Exmaple:

    def test_when_fully_specified_bfd_parcel_expect_successful_post(self):
        # Arrange
        bfd_parcel = BFDParcel(
            parcel_name="BFDFullySpecified",
            parcel_description="BFD Parcel",
        )
        bfd_parcel.set_muliplier(1)
        bfd_parcel.set_poll_interval(700000)
        bfd_parcel.set_default_dscp(51)
        bfd_parcel.add_color(color="lte", hello_interval=300000, multiplier=7, pmtu_discovery=False)
        bfd_parcel.add_color(color="mpls", pmtu_discovery=False)
        bfd_parcel.add_color(color="biz-internet")
        bfd_parcel.add_color(color="public-internet")
        # Act
        parcel_id = self.session.api.sdwan_feature_profiles.system.create(self.profile_id, bfd_parcel).id
        # Assert
        assert parcel_id
