[Answered ]-Django test in-memory SQLlite – missing tables during test run

Your cms.bulkimport.BaseContentBulkUploadForm is trying to execute a DB query at import time. In your trace Django is still in the process of discovering/building the test suite and has not yet created the test DB. You need to find the code which is executing the query on import (which looks like it’s m2m_column_help_text) and refactor it.
