如何使用 Jasmine 的 toEqual(jasmine.objectContaining) 方法来比较数组？

Question

Basically I wanna check corresponding elements of the arrays I partially equal.

Is there anything better than foreach loop with a nested toEqual(jasmine.objectContaining) ?

Answer 1

With angularjs and Jasmine 3.3.1, I have been successful with this kind of structure:

it('updates an prop on every object in an array', () => {
  const result = service.methodThatUpdates([{ prop: 'orig' }, { prop: 'orig' }]);
  expect(result).toEqual([
    jasmine.objectContaining({ prop: 'changed' }),
    jasmine.objectContaining({ prop: 'changed' })
  ]);
});

It is simpler than many toEqual calls.
