gconv覆盖率统计工具

1） gcc -fprofile-arcs -ftest-coverage -o test test.c

2）./test 运行生成test.gcda

3）gcov test.c

File 'test.c'

Lines executed:87.50% of 8

test.c:creating 'test.c.gcov'

4）通过lcov生成html可视化结果

#!/bin/sh

OUTPUT_DIR=/some/path

if (! test -d $OUTPUT_DIR )

then

echo "Missing path: $OUTPUT_DIR"

exit 1

fi

make clean || exit 1

export LDFLAGS="-lgcov"

export CPPFLAGS="-fprofile-arcs -ftest-coverage"

make || exit 1

lcov -c -i -d . -o .coverage.base

lcov -c -d . -o .coverage.run

lcov -d . -a .coverage.base -a .coverage.run -o .coverage.total

genhtml --no-branch-coverage -o $OUTPUT_DIR .coverage.total

rm -f .coverage.base .coverage.run .coverage.total
