[Twisted-Python] twistedchecker - Names of constant which are used as configuration options

[Adi Roiban]

Hi,

Why reviewing a patch I got into this error from twistedchecker.
This is old code, just that someone it was touched by recent changes,

C0103:574,12:NetstringReceiverTests.test_buffer: Invalid name
"MAX_LENGTH" for type attribute (should match
((([a-z_])|([a-z]+_[a-z]))[a-zA-Z0-9]+)$)

The code is like this, where TestNetstring is a line receiver
protocol... so MAX_LENGTH act as a configuration option.

            a = TestNetstring()
            a.MAX_LENGTH = 699

What to do in this case and how I can have  this code accepted by
twistedchecker?

Thanks!
