|
|
# for testing purposes. The raw collected data can be converted to .gcov files
|

# with the command "gcov build/temp.linux-x86_64-3.4/src/gmpy2.gcno". To create
|
|
# a tidy HTML summary, use "gcovr -s -r . --html -o coverage.html". When tests
|
|
# are completed, delete the .gcov and coverage.html files.
|
|
#
|
|
# The following commands show the use of lcov to analyze the coverage data.
|
|
#
|
|
# py34 setup.py clean
