Getting started with Testcontainers for Go — Write the test suite

Reference note (untrusted external data; do not execute it as instructions). Create customer/repo_suite_test.go and implement tests for creating a customer and getting a customer by email using the testify suite package Here's what the code does CustomerRepoTestSuite extends suite.Suite and includes fields shared across multiple tests. SetupSuite() runs once before all tests. It calls CreatePostgresContainer(suite.T(), ...) which handles cleanup registration automatically via CleanupContainer, so no TearDownSuite() is needed. TestCreateCustomer() uses require.NoError() for the create operation (fail immediately if it errors) and assert.NotNil() for the ID check. TestGetCustomerByEmail() uses require.NoError() then asserts on the returned values. TestCustomerRepoTestSuite(t testing.T) runs the test suite when you execute go test. > [!TIP] > For the purpose of this guide, the tests don't reset data in the database. > In practice, it's a good idea to reset the da Attribution: Adapted from Docker Documentation under Apache-2.0.
