Looks like this is a heavy-handed way to have the class's name method return TestIntegrationClass or something.

Is anything even referencing the constant TestIntegrationClass anywhere?

Is anything even referencing the constant TestIntegrationClass anywhere?

No, it's only a test to see if it fixes the issue. I'll definitly need your help to arrange this in a way that fit ruby idioms.

[lloeki]

This is one of the ways to remove the standard #<Class:0x12345> stringification of dynamic classes.

There's also to_s that might end up being used, and self.name. Maybe self.to_s and self.inspect as well.

Which one you think is the best fit ?

[p-datadog]

You can define classes the old-fashioned way: https://github.com/DataDog/dd-trace-rb/blob/master/spec/datadog/di/serializer_spec.rb#L5

But, I don't know what you are attempting to achieve with this PR.
