Ichthyostega 292be817b7 Timeline: investigate problem with numeric overflow in fractional arithmetic Extensive tests with corner cases soon highlighted this problem inherent to integer calculations with fractional numbers: it is possible to derail the calculation by numeric overflow with values not excessively large, but using large numbers as denominator. This problem is typically triggered by addition and subtraction, where you'd naively not expect any problems. Thus changed the approach in the normalisation function, relying on an explicitly coded test rather, and performing the adjustment only after conversion back to simple integral micro-tick scale.		2022-11-07 00:19:28 +01:00

GUI backbone tests

The tests in this subtree are a bit special: they cover the generic and
backbone internals of the Lumiera GTK GUI. They are linked against the
complete GUI-module (gui plugin), and thus may use all related ABIs.

Yet these tests are *deliberately* compiled without any GTK, GTKmm or SigC
includes. This effectively rules out the use, even indirectly, of any GTK
widgets and APIs -- forcing the covered GUI backbone entities to stay
clean and generic at API level.

This is a decision done on purpose. The concrete GUI framework technology
shall be treated as an implementation detail. There is no point in writing
tests which click buttons in the GUI -- better delegate any significant
logic or functionality to GUI agnostic components. GUI is meant to be
a presentation layer and must not develop intelligence on its own.
