How to use the dimod.testing.assert_sampler_api function in dimod

def test_instantiation_smoketest(self):
        sampler = ClipComposite(NullSampler())
        dimod.testing.assert_sampler_api(sampler)

        dimod.testing.assert_sampler_api(sampler)

        # this sampler has no properties and has no accepted parameters
        self.assertEqual(sampler.properties, {})
        self.assertEqual(sampler.parameters, {})

        sampler = dimod.NullSampler()

        dimod.testing.assert_sampler_api(sampler)

        sampler = TruncateComposite(ExactSolver(), 10)
        dtest.assert_sampler_api(sampler)

def test_initialization(self):
        sampler = dimod.RandomSampler()

        dtest.assert_sampler_api(sampler)

        self.assertEqual(sampler.properties, {})
