Pony ORM lambda or generator expression function is marked as unexecuted

Hi, Here a small matter I have with ponyorm. In ponyorm you can make query to database with lambda or generator expressions. those 2 thing are equivalent :

return Praticien.select(lambda p: p.nom_d_exercice.lower().startswith(chaine.lower()))
return select(p for p in Praticien if p.nom_d_exercice.lower().startswith(chaine.lower()))

html report says :port says :

The line 98 didn't finish lmabda on line 98 or lne 98 didn't run generator expression in line 98

seems that smaller expression are ok :

Praticien.select()

I really would help to try fix it but I do not know where to start

Thank you Jimmy

Some other possibilities of how to handle this more gracefully:

1. You can set the coverage.py pragma regex so that some lines are automatically pragma’d:

   [report]
   partial_branches = 
       pragma: no branch
       \.select\(lambda
   

   Now any line that matches either of the two regexes will be considered partial-branch, so your line is recognized even without a comment.

2. You can separate the definition of the lambda or generator expression from the line that uses them:

   to_select = lambda p: p.nom_d_exercice.lower().startswith(chaine.lower())    # pragma: no branch
   return Praticien.select(to_select)
   

   or:

   to_delete = (j for j in MyEntityClass if j.deleted == True)  # pragma: no branch
   delete(to_delete)
   

   This isolates the non-run code to its own line, so you don’t run the risk of turning off coverage measurement on a line that truly needs it.

Hello,

See this: https://stackoverflow.com/questions/53280985/how-to-ignore-ponyorm-generator-expressions-in-nose-tests-coverage/53281148#53281148

I’ve tried to solve is with #pragma: no branch, it works some time. but some time you need to also use #pragma: no coverage
