Test suite: background snapshot improvements
Originally created by Tails on #6094 (Redmine)
While background snapshots are invaluable for speeding up the test suite and not hammering the Tor authorities excessively with complete bootstraps, they do introduce some ugly code overhead and confusion:
- There’s the need of the
I save the state ...
step at the end of the Background, which is pretty hackish. - Each "skippable" step needs an
next if ...
line around the top of the step. - In the previous point I say "around" the top, because
sometimes input from a step are to be saved in some global variable
to be accessible for subsequent steps, and then those assignments
should happen before the
next if ...
. It’s pretty confusing.
It’d be great if we could tag steps skippable
and skip them when
appropriate using something like an AroundStep('
skippable’)@ hook, but
vanilla cucumber supports neither tagging of steps nor such a hook
(cucumber-cpp does, though).
OTOH, with all that we’d be unable to save any input from the skipped
steps, which probably would require some interesting workarounds (maybe
using real $global
variables instead of class variables will do?).
So the question is if we really can improve the situation. An
AfterBackground('
snapshot’)@ hook would at least be nice for killing
the I save the state ...
step in features tagged @snapshot
. Can this
be implemented using formatters, e.g. like our custom
{After,Before}Feature
hooks in features/support/extra_hooks.rb
?
