+## Tests made
+Changes on colnod are made by [Colnod client](https://spaceti.atlassian.net/wiki/spaces/IN/pages/194576388/Colnod+client)
+
+Changes on db can be made by sql commands directly or by [pgAdmin](https://www.pgadmin.org/)
+- add token to db/colnod (2 tests)
+- edit token in db/colnod (2 tests)
+- delete token from db/colnod (2 tests)
+- add subject to colnod
+- edit subject in colnod
+- delete subject from colnod
+- edit same token on both db/colnod (diffrent time)

+- 2892 tokens updated
+- 173 tokens deleted
+- 2894 subjects updated
