4. Quick Examples
• Company #1
•
•

•
42 Systems needed for E2E testing
Systems couldn’t talk because data didn’t match
Project teams added 15% more testing time for test data collection/creation
10% of tests could not be executed due to bad data
All defects had to be investigated as bad data first
•
•
Old data triggered many invalid defects
Some production defects existed because of unique data in production that wasn’t in a
test environment
• Company #2
•
•
•
•
•
Agile teams (6)
Used automation, ran tests every day/evening
Created business transactions as a part of testing
Transactions had a default renewal date
Actual renewal date hit, test environment came down as it tried to process all the
renewals
