Project background
One of the biggest risk
calculators in Bank
Sophisticated architecture
12 years of development
history
Problems
Not enough specifications
Release testing effort: full
regression test pack takes
approximately 1 man-year
Difficulties in sharing the
knowledge between locations
2
High level architecture

3. Russia Development Centre

For internal use only
Client - server distributed application
Collect data from upstream systems/feeds
Grid calculations
Orchestration
Reporting

Splitter feature
Key part of the solution
Helps to handle large volumes of
trades
Helps to break down calculations
into sub-calculations
Helps to parallelize execution over
multiple cores

Why was it failed?
Not everyone in the team bought it
Efforts considered to be the background tasks
Efforts were not properly planned in the beginning

8. Russia Development Centre

Target
Learn how to use SBE
approach in our environment
Test automation for existing
regression test pack
How to achieve?
Build a cross functional team
(QAs, DEVs, FAs)
Create a test automation
framework
Share results with teams
8
Second try

9. Russia Development Centre
Deutsche Bank
For internal use only
Test automation
Built a cross-functional test
automation team
Created a test automation
framework
Participated in release:
significant amount bugs were
found by test automation
Currently tests save: 30%
testing efforts
Current coverage: ~ 50% of
regression test pack
SBE
Regular demos and noise –
everyone aware about approach
efficiency
People have hands on
experience with SBE
Management bought the idea
Learnt how to plan and
manage the work with the new
approach
