+
+### Unit tests
+
+Create a PostgreSQL user **with the same name as your username** in order to avoid using the *postgres* user.
+
+Then, we can create the databases (if they don't already exist):
+
+```
+$ sudo -u postgres createuser you_username --createdb --superuser
+$ npm run clean:server:test
+```
+
+Build the application and run the unit/integration tests:
+
+```
+$ npm run build -- --light
+$ npm test
+```
+
+If you just want to run 1 test:
+
+```
+$ npm run mocha -- --exit --require ts-node/register/type-check --bail server/tests/api/index.ts
+```
+
+Instance configurations are in `config/test-{1,2,3,4,5,6}.yaml`.
+Note that only instance 2 has transcoding enabled.
