#subject ⇒ Object

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

The subject is used by all macros that require an instance of the class being tested.
