Make your Rails Capybara testing even faster and more accurate! Looking for hardcoded text strings is for the birds.
|
|
|
|
A lot of this assumes you're using a form builder to generate forms, like Formtastic. It's faster that way.
|
|
|
|
## Your Views
|
|
|
|
It's easier to find things in Capybara tests if you add extra `data` attributes to fields and such.
|
|
This gem does that for you if you link to and refer to things in a certain way. If you do, your
|
|
tests turn from text blob and CSS selector messes to nice, clean, simple references to objects
|
|
and attributes.
|
|
|
|
### Linking to things
|
|
|
|
Link to things using `link_to_model`, `link_to_model_action`, `link_to_collection`, and `link_to_route`.
|
|
Data attributes will be added that Capybara can then find later, and quickly:
|
|
|
|
``` haml
|
|
#menu
|
|
= link_to_route :root
|
|
= link_to_collection [ :admin, :users ]
|
|
= link_to_model current_user
|
|
= link_to_model_action current_user, :edit
|
|
```
|
|
|
|
``` ruby
|
|
# finding those things
|
|
|
|
within '#menu' do
|
|
find_semantic_link(:root)
|
|
find_semantic_link(:users)
|
|
find_object(@user)
|
|
find_action(:edit)
|
|
end
|
|
```
|
|
|
|
### Form fields
|
|
|
|
Don't worry about tying your field entry with text labels. It's much easier to look for attributes by name:
|
|
|
|
``` ruby
|
|
find_input(:first_name).set("first name")
|
|
find_input(:last_name).set("last name")
|
|
set_input(:gender, 'male')
|
|
find_submit.click
|
|
```
|
|
|
|
### Attributes
|
|
|
|
Write out attributes using `attributes_for`:
|
|
|
|
``` haml
|
|
#object
|
|
= attributes_for object do |f|
|
|
%h2= f.field(:name)
|
|
%h3= f.field(:description)
|
|
```
|
|
|
|
Then look for those fields using Capybara! Because you shouldn't care about the DOM, just that your
|
|
field is in there:
|
|
|
|
``` ruby
|
|
@object = Object.create!(:name => @name, :description => @description)
|
|
|
|
visit object_path(@object)
|
|
|
|
find_attribute(:name, @object.name)
|
|
find_attribute(:description, @object.description)
|
|
```
|
|
|
|
You can even make simple tables, a la Active Admin:
|
|
|
|
``` haml
|
|
#object
|
|
= attributes_table_for object do |f|
|
|
= f.field :name
|
|
= f.field :description
|
|
```
|
|
|
|
## Not Finding Things
|
|
|
|
Sometimes the absence of a thing is just as important as the presence of a thing. Make it easy on yourself:
|
|
|
|
``` ruby
|
|
# selector's not there
|
|
|
|
dont_find('#user')
|
|
```
|
|
|
