test.afterEach(t => db.teardown(t.context))

test('some that needs a db!', async t => {
  t.is(t.context.dbConfig.username, 'postgres', 'has default postgres user')
  const containerData = await t.context.dbContainer.inspect()
  t.truthy(containerData.Image, 'has docker image')
  t.is(containerData.State.Status, 'running', 'db is running')
  t.is(Object.keys(containerData.HostConfig.PortBindings).length, 1, 'has host port exposed')
