I want to check a pattern I'm using when converting the tests to typescript.

With the update some of the data being used needs to be actual repositories and no longer "loose data". eg:

 const discount = {
        rule: {
          type: "percentage",
          value: 10,
        },
      }
     
      res = totalsService.getAllocationItemDiscounts(discount, cart)

Now needs to be :

      const discount = discountRepositoryMock.create({
        rule: {
          type: DiscountRuleType.PERCENTAGE,
          value: 10,
        },
      })

      res = totalsService.getAllocationItemDiscounts(discount, cart)

Is the pattern I have in this PR correct - I'm putting the discountRepositoryMock in the src/repositories/__mocks__/discount.js file (obviously that needs to be changed to ts too) ?
