Coveralls reports for Erlang projects.
This is alpha software. Things might still change in ways that break everything.
This is currently only known to work with erlang.mk, Common Test and Travis CI.
In order to have one .coverdata file that includes all test suites it is recommended to add the following line to your cover.spec:
{export, "logs/all.coverdata"}.This will write an all.coverdata file to your logs directory, which is what Common Test uses by default.
Just add ECoveralls as a testing dependency.
TEST_DEPS = ecoveralls
dep_ecoveralls = git https://github.com/nifoc/ecoveralls masterIf you only want to depend on ECoveralls when tests are running on Travis CI, you can do something like the following instead:
ifeq ($(USER),travis)
TEST_DEPS += ecoveralls
dep_ecoveralls = git https://github.com/nifoc/ecoveralls master
endifYour CT_OPTS have to reference the cover.spec file.
CT_OPTS = -cover ./test/cover.specAdd the following target to your Makefile (after the erlang.mk include):
coverage-report: $(shell ls -1rt `find logs -type f -name \*.coverdata 2>/dev/null` | tail -n1)
$(gen_verbose) erl -noshell -pa ebin deps/*/ebin -eval 'ecoveralls:travis_ci("$?"), init:stop()'
.PHONY: coverage-reportIf you're not using erlang.mk you should replace $(gen_verbose) with @.
Now you have to tell Travis to send data to Coveralls after a (successful) test run. You can do this by adding the following lines to your .travis.yml:
after_success:
- make coverage-reportISC.
