php - The right way of starting Behat feature/story -

i'm starting bdd , after readings found out goes ddd.

now have domain, institution have places, added institution assignee user assigned manager of organization.

i still can't wrap head around how should be, feature sounds like: as assignee of institution must able add places organization

the code i'm thinking (sorry code-first approach) this:

if ($institution->isassignee($user)) {     $institution->addplace(/* properties*/); } 

now how should write feature , scenarios? should leave as assignee part , leave it? or should there multiple scenarios? how scenario like?

edit:

so left user permission check , started first feature followed specifications of implementation. code found here.

isn't feature simple? of course core of domain does, did not mentioned case in feature place same location not added, have done in institutionspec?

moving forward: if edit place of institution, better approach:

$place = $institution->getplace($placeid); $place->editwhatever(/***/); 

or

$institution->editwhateverinplace($placeid, /** edits **/); 

the check user have permission add place institution seems another's bounded context(bc) problem authorisation. check done in anticoruption layer in application layer outside institution aggregate querying authorisation bc create assignee user have role of "assignee".

in bc there assignee, possible implemented ad value object have userid , possible name.

p.s. bdd tests should split bc , furthermore aggregate.
