"My method stub only works on the first RSpec example and clearing in subsequent examples, what's wrong?"
Using RSpec, it is common to mock out certain aspects of your code to change functionality for testing. This is accomplished using the "stub" method and passing the method name as a symbol.
SomeObject.stub(:some_method_to_modify).and_return do something_else() end
As we like to keep our code nice and DRY, we often pull things into "before" blocks. Unfortunately, this can cause some confusion as
describe "ObjectA" do
before :all do
ObjectB.stub!(:some_method_ObjectA_depends_on).and_return(15)
end
it "can test something" do
...
end
it "can test something else" do
Objectb.some_method_ObjectA_depends_on
end
end
will have ObjectB.some_method_ObjectA_depends_on actually executing ObjectB's method instead of stubbing. This is because after each example ("it" block), all stubs are cleared from all objects, leaving the stubs only effective in the first example.

"Does anyone know of the best current Date-Time picker for Javascript?"
*Tim Harper's Calendar Date Select was recommended for its simplicity and rails integration.

sudo gem install calendar_date_select
config.gem "calendar_date_select"
And insert into your Rails code:
<%= calendar_date_select_includes "red" %>
And voila, you have an intuitive time and date selector:
