Add the above pom.xml to your CBA and change artifactId to your-cba-name.

The pom references a parent which defines all test dependencies. The parent also includes a profile (-Pdeploy-cba) which will enrich and publish the CBA to a running CDS instance.

The deploy-cba profile can be configured by setting properties described in the example pom.

mvn clean test

# This will build /target/your-cba-name-1.0.0-SNAPSHOT-cba.zip
mvn clean install

# This will build /target/your-cba-name-1.0.0-SNAPSHOT-cba.zip 
# Enrich CBA and add /target/your-cba-name-1.0.0-SNAPSHOT-enriched-cba.zip
# Publish CBA to CDS 
mvn clean install -Pdeploy-cba

Add Unit tests

Kotlin unit tests should be added under /Tests/kotlin as show above. Test files must contain "Test" in the filename, for example ScriptTest.kt or TestScript.kt

Example project:

Libraries:

https://junit.org/junit4/

https://mockk.io/

Debugging

After the pom is added, the CBA can be used in IntelliJ as a maven project.

Create a new empty project

Give it a name

Click the + symbol and select import module

Select the pom.xml in your CBA directory

You should now be able to write, run and debug unit tests

CDS Runtime debuging

Open File → Project Structure

Click the + symbol and select Import Module

Select pom.xml in the CDS root directory

You should now have both your CBA and CDS as modules in the project

Make sure your cds run configuration is setup properly and then start CDS in debug mode

Right-click your cba package and select Open In Terminal

Make sure your cds properties are correct in your CBA pom.xml, then run the below command in the terminal

mvn clean install -Pdeploy-cba

Maven will enrich and deploy your CBA to CDS

You should now be able to place breakpoints in your script

Send your request to CDS and start debugging
