How to Test Banking Apps on Real iOS & Android Devices?

Mobile bank application testing ensures banking apps are secure, reliable, and user-friendly. It protects sensitive financial data from cyber threats while maintaining seamless functionality across devices.

This article covers why banking apps need testing, key benefits, essential testing types, sample test cases, and how to test on real iOS & Android devices.

Importance of Mobile Banking Application Testing

Inadequate testing of banking apps can lead to serious consequences, affecting both users and financial institutions.

• Security Breaches: Weak security in an app allows cybercriminals to access sensitive information easily, which can lead to fraud and financial losses.
• Regulatory Violations: If your app doesn’t comply with financial regulations, you could face fines, lawsuits, or even lose your banking license.
• Poor User Experience: Slow app performance, crashes, or confusing UI can frustrate customers. Such errors can push your customers to competitors.
• Transaction Failures: Bugs in a banking app can cause incorrect payments, double charges, or even lost funds, which can create chaos for customers.
• System Downtime: If your app isn’t stable, it could go down during peak hours. It can disrupt banking transactions and damage your reputation.
• Data Corruption: Errors in database transactions can lead to incorrect balances, lost records, and financial mismatches.

Banking apps, or BFSI apps in general, are crucial and sensitive. They contain almost every detail about their customers, from personal to financial status. To protect from cyberattacks, such apps must be highly secure while providing smooth performance for the end user’s experience.

Benefits of Banking App Testing

By testing banking apps, you ensure security, reliability, and compliance. It helps to deliver a smooth user experience while preventing costly errors and security breaches. Some primary benefits include:

Improving Complex Systems

Banking applications cover crucial financial touchpoints, and it can be challenging for developers to manage everything so complex in one application. By testing the banking apps, testers can eliminate  bugs and enhance the overall SDLC of complex app architecture.

Streamline User Experience

Considering the digitalization of banks and user dependency on digital processes, banking apps must have a functional UI. It should be easy to complete tasks like transactions, checking balances, applying for a credit card, etc., without any interference or glitches. QA testers should be testing each feature thoroughly to achieve this.

Protect Sensitive Data

Banking apps are soft targets for cyberattacks targeted on the user database. Through testing QA testers can identify & resolve bugs, loopholes, or threats in the application that hackers can take advantage of. Testing here ensures security and user database protection.

Improve App Performance

BFSI apps demand high performance, a smooth interface experience, and transaction security. And that can only be achieved by eliminating bugs & glitches in the application. Testing the banking apps on real devices highlights such glitches and fixes that is encountered only while testing under real user conditions.

Ensure Smooth Feature Updates

Banking apps require continuous changes and new feature updates for new services being rolled out.  Regression testing here plays a crucial role in ensuring a smooth release velocity. With parallel execution, you get test feedback in minutes. That way you can distribute your regression tests across hundreds of parallels and run them all at once.

Types of Testing required for Banking Apps

Here are the essential tests to include when testing a mobile banking app:

1. Functional Testing

It is a basic testing parameter QA testers examine all the functionalities of the banking application and ensure all added features function properly. Also, it brings forth any bugs/errors that might require resolution.

For example, users shouldn’t have to click more than twice or thrice to transfer money or get their monthly statement successfully. The app should be intuitive, easy to navigate, and self-explanatory.

2. Security Testing

Impeccable security is the top priority for BFSI apps. Cyberattackers target banking applications for user databases and transaction history.

3. UI Testing

Banking applications must be user-friendly delivering a smooth performance so that users can complete transactions, check balances, and do other financial work easily without any hiccup. Most banking applications require a user-friendly interface, simple UI, and clear CTA that makes the performance faster.

4. Performance Testing

Speed is an important factor for any application, especially in banking, as customers need a quick resolution of queries. So the banking app must perform fast and complete all the actions like checking balance, transactions, request for documents, etc in minimal time. Otherwise, it will create a bad user experience prompting them to uninstall the app.

5. Chatbot Testing

In BFSI apps, chatbot testing ensures seamless self-service and secure user interactions. It verifies response accuracy, security, and integration with banking systems, enhancing customer engagement and operational efficiency.

Sample Test Cases for a Banking Application

QA testers when testing a banking application are required to test the same as an end user. Here are some common mobile app test cases that needs to be verified:

• Test if customers can easily log in to their account via id/pass, or if they forget credentials, the restoration process must be hassle-free.
• Verify whether users can complete transactions securely via card detail or bank account transfer.
• Test if users can check their available balance for multiple accounts.
• Verify security features, like whether the banking application blocks the account after three wrong attempts.
• Try creating a new account with the wrong credentials and see if the banking application accepts it or not.
• Check if data updations are reflected in the database.
• Test if a user gets any notifications from the bank about transactions like alerts, debit, credit, etc.

When writing test cases for banking apps, it is essential to run these tests on real devices. While this is important for apps in any domain, it is especially crucial for banking apps.
