He wrote the Test Strategy of the Tax & Revenue Management solution based on the V-model for testing.
This strategy defines that testing activities should be executed in phases according to the construction strategy.
This model is applied when high reliability is required.
18. Testing
Examples, tools & techniques
Testing activity Goal Owner/Characteristics
Unit testing Testing of each code line or function to
guarantee that it woks as a unique part.
Developer
Use of Test Scripts is optional
Test are applied in development servers
Functional testing Testing of each function, program and
module to guarantee that it woks as a
unique part.
Developer, with the participation of the business
analyst
Use of Test Scripts is optional (but recommended)
No need of a Test Management tool
Test are applied in quality assurance servers
Integral testing Test all modules and the interfaces
between modules that support end2end
business processes (i.e, from tax filling to
general ledger, or from general ledger
module to debt case manager).
Client’s staff with the support of a business analyst
that acts as test manager
Use of Test Scripts is mandatory. Test scripts
should be defined by client’s staff
A Test Management tool is mandatory to track
status of each test script
An Incident Management tool is highly
recommended, so testing users can report
errors/incidents and create a ticket and a help desk
request for each error detected.
Test are applied in quality assurance servers (3
testing cycles, meaning each test script is applied 3
times
User Acceptance Tests Test all modules and the interfaces
between modules that support end2end
business processes.
Qualifying each test script as “Ok” or
“successful“ means that the solution is
technically ready to Go live in production
servers.
Client’s staff with the support of a business analyst
that acts as test manager
Use of Test Scripts is mandatory. You use the
same test scripts defined for Integral Testing
A Test Management tool is mandatory to track
status of each test script
Test are applied in preproduction servers (or in
quality assurance servers if no preproduction
landscape is available). Only one testing cycle.

Examples, tools & techniques
Test Script example
The whole porpuse is to predefine a script with detailed steps, actions, expected
results and a registry of the real result (Ok means real result is equal to expected
result).
