Software testing is the process of evaluating and verifying that a software product or application does what it is supposed to do. The benefits of testing include preventing bugs, reducing development costs and improving performance.

When testing banking applications, it is very important to ensure that they meet the highest standards of security, functionality and reliability. Banking applications handle sensitive user data and financial transactions, so thorough testing is essential to ensure a smooth and secure user experience.
Functional testing: This is the testing of the core functionality of the application such as account registration, login, balance inquiry, fund transfer, bill payment, transaction history. Testers need to ensure that these functions work as intended and handle various scenarios, including errors.
Security Testing: Given the sensitive nature of banking applications, security testing is of paramount importance. Testers should focus on aspects such as data encryption, secure communication protocols (e.g. HTTPS), secure storage of user credentials, protection against common vulnerabilities (such as cross-site scripting and SQL injection), and compliance with regulatory requirements (e.g. PCI DSS), it's all written about at https://testfort.com/blog/how-to-test-banking-applications-complete-guide . Regular testing, as well as ongoing monitoring and user feedback, will help identify and remediate any issues, ensuring your banking applications run reliably and smoothly.
