Banking Application Testing: Main Steps

by TestFortExpert on 01/31/2012

Banking applications are often considered as one of the most complex and large software systems in today’s development and testing practice. The question is “why?”. And what method should be accepted in order to provide their quality and successful testing. This post is going to tell you about the stages and methods of testing Banking applications.

As we were talking earlier, Banking apps are very complex ones, so they have a lot of different characteristics. The main ones we are going to observe here:

Multi level functionality that allows to support thousands or even millions of users
Large scale integration: usually banking applications are integrated with a number of other apps
A complexity of business workflows
Real time processing
High density of transactions
High level of transactions security
Strong reporting section to keep information about transactions saved
Strong auditing system for preventing customer problems
Massive data storage system
Disaster management

Talking about banking application testing we should consider that it takes a lot of time because it needs an end to end testing method that involves different software testing techniques.

How to test banking applications?

1. Requirement Gathering

This stage involves documentation of all requirements such as Functional Specifications and User Cases. These requirements are gathered as per customer necessary things. All of them are documented by Banking Experts and Business Analysts.

2. Requirement Review

The results of the previous stage are reviewed by all the members of the testing process: QA Engineers, Business Analysts and Development leads. Their purpose is to check that both existing and new workflows are not violated.

3. Preparing Of Business Scenarios

When all the requirements are documented and checked, QA Engineers use them to derive Business Scenarios. This has to be done in order to cover all the Business Requirements. These scenarios don’t include any detailed steps being high-level scenarios. Then they are reviewed by Business Analyst who checks if all the requirements are satisfied. It has to be noticed that it’s easier for Business Analyst to review high-level scenarios than low-level Testing Cases.

4. Functional Testing

The first thing to do is to derive Test Cases from Business Scenarios. One Business Scenario usually includes several positive and negative Test Cases. These cases are reviewed by QA Engineers and then all the cases are executed. The execution can be either manual or automated that involves such tools as QC, QTP and others.

5. Database Testing

One of the most important stages in Banking application testing is database testing. As database is a complicated and separated layer of the system, its testing should be done very carefully. The main aspects to be ensured in database testing are:

Data loading
Testing of data types and DB Schema
Rules testing
Database migration
Testing triggers
Testing storing and functions
Data integrity

6. Security Testing

This type of testing is usually the last step in Banking application testing. This is one of the most important stages in the application testing cycle as it ensures that application is secure about data loss and different kinds of attacks. We have already written about security testing techniques, so we are only going to recommend some common security testing tools.

The whole application scan by security issues could be done using such tools as IBM Appscan and HP WebInspect. You can also use such manual tools as Http Watch, Paros Proxy and others.

We Work With

Having one outside team deal with every aspect of quality assurance on your software project saves you time and money on creating an in-house QA department. We have dedicated testing engineers with years of experience, and here is what they can help you with.

Software is everywhere around us, and it’s essential for your testing team to be familiar with all the various types and platforms software can come with. In 21+ years, our QA team has tested every type of software there is, and here are some of their specialties.

There are dozens of different types of testing, but it takes a team of experts to know which ones are relevant to your software project and how to include them in the testing strategy the right way. These are just some of the testing types our QA engineers excel in.

The success of a software project depends, among other things, on whether it’s the right fit for the industry it’s in. And that is true not just for the development stage, but also for QA. Different industry have different software requirements, and our team knows all about them.
