**TLDR**
Add unit and integration tests to Billing. First approach to run jest
integration tests directly from VSCode.
**In order to run the unit tests:**
Run unit test using the CLI or with the jest extension directly from
VSCode.
**In order to run the integration tests:**
Ensure that your database has the billingTables. If that's not the case,
migrate the database with IS_BILLING_ENABLED set to true:
` npx nx run twenty-server:test:integration
test/integration/billing/suites/billing-controller.integration-spec.ts`
**Doing:**
- Unit test on transformSubscriptionEventToSubscriptionItem
- More tests cases in billingController integration tests.
