+description: |
+  [Testcontainers](https://www.testcontainers.org/) is a Java library that supports JUnit tests, providing lightweight,
+  throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.
+rationale: |
+  Testcontainers make the following kinds of tests easier:
+    Data access layer integration tests: use a containerized instance of a MySQL,
+    PostgreSQL or Oracle database to test your data access layer code for complete compatibility,
+    but without requiring complex setup on developers' machines and safe in the knowledge that your
+    tests will always start with a known DB state.
+    Any other database type that can be containerized can also be used.
+
+    Application integration tests: for running your application in a short-lived test mode with dependencies,
+    such as databases, message queues or web servers.
+
+    UI/Acceptance tests: use containerized web browsers, compatible with Selenium, for conducting automated UI tests.
+    Each test can get a fresh instance of the browser, with no browser state,
+    plugin variations or automated browser upgrades to worry about.
+    And you get a video recording of each test session, or just each session where tests failed.
