Function Documentation

TEST() [1/13]

TEST	(	TestGeometryPublication	,
		AChangeToAnyPublishedFieldIsADifference	)

TEST() [2/13]

TEST	(	TestGeometryPublication	,
		AMeasuredGeometryStillCarriesItsRectangle	)

A measured geometry keeps every pixel it always had, so the omission above cannot start applying to a stream that has a frame.

TEST() [3/13]

TEST	(	TestGeometryPublication	,
		AnOverrideIsWithdrawnByZeroOrNullWithoutEndingPlayback	)

TEST() [4/13]

TEST	(	TestGeometryPublication	,
		ANullFieldIsNotAWithdrawal	)

TEST() [5/13]

TEST	(	TestGeometryPublication	,
		ARefusedMeasurementIsDistinguishableOnTheWireFromNoneAtAll	)

Both of these serve the frame and both report container. If the serialised form did not carry the rejection, a consumer could not tell the file that needs measuring from the one whose detector failed on it.

TEST() [6/13]

TEST	(	TestGeometryPublication	,
		AShapeWithNoFrameIsSerialisedWithoutAnyPixels	)

What Kodi reports while nothing is playing. There is no picture and no resolution behind one, so a rectangle here would be invented - and zeros are a rectangle a consumer can act on, which is why the fields are absent rather than empty.

TEST() [7/13]

TEST	(	TestGeometryPublication	,
		NothingStatedChangesNothing	)

TEST() [8/13]

TEST	(	TestGeometryPublication	,
		OsdPlacementNamesTheTwoThingsItCanBeLaidOutAgainst	)

TEST() [9/13]

TEST	(	TestGeometryPublication	,
		SectionsReachTheSerialisedForm	)

varies says one rectangle does not describe the title; the sections are what a consumer acts on it with, so the two must not be able to disagree about whether they are there.

TEST() [10/13]

TEST	(	TestGeometryPublication	,
		StatingOneOverrideLeavesTheOthersAlone	)

TEST() [11/13]

TEST	(	TestGeometryPublication	,
		ThePublishedRatioIsRoundedToTheVocabularysPrecision	)

A float widened to a double serialises as sixteen digits of its own representation error, which a caller cannot compare against the ratio it asked for.

TEST() [12/13]

TEST	(	TestGeometryPublication	,
		TheSectionsArrayIsWrittenEvenWhenNothingWasMeasured	)

An unmeasured file has no sections, and the array is still written - an absent one would be a third state on top of the empty one.

TEST() [13/13]

TEST	(	TestGeometryPublication	,
		WhatWasDrawnIsSerialisedAsTwoRectangles	)

Both rectangles, because they answer different instructions: a mask is driven to the lit picture and a lens to the area Kodi is operating in, and the two coincide only when the content is exactly the shape of the room.
