A plugin for Sublime Text 2/3 that can highlight lines of Python lacking test coverage, based on the output of Ned Batchelder's coverage.py, based on the original plugin for ST2, SublimePythonCoverage.
Set up Sublime Package Control if you don't have it yet.
Go to Tools > Command Palette.
Type Package Control: Install Package
and hit enter.
Type PyCover
and hit enter.
PyCover relies on the external coverage.py package, which you can install with
pip install coverage
Toggle missing line highlights by running the show_python_coverage
command,
bound to ctrl+alt+shift+c
by default.
You can also access it with the Command Palette under "Toggle Uncovered Lines",
or via the right-click menu.
With the settings option "onload": true
,
PyCover will start highlighting missing lines as soon as your file loads.
The highlight_uncovered_lines
option is used to toggle highlighting of uncovered lines.
When this option is set to true
, uncovered lines are highlighted in both editor window and minimap.
However, this can be disruptive to the experience for some users, so by default this option is set to false
.
PyCover works by looking in all parent directories of the active file
until it finds a .coverage
file (as produced by coverage.py
).
Obviously, it only works if that file exists
and contains coverage information for the file you opened.
Once the .coverage
file is found, PyCover invoke the coverage
module
with system Python (see the 'python' settings option to change this)
and highlights any missing lines with a gutter mark.
