BugRaptors is a division of Seasia Group which perform testing of different types of domain for example marketing , finance, healthcare etc. Software testing is required to secure financial applications by implementing functional testing, security testing as well as automation testing because in this domain money is circulating by different payment methods.

1. Why Software Testing Is Very
Important For Banking
Applications?

2. Introduction
There is no association that can continue on the same pattern of services. It
has to change constantly as it is the key factor to the formation and success
of any association. In a similar fashion, there is a constant change in
financial Industry and it’s because of this constant change, IT companies
have to prefer a complicated design to develop financial applications to
ensure the application runs in a desired secure manner.
Any financial error is always the critical one. Workflow of every Financial
Application is always going to be complex. There is no association which
will tolerate any financial bug or error in their application. This is the part
where an association needs software testing and quality assurance. If
finances are involved in any application, guidelines have to be followed
strictly. Quality assurance and Software testing play a vital role here. Both
testers and developers of financial applications should have a good
understanding of finance and complete domain knowledge as well.

3. Most of the financial applications have different QA and software testing
necessities. A tester should have a proper domain knowledge in which the
financial application is based on. For Example, processing insurance
claims, online/mobile banking, trading accounting etc. A tester can only
proceed with testing activities if he/she has a good knowledge of the flow.
One of the most important steps is to make a test plan. In that very plan, it
states how various testing techniques such as functional, user acceptance,
product, performance, and security testing must be performed.
Specialized Testing services can also be used if the application flow is
very complex such as compliance testing, regulatory testing Data
Warehouse testing etc.

4. 1. A tester should involve in projects
from early stages
In my whole testing career and as per my understanding, requirements are
developed not collected. Firstly, Necessities and requirements are
discussed at the customer side, then at the company or Vendor side and
the communication continues for further necessities to work on. A tester
has to be part of the whole communication or should have a check on it
from the beginning. For Example, A Health insurance application may
have separate modules for transfers, Fee Module, Finance, bill payments,
Claims Payments Etc.
Peer Business Analysts, Development leads, QA Engineers and all the
stakeholders review the product delivered after collecting requirements.
They go through all the requirements so that neither new workflows nor
existing business workflow is violated.

5. They all make it sure that the scenarios are implemented in such a way
that all requirements from client side are covered. Business scenarios
should also cover the main flow of the application. High-level scenarios
also called as business scenarios.
After that Business Analyst reviews these Business Scenarios to make it
sure that all of the Business Requirements are fulfilled. High-level
scenarios are made because they are relatively easy for BAs to review
them.

6. 2. Thorough understanding of domain
as well as work flow of application
A tester must be aware of all the documents related to the project as well as
the requirements. If a tester will have good knowledge of the documents
and will be clear about each and every requirement only then he will be
able to cover every scenario.
A tester should have those SME skills which will help him to work
together with BAs and Programmers. It will all help testers to create a
mindset which will help them further in testing Financial Application.

7. 3. To cover all the possible scenarios
The third point is the test cases.
According to me, it is the most important part as far as Financial
Applications, Automated Payment Processing Systems are concerned.
More Pledge and Discipline is needed while creating test cases and even
more commitment is needed after creating test cases because requirements
keep on changing over time and test cases need to be updated as per the
updated requirements.
QA team has to run impact analysis to uncover the parts or zones which
can be impacted the most because of the defect fixes.
With the help of impact analysis, few more test cases can also be made to
cover the impacted areas. The process is also called selective re-testing
because this process focuses on reuse of pre-existing test cases which are
already executed.

8. 4. Importance of Performance and
Security testing
As we all know that
financial applications are
becoming more and
more API centric and
these days Banks have
their own Applications
running on the back of
APIs, Performance and
Security testing are most
important.

9. Commonly, performance testing is done to check if the application,
infrastructure can handle load which is fine but the code should also be
written keeping performance in mind. There are lots of examples where the
application is made high performing from load viewpoint but the code of the
application is not performing.
One of the most important points while testing any banking application is
Security Testing.
It makes banking applications more secure by facing and recognizing
security susceptibilities. Security testing also makes sure that application
fulfills Industry and Federal standards. Any web susceptibility can reveal or
leak sensitive information or data to an attacker or an invader and Security
testing makes it sure that it will not happen with help of standards like
OWASP (The Open Web Application Security Project).

10. 5. Importance of User Acceptance
Testing
User acceptance testing (UAT) can play important role in Efficient and
Effective testing of the financial application.
In general, Development or testing of any Financial Applications (High
Performing, Reliable, Secure and Functional) is not teamwork but multi-
functional teamwork in a healthy cooperated agile and technical
environment.
To help Testing, Development, Support team and the management to make
the right decisions at a right time, good testing psychology, great
communication skills and last but not the least functional testing skills is a
must for any software tester testing any financial applications.
