### Federation
-This will run 3 nodes:
+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
+$ createdb -O peertube peertube_test{1,2,3}
+```
+
+Build the application and flush the old tests data:
```
$ npm run build
$ npm run clean:server:test
+```
+
+This will run 3 nodes:
+
+```
$ npm run play
```
Then you will get access to the three nodes at `http://localhost:900{1,2,3}`
with the `root` as username and `test{1,2,3}` for the password.
+Instance configurations are in `config/test-{1,2,3}.yaml`.
### Unit tests
-To run unit tests, you need to build the application first:
+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
+$ createdb -O peertube peertube_test{1,2,3,4,5,6}
+```
+
+Build the application and run the unit/integration tests:
```
$ npm run build
$ 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.
