This project was written from scratch using jus npm init command to showcase how to start with jest testing framework in combination with Kentico Cloud Delivery SDK.

1. Initialize the npm application

   1. Create a project folder

   mkdir kc-jest
   cd kc-jest

   1. Initialize the npm package

   npm init -y

   This will generate package.json file (more info).

2. Add .gitignore file to avoid spamming repository by node_modules content

3. Install all required dependencies

   npm install --save-dev rxjs kentico-cloud-delivery jest

   • rxjs is a peer dependency for kentico-cloud-delivery
   • jest is a testing framework

   Development dependencies are listed in [package.json] an installed in node_,modules folder.

   {
     ...
     "devDependencies": {
       "jest": "^24.7.1",
       "kentico-cloud-delivery": "^5.7.2",
       "rxjs": "^6.4.0"
     }
     ...
   }
   

4. Write the (end-to-end) test (delivery.test.js)

   const { DeliveryClient } = require('kentico-cloud-delivery');
   
   describe('Delivery sdk', () => {
     it("load articles", async () => {
       const client = new DeliveryClient({
          projectId: "975bf280-fd91-488c-994c-2f04416e5ee3"
          });
   
       const result = await client.items()
         .type("article")
         .getPromise();
   
       expect(result).toHaveProperty('items');
       expect(result.items).toHaveLength(6);
       result.items.forEach(item => console.log(item.elements.title.value)); // Just to see the titles in log
       // expect(result).toMatchSnapshot(); // Just a snapshot sample (https://jestjs.io/docs/en/snapshot-testing)
     })
   })

5. Add test script to the package.json,

   {
     ...
     "scripts": {
         "test": "jest"
     }
   }
   

6. Run the tests

npm run test

Hurray! Kentico Cloud ❤️ Jest!
