Ruby Rspec : Testing instance variables without adding an accessor to source
Solution 1:
You can use Object#instance_variable_get method to get value of any instance variable of the object like that:
class Foo
def initialize
@foo = 5 # no accessor for that variable
end
end
foo = Foo.new
puts foo.instance_variable_get(:@foo)
#=> 5
And Object#instance_variable_set can be used to set instance variable values:
foo.instance_variable_set(:@foo, 12)
puts foo.instance_variable_get(:@foo)
#=> 12
