MySQL, Node & Testcontainers Testing Done Right
summary
Shows using Testcontainers to spin a throwaway MySQL Docker instance with one line (new MySQLContainer().start()), the Node built-in test runner to run suites, and the MySQL X DevAPI + Faker to insert and verify data; demo creates a user table via a DDL script, runs two tests (container check and create-user) that take ~69ms and ~23ms, and cleanly shuts the container down. Emphasizes isolated test database per suite, avoid hard‑coded values, and using a separate data‑utils SQL check rather than the production repository code.
