Sample Properties can be used to help you configure the adapter in the Itential Automation Platform. You will need to update connectivity information such as the host, port, protocol and credentials.

Generic Adapter Information

Itential Product and opensource adapters utilize SemVer for versioning. The current version of the adapter can be found in the package.json file or viewed in the Platform GUI on the System page. All Itential opensource adapters can be found in the Itential OpenSource Repository.

Any release prior to 1.0.0 is a pre-release. Initial builds of adapters are generally set up as pre-releases as there is often work that needs to be done to configure the adapter and make sure the authentication process to Puppet works appropriately.

Release notes can be viewed in CHANGELOG.md.

Itential Product adapters are built for particular versions of Platform and packaged with the versions they work with.

Itential opensource adapter as well as custom adapters built with the Itential Adapter Builder work acoss many releases of Platform. As a result, it is not often necessary to modify an adapter when upgrading Platform. If Platform has changes that impact the pronghorn.json, like adding a new required section, this will most likely require changes to all adapters when upgrading Platform.

Many of the scripts that come with all adapters built using the Itential Adapter Builder do have some dependencies on Platform or the Platform database schema and so it is possible these scripts could stop working in different versions of Platform. If you notify Itential of any issues, the Adapter Team will attempt to fix the scripts for newer releases of Platform.

These instructions will help you get a copy of the project on your local machine for development and testing. Reading this section is also helpful for deployments as it provides you with pertinent information on prerequisites and properties.

#### Helpful Background Information

There is Adapter documentation available on the Itential Documentation Site. This documentation includes information and examples that are helpful for:

#### Prerequisites

The following is a list of required packages for installation on the system the adapter will run on:

`text
Node.js
npm
Git
`

The following list of packages are required for Itential opensource adapters or custom adapters that have been built utilizing the Itential Adapter Builder. You can install these packages by running npm install inside the adapter directory.

`text
chai
eslint
eslint-config-airbnb-base
eslint-plugin-import
eslint-plugin-json
testdouble
`

#### How to Install

1a. If you are working on Itential Platform 2023.2 or earlier versions, set up the name space location in your Itential Platform node_modules.

`bash
cd /opt/pronghorn/current/node_modules (* could be in a different place)
if the @itentialopensource directory does not exist, create it:
mkdir @itentialopensource
cd @itentialopensource
`

1b. If you are working on Platform 6, you need to install the adapter in the services directory.

`bash
cd /opt/itential/platform/services (* you may have configured it to be in a different place)
`

2. Clone/unzip/tar the adapter into your Platform environment.

`bash
git clone git@gitlab.com:@itentialopensource/adapters/adapter-puppet
or
unzip adapter-puppet.zip
or
tar -xvf adapter-puppet.tar
`

3. install the adapter dependencies.

`bash
cd adapter-puppet
npm install
npm run lint:errors
npm run test
`

4. Restart Platform

`bash
systemctl restart pronghorn
`

5. Create an adapter service instance configuration in Platform Admin Essentials GUI

6. Copy the properties from the sampleProperties.json and paste them into the service instance configuration in the inner/second properties field.

7. Change the adapter service instance configuration (host, port, credentials, etc) in Platform Admin Essentials GUI

#### Testing

Mocha is generally used to test all Itential Opensource Adapters. There are unit tests as well as integration tests performed. Integration tests can generally be run as standalone using mock data and running the adapter in stub mode, or as integrated. When running integrated, every effort is made to prevent environmental failures, however there is still a possibility.

##### Unit Testing

Unit Testing includes testing basic adapter functionality as well as error conditions that are triggered in the adapter prior to any integration. There are two ways to run unit tests. The prefered method is to use the testRunner script; however, both methods are provided here.

`bash
node utils/testRunner --unit

npm run test:unit
npm run test:baseunit
`

To add new unit tests, edit the test/unit/adapterTestUnit.js file. The tests that are already in this file should provide guidance for adding additional tests.

##### Integration Testing - Standalone

Standalone Integration Testing requires mock data to be provided with the entities. If this data is not provided, standalone integration testing will fail. When the adapter is set to run in stub mode (setting the stub property to true), the adapter will run through its code up to the point of making the request. It will then retrieve the mock data and return that as if it had received that data as the response from Puppet. It will then translate the data so that the adapter can return the expected response to the rest of the Itential software. Standalone is the default integration test.

Similar to unit testing, there are two ways to run integration tests. Using the testRunner script is better because it prevents you from having to edit the test script; it will also resets information after testing is complete so that credentials are not saved in the file.

`bash
node utils/testRunner
answer no at the first prompt

npm run test:integration
`

To add new integration tests, edit the test/integration/adapterTestIntegration.js file. The tests that are already in this file should provide guidance for adding additional tests.

##### Integration Testing

Integration Testing requires connectivity to Puppet. By using the testRunner script it prevents you from having to edit the integration test. It also resets the integration test after the test is complete so that credentials are not saved in the file.

> Note: These tests have been written as a best effort to make them work in most environments. However, the Adapter Builder often does not have the necessary information that is required to set up valid integration tests. For example, the order of the requests can be very important and data is often required for creates and updates. Hence, integration tests may have to be enhanced before they will work (integrate) with Puppet. Even after tests have been set up properly, it is possible there are environmental constraints that could result in test failures. Some examples of possible environmental issues are customizations that have been made within Puppet which change order dependencies or required data.

`bash
node utils/testRunner
answer yes at the first prompt
answer all other questions on connectivity and credentials
`

Test should also be written to clean up after themselves. However, it is important to understand that in some cases this may not be possible. In addition, whenever exceptions occur, test execution may be stopped, which will prevent cleanup actions from running. It is recommended that tests be utilized in dev and test labs only.

> Reminder: Do not check in code with actual credentials to systems.

#### Node Scripts

There are several node scripts that now accompany the adapter. These scripts are provided to make several activities easier. Many of these scripts can have issues with different versions of Platform as they have dependencies on Platform and Mongo. If you have issues with the scripts please report them to the Itential Adapter Team. Each of these scripts are described below.
