Setting up your development environment
Clamp is built using maven and is mostly composed of java code. Please follow the instructions under the Setting your development environment page to prepare your machine for developing clamp.
Cloning CLAMP code
CLAMP code is located in a single git repository named clamp
...
Please make sure to review the ONAP Development Procedures and Policies to understand how to interact with the gerrit/git repositories.
Project structure
CLAMP is composed of a main pom.xml and several sub modules.
...
is structured in only one maven module, there is no sub-modules. It's composed of a back-end written in java, and a Designer UI front-end written in HTML/javascript (with angularJS).
The back-end code is stored in the standard java locations "/src/main/java", "src/main/resources". And all the back-end tests are located in "src/test/java", "src/test/resources".
The front-end code is stored in a sub folder of the back-end code in "src/main/resources/META-INF/resources".
Unit test
The unit tests are composed of 2 different types:
- The standard unit tests, testing obviously the class and methods
- The Spring integration tests that really starts Clamp (using @SpringBootTest) and that can make use of everything in the code, like the database, the http connection, etc ...
Those tests must have a specific filename pattern: **ItCase.java
The code coverage is done by Jacoco and the reports are configured to provide unit tests and integration coverage.

Building CLAMP
To build CLAMP you need to use maven with the goal "clean install". By default it executes the standard unit tests and the Spring integration tests but does not build the docker images.
You can disable the integration tests by executing: "mvn clean install -DskipITs=true"
There are one profile to build the docker image named "docker", to build the docker image: "mvn clean install -P docker"
Testing CLAMP
We created CSIT (Continuous System and Integration Testing) tests for clamp as requested for each ONAP component. This use Robot Framework. See this wiki page for more information: Creating a CSIT Test
