Ignore missingType.iterableValue for data-providers

[staabm]

As we are now validating data-providers by its return/yield statements, I think we should no longer throw a

Method DataProviderIterableValueTest\Foo::dataProvider() return type has no value type specified in iterable type iterable.

error onto the PHPStan user

requires phpstan/phpstan-src#4488

This assumes an implementation detail that missingType.iterableValue is reported by a rule that hooks onto InClassMethodNode.

You can remove this instanceof and just ask for $scope->isInClass(), $scope->getFunction() etc.

got this code from the docs :).

doc-fix in phpstan/phpstan#13726

thank you.

BTW I love this, it's genius :)

@staabm @ondrejmirtes Is there an easy way to (?)

• take advantage of the DataProviderDataRule
• without enabling the DataProviderReturnTypeIgnoreExtension

Would it be ok to have such option ?

Maybe like

checkDataProviderData: %featureToggles.bleedingEdge% ignoreDataProviderReturnType: %featureToggles.bleedingEdge% PHPStan\Type\PHPUnit\DataProviderReturnTypeIgnoreExtension:	phpstan.ignoreErrorExtension: %phpunit.ignoreDataProviderReturnType% 

or

checkDataProviderData: %featureToggles.bleedingEdge% checkDataProviderReturnType: false PHPStan\Type\PHPUnit\DataProviderReturnTypeIgnoreExtension:	phpstan.ignoreErrorExtension: [%phpunit.ignoreDataProviderReturnType%, not(%phpunit.checkDataProviderReturnType%)] 

if such syntax exists...

In our codebase, we appreciate the fact PHPStan enforce the detailed phpdoc of iterable (for documentation purpose), and even if the return/yield statement are now checked, we still find some interest in the required phpdoc.

[ondrejmirtes]

So I realize I don't want to have a long-term option for turning off DataProviderDataRule. I only want it to be conditional now in 2.x based on bleedingEdge.

As for the data provider return types, I can imagine there to be an option named something like reportMissingDataProviderReturnType that would default to false. You could set it to true to disable the ignore errors extension.
