ECoveralls

Coveralls reports for Erlang projects.

Status

This is alpha software. Things might still change in ways that break everything.

Usage

This is currently only known to work with erlang.mk, Common Test and Travis CI.

cover.spec

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.

erlang.mk

Just add ECoveralls as a testing dependency.

TEST_DEPS = ecoveralls
dep_ecoveralls = git https://github.com/nifoc/ecoveralls master

If 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
endif

Your CT_OPTS have to reference the cover.spec file.

CT_OPTS = -cover ./test/cover.spec

Travis CI

Add 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-report

If 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-report
