问题 I am trying to mock a class for phpunit. Php unit fails with the error Could not load mock ... class already exists .

There is a foreign key constraint that prevents the deletion of a company if sites have been assigned to it. If I attempt to delete the company with the ID 'KSL' using an SQL query directly on the database, I get the expected error: ERROR: update or delete on table "companies" violates foreign key constraint "sites_company_id_fkey" on table "sites" DETAIL: Key (company_id)=(KSL) is still referenced from table "sites".
