback that contains file paths, so that you can easily jump up and down the call stack with the usual vim commands that you use to jump through the location list. This is most useful when looking only at a single test failure (e.g. when pytest is called with -x).

Installation

Use your favorite vim plugin manager to install karlb/vim-pytest-traceback or copy compiler/pytest.vim to the directory with you vim compiler files (e.g. .vim/compiler).

Usage

Plain vim

Enable the compiler with :compiler pytest, then run :make with any additional parameters you want to pass to pytest.

dispatch.vim

If you use Tim Pope's dispatch.vim, the compiler will automatically be used when you use Dispatch pytest to run pytest.

test.vim Configuration

If you use it together with test.vim, you want to configure pytest to use short tracebacks:

let test#python#pytest#options = '-Wignore --tb=short -q'
