[RSpec] shared_context

simple code sample

subject { word }

shared_context 'hoge' do
  let(:word) { 'hoge' }
end
shared_context 'fuga' do
  let(:word) { 'fuga' }
end

context 'hoge' do
  include_context 'hoge'
  it { is_expected.to eq 'hoge' }
end

merit

Assume that you have like this many contexts, and the let() is not short.

In this way, we can concentlate to see what we test, instead to read a lot of code.

shared_context 'people_happy' do
  # looong!
end

context 'dog' do
  let(:animal) {creat(:dog)}
  context 'people_happy' do
    include_context 'people_happy'
    # test
  end
end
context 'cat' do
  let(:animal) {creat(:cat)}
  context 'people_happy' do
    include_context 'people_happy'
    # test
  end
end
context 'horse' do
  let(:animal) {creat(:hourse)}
  context 'people_happy' do
    include_context 'people_happy'
    # test
  end
end
