Changeset 7263 for main/waeup.sirp/trunk/src/waeup/sirp/applicants/interfaces.py

Timestamp:

4 Dec 2011, 12:59:40 (13 years ago)

Author:

Henrik Bettermann

Message:

Add tests for applicant batch importer.

Make reg_no filed unique.

Two tests still fail because the importer only accepts the application_number as location field and does not yet search for registration numbers.
