Ruby assertions and disabled inputs

cucumberruby-on-railstestunitwebrat

Does anyone know how to assert that a checkbox or input is disabled? I can't find anything to indicated that this is supported
I'm writing cucumber tests with webrat and test/unit.

I'd like to have a step that is able to assert_disabled :some_checkbox || assert_disabled :some_input.

Or some way that I can check a property of the checkbox.

Then /^the "([^\"]*)" field should be disabled$/ do |label|
  field_labeled(label).should be_disabled
end

should do it for you.

Ruby-on-rails – How to understand nil vs. empty vs. blank in Ruby

.nil? can be used on any object and is true if the object is nil.

.empty? can be used on strings, arrays and hashes and returns true if:

String length == 0
Array length == 0
Hash length == 0

Running .empty? on something that is nil will throw a NoMethodError.

That is where .blank? comes in. It is implemented by Rails and will operate on any object as well as work like .empty? on strings, arrays and hashes.

nil.blank? == true
false.blank? == true
[].blank? == true
{}.blank? == true
"".blank? == true
5.blank? == false
0.blank? == false

.blank? also evaluates true on strings which are non-empty but contain only whitespace:

"  ".blank? == true
"  ".empty? == false

Rails also provides .present?, which returns the negation of .blank?.

Array gotcha: blank? will return false even if all elements of an array are blank. To determine blankness in this case, use all? with blank?, for example:

[ nil, '' ].blank? == false
[ nil, '' ].all? &:blank? == true
