Module | Shoulda::InstanceMethods |
In: |
lib/shoulda/context.rb
|
Returns an instance of the class under test.
class UserTest should "be a user" do assert_kind_of User, subject # passes end end
The subject can be explicitly set using the subject class method:
class UserTest subject { User.first } should "be an existing user" do assert !subject.new_record? # uses the first user end end
If an instance variable exists named after the described class, that instance variable will be used as the subject. This behavior is deprecated, and will be removed in a future version of Shoulda. The recommended approach for using a different subject is to use the subject class method.
class UserTest should "be the existing user" do @user = User.new assert_equal @user, subject # passes end end
The subject is used by all macros that require an instance of the class being tested.
