[DevOps] Deploy develop to a cloudgov environment after PR merge

[jtimpe]

Description:
After PRs merge we should

• build and deploy the application/services to a development environment (bonus points for storing the build artifacts for later deployment to production)
• run end-to-end tests against the deployed application

Acceptance Criteria:
Create a list of functional outcomes that must be achieved to complete this issue

• develop deploys to [a cloudgov environment] when PRs merge
• cypress tests run against [the cloudgov environment] once a deployment completes
  • run tests after deployment to any environment? dev, staging, qasp, etc (not prod)
• Testing Checklist has been run and all tests pass
• README is updated, if necessary

Tasks:
Create a list of granular, specific work items that must be completed to deliver the desired outcomes of this issue

• Modify the Circle CI config to deploy the develop branch to [a development environment in cloudgov] after PRs merge
• Add a step post-deployment to run the cypress e2e tests against [the environment].
  • This requires overriding some environment variables in the cypress run command, as well as adding a CYPRESS_TOKEN environment variable to the Circle CI config and CloudGov app variables.
  • example ci job:

    TANF-app/.circleci/build-and-test/jobs.yml

    Lines 44 to 65 in be8197a

    	test-e2e:
    	executor: machine-executor
    	working_directory: ~/tdp-apps
    	steps:
    	- checkout
    	- docker-compose-check
    	- docker-compose-up-backend
    	- docker-compose-up-frontend
    	- install-nodejs-machine
    	- disable-npm-audit
    	- install-nodejs-packages:
    	app-dir: tdrs-frontend
    	- run:
    	name: Set up cypress test users
    	command: cd tdrs-backend; docker-compose exec web python manage.py generate_cypress_users
    	- run:
    	name: Run Cypress e2e tests
    	command: cd tdrs-frontend; npm run test:e2e-ci
    	- store_artifacts:
    	path: tdrs-frontend/cypress/screenshots/
    	- store_artifacts:
    	path: tdrs-frontend/cypress/videos/

  • example of overriding env vars in cypress run:

    TANF-app/tdrs-frontend/package.json

    Line 41 in be8197a

    "test:e2e-ci": "cypress run --headless --env cypressToken=${CYPRESS_TOKEN}",

  • [update with link to example config once cypress PR merges]
• Update devops/application documentation to reflect the change in process
• Run Testing Checklist and confirm all tests pass
