Usage

Recommended: In a TestXxx function

package foo_test

import (
	"testing"

	"github.com/adrianbrad/psqldocker"
)

func TestXxx(t *testing.T) {
    const schema = "CREATE TABLE users(user_id UUID PRIMARY KEY);"
	
    c, err := psqldocker.NewContainer(
        "user",
        "password",
        "dbName",
        psqldocker.WithContainerName("test"), 
        // initialize with a schema
        psqldocker.WithSql(schema),
        // you can add other options here
    )
    if err != nil {
        t.Fatalf("cannot start new psql container: %s\n", err)
    }
	
    t.Cleanup(func() {
        err = c.Close()
        if err != nil {
            t.Logf("err while closing conainter: %w", err)
        }
    })
	
    t.Run("Subtest", func(t *testing.T) {
        // execute your test logic here 
    })
}

In a TestMain function

package foo_test

import (
	"log"
	"testing"

	"github.com/adrianbrad/psqldocker"
)

func TestMain(m *testing.M) {
    const schema = "CREATE TABLE users(user_id UUID PRIMARY KEY);"

    c, err := psqldocker.NewContainer(
        "user",
        "password",
        "dbName",
        psqldocker.WithContainerName("test"), 
        // initialize with a schema
        psqldocker.WithSql(schema),
        // you can add other options here
    )
    if err != nil {
        log.Fatalf("cannot start new psql container: %s\n", err)
    }
	
    defer func() {
        err = c.Close()
        if err != nil {
            log.Printf("err while closing conainter: %w", err)
        }
    }() 
	
    m.Run()
}
