Response Query

The res object that is available inside the vars, assertions and scripting contexts can be queried for data by invoking it like below.

Think of it as lodash.get() on steroids

javascript
res('order.total')

Examples

javascript
const data = {
  customer: {
    address: {
      city: "bangalore"
    },
    orders: [
      {
        id: "order-1",
        items: [
          { id: 1, amount: 10 },
          { id: 2, amount: 20 },
        ]
      },
      {
        id: "order-2",
        items: [
          { id: 3, amount: 30, },
          { id: 4, amount: 40 }
        ]
      }
    ]
  },
