Using JEST I want to test if an array of objects is a subset of another array.
I want to test the following:
const users = [{id: 1, name: 'Hugo'}, {id: 2, name: 'Francesco'}, {id: 3, name: 'Carlo'}];
const subset = [{id: 1, name: 'Hugo'}, {id: 2, name: 'Francesco'}];
expect(users).toContain(subset)
I’ve tried the following:
describe('test 1', () => {
it('test 1', () => {
expect(users).toEqual(
expect.arrayContaining([
expect.objectContaining(subset)
])
)
});
});
But this is not correct since objectContaining doesn’t accept array as param … it works only if subset is a single object.
