How to Perform Partial Object Matching in Jest

Goal

Checking if

{
  "id": 1,
  "name": "taro",
  "age": 10
}

contains

{
  "name": "taro",
  "age": 10
}

How to do it

Use expect.objectContaining!

const obj = {
  id: 1,
  name: "taro",
  age: 10,
};

expect(obj).toEqual(
  expect.objectContaining({
    name: "taro",
    age: 10,
  })
);
