Introduction
Live code coverage quickly point to failure nodes for reproducible cases. To quickly train QA in the effectiveness of EMMA I have written a tool that mimics Russian Roulette. There are size buttons that call six methods one of which is at random chosen to fail.
Here is the walk though on how to find the method that fails via code coverage.
Walk through
http://qa1-nl.sakaiproject.org:82
Open the qa-helper in one browser window
Open the offending tool qa-fails in another browser window
Play the game until you have a reproducible case
Reset the EMMA session data in the helper tool
Reproduce the error in the failure tool
Generate a report in the helper tool
Review the reoprt and look for the partially run code in yellow
