Jose Lausuch, Ericsson I have developed and integrated a new feature but… how do I write test cases and where do I put them? How do I start? These are common questions asked by developers bringing new features that need to be tested and verified in our CI pipeline.

2. Hands-On Testing: How to
Integrate Tests in OPNFV

4. Do not worry
we make it easy for you

5. 1) Check the documentation
We have plenty of documents and guides that can help you

6. Documentation (e.g Functest)
• Config guide
• User guide
• Developer guide
• http://testresults.opnfv.org/functest/framework/
• API Docs
• https://wiki.opnfv.org/display/functest

7. 2) Get familiar with the environment
Deploy OPNFV with your desired features installed
Follow the instructions to set up the test framework
Run tests

8. 3) Write a dummy test case
Before testing your feature, make sure you can run
a simple “Hello World” with the test framework.
The framework should return “test successful”

9. 4) Add the content of the test
Once you understand how to integrate a test in the
framework, you can start writing the code that exercises
your feature
Make use of framework libraries and helper functions

10. 5) Declare the test case in the Test DB
There is a Database to store community results from CI runs
It is also used to store some information, such as:
• Test cases per project
• CI PODs
• Scenarios
Easy to do this using the Rest API
https://wiki.opnfv.org/pages/viewpage.action?pageId=6825128

11. {
"project_name": “myProject",
"run": "",
"name": "myTest",
"ci_loop": "daily",
"tags": "",
"blocking": "false",
"domains": "networking",
"dependencies": "",
"version": ">Euphrates",
"criteria": "",
"tier": "features",
"trust": "silver",
"catalog_description": "Hello world test case",
"description": "Hello world test case blah blah "
}

12. 6) Push your code
You probably want to keep the code of your test in your repo
BUT
You will need to enable some things in the test framework

13. Example: Doctor test case in Functest
-
case_name: doctor-notification
project_name: doctor
criteria: 100
blocking: false
description: >-
Test suite from Doctor project.
dependencies:
installer: '(apex)|(fuel)'
scenario: '^((?!fdio).)*$'
run:
module: 'functest.core.feature'
class: 'BashFeature'
args:
cmd: 'cd /home/opnfv/repos/doctor/tests && ./run.sh'
testcases.yamlDockerfile
THAT’S IT!

14. 7) Finally
Once the code is merged in your
repository and in the test framework
 Check CI
