Keptn NeoLoad Service

This service is designed to use NeoLoad for executing various Load testing tasks.

To trigger a NeoLoad test, the service has subscriptions to event channels. In more details, the current implementation of the service listens to CloudEvents from type:

• sh.keptn.events.deployment-finished: When receiving this event, the service executes a test for a deployed application. This event would be replace by the start test event

Secret for credentials

During the setup of NeoLaod, a secret is created that contains key-value pairs for the NeoLoad URL, NeoLoad apiKey:

• NL_WEB_HOST
• NL_API_HOST
• NL_UPLOAD_HOST
• NL_API_TOKEN
• NL_WEB_ZONEID

Install service

1. To install the service, you need to run :

• installer/defineNeoLoadWebCredentials.sh to configure the required parameters :
  1. NL_WEB_HOST : host of the web ui of NeoLoad web
  2. NL_API_HOST : host of the api of NeoLoad web
  3. NL_UPLOAD_HOST : host of upload api of NeoLoad Web
  4. NL_API_TOKEN: api token of your NeoLoad account
  5. NL_WEB_ZONEID : NeoLoad Web Zone id that would be used by Keptn

The NeoLoad Service requires to store the keptn.neoload.engine.yaml file in the ressources of keptn

1. Create your keptn.neoload.engine.yaml file describing the test and the infrastructure

steps:
- step:
    repository: https://yourreposistory/project.git
    branch: master
    teststrategy: performance
    project:
    - path: /tests/neoload/load_template/load_template.nlp
    - path: /tests/neoload/catalogue_neoload.yaml
    description: BasicCheck
    scenario: BasicCheck
    constant_variables:
    - name: server_host
      value: catalog-service.orders-project-dev.svc
    - name: server_port
      value: 8080
    infrastructure:
      local_LG:
      - name: lg1
      populations:
      - name: BasicCheck
        lgs:
        - name: lg1

Here is a template of a keptn.neoload.engine.yaml file The repository needs to have the url of your source control repo containing your NeoLoad tests. The property project will have the list of the relative path of your neoload project files. A NeoLoad project can be combined of a NeoLoad gui project ( nlp) , yaml files, or both.

constant_variables is the object allowing you to replace the value of constant variable defined in your project.

infrastructure is the object describing the Load testing infrastructure required for this test.

2. Once your keptn.neoload.engine.yaml file created , you will need to store in keptn by sending the following command :

   keptn add-resource --project=your-project --service=my-service --stage=your stage --resource=keptn.neoload.engine.yaml

   here is the ling to keptn's documentation.
