Null Known Value Checks

The known value checks that are available for null values are:

Null

`Null` Check

The Null check tests that a resource attribute, or output value has an exactly matching null value.

Example usage of Null in an ExpectKnownValue state check.

func TestExpectKnownValue_CheckState_AttributeValueNull(t *testing.T) {
    t.Parallel()

    r.Test(t, r.TestCase{
        // Provider definition omitted.
        Steps: []r.TestStep{
            {
                // Example resource containing a computed attribute named "computed_attribute"
                Config: `resource "test_resource" "one" {}`,
                ConfigStateChecks: []statecheck.StateCheck{
                    statecheck.ExpectKnownValue(
                        "test_resource.one",
                        tfjsonpath.New("computed_attribute"),
                        knownvalue.Null(),
                    ),
                },
            },
        },
    })
}
