Use the Nix development shell before running project commands:

```sh
nix develop
```

In another terminal, start the local PostgreSQL service before running the
DB-backed test suite:

```sh
nix run .#services
```

The dev shell exports:

```sh
DATABASE_URL=postgres://127.0.0.1:5432/apalis_diesel_postgres
```

If you only need to run the non-database unit tests, unset `DATABASE_URL`:

```sh
env -u DATABASE_URL cargo test --locked --all-features --lib
```
