The Jakarta Data project, a part of the Jakarta EE ecosystem, aims to simplify the development of data-centric applications by providing a standard API for accessing and manipulating data from various sources. As with any standard, the Jakarta Data project requires a Technology Compatibility Kit (TCK) to ensure compliance and interoperability among different implementations. This document presents a proposal for the Jakarta Data TCK, focusing on delegating Dependency Injection (DI) and annotations to the vendors.

Instructions

1 Include the dependency:

<dependency>
    <groupId>br.org.soujava.jakarta</groupId>
    <artifactId>tck</artifactId>
    <version>${project.version}</version>
    <scope>test</scope>
</dependency>

2 Implement both: the entity and the repository

This moment, be free to use either the entity’s implementation annotation and the repository supplier.

//vendor annotations
public class BookAnyVendor implements Book {

}
@Repository
public interface Library extends CrudRepository<BookAnyVendor, String> {
}

3 Implement the supplier

On this step implement the classes to create the entity and the DI engine.

public class BookVendorSupplier implements BookSupplier {
    //implementation
}

public class DISupplier implements ContainerSupplier {
      //implementation
}

4 register SPI

Create the SPI to those suppliers.

5 append tests on the maven project

Include these suppliers at the maven test:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${maven.surefire.plugin.version}</version>
    <configuration>
        <dependenciesToScan>
            <dependency>br.org.soujava.jakarta:tck</dependency>
        </dependenciesToScan>
    </configuration>
</plugin>

6 run the tests

mvn clean test
