PostgreSQL

Need to have a running PostgreSQL database to run the tests. To do that run it in the package level test main function.

Our test package has Main function it will run the given function and accept a defer function for cleanup.

package container_test

import (
	"testing"

	"github.com/stretchr/testify/require"
	"github.com/stretchr/testify/suite"
	"github.com/worldline-go/test/container"
)

type PostgresSuite struct {
	suite.Suite
	container *container.PostgresContainer
}

func (s *PostgresSuite) SetupSuite() {
	s.container = container.Postgres(s.T())
}

func TestExampleTestSuite(t *testing.T) {
	suite.Run(t, new(PostgresSuite))
}

func (s *PostgresSuite) TearDownSuite() {
	s.container.Stop(s.T())
}

func (s *PostgresSuite) SetupTest() {
	s.container.ExecuteFiles(s.T(), []string{"testdata/init.sql"})
}

func (s *PostgresSuite) TearDownTest() {
	sql := "Drop schema if exists transaction cascade;"
	_, err := s.container.Sqlx().Exec(sql)
	require.NoError(s.T(), err)
