Today, it is very rare that a bank does not have an online presence; all banks have various mobile and web applications to help their customers view account balance online, do transactions, pay utility bills, and access many other services.
To stay competitive in the market, to gain customer satisfaction, designing, and providing error-free, user-friendly application is crucial. To achieve this, the testing team plays a vital role during the development process; they need to test the system with the utmost caution.
This article discusses some of the best practices that organizations can follow while testing complex banking applications.
Early Involvement of the Testing Team
One of the good practices is to include the testing team in the requirements analysis phase; it will help them in preparing for the test planning and understand the requirements clearly.
Testers think from the end-users perspectives and can help in analyzing the requirements; they can also help in identifying missing requirements. Moreover, once the requirements specification is ready, testers can review them and suggest the changes. In agile projects, testers can help in user story creation.
Clear and Detailed Testing Plan
Once the requirements are ready, the next step for the testing team is to create a test plan. Banking application projects are like any other projects, but as such applications deal with sensitive data and money transactions, it is very critical to manage the testing process.
The testing process for such applications tends to take more time and is a bit difficult as it deals with multiple complex features. Thus, it is important to prepare an exhaustive testing plan and strategy with all the required details. It is also a good idea for any project to find critical bugs as soon as possible so that the development team can start solving them, and it eventually doesn’t affect the overall project timeline.
Familiarity With the Domain
For every tester involved in the testing of a banking application, ideally, it should be a mandatory requirement to have domain knowledge of the banking sector. With the domain knowledge, testers will be able to design more in-depth test scenarios, and also while testing the system they can think out of the box and find as many defects as possible.
Moreover, the knowledgeable testing team gives client satisfaction regarding the efficiency and effectiveness of the testing process.
Usage of Automation Tools
Like any other application testing, it is always a good idea to use automation tools whenever possible in the maximum productive manner. As banking applications have complex features, multiple users logging in the system at the same time, and doing multiple transactions, and taking multiple actions, the testing team can take the help of the automation testing tools to speed up the process, and effectively test the system. Some of the popular automation tools to test such applications are Selenium, QTP, HPWebInspect, IBM App Scan.
Vast and Real Test Data
Another good practice is to prepare real production-like data and mimic the real scenarios. A real live application will have thousands to millions of users, each user will be availing multiple services, so it is also important to create test data with a huge number of users and other related details.
Usually, getting hold of the production like data is not always possible; and a lack of thorough testing without such data may result in errors in the real-world application e.g. some customer has billions of dollars in his account or he transfers a high number of amount in one transaction and another customer has a couple of hundreds or thousands in his accounts and transfers in hundreds and thousands; the testing team needs to test with both the scenarios and check for a smooth transfer of money along with proper UI.
Only Functional Testing Is Not Enough
Testing complex banking applications require extra care and focus on other testing types such as database testing, security testing, performance testing. Functional testing checks whether the features have been implemented as per the requirements or not, but this is not enough. The team needs to test the database of the application for its integrity, validity, and updates.
The testing team should have in-depth knowledge of SQL queries, stored procedures, and other database tools. Another important testing is security testing; in this testing, the team should ensure that the application has proper mechanisms in place to handle data breaches, to manage authentication and authorization of users, etc. In performance testing, the team should make sure that the application can handle multiple users and their actions simultaneously.
Testing any application that deals with money-related transactions and various regulations is a difficult task and the testing team needs to make sure they test such applications as thoroughly as possible. By following above mentioned and many other best practices, the testing teams can help in delivering high-quality secure applications that provide maximum ease of use and increased user experience.
