UAHF Test Plan

Version 1.0, 2017-06-14


Introduction

This document is a rough draft of tests planned for UAHF as described in the UAHF Technical Specification [1].

Test cases listed below are currenty incomplete w.r.t. the revised technical specification - this document is very much under construction.

Functional Tests

TEST-1

If UAHF is disabled a large block is considered to break core rules, as is presently the case.

TEST-2

If UAHF is disabled, a regular block is accepted at or after the activation time (as determined by MTP(block.parent) without being considered invalid.

TEST-3

If enabled, a large block is considered excessive if all blocks have time < activation time.

TEST-4

If enabled, a large block B is not considered excessive if MTP(B.parent) >= activation time

TEST-5

If enabled, a large block B is not considered excessive if MTP(B.parent) < activation time, provided a prior block A has MTP(A.parent) >= activation time.

TEST-6

If enabled, a regular block R that is the first such that MTP(R.parent) >= activation time is considered invalid (satisfy REQ-3).

TEST-7

If enabled, a regular block R that is not the first such that MTP(R.parent) >= activation time is considered valid.

TEST-8

A small block more-work chain does not get re-orged to from a big block chain after activation has kicked in.

TEST-9

Test that enabling after being disabled renders a small chain going past activation invalid that was previously valid owing to it being disabled. And vice versa (enabled -> disabled).

TEST-10

If enabled, if a large but < 8MB block is produced, ensure that the degenerate case of sigops heavy instructions does not unduly affect validation times above and beyond the standard expected if UAHF is not enabled.

TEST-11

Test that linear scaling of 20,000 sigops / MB works for block sizes > 1MB (rounding block size up to nearest MB) (ref. BUIP040).

TEST-12

(similar to (TEST-9), but test interoperability of datadir with other clients.)

Test what happens when the unmodified BU / Core / other clients are used on a datadir where the UAHF client has been run. Should test again data from disabled (Core rules data, should be fine) , and enabled (big block data stored - may need to rebuild DB? or provide tool to truncate the data back to pre-fork block?)
