    :depth: 3


This article explains how to build the ONAP Policy Framework for development purposes and how to run stability/performance tests for a variety of components. To start, the developer should consult the latest ONAP Wiki to familiarize themselves with developer best practices and how-tos to setup their environment, see `https://wiki.onap.org/display/DW/Developer+Best+Practices`.


This article assumes that:

* You are using a *\*nix* operating system such as linux or macOS.
* You are using a directory called *git* off your home directory *(~/git)* for your git repositories
* Your local maven repository is in the location *~/.m2/repository*
* You have copied the settings.xml from oparent to *~/.m2/* directory
* You have added settings to access the ONAP Nexus to your M2 configuration, see `Maven Settings Example <https://wiki.onap.org/display/DW/Setting+Up+Your+Development+Environment>`_ (bottom of the linked page)

The procedure documented in this article has been verified to work on a MacBook laptop running macOS Mojave Version 10.14.6 and an Unbuntu 18.06 VM.

Cloning All The Policy Repositories
***********************************

Run a script such as the script below to clone the required modules from the `ONAP git repository <https://gerrit.onap.org/r/#/admin/projects/?filter=policy>`_. This script clones all the ONAP Policy Framework repositories.

ONAP Policy Framework has dependencies to the ONAP Parent *oparent* module, the ONAP ECOMP SDK *ecompsdkos* module, and the A&AI Schema module.


.. code-block:: bash
   :caption: Typical ONAP Policy Framework Clone Script
   :linenos:

    #!/usr/bin/env bash

    ## script name for output
    MOD_SCRIPT_NAME=`basename $0`

    ## the ONAP clone directory, defaults to "onap"
    clone_dir="onap"

    ## the ONAP repos to clone
    onap_repos="\
    policy/parent \
    policy/common \
    policy/models \
    policy/docker \
    policy/api \
    policy/pap \
    policy/apex-pdp \
    policy/drools-pdp \
    policy/drools-applications \
    policy/xacml-pdp \
    policy/distribution \
    policy/gui \
    policy/clamp "

    ##
    ## Help screen and exit condition (i.e. too few arguments)
    ##
    Help()
    {
        echo ""
        echo "$MOD_SCRIPT_NAME - clones all required ONAP git repositories"
        echo ""
        echo "       Usage:  $MOD_SCRIPT_NAME [-options]"
        echo ""
        echo "       Options"
        echo "         -d          - the ONAP clone directory, defaults to '.'"
        echo "         -h          - this help screen"
        echo ""
        exit 255;
    }

    ##
    ## read command line
    ##
    while [ $# -gt 0 ]
    do
        case $1 in
            #-d ONAP clone directory
            -d)
                shift
                if [ -z "$1" ]; then
                    echo "$MOD_SCRIPT_NAME: no clone directory"
                    exit 1
                fi
                clone_dir=$1
                shift
            ;;

            #-h prints help and exists
            -h)
                Help;exit 0;;

            *)    echo "$MOD_SCRIPT_NAME: undefined CLI option - $1"; exit 255;;
        esac
    done

    if [ -f "$clone_dir" ]; then
        echo "$MOD_SCRIPT_NAME: requested clone directory '$clone_dir' exists as file"
        exit 2
    fi
    if [ -d "$clone_dir" ]; then
        echo "$MOD_SCRIPT_NAME: requested clone directory '$clone_dir' exists as directory"
        exit 2
    fi

    mkdir $clone_dir
    if [ $? != 0 ]
    then
        echo cannot clone ONAP repositories, could not create directory '"'$clone_dir'"'
        exit 3
    fi

    for repo in $onap_repos
    do
        repoDir=`dirname "$repo"`
        repoName=`basename "$repo"`

        if [ ! -z $dirName ]
        then
            mkdir "$clone_dir/$repoDir"
            if [ $? != 0 ]
            then
                echo cannot clone ONAP repositories, could not create directory '"'$clone_dir/repoDir'"'
                exit 4
            fi
        fi

        git clone https://gerrit.onap.org/r/${repo} $clone_dir/$repo
    done

    echo ONAP has been cloned into '"'$clone_dir'"'


Execution of the script above results in the following directory hierarchy in your *~/git* directory:

    *  ~/git/onap
    *  ~/git/onap/policy
    *  ~/git/onap/policy/parent
    *  ~/git/onap/policy/common
    *  ~/git/onap/policy/models
    *  ~/git/onap/policy/api
    *  ~/git/onap/policy/pap
    *  ~/git/onap/policy/gui
    *  ~/git/onap/policy/docker
    *  ~/git/onap/policy/drools-applications
    *  ~/git/onap/policy/drools-pdp
    *  ~/git/onap/policy/clamp
    *  ~/git/onap/policy/apex-pdp
    *  ~/git/onap/policy/xacml-pdp
    *  ~/git/onap/policy/distribution


Building ONAP Policy Framework Components
*****************************************

**Step 1:** Optionally, for a completely clean build, remove the ONAP built modules from your local repository.

    .. code-block:: bash

        rm -fr ~/.m2/repository/org/onap


**Step 2:**  A pom such as the one below can be used to build the ONAP Policy Framework modules. Create the *pom.xml* file in the directory *~/git/onap/policy*.

.. code-block:: xml
   :caption: Typical pom.xml to build the ONAP Policy Framework
   :linenos:

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <module>gui</module>
            <module>clamp</module>
        </modules>
    </project>

**Policy Architecture/API Transition**

In Dublin, a new Policy Architecture was introduced. The legacy architecture runs in parallel with the new architecture. It will be deprecated after Frankfurt release.
If the developer is only interested in working with the new architecture components, the engine sub-module can be ommitted.


**Step 3:** You can now build the Policy framework.

Java artifacts only:

    .. code-block:: bash

       cd ~/git/onap
       mvn clean install

With docker images:

    .. code-block:: bash

       cd ~/git/onap
       mvn clean install -P docker

Developing and Debugging each Policy Component
**********************************************

Running a MariaDb Instance
++++++++++++++++++++++++++

The Policy Framework requires a MariaDb instance running. The easiest way to do this is to run a docker image locally.

One example on how to do this is to use the scripts used by the policy/api S3P tests.

`Simulator Setup Script Example <https://gerrit.onap.org/r/gitweb?p=policy/api.git;a=tree;f=testsuites/stability/src/main/resources/simulatorsetup;h=9038413f67cff2e2a79d6345f198f96ee0c57de1;hb=refs/heads/master>`_

    .. code-block:: bash

       cd ~/git/onap/api/testsuites/stability/src/main/resources/simulatorsetup
       ./setup_components.sh

Another example on how to run the MariaDb is using the docker compose file used by the Policy API CSITs:

`Example Compose Script to run MariaDB <https://gerrit.onap.org/r/gitweb?p=integration/csit.git;a=blob;f=scripts/policy/docker-compose-api.yml;h=e32190f1e6cb6d9b64ddf53a2db2c746723a0c6a;hb=refs/heads/master>`_

Running the API component standalone
+++++++++++++++++++++++++++++++++++++

Assuming you have successfully built the codebase using the instructions above. The only requirement for the API component to run is a
running MariaDb database instance. The easiest way to do this is to run the docker image, please see the mariadb documentation for the latest
information on doing so. Once the mariadb is up and running, a configuration file must be provided to the api in order for it to know how to
connect to the mariadb. You can locate the default configuration file in the packaging of the api component:

`Default API Configuration <https://gerrit.onap.org/r/gitweb?p=policy/api.git;a=blob;f=packages/policy-api-tarball/src/main/resources/etc/defaultConfig.json;h=042fb9d54c79ce4dad517e2564636632a8ecc550;hb=refs/heads/master>`_

You will want to change the fields pertaining to "host", "port" and "databaseUrl" to your local environment settings.

Running the API component using Docker Compose
++++++++++++++++++++++++++++++++++++++++++++++

An example of running the api using a docker compose script is located in the Policy Integration CSIT test repository.

`Policy CSIT API Docker Compose <https://gerrit.onap.org/r/gitweb?p=integration/csit.git;a=blob;f=scripts/policy/docker-compose-api.yml;h=e32190f1e6cb6d9b64ddf53a2db2c746723a0c6a;hb=refs/heads/master>`_

Generating Swagger Documentation
********************************
The `Policy Parent Integration POM <https://github.com/onap/policy-parent/blob/master/integration/pom.xml>`_ contains a *generateSwaggerDocs* profile. This
profile can be activated on any module that has a Swagger endopint. When active, this profile creates a tarball in Nexus with the name
*<project-artifactId>-swagger-docs.tar.gz*. The tarball contains the fillowing files:

.. code-block:: bash

    swagger/swagger.html
    swagger/swagger.json
    swagger/swagger.pdf

The profile is activated when:

1. The following property is defined at the top of the *pom.xml* file for a module

    .. code-block:: bash

        <!--  This property triggers generation of the Swagger documents -->
        <swagger.generation.phase>post-integration-test</swagger.generation.phase>

    See the `CLAMP runtime POM <https://github.com/onap/policy-clamp/blob/master/runtime/pom.xml>`_ for an example of the usage of this property.

2. Unit tests are being executed in the build, in other wirds when the *skipTests* flag is *false*.

You **must** create a unit test in your module that generates the following file:

.. code-block:: bash

    src/test/resources/swagger/swagger.json

Typically, you do this by starting your REST endpoint in a unit test, issuing a REST call to get the Swagger API documentation. The test case below is an example
of such a test case.

.. code-block:: java

   @Test
   public void testSwaggerJson() throws Exception {
       ResponseEntity<String> httpsEntity = getRestTemplate()
               .getForEntity("https://localhost:" + this.httpsPort + "/restservices/clds/api-doc", String.class);
       assertThat(httpsEntity.getStatusCode()).isEqualTo(HttpStatus.OK);
       assertThat(httpsEntity.getBody()).contains("swagger");
       FileUtils.writeStringToFile(new File("target/swagger/swagger.json"), httpsEntity.getBody(),
               Charset.defaultCharset());
   }

See `this unit test case <https://github.com/onap/policy-clamp/blob/master/runtime/src/test/java/org/onap/policy/clamp/clds/it/HttpsItCase.java>`_
for the full example.

Running the DMaaP Simulator during Development
**********************************************
It is sometimes convenient to run the DMaaP simulator during development. You can run it from the command line using Maven or from within your IDE.

Running on the Command Line
+++++++++++++++++++++++++++
1. Check out the policy models repository
2. Go to the *models-sim/policy-models-simulators* subdirectory in the policy-models repo
3. Run the following Maven command:

   .. code-block:: bash

      mvn exec:java  -Dexec.mainClass=org.onap.policy.models.simulators.Main -Dexec.args="src/test/resources/simParameters.json"

Running in Eclipse
++++++++++++++++++
1. Check out the policy models repository
2. Go to the *models-sim/policy-models-simulators* module in the policy-models repo
3. Specify a run configuration using the class *org.onap.policy.models.simulators.Main* as the main class
4. Specify an argument of *src/test/resources/simParameters.json* to the run configuration
5. Run the configuration

Specifying a local configuration file
+++++++++++++++++++++++++++++++++++++

You may specify a local configuration file instead of *src/test/resources/simParameters.json* on the command line or as an arument in the run configuration in eclipse:

.. code-block:: json

   {
     "dmaapProvider": {
       "name": "DMaaP simulator",
       "topicSweepSec": 900
     },
     "restServers": [
       {
         "name": "DMaaP simulator",
         "providerClass": "org.onap.policy.models.sim.dmaap.rest.DmaapSimRestControllerV1",
         "host": "localhost",
         "port": 3904,
         "https": false
       }
     ]
   }
