# Douwe's diary New York City, 2016-06-28
|
|
# --------------------------------------------------------------------------
|
|
#
|
|
# Dear diary,
|
|
#
|
|
# Ideally, we would have a test for every single diff scenario that can
|
|
# occur and that the PositionTracer should correctly trace a position
|
|
# through, across the following variables:
|
|
#
|
|
# - Old diff file type: created, changed, renamed, deleted, unchanged (5)
|
|
# - Old diff line type: added, removed, unchanged (3)
|
|
# - New diff file type: created, changed, renamed, deleted, unchanged (5)
|
|
# - New diff line type: added, removed, unchanged (3)
|
|
# - Old-to-new diff line change: kept, moved, undone (3)
|
|
#
|
|
# This adds up to 5 * 3 * 5 * 3 * 3 = 675 different potential scenarios,
|
|
# and 675 different tests to cover them all. In reality, it would be fewer,
|
|
# since one cannot have a removed line in a created file diff, for example,
|
|
# but for the sake of this diary entry, let's be pessimistic.
|
|
#
|
|
# Writing these tests is a manual and time consuming process, as every test
|
|
# requires the manual construction or finding of a combination of diffs that
|
|
# create the exact diff scenario we are looking for, and can take between
|
|
# 1 and 10 minutes, depending on the farfetchedness of the scenario and
|
|
# complexity of creating it.
|
|
#
|
|
# This means that writing tests to cover all of these scenarios would end up
|
|
# taking between 11 and 112 hours in total, which I do not believe is the
|
|
# best use of my time.
|
|
#
|
|
# A better course of action would be to think of scenarios that are likely
|
|
# to occur, but also potentially tricky to trace correctly, and only cover
|
|
# those, with a few more obvious scenarios thrown in to cover our bases.
|
|
#
|
|
# Unfortunately, I only came to the above realization once I was about
|
|
# 1/5th of the way through the process of writing ALL THE SPECS, having
|
|
# already wasted about 3 hours trying to be thorough.
|
|
#
|
|
# I did find 2 bugs while writing those though, so that's good.
|
|
#
|
|
# In any case, all of this means that the tests below will be extremely
|
|
# (excessively, unjustifiably) thorough for scenarios where "the file was
|
|
# created in the old diff" and then drop off to comparitively lackluster
|
|
# testing of other scenarios.
|
|
#
|
|
# I did still try to cover most of the obvious and potentially tricky
|
|
# scenarios, though.
