In this exercise, you will learn how to set up a Mock Server for Business Partner API of SAP S/4HANA Cloud for testing purposes.

1. Clone the Mock Server repository and checkout the branch mock-server in SAP Business Application Studio

   1. Open SAP Business Application Studio.

   2. Run the following commands in the terminal

      Code snippet

      Copy code

      cd ~/projects
      git clone https://github.com/SAP/cloud-s4-sdk-book.git
      cd cloud-s4-sdk-book
      git checkout mock-server

2. Copy the EDMX document of business partner into the business-partner folder

   1. Browse to the SAP API Business Hub in a separate tab, then login.

   3. Copy the API_BUSINESS_PARTNER.edmx file into the business-partner folder.

      

      Note

      Sometimes the XML file indentation and consequent color coding are lost during the upload, so the file content looks like a coutinuous senquence of (black) characters. Be aware this is not impacting the xml structure, so the file will be anyway good for the exercise execution.

3. Run the mock server on port 8081

   1. Edit the server.js and replace port 3000 with port 8081.

   2. Run the following commands in the Terminal, to install the dependencies and start the mock server

      Code snippet

      Copy code

      npm install
      npm run start

      Expand
      

4. Test the mock server by issuing a GET request to A_BusinessPartner entity

   2. Add the following content to the file

      Code snippet

      Copy code

      ### GET Business Partners
