Getting Started

Prerequisites

• Ruby version: 3.0.1
• Node version: 16.13.2

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

./bin/dev

Testing

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, e.g:

# a unique `BRANCH_TAG` value to tag the Docker image
# e.g $SEMAPHORE_BRANCH_ID or using the
# or using nimblehq/branch-tag-action@v1.2 Github action
export BRANCH_TAG= # unique value for tagging Docker image

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:

./bin/docker-prepare && 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 way
docker compose -f docker-compose.test.yml run test

# Non-Docker way
rspec

• Run a specific test:

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

# Non-Docker way
rspec [rspec-params]

Automated Code Review Setup

• Add a bot (i.e. team-nimblehq) to this repository or to the organization. The bot requires permission level “Write” to be able to set a PR’s status.

• Create a Personal Access Token from bot account with public_repo scope, and set it as DANGER_GITHUB_API_TOKEN secret on the CI Environment Settings.

CI/CD

The project relies entirely on Github Actions for CI/CD via multiple workflows located under the .github/workflows/ directory.

Please check out the .github/workflows/README.md file for further instructions.
