#must(matcher, subject = @subject || subject(), msg = nil) ⇒ Object

Facilitator to assert_must for use with minitest-spec. If no subject given, defaults to matching against the current ‘subject` or the instance variable `@subject`.

Example:

subject { Order.new }

it "should have associations" do
  must belong_to :account
  must have_many :line_items
end

def must(matcher, subject = @subject || subject(), msg = nil)
  assert_must matcher, subject, msg
end

#wont(matcher, subject = @subject || subject(), msg = nil) ⇒ Object

Facilitator to assert_wont for use with minitest-spec. If no subject given, defaults to matching against the current ‘subject` or the instance variable `@subject`.

Example:

subject { User.new }

it "should validate" do
  wont have_valid(:email).when("foo", "foo@bar", "@bar.com")
end
