This feature is aimed to provide a new way to debug applications during
scenarios playing.
When a difference happens between two shots of an application, the
investigation can be tough as the cause may be hidden into a tiny
change, such as an update of the theme.
This feature tries to respond to this problem by storing objects of
the application every time a shot is taken. Then during shots comparison,
objects information are compared and differences are displayed on the
screen.
The feature can be used with the -S option.
For the moment, only hierarchy, order and geometry are checked.
During recording, hooking on Evas functions can't work anymore as they
are no more invoked internally.
The new way to catch the events is to listen to them on the canvas.
Additionally, regular mouse events are now multi events whose tool (device id)
is 0, as well as key events with and without keycode are now always
considered with a keycode that can be 0.
Previous events catching has been kept to support legacy applications.
An issue that currently happens in Exactness is that we don't have any
way to debug the recordings.
Only debug information can help us to figure out what data is stored
inside the rec files.
Three commands are available:
- Clean: remove bad timestamp events and duplicate events
- Add a delay: because of the first event is directly treated if no
first timestamp is present, we need a way to fix recordings by adding
them a delay before the first event.
- List information: display the list of events, as vieet doesn't work at
all. Really helpful to figure out bugs.
