Courier Build Status Coverage Status Go Report Card

Install Courier in your workspace with:

go get github.com/nyaruka/courier

Build Courier with:

go install github.com/nyaruka/courier/cmd/...

This will create a new executable in $GOPATH/bin called courier.

To run the tests you need to create the test database:

$ createdb courier_test
$ createuser -P -E courier
$ psql -d courier_test -f backends/rapidpro/schema.sql
$ psql -d courier_test -c "GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO courier;"
$ psql -d courier_test -c "GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO courier;"

To run all of the tests including benchmarks:

go test $(go list ./... | grep -v /vendor/) -cover -bench=.
