What are some examples of using Testcontainers with Spring Boot?

Can you give me some examples of using Testcontainers with Spring Boot?

Sure! Testcontainers is a Java library that helps with integration testing by providing lightweight, throwaway instances of common databases and other services. For example, you can use Testcontainers to spin up a PostgreSQL database for your Spring Boot application during tests.

How do I set up Testcontainers in my Spring Boot project?

To set up Testcontainers, you need to add the Testcontainers dependency to your pom.xml or build.gradle file. For Maven, you can add: <dependency><groupId>org.testcontainers</groupId><artifactId>testcontainers</artifactId><version>1.16.0</version></dependency>.

Can you show me a code example for a test using Testcontainers?

Absolutely! Here's a simple example:

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.testcontainers.containers.PostgreSQLContainer;

@SpringBootTest
public class MyServiceTest {
    static PostgreSQLContainer<?> postgres = new PostgreSQLContainer<>();

    static {
        postgres.start();
    }

    @Test
    void testMyService() {
        // Your test code here, using postgres.getJdbcUrl() for database connection
    }
}
