# PostgreSQL ADBC Driver Validation Suite

This directory contains a Python-based validation suite for the PostgreSQL ADBC driver.

## Testing

A running instance of PostgreSQL is required.  For example, using Docker:

```shell
$ docker run -it --rm \
    -e POSTGRES_PASSWORD=password \
    -e POSTGRES_DB=postgres \
    -p 5432:5432 \
    postgres
```

Alternatively use the `docker compose` provided by ADBC to manage the test
database container.

```shell
$ docker compose up postgres-test
# When finished:
# docker compose down postgres-test
```

Then, to run the tests, set the environment variable specifying the
PostgreSQL URI before running tests:

```shell
$ export ADBC_POSTGRESQL_TEST_URI=postgresql://localhost:5432/postgres?user=postgres&password=password
```

### 5. Run Tests

#### Using pixi:

```bash
cd c/driver/postgresql/validation
pixi run validate
```
