Public bug reported:

 - It asserts by checking if "exact json body" of created subnets(of
both private and shared networks ,which gets created in test case) is
present in output of "list_subnets(shared=X)['subnets']"  for
X=True/False.

Here, "priv" or "shared" is set to the body of subnet at the time of creation, later it checks for the presence of an exact match in the output of "list_subnets()".
However, if the vendor of plugin adds custom attributes/keys to subnets/networks, which may or may not get populated right at the time of creation, but at a later point in time. This causes a mismatch of subnet body and the test fails with  Mismatch_error.

As per the Tempest Design Principles, Tempest should be explicit in
testing features i.e, the test cases must be independent of the
implementation of Plugin by vendor and as the JSON/body{} of created
subnet depends on the vendor providing the plugin, so all assert
statements in this test case must be checked based on subnet[id].

Title:
  test_filtering_shared_subnets  - neutron tempest test case fails with
  "_impl.MismatchError"

Status in neutron:
  New

Bug description:
   - It asserts by checking if "exact json body" of created subnets(of
  both private and shared networks ,which gets created in test case) is
  present in output of "list_subnets(shared=X)['subnets']"  for
  X=True/False.

  Here, "priv" or "shared" is set to the body of subnet at the time of creation, later it checks for the presence of an exact match in the output of "list_subnets()".
  However, if the vendor of plugin adds custom attributes/keys to subnets/networks, which may or may not get populated right at the time of creation, but at a later point in time. This causes a mismatch of subnet body and the test fails with  Mismatch_error.

  As per the Tempest Design Principles, Tempest should be explicit in
  testing features i.e, the test cases must be independent of the
  implementation of Plugin by vendor and as the JSON/body{} of created
  subnet depends on the vendor providing the plugin, so all assert
  statements in this test case must be checked based on subnet[id].

  Test: neutron.tests.tempest.api.admin.test_shared_network_extension.SharedNetworksTest.test_filtering_shared_subnets[id-6661d219-b96d-4597-ad10-51672353421a]
