# Tests
## Running Tests
`go test` is used for testing. A running PostgreSQL
server is required, with the ability to log in. The
database to connect to test with is "pqgotest," on
"localhost" but these can be overridden using [environment
variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
Example:
PGHOST=/run/postgresql go test
## Benchmarks
A benchmark suite can be run as part of the tests:
go test -bench .
## Example setup (Docker)
Run a postgres container:
```
docker run --expose 5432:5432 postgres
```
Run tests:
```
PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
```
