Disables warning messages about expectations being set on nil.
By default warning messages are issued when expectations are set on nil. This is to prevent false-positives and to catch potential bugs early on.
Creates an instance of RSpec::Mocks::Mock.
`name` is used for failure reporting, so you should use the role that the mock is playing in the example.
Use `stubs` to declare one or more method stubs in one statement.
@example
book = double("book", :title => "The RSpec Book") book.title #=> "The RSpec Book" card = double("card", :suit => "Spades", :rank => "A") card.suit #=> "Spades" card.rank #=> "A"
Stubs the named constant with the given value. Like method stubs, the constant will be restored to its original value (or lack of one, if it was undefined) when the example completes.
@param constant_name [String] The fully qualified name of the constant. The current
constant scoping at the point of call is not considered.
@param value [Object] The value to make the constant refer to. When the
example completes, the constant will be restored to its prior state.
@param options [Hash] Stubbing options. @option options :transfer_nested_constants [Boolean, Array<Symbol>] Determines
what nested constants, if any, will be transferred from the original value of the constant to the new value of the constant. This only works if both the original and new values are modules (or classes).
@return [Object] the stubbed value of the constant
@example
stub_const("MyClass", Class.new) # => Replaces (or defines) MyClass with a new class object. stub_const("SomeModel::PER_PAGE", 5) # => Sets SomeModel::PER_PAGE to 5. class CardDeck SUITS = [:Spades, :Diamonds, :Clubs, :Hearts] NUM_CARDS = 52 end stub_const("CardDeck", Class.new) CardDeck::SUITS # => uninitialized constant error CardDeck::NUM_CARDS # => uninitialized constant error stub_const("CardDeck", Class.new, :transfer_nested_constants => true) CardDeck::SUITS # => our suits array CardDeck::NUM_CARDS # => 52 stub_const("CardDeck", Class.new, :transfer_nested_constants => [:SUITS]) CardDeck::SUITS # => our suits array CardDeck::NUM_CARDS # => uninitialized constant error
