RSpec Expect Hash to include an Array of key value pairs

Question

Still learning Rspec as a whole, so thanks for patience.

Return value is this:

{ supermodel: { 'id': 1, 'name': 'J', 'model_attributes': [ {attr1: 'T', attrA: 1}, {attr2: 'F', attrB: 2}, {attr3: 'T', attrC: 3} ], } }

Trying to get an expectation that says that a hash key named 'model_attributes' contains a value of an array that includes the following key value pairs - {attr2:F, attrB: 2} and {attr3: T, attrC: 3}.

Any insight would be welcome.

your Result of method is this.. is invalid Ruby object, double check it ;) — Andrey Deineko

True @AndreyDeineko reformatted the assertion to be more ruby. Thanks! — JoaWa

@JoaWa i meant, that 'model_attributes': [ {attr1: T, attrA: 1}, {attr2: F, attrB: 2}, {attr3: T, attrC: 3} ] is not a valid object in Ruby. It looks almost like a hash, but it lacks braces and still would be invalid because of T, F - these will throw an Uninitialized constant T — Andrey Deineko

Sorry for the lack of clarity @AndreyDeineko. Provided the big picture return sample. Was aiming for brevity, but lacked in accuracy. Thanks for input. — JoaWa

describe 'Stuff' do let(:model_attributes) do [ {attr1: 'T', attrA: 1}, {attr2: 'F', attrB: 2}, {attr3: 'T', attrC: 3} ] end let(:result) do { supermodel: { 'id': 1, 'name': 'J', 'model_attributes': model_attributes } } end it 'has the correct model_attributes value' do expect(result.dig(:supermodel, :model_attributes)).to eq(model_attributes) end end

Try

describe 'ModelAttributes' do let(:model_attributes) { [{ attr1: 'T', attrA: 1 }, { attr2: 'F', attrB: 2 }, { attr3: 'T', attrC: 3 }] } it 'includes the required attributes' do expect(model_attributes).to include({ attr2:'F', attrB: 2 }, { attr3: 'T', attrC: 3 }) end end

In retrospect this is alot easier now. Simply traversing the hash and expecting the values was the easiest way. Refactoring ended me up in doing this:

supermodel[:model_attributes].each do |attr| expect(attr[:attrB])to be 2 end

Thanks for all the suggestions, led me down the right path.
