🤔 Situation

It's difficult to read to and not_to. This makes human mistakes.

scenario 'Each panel should be isolated open/close ' do visit hoge_path(hoge_params) within('div.section-fugas') do expect(find('div.section-fuga:nth-child(1)')).to have_selector('div.section-fuga-body') expect(find('div.section-fuga:nth-child(2)')).to have_selector('div.section-fuga-body') expect(find('div.section-fuga:nth-child(3)')).not_to have_selector('div.section-fuga-body') expect(find('div.section-fuga:nth-child(4)')).not_to have_selector('div.section-fuga-body') find('div.section-fuga:nth-child(1)').find('a.section-fuga-a').click expect(find('div.section-fuga:nth-child(1)')).not_to have_selector('div.section-fuga-body') expect(find('div.section-fuga:nth-child(2)')).to have_selector('div.section-fuga-body') expect(find('div.section-fuga:nth-child(3)')).not_to have_selector('div.section-fuga-body') expect(find('div.section-fuga:nth-child(4)')).not_to have_selector('div.section-fuga-body') end end

👍 Solution

PORO, we have the def.
Plus, we get more flexibility by send(method, args).
Then, we can concentrate to judge the true/false.

def visibility_test(visibility_bools) expect(find('div.section-fuga:nth-child(1)')).send(visibility_bools[0] ? :to : :not_to, have_selector('div.section-fuga-body')) expect(find('div.section-fuga:nth-child(2)')).send(visibility_bools[1] ? :to : :not_to, have_selector('div.section-fuga-body')) expect(find('div.section-fuga:nth-child(3)')).send(visibility_bools[2] ? :to : :not_to, have_selector('div.section-fuga-body')) expect(find('div.section-fuga:nth-child(4)')).send(visibility_bools[3] ? :to : :not_to, have_selector('div.section-fuga-body')) end scenario 'Each panel should be isolated open/close ' do visit hoge_path(hoge_params) within('div.section-fugas') do visibility_test([true,true,false,false]) find('div.section-fuga:nth-child(1)').find('a.section-fuga-a').click visibility_test([false,true,false,false]) end end
