Requirements

• Java 17
• Maven >= 3.2.1
• Docker >= 3.0 (for database and integration tests)

Clone repository and build project

In this repository are different database test examples. A fast unit test and a slow integration tests.

For further information and the difference between unit and integration tests see Youtube (German) or GitHub.

Unit test de.larmic.postgres.database.TweetRepositoryTest will be started in maven phase test. Integrations test de.larmic.postgres.database.TweetRepositoryIT will be started in maven phase verify.
