variable descriptor exposed as class attribute after the first class instantiation. #2000
Description
Reproducer:
class Foo(rfm.RegressionTest):
v = variable(int, value=1)
print(Foo.v) # Prints 1
Foo()
print(Foo.v) # Prints the variable descriptor object
Foo.v = 2
print(Foo.v) # Still prints the variable descriptor objectEven though this was tested for in the unit tests, the behaviour should be consistent regardless of the number of class instantiations.
In short, the variable descriptor should never be exposed like this and the variable's default value should be returned instead.
