Project Setup

Docker

• Install Docker for Mac

• Setup and boot the Docker containers:

./bin/envsetup.sh

Development

• Setup the databases:

  • Postgres:

  rake db:setup

• Run the Rails app

foreman start -f Procfile.dev

Tests

Docker-based tests on the CI server

Add the following build settings to run the tests in the Docker environment via Docker Compose (configuration in docker-compose.test.yml):

• Configure the environment variable BRANCH_TAG to tag Docker images per branch:

export BRANCH_TAG=$SEMAPHORE_BRANCH_ID

Each branch needs to have its own Docker image to avoid build settings disparities and leverage Docker image caching.

BRANCH_TAG must not contain special characters (/) to be valid. So using $BRANCH_NAME will not work e.g. chore/setup-docker. An alternative is to use a unique identifier such as PR_ID or BRANCH_ID on the CI server.

• Pull the latest version the Docker image for the branch:

docker pull $DOCKER_IMAGE:$BRANCH_TAG || true

On each build, the CI environment does not contain yet a cached version of the image. Therefore, it is required to pull it first to leverage the cache_from settings of Docker Compose which avoids rebuilding the whole Docker image on subsequent test builds.

• Build the Docker image:

docker-compose -f docker-compose.test.yml build

Upon the first build, the whole Docker image is built from the ground up and tagged using $BRANCH_TAG.

• Push the latest version of the Docker image for this branch:

docker push $DOCKER_IMAGE:$BRANCH_TAG

• Setup the test database:

docker-compose -f docker-compose.test.yml run test bin/bundle exec rake db:test:prepare

Test

• Run all tests:

docker-compose -f docker-compose.test.yml run test

• Run a specific test:

docker-compose -f docker-compose.test.yml run test bin/bundle exec spec [rspec-params]

Automated Code Review Setup

• Make sure that the config file pronto.yml for pronto has been added as a configuration file.

• In the CI build script, add the following command:

if ([ $BRANCH_NAME != 'master' ] && [ $BRANCH_NAME != 'development' ]); then \ 
  (echo "Running pronto"; bundle exec pronto run -f bitbucket_pr -c origin/development);  else \ (echo "Escaping pronto"); \
