#rails

basic

๐Ÿ‘ find by attributes (find by name) 



find('input[type="checkbox"]').click
find('a[href="/dashboard"]').click
find('[name="user_form[age]"]')
Enter fullscreen mode Exit fullscreen mode

๐Ÿ‘ find by name 



find('a', name: 'click here').click
Enter fullscreen mode Exit fullscreen mode

๐Ÿ‘ find by element and class 



# <div class='my-class'>hello</div>
find('div.my-class').text

# <div id='book-body'>
#    <div class='book-contents vertical'>ใซใปใ‚“ใ”</div>
# </div>
find('#book-body > book-contents.vertical').text
Enter fullscreen mode Exit fullscreen mode

๐Ÿ‘ find invisible element 



find('p.message', visible: false).text
Enter fullscreen mode Exit fullscreen mode

advanced

๐Ÿ‘ find the parent of the node 



# just one parent node
find('#target_node').find(:xpath, '..')

# recursively parent
el.find(:xpath, '../../../dt')
el.find(:xpath, 'ancestor::dl')
Enter fullscreen mode Exit fullscreen mode

๐Ÿ“š Recursively go up or down | XPath tutorial

๐Ÿค” find from several same selector

๐Ÿ‘ปBad code

You'll see Ambiguous match error if you use just a find method.



<div class='base'>
  <span class='greeting'>hello</span>
  <span class='greeting'>goodbye</span>

  <a href="#">link_1</a>
  <a href="#">link_2</a>
</div>
Enter fullscreen mode Exit fullscreen mode 


find('span.greeting')
#=> Capybara::Ambiguous: Ambiguous match, found 2 elements matching visible css ('span.greeting')
Enter fullscreen mode Exit fullscreen mode

๐Ÿ‘good code 



first('div.hello')
all('div.hello')
Enter fullscreen mode Exit fullscreen mode
  • Cons
    • Easy
  • Pros
    • they don't wait for the selector is rendered.
    • you have to maintain if selector order is modified in the future.

๐Ÿ“š Stack Overflow

๐Ÿฆ„ good code 



find('div.base > span:nth-child(1)').text #=> hello
find('div.base > span:nth-child(2)').text #=> goodbye

find('div.base > span:nth-of-type(1)').text #=> hello
find('div.base > span:nth-of-type(2)').text #=> goodbye

find_link('link_1', match: :first).cilck
Enter fullscreen mode Exit fullscreen mode

nth-of-type is better.

๐Ÿ“š nth-child

Hey, I have been googling stuff for last hour trying to find a solution to a problem I was having and this is the page that gave me the answer, thank you so much. Btw, solution to my problem was essentially:

# Find the first input within an element of class class_name
find(.class_name > input)
Enter fullscreen mode Exit fullscreen mode

Thank you

Nice concise tips! I think you got "pros" and "cons" backwards here:

  • Cons
    • Easy
  • Pros
    • they don't wait for the selector is rendered.
    • you have to maintain if selector order is modified in the future.

I recreated this note because the previous one is somewhat crashed. When I press the 'EDIT' button, it shows previous (maybe, 3 or 4 previous) version of one.
