Some helpers for poking around at your Capybara driven browser's cookies in integration tests.

Supports Capybara's bundled drivers (rack-test, Selenium Webdriver), and adapters for other drivers may be added.

Possible Reason 1: parallel_tests - running more processes than features

If you run old versions of parallel_tests with more processes than you have Cucumber features, you will get errors like this in unexpected places:

This is a bug caused by multiple processes running the same features on the same database.

The bug is fixed in versions 0.6.18+.

The step definition below lets you say:

 Then I should see a field "Password"
 But I should not see a field "Role"

Here is the step definition:

Then /^I should( not)? see a field "([^"]*)"$/ do |negate, name|
  expectation = negate ? :should_not : :should
  begin
    field = find_field(name)
  rescue Capybara::ElementNotFound
    # In Capybara 0.4+ #find_field raises an error instead of returning nil
  end
  field.send(expectation, be_present)
end

Note that you might have to adapt the step defi...

Look up HTML5 features, know if they are ready for use, and if so find out you should use them – with polyfills, fallbacks or as they are.

Gem to get Rails 3's new ActiveRecord query interface (where, order) and the new scope syntax (chaining scope definitions) in Rails 2.

You also get #to_sql for scopes.

Gem to get Ruby 1.9 features in Ruby 1.8.

Removing features and merging those changes back can be painful. Here is how it worked for me.\
tl;dr: Before merging back: reinstate reverted features in a temporary branch, then merge that branch.

Scenario

Consider your team has been working on several features in a branch, made many changes over time and thus several commits for each feature.\
Now your client wants you to deploy while there are still stories that were rejected previously and can't be deployed.
...

In cucumber you are able to run features in whatever directory you like. This also includes executing features in subdirectories. There are only some things you have to take care of.

By default, cucumber loads all *.rb files it can find (recursively) within the directory you passed as argument to cucumber.

$ cucumber # defaults to directory "features"
$ cucumber features
$ cucumber my/custom/features/dir

So, if you would like to organize features in subdirectories, you won't have *any problems when running the whole test...

This is for you if you get this error:

cucumber.yml was found, but could not be parsed. Please refer to cucumber's documentation on correct profile usage.

Actually, it's likely that your cucumber.yml is just fine but not your rerun.txt.\
This sometimes happens when running multiple Cucumber workers with parallel_tests that write into rerun.txt simultaneously -- ending up with a messy, invalid file.

Just remove it and you ar...

In your Cucumber features you can't really click hidden elements when using Selenium (it does work for a plain Webrat scenario, though).

Unfortunately you need to hack around it, like this:

When /^I press the hidden "([^\"]+)" submit button$/ do |label|
  page.evaluate_script <<-JS
    $('input[type=submit][value="#{label}"]').show().click();
  JS
end

If your button is nested into a container that is hidden this will not do the trick. You need a more complex method to also show surrounding containers:

When /^I pre...

After my update from MacOS X 10.6 Snow Leopard to 10.7 Lion the search function in Apple Mail stopped working.
There were no or too little search results, when I typed something in the search field.
It looked like my mailboxes couldn't be indexed by spotlight anymore.

And here is the simple solution:

1. Mark your mailbox in the list of mailboxes on the left in your apple mail window by clicking on its name once.
2. From the menu select "Mailbox" => "Rebuild".
3. After the rebuild you should get the right search results again.
4. Proceed wi...

Submit buttons in Rails come with a useful option :disable_with which will disable the button when clicked and change its label to something like "Please wait...".

An annoying side effect of that feature is that when you use the back button to return to the form, the submit button will be greyed out and disabled.

A solution is to re-enable the submit button before leaving the page. This works in Rails 3:

$(window).unload(function() {
  $.rails.enableFormElements($($.rails.formSubmitSelector));
});

Framework to write command-line apps in Ruby. Comes with a nice way of processing parameter options, some utility classes and Cucumber steps for testing your CLI app.

When you have a complex recipe setup with multistage deployment you may run into this error:

`role_list_from': unknown role `something' (ArgumentError)

Consider this task definition:

namespace :foo do
  task :bar, :roles => :something do
    # do crazy stuff
  end
end

Whenever we call foo.bar in our recipe, Capistrano will fail if you deploy to a stage where none of the servers has the role the error complains about, "something" in this case.

However, you can [hack around it](http://groups.google.com/group/ca...

Scenario outlines allow us to more concisely express repetitive examples through the use of a template with placeholders.

Using rename_column, remove_column, etc. more than once in a migration makes that migration run slower than it should. Use change_table instead.

Consider this migration:

add_column :users, :name, :string
remove_column :users, :first_name
remove_column :users, :last_name
rename_column :users, :cool, :awesome

Migrating in this case means that all those commands are processed step by step, causing 4 SQL statements to change the table. In turn, your database needs to modify the table structure 4 times. When working on hu...

I have a pair of headphones connected to my desktop's back panel and a headset connected to the front panel. I used to play sound over both outputs, but this suddenly stopped working this week.

Apparently, (perhaps through some update) "jack sensing" got turned on, which disables the back panel as soon as you connect something to your front panel audio jack.

To disable this feature, I used alsamixer (use the arrow keys to navigate right to "auto mute", and disable with the up key). For some reason the corresponding checkbox in the `gnome...

If you get the above error when running tests in bulk (but not individually), it's actually the fault of Webmock.

Updating Webmock to version 1.7+ fixes this.

ActiveSupport's memoize has a dangerous feature you might not know about.

Assume you have

class DeepThought
  extend ActiveSupport::Memoizable

  def life_universe_and_everything
     # some lengthy calculation returning 42
  end
  memoize :life_universe_and_everything
end

Then #life_universe_and_everything will of course cache the result after calculating it once. However, you can trigger a recalculation by calling #life_universe_and_everything(true).

If, however, your method looks like

If you get an error like this:

Unable to launch /home/bruce/Projects/myproject/tmp/capybara/capybara-201110311210111407691101.html 

... update your launchy gem. It failed for us in version 0.4.x. We could fix the issue by upgrading to 2.0.5.

If you encounter the error message above when running cucumber, just execute...
rm rerun.txt
...in the Rails directory.

Or run...
tests
...from the geordi gem. This will do the work for you automatically.

RSpec 1 (Rails 2)

With the most recent spec_candy.rb helpers you can say:

User.stub_any_instance(:foo => :bar)
user = User.new
user.foo
# => :bar

RSpec 2 (Rails 3)

RSpec 2 comes with this feature built in:

User.any_instance.stub(:foo => :bar)
user = User.new
user.foo
# => :bar

RSpec 3

The solution in this card is based on a stack overflow post by Leventix.

If you need to make request come from a fixed IP address for the duration of a Cucumber scenario, the code below lets you write this:

Given my IP address is 188.174.117.205

Rails 3

Given /^my IP address is "(.*?)"$/ do |ip|
  ActionDispatch::Request.any_instance.stub(:remote_ip).and_return(ip)
end
