Me
My name is Jean-Paul Varwijk
I started testing in 1998 as a user, testing the Euro, the millennium bug etc. Became a fulltime tester in 2004
I spent part of my spare time on testing by writing about testing, giving presentations or doing workshops.

ISTQB
I will use a part of the ISTQB syllabi as a reference to explain my approach
I chose ISTQB because even if you do not use it yourself their content is widely known and regularly used in some form or another

Testing objectives
According to the ISTQB foundation syllabus, testing has the four following objectives:
Finding defects
Gaining confidence about the level-of-quality
Providing information for decision making
Preventing defects

ISTQB on defects
Presence, removal or absence expresses quality
Numbers found, fixed and duration measures quality ( of the testing process)
Broken down by severity and priority
Analysis at the end of the project
(to determine process improvement possibilities)

Me on defects
Information about the product
Something to investigate
Information about impact on the value of the product
Should be persuasive

ISTQB on prevention
Setting up the process
Getting complete and correct requirements
Review
Design and script test cases (upfront)

Agree mostly on requirements and review and partially on process
Setting up communication

Testing & Finance
Testing = Testing
Direct banking, ATM are similar
Many back office or internal systems are different
Different playing field – Different demands

Me and SOx
SOx has a typical information objective
It requires information on all changes within the financial institution that have an impact on the annual balance
It specifically is concerned with changes in financial (risk) models
![Page 29: Financial Software Testing - WordPress.com · Intro The presentation will show how I see Financial Software Testing I will start with testing in general by using ISTQB as a reference](https://reader031.vdocuments.mx/reader031/viewer/2022030902/5b40327b7f8b9a91078d072a/html5/thumbnails/29.jpg)
IT and SOx
No financial organization applies or changes these models without the usage of software
The typical response for this is to create change management processes with strict standards, procedures, deliverables and controls
Sounds a bit like ISTQB…
![Page 30: Financial Software Testing - WordPress.com · Intro The presentation will show how I see Financial Software Testing I will start with testing in general by using ISTQB as a reference](https://reader031.vdocuments.mx/reader031/viewer/2022030902/5b40327b7f8b9a91078d072a/html5/thumbnails/30.jpg)
SOx and me
Contacted the SOx team directly
Checked interest in the process
Asked for deliverables and what should go into them
Agreed on the timeline
![Page 31: Financial Software Testing - WordPress.com · Intro The presentation will show how I see Financial Software Testing I will start with testing in general by using ISTQB as a reference](https://reader031.vdocuments.mx/reader031/viewer/2022030902/5b40327b7f8b9a91078d072a/html5/thumbnails/31.jpg)
Result
Identify test objects to cover functionality
Log tests and test results for each object
Link tests and test objects to the existing
structure used for change management
If tests have not passed either there is a logged defect
or other recorded decision by the stakeholder
