Spring Time in Kotlin, Episode 5: Integration testing with TestContainers

This is a demo project used in the 5th episode of Spring Time in Kotlin series at the official Kotlin YouTube channel

In this episode:

• We start using PostgreSQL database instead of H2
• Use TestContainers for testing
• Lean more about Kotlin and Java interoperability

##Running the application

First, start PostgreSQL database by running this command (assuming you have Docker installed on the machine):

docker run -e POSTGRES_PASSWORD=password -e POSTGRES_USER=sa -p 5432:5432 -d postgres

Now you can launch Spring Boot application:

./gradlew bootRun
