• export AUTH0_URL=https://topcoder-dev.auth0.com/oauth/token
• export AUTH0_AUDIENCE=https://m2m.topcoder-dev.com/

Also properly configure AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, ATTACHMENT_S3_BUCKET, IS_LOCAL_DB config parameters.

Test configuration is at config/test.js. You don't need to change them. The following test parameters can be set in config file or in env variables:

• ADMIN_TOKEN: admin token
• COPILOT_TOKEN: copilot token
• USER_TOKEN: user token
• EXPIRED_TOKEN: expired token
• INVALID_TOKEN: invalid token
• M2M_FULL_ACCESS_TOKEN: M2M full access token
• M2M_READ_ACCESS_TOKEN: M2M read access token
• M2M_UPDATE_ACCESS_TOKEN: M2M update (including 'delete') access token
• S3_ENDPOINT: endpoint of AWS S3 API, for unit and e2e test only; default to localhost:9000

AWS S3 Setup

Go to https://console.aws.amazon.com/ and login. Choose S3 from Service folder and click Create bucket. Following the instruction to create S3 bucket.

Local services setup

In the local folder, run docker-compose up It starts Elasticsearch, DynamoDB and S3 compatible server.

Mock api

For postman verification, please use the mock api under mock-api folder. It provides mock endpoint to fetch challenge resources and groups. You need to ensure DynamoDB configuration in mock-api/config/default.js is consistent with config/default.js Go to mock-api folder and run command npm run start to start the mock-api listening on port 4000

Create Tables

1. Make sure DynamoDB are running as per instructions above.
2. Make sure you have configured all config parameters. Refer Configuration
3. Run npm run create-tables to create tables.

Scripts

1. Drop/delete tables: npm run drop-tables
2. Creating tables: npm run create-tables
3. Seed/Insert data to tables: npm run seed-tables
4. Initialize/Clear database in default environment: npm run init-db
5. View table data in default environment: npm run view-data <ModelName>, ModelName can be Challenge, ChallengeType, ChallengeSetting, AuditLog, Phase, TimelineTemplateor Attachment
6. Create Elasticsearch index: npm run init-db, or to re-create index: npm run init-db force
7. Synchronize ES data and DynamoDB data: npm run sync-es

Notes

• The seed data are located in src/scripts/seed

Local Deployment

• Install dependencies npm install
• Run lint npm run lint
• Run lint fix npm run lint:fix
• initialize Elasticsearch, create configured Elasticsearch index if not present: npm run init-es, or re-create the index: npm run init-es force
• Create tables npm run create-tables
• Clear and init db npm run init-db
• Start app npm start
• App is running at http://localhost:3000
• Start mock-api, go to mock-api folder and npm start, mock api is running at http://localhost:4000

Running tests

Prepare

• Start Local services.
• Start Mock API.
• Create DynamoDB tables.
• Initialize ES index.
• Various config parameters should be properly set.

Seeding db data is not needed.

Running unit tests

To run unit tests alone

npm run test

To run unit tests with coverage report

npm run test:cov

Running integration tests

To run integration tests alone

npm run e2e

To run integration tests with coverage report

npm run e2e:cov

Verification

Refer to the verification document Verification.md

Notes

• after uploading attachments, the returned attachment ids should be used to update challenge; finally, attachments have challengeId field linking to their challenge, challenge also have attachments field linking to its attachments, this will speed up challenge CRUDS operations.

• In the app-constants.js Topics field, the used topics are using a test topic, the suggested ones are commented out, because these topics are not created in TC dev Kafka yet.
