testcontainers-postgresql

A Haskell library providing Testcontainers integration for PostgreSQL databases. This library simplifies running PostgreSQL containers for testing purposes, with support for various PostgreSQL versions and authentication methods.

Features

• Multiple PostgreSQL Versions: Support for PostgreSQL versions 9 through 17
• Flexible Authentication: Choose between trust-based authentication or username/password credentials
• Log Forwarding: Optional log forwarding to the console for debugging

Quick Start

import TestcontainersPostgresql
import TestcontainersPostgresql.Configs.Config
import TestcontainersPostgresql.Configs.Distro
import TestcontainersPostgresql.Configs.Auth

main :: IO ()
main = do
  let config = Config
        { forwardLogs = True
        , distro = Distro16  -- PostgreSQL 16
        , auth = TrustAuth   -- Trust-based authentication
        }

  run config $ \(host, port) -> do
    putStrLn $ "PostgreSQL is running at " ++ show host ++ ":" ++ show port
    -- Your test code here
    -- Connect to PostgreSQL using host and port
