////////////////////////////////////////////////////////////////////////////////
// Tests for the filtering code of NNTP. The same tests are run for each of the
// different NNTP setups, to test code in a variety of cases.
//
// Different suites:
// * Perfect 3977 compliance (not tested)
// * Perfect 2980 compliance (XOVER and XHDR work)
// * Giganews compliance (XHDR doesn't work for practical purposes)
// * Only 977 compliance (no XOVER support)
// Basic operations:
// * Test that the following headers trigger:
//   - Subject
//   - From
//   - Date
//   - Size
//   - Message-ID (header retrievable by XOVER)
//   - User-Agent (header not retrievable by XHDR)
// * Test all actions
