Hello Martin,

currently it is just a very simple aproach to make flickering tests behave more stable and 
to prevent error message flooding.

Currently there is no visual representation of the number of tests wich was needed to run 
ok so the setting only makes sense for tests where a singular failure means nearly nothing 
and can be ignored.

For more complex rules we're thinking about implementing Aggregation Strategies as 
Services. So maybe a single test will fail but the Aggregator will only turn red if the 
test failed 5 times in a row. This has to be detailed in future. I added ticket 
http://forge.typo3.org/issues/show/5197 for this.

Regards Martin
