The test below is passing. However there'd be no coverage. Apparently the promise does not resolve which is always in pending state. What I did is to break the Promise chain and put the pieces in two different functions to make it look like BDD style.

How do I get that covering my code. Any help would be much appreciated?

NodeJs 14.17.3 ts-jest 27.4.1 Jest 27.4.1.

const request = require('supertest')

let res:Promise<any>
let a:string
let b:string

it('should return ....', async () => {
   given('', '')
   when()
   then()
}

async function given(a:string, b:string) {
   // assignments go here 
}

async function when() {
   cons runPro = async (): Promise<any> => {
       return new Promise((resolve, reject) => {
             request(baseurl).get('theurl').then((value:any) => {
                  resolve(value.body)
             }).catch(error => {
                  reject(err)
              })
         }).catch(error => {
            // 
         }
     }
      res = runPro()
}

async function then() {
     res.then(value => {
        expect(value).toEqual("")
    }
}
