# Technologies Utilized

The code for DS can be found in the [pass-support repository](https://github.com/eclipse-pass/pass-support/tree/main/pass-deposit-services).

DS is a backend service that is written in [Java](https://www.java.com/en/) and [Spring Boot](https://spring.io/projects/spring-boot). The DS project is a [Maven](https://maven.apache.org/) project, which is used to execute the standard lifecycle tasks for software development (i.e. build/test/package/release) of the DS service. The Maven POM is a child of the [`eclipse-pass/pass-support` POM](https://github.com/eclipse-pass/pass-support) which is a child of the [`eclipse-pass/main` POM](https://github.com/eclipse-pass/main).

Here are the most significant technologies used in DS:

* [Spring Boot](https://spring.io/projects/spring-boot) is used for functionality such as listening for JMS messages, configuration, “wiring-up” of DS components via dependency injection, and tests.
* There are unit and integration tests in DS. Tests are executed using [JUnit](https://junit.org/junit5/) and Spring Boot Test. [TestContainers](https://testcontainers.com/) are used for integration tests with pass-core.
* [Docker](https://www.docker.com/) is used for building a DS docker image that is used for deployment.
