TM Forum Open API Conformance Testing and Validation Instructions Page

...


The following guidelines will take you through the various steps needed to run self-testing for your

...

APIs to achieve conformance certification.

Self-Certification is based on the TM Forum Open API conformance profiles, it is the process by which an implementation is confirmed to support the standard definition of a TM Forum Open API.

...

...

  The TM Forum provides a set of scripts useful to self-certify your implementation of TM Forum Open API specifications. You will need to install and run the applicable API CTK.

...

As of April 2023, there are 59 CTKs available for conformance testing and the list

...

continues to grow steadily

...

...

...

Currently available conformance profiles and CTKs can be found in our TM Forum Open API portal. 

...




The following instructions describe how to install

...

and run an Open API CTK

...

:  

...

Newman (needed for CTK test execution), this is the command line version of 'Postman'; installation instructions available at: https://www.getpostman.com/docs/newman_intro

...

Node.js offers a server-side environment, which allows the use of JavaScript language to generate web pages. Basically, it replaces server languages such as PHP, Java EE, etc. Once Node.js is installed, Newman is just a command away:

npm install -g newman

This installs Newman from npm globally on your system allowing you to run it from anywhere.

npm makes it easy for JavaScript developers to share and reuse code, and it makes it easy to update the code that you're sharing. (You can download npm from here).

(This example is covering Product Offering Qualification for the 18.0 Release, but the steps to run a CTK are similar, unless stated on the readme.md that comes with the CTK).

1.

Installing and Running Conformance Test Kit
The CTK is dependent on the installation of node.js and npm to work.
Node.js and NPM can be downloaded and installed from

...

Once Node.js and

...

npm are installed

...

1  Import CTK from TM Forum

  • Download and unzip postman collection file for selected API from the corresponding page (see CTK links provided above)
  • Store downloaded file into the folder in your system where Newman runs

2  Configure environment

  • Download environment file (TMFENV) from the following link: TMFENV File
  • Modify environment file to refer to the endpoint where the implementation to be certified is running (see step 3 below)
  • Store modified file into the folder in your system where Newman runs

3  You need to create your testing environment. The environment is a text file without extension written in JSON. It has the following format:

You can use this as a template. Create a file with this format, replace the values for the name, the host and your API addresses and put it in the same folder as the postman collections.

4  Now create the right script or batch file for your platform (either Windows or Linux/Mac), put it in the same folder and run script execution command. For example, you can use a batch file (runtest.bat) which would look like the following example:
 

set http_proxy=http://proxyinternet.tesa:8080
newman -c DSTestedAPITestCollection.postman_collection -e TMFENV -H DSTestedAPICTKResult.html -o DSTestedAPICTKResult.json
pause >nul

5  A folder name results will be created and filled with the output of the tests. You should see something like the following:

If they are no failures, then you have passed the CTK and your API is conformant with all the Mandatory features.

The results of the CTK are in the DSTestedAPICTKResult.html and DSTestedAPICTKResult.json files and should look like the following (example with Customer Management API):

All the information related to the execution of the CTK will be contained in the DSTestedAPICTKResult.json file.

 The following is a complete example for the Trouble Ticket API:

download and unzip the TMF679-ProductOfferingQualification ZIP file within your test directory.

You should see the following files between many others :

Windows-RUNCTK.ps1

Linux-RUNCTK.sh

2.

For Windows:
Right click Windows-RUNCTK.ps1 and select run with PowerShell, press Y and Enter, wait for the dependencies to be installed go to Step 2.

For Linux and Mac:
You need to give executable permission for the Linux-RUNCTK.sh file, you can do that by opening a terminal and typing:

bash Linux-RUNCTK.sh

Wait for NPM to install the dependencies and go to step 2.

3.

Enter the URL for the base of your API, for example, if you can get a resource on:

https://tm-forum-open-api-reference-implementation.mybluemix.net/tmf-api/productOfferingQualificationManagement/v1/productOfferingQualification

You should input:
https://tm-forum-open-api-reference-implementation.mybluemix.net/tmf-api/productOfferingQualificationManagement/v1

The script will now run for a few minutes and when it ends, you will have a resultsHTML.html file inside the folder, this is the file you need to forward to TMForum to get your certification if your API passed every test, the file should look like this:
