lcov to cobertura XML converter

This project does as the name implies: it converts code coverage report files in lcov format to Cobertura's XML report format so that CI servers like Jenkins can aggregate results and determine build stability etc.

Coverage metrics supported:

• Package/folder overall line and branch coverage
• Class/file overall line and branch coverage
• Functions hit
• Line and Branch hits

Quick usage

Grab it raw and run it with python:

python lcov_cobertura.py lcov-file.dat

• -b/--base-dir - (Optional) Directory where source files are located. Defaults to the current directory
• -e/--excludes - (Optional) Comma-separated list of regexes of packages to exclude
• -o/--output - (Optional) Path to store cobertura xml file. Defaults to ./coverage.xml
• -d/--demangle - (Optional) Demangle C++ function names. Requires c++filt

python lcov_cobertura.py lcov-file.dat --base-dir src/dir --excludes test.lib --output build/coverage.xml --demangle

With pip:

pip install lcov_cobertura

Command-line usage

lcov_cobertura lcov-file.dat

• -b/--base-dir - (Optional) Directory where source files are located. Defaults to the current directory
• -e/--excludes - (Optional) Comma-separated list of regexes of packages to exclude
• -o/--output - (Optional) Path to store cobertura xml file. Defaults to ./coverage.xml
• -d/--demangle - (Optional) Demangle C++ function names. Requires c++filt

Usage as a Python module

Use it anywhere in your python:

from lcov_cobertura import LcovCobertura

LCOV_INPUT = 'SF:foo/file.ext\nDA:1,1\nDA:2,0\nend_of_record\n'
converter = LcovCobertura(LCOV_INPUT)
cobertura_xml = converter.convert()
print(cobertura_xml)
