Is it possible to post coverage for multiple packages to Coveralls?
Taking Usman's answer, and altering it to support skipping Godep and other irrelevant folders:
echo "mode: set" > acc.out
for Dir in $(go list ./...);
do
returnval=`go test -coverprofile=profile.out $Dir`
echo ${returnval}
if [[ ${returnval} != *FAIL* ]]
then
if [ -f profile.out ]
then
cat profile.out | grep -v "mode: set" >> acc.out
fi
else
exit 1
fi
done
if [ -n "$COVERALLS_TOKEN" ]
then
goveralls -coverprofile=acc.out -repotoken=$COVERALLS_TOKEN -service=travis-pro
fi
rm -rf ./profile.out
rm -rf ./acc.out
Notice that instead of looking at every directory, I us the go list ./...
command which lists all directories that actually get used to build the go package.
Hope that helps others.
** EDIT **
If you are using the vendor
folder for Go v.1.6+ then this script filters out the dependencies:
echo "mode: set" > acc.out
for Dir in $(go list ./...);
do
if [[ ${Dir} != *"/vendor/"* ]]
then
returnval=`go test -coverprofile=profile.out $Dir`
echo ${returnval}
if [[ ${returnval} != *FAIL* ]]
then
if [ -f profile.out ]
then
cat profile.out | grep -v "mode: set" >> acc.out
fi
else
exit 1
fi
else
exit 1
fi
done
if [ -n "$COVERALLS_TOKEN" ]
then
goveralls -coverprofile=acc.out -repotoken=$COVERALLS_TOKEN -service=travis-pro
fi
Has anyone figured out how to get coverage for multiple packages?
Note: with Go 1.10 (Q1 2018), that... will actually be possible.
See CL 76875
cmd/go
: allow-coverprofile
with multiple packages being tested
You can see the implementation of a multiple package code coverage test in commit 283558e
Jeff Martin has since the release of Go 1.10 (Feb. 2018) confirmed in the comments:
go test -v -cover ./pkgA/... ./pkgB/... -coverprofile=cover.out
gets a good profile andgo tool cover -func "cover.out"
will get atotal: (statements) 52.5%
.
So it is working!
I ended up using this script:
echo "mode: set" > acc.out
for Dir in $(find ./* -maxdepth 10 -type d );
do
if ls $Dir/*.go &> /dev/null;
then
go test -coverprofile=profile.out $Dir
if [ -f profile.out ]
then
cat profile.out | grep -v "mode: set" >> acc.out
fi
fi
done
goveralls -coverprofile=acc.out $COVERALLS
rm -rf ./profile.out
rm -rf ./acc.out
It basically finds all the directories in the path and prints a coverage profile for them separately. It then concatenates the files into one big profile and ships them off to coveralls.
