#Navigating
    visit('/projects')
    visit(post_comments_path(post))

#Clicking links and buttons
    click_link('id-of-link')
    click_link('Link Text')
    click_button('Save')
    click('Link Text') # Click either a link or a button
    click('Button Value')

#Interacting with forms=
    fill_in('First Name', :with => 'John')
    fill_in('Password', :with => 'Seekrit')
    fill_in('Description', :with => 'Really Long Text…')
    choose('A Radio Button')
    check('A Checkbox')
    uncheck('A Checkbox')
    attach_file('Image', '/path/to/image.jpg')

#scoping
    within("//li[@id='employee']") do
      fill_in 'Name', :with => 'Jimmy'
    end

#Querying
    page.has_xpath?('//table/tr')
    page.has_css?('table tr.foo')
    page.has_content?('foo')
    page.should have_xpath('//table/tr')
    page.should have_css('table tr.foo')
    page.should have_content('foo')
    page.should have_no_content('foo')
    find_field('First Name').value
    find_link('Hello').visible?
    find_button('Send').click
    find('//table/tr').click
    locate("//*[@id='overlay'").find("//h1").click
    all('a').each { |a| a[:href] }

#Scripting
    result = page.evaluate_script('4 + 4');

#Debugging
    save_and_open_page

#Asynchronous JavaScript
    click_link('foo')
    click_link('bar')
    page.should have_content('baz')
    page.should_not have_xpath('//a')
    page.should have_no_xpath('//a')

#XPath and CSS
    within(:css, 'ul li') { ... }
    find(:css, 'ul li').text
    locate(:css, 'input#name').value
    Capybara.default_selector = :css
    within('ul li') { ... }
    find('ul li').text
    locate('input#name').value

##Comments to consider:

## 1
# 1 Correct method name is click_on, not click 
# 2 default_selector in Capybara 2 is :css so examples in section scoping should be updated.
# 3 Capybara 2.1 by default finds only visible elements so find_link('Hello').visible? doesn't really make sense
# 4 There's no such method as locate in Capybara
# 5 all('a').each { |a| a[:href] } is inefficient if page contains a lot of links and driver is quiet slow (like Selenium) as Capybara will make a query to driver for each invocation of #[]. Instead I advice to get array of elements' attributes using execute_script like it's shown here

## 2
#have_selector works when you use 'expect' syntax:
#expect(page).to have_selector 'foobar'

## 3
#within now works differently:
#within("li#employee") do
#    fill_in 'Name', :with => 'Jimmy'
#end
#
#within(:xpath, "//li[@id='employee']") do
#   fill_in 'Name', :with => 'Jimmy'
#end

# Hi, it is very useful. Just for "add value", in multiple select exists unselect(Option, from: select_box)
