[tor-commits] [ooni-probe/master] Implement postProcessor NetTestCase hook for processing the results of all the test methods
commit 80e6e316e6c2d5344d34453ed2006fd239824dea
Author: Arturo Filastò <art@xxxxxxxxx>
Date: Fri Nov 23 19:41:41 2012 +0100
Implement postProcessor NetTestCase hook for processing the results of all the test methods
* Such methods gets passed a report dict that contains the reports of the
previous test runs keyed on the test method. This allows to implement
censorship detection logic that is cumulative to the running of all tests
* Refactor how we run tests to allow this hook to work. In particular all tests
methods are run before moving onto the next input.
* Add index for tracking the current input unit
