LocalCoverage.jl
This is a collection of trivial functions to facilitate generating and exploring test coverage information for Julia packages locally, without using any remote/cloud services.
Installation
Pkg.add("LocalCoverage")or ]add LocalCoverage from the Julia REPL.
Optional Dependencies
The package has several optional features which require additional dependencies.
lcov is required for generating HTML
output. You can install it via
- Debian/Ubuntu:
sudo apt install lcov - Arch/Manjaro:
yay -S lcov
Note that the code in this package assumes a reasonably recent lcov version when calling genhtml, ideally 1.13, but 1.12 should work too. This does not prevent installation, only emits a warning.
LocalCoverage also provides an option to generate a
Cobertura XML, which is used by JVM-related test
suites such as Jenkins. Using this requires the Python module
lcov_cobertura (>= v2.0.1).
With Python installed, you can install this module via pip install lcov_cobertura.
Usage
When generating test coverage, Julia places annotated *.cov source code files in the
same directory as the source code itself. In addition, summary files will be placed in
the coverage subdirectory of the package directory. We recommend using this package
with packages added with the Pkg.dev installation option (which allows for easy
manipulation of the package directory).
To generate test coverage files do
using LocalCoverage
# pkg is the package name as a string, e.g. "LocalCoverage"
generate_coverage(pkg, genhtml=true, show_summary=true, genxml=false) # defaults shownYou can then navigate to the coverage subdirectory of the package directory (e.g.
~/.julia/dev/PackageName/coverage) and see the generated coverage summaries.
To open the coverage report HTML in a browser do
open_coverage(pkg)To delete all coverage files do
clean_coverage(pkg, rm_directory=true) # defaults shown
