Description

If there is a class with some fields hidden and we need to access these fields inside tests, the generated code is incorrect.

To Reproduce

Launch HiddenFieldExampleTest or HiddenFieldAccessModifiersTest (you should enable testingCodeGeneration by editing lines under the TODOs)

Expected behavior

Tests passed.

Actual behavior

Generated code is incorrect (in one case it is not compilable, in the other it has wrong tests).

Additional context

This is a sub-issue for #563, look there for more information and examples
