A
Business Analyst is involved in all the SDLC phases of a project. He begins his
job from Scoping & Requirements Gathering, then works on Optimizing
Solutions and Designing, then ensures a good product is Developed and
Implemented.
A
very critical part of the entire SDLC life cycle is testing. Regardless of the size of the project being
implemented or the type of industry that project impacts, there is nearly
always a testing phase to a project.
The
main focus of testing is:
- Finding faults in the system
- Ensuring that the system is acceptable to all users
- Testing the system with other systems
- Testing from a business perspective
Types
of testing performed by Business Analyst:
To
understand the different types of testing, let’s take an example of the IRCTC
Website. Assume the Business Analyst has built the website with 2 components:
Booking Module, Cancellation Module.
Component
testing
A
business Analys can test requirements in forms of components. Component are
software items for which independent requirements are given. Component testing is analogous to the unit testing methodology
but with advanced level of integration in the lexicon of application instead of
just testing it directly. In this type each component of software is tested on
an individual level by the Business Analyst.
Example:
This would be to test each component – Booking and Cancellation individually,
if it functions correctly or not.
Integration
testing
After
component testing, the next step a Business Analyst can look at is integration
testing. On performing component wise testing individually, they are
integrated. On integration, integration testing is performed to ensure that the
functionality is not broken. A business Analyst should ensure that on
integration, the modules continue to work as before.
Example:
To ensure that both Components when integrated work correctly.
Performance
testing
Many
users often access the system at the same time. A good Business Analyst ensure
that he thoroughly performs Performance Testing. Performance is measured in
terms of response time to a particular request, number of requests that can be
processed per second etc. We also need to ensure that the system can
efficiently handle multiple user requests within a stipulated time.
Example:
To test if the website works correctly even when 100 users login and try to
access the website together.
Security
testing
Security testing aims to provide protection or security to data in the system. It must eventually ensure that the data is kept highly secured and confidential and properly authenticated so as to ensure that the data is available at all times without affecting the content stored in it.
Security testing aims to provide protection or security to data in the system. It must eventually ensure that the data is kept highly secured and confidential and properly authenticated so as to ensure that the data is available at all times without affecting the content stored in it.
Example: This tests the user ID and login is secured.
No other user can misuse the credentials.
Database
testing
The
Database consists of data that your application dependent on. Thus the data
stored is most often mission critical and an important asset of the
organization. Database testing is performed on the database used in the
application. A Business Analyst need not get into technicality but needs to
make sure that the data is available accurately.
Example:
A Business Analyst needs to ensure that if 10 trains are stored in the
database, all of those are retrieved on the Booking page.
Functional
testing
Regression
testing is done on the changes made to the application to ensure that the older
functionality works the same way. Test scenarios are prepared for regression
testing and then the again the application is checked to ensure that it works
properly. A business Analyst helps in generating various test scenarios.
Example:
Functional testing is an essential part of the Business Analyst role; he must
generate various possible test cases to make sure all possible situations are
covered.
Most
of us must have experiences that particular software did not work. The impact
of faulty software can be huge considering that the organization may face loss
of money, loss of time and a damaged reputation. A business analyst is
responsible for the final product that is delivered; hence he must perform end
to end business testing of a product.
