SpringBoot Integration-Test sample 🐳

Kotlin(1.6.10) + Spring Boot 2.6.2 + Testcontainers(PostgreSQL) + MyBatis + DbUnit + Spring Security + JWT auth + Flyway
(prototype for myself)

Features

• I wrote this for myself because there was not enough good sample code for testing SpringBoot using Testcontainers.🐳
• The implementation focuses on how to use TestContainer in SpringBoot tests, and the rest is not implemented tightly. (e.g. Mapper called in RestController)
• Postgres container is reused. (Booting once)
• As an added bonus, the user authentication uses JWT (JSON Web Token), and we created a sample Spring Security Test.

datasource.apply {
    url = container.jdbcUrl
    username = container.username
    password = container.password
    setDriverClassName(container.driverClassName)
}

There are several ways to implement this way of overwriting Properties, but I felt it was too cumbersome, so I decided to implement the datasource generation.

System.setProperty("DB_URL", container.jdbcUrl)
System.setProperty("DB_USERNAME", container.username)
System.setProperty("DB_PASSWORD", container.password)
