More Control over system outputs

On Traceability and the Illusion
of Control

When I was 5 years old, my mother always
told me that happiness was the key to life.
When I went to school, they asked me
what I wanted to be when I grew up.
I wrote down ‘happy’. They told me I didn’t
understand the assignment, and I told
them they didn’t understand life.

Software testing is relentless
learning, continuous
improvement and keeping
abreast of cutting-edge
technologies.
The research and development
team at Exactpro uses machine
learning methods of intellectual
data analysis to create next-
generation program analysis
tools.
We work in an agile environment
collaborating with a multinational
team of software developers.

They told me I didn’t understand the
assignment and the test report does not
make anyone happy. I told them they
didn’t understand software testing.
Software testing is our life.

Demystifying DLT Testing One Network at a Time
Ekaterina Volobueva,
QA Analyst, Exactpro

The complexity of post-trade
- There is a multitude of components in modern
complex post-trade infrastructures;
- Upstream and downstream system dependency;
- The participant structure is very complex;
- Trade/Position/Account life cycle;
- The number of Asset Classes may vary;
- The complexity of the Risk calculation process;
- Access via a set of API endpoints.

Exactpro Test Framework and Test Approach for
DLT-based system
3 steps on the ledger side:
1st - Initialisation of positions
2nd - Trade creation and participant
notification
3rd - Positions updates
Across each and every step the test
framework provides different methods
to validate the endpoints, inputs and
outputs.
The actual business flow steps and
validation check items are transformed
into ClearTH matrix after execution of
which the deviations from the expected
behaviour can be analysed.

ClearTH and Woodpecker for DLT
is an Exactpro test harness able to simultaneously
execute multiple end-to-end test scenarios in
batches.
● Supports multiple protocols (SWIFT, FIX,
Market Data, etc.)
● Automatically runs test scripts
● Executes concurrent automated tests
● Allows to create multiple-day test scenarios
● Has integrated scheduler and simulators
● Verifies each stage of the system daily life cycle
