Act, arrange, assert - better organisation of your tests

[jerryjohnjacob]

When writing a test, there are generally 3 parts - arrange, act, assert.

• Arrange refers to the setup necessary for the test happens - setting up objects, assigning values, etc.
• Act is the actual action - the main line that produces the effect the test is checking.
• Assert refers to the 'test' part, where you're checking the output of the action and the desired result.

Keep these sections separated by a space.

Let's have a look at one of the tests you've written. Right now, all the lines are not separated in any way. Here's how to space them apart according to the scheme I've mentioned above:

it 'returns a hash with name, age, place when called to_hash' do
  the_hash = user.to_hash

  expect(the_hash).to be_a(Hash)
  expect(the_hash).to eq({name: 'Some Name', age: '21', place: 'Some Place'})
end
