#### Prebuilt container
Since configuring PostgreSQL can be fiddly, we can make use of a pre-made
Docker container to set up PostgreSQL and run our tests for us. To do so, run
```shell
scripts-dev/test_postgresql.sh
```
Any extra arguments to the script will be passed to `tox` and then to `trial`,
so we can run a specific test in this container with e.g.
```shell
scripts-dev/test_postgresql.sh tests.replication.test_sharded_event_persister.EventPersisterShardTestCase
```
The container creates a folder in your Synapse checkout called
`.tox-pg-container` and uses this as a tox environment. The output of any
`trial` runs goes into `_trial_temp` in your synapse source directory — the same
as running `trial` directly on your host machine.
## Run the integration tests ([Sytest](https://github.com/matrix-org/sytest)).
The integration tests are a more comprehensive suite of tests. They
