With the gdev, I can obtain the ud and identity parameters with :

const parameters = await api.query.Parameters.ParametersStorage.getValue()
    expect(parameters).toMatchInlineSnapshot(`
      {
        "babe_epoch_duration": 30n,
        "cert_max_by_issuer": 10,
        "cert_min_received_cert_to_issue_cert": 2,
        "cert_period": 15,
        "cert_validity_period": 1000,
        "distance_evaluation_period": 1000,
        "idty_confirm_period": 40,
        "idty_creation_period": 50,
        "membership_period": 1000,
        "membership_renewal_period": 500,
        "smith_cert_max_by_issuer": 8,
        "smith_inactivity_max_duration": 48,
        "smith_wot_min_cert_for_membership": 2,
        "ud_creation_period": 60000n,
        "ud_reeval_period": 600000n,
        "wot_first_cert_issuable_on": 20,
        "wot_min_cert_for_create_idty_right": 2,
        "wot_min_cert_for_membership": 2,
      }
    `)
  })

But I can't get this parameters with the gtest (spec_version: 1000). How to get this info ?
