Description

Currently, we have TypeInfoTestCoverageTest which checks that we have a test that extends TypeInformationTestBase for all type infos. But TypeSerializer doesn’t have the same thing that would verify that TypeSerializer has tests that extend SerializerTestBase and TypeSerializerUpgradeTestBase. Therefore we don’t know if test coverage of TypeSerializer is good.

This would add TypeSerializerTestCoverageTest to check whether to have tests based on SerializerTestBase and TypeSerializerUpgradeTestBase because all serializers should have tests based on both of them.
