Integration Testing

It is important to test that Apache Fineract integrates seamlessly with other systems and third-party services like payment gateways, SMS gateways, and mobile apps. Know about integration testing vs. end-to-end testing.

• Testing the integration with payment gateways to ensure transactions are processed securely and accurately.
• Verifying the integration with mobile banking apps, ensuring that data flows correctly between the app and Fineract backend.

Supporting Tools

• Apache JMeter: Useful for both load testing and integration testing, JMeter can simulate a heavy load on a network or object to test its strength or to analyze overall performance under different load types.
• SoapUI: Though more focused on SOAP web services, SoapUI can also be used for RESTful API testing and is useful for testing Fineract’s web services integration capabilities.

Performance Testing

To evaluate the system’s performance under various conditions and workloads to ensure it can handle expected and peak loads.

• Simulating thousands of concurrent users to test system behavior and response times during high traffic.
• Load testing the database operations ensures the system can handle large volumes of transactions without degradation in performance.

Supporting Tools

• Apache JMeter: Apart from integration testing, JMeter is excellent for performance testing, capable of simulating multiple users with concurrent requests to test the scalability and performance of web applications.
• Gatling: It is an open-source load testing tool designed for analyzing and measuring the performance of services. Gatling can be used for stress testing Fineract, especially its RESTful APIs.

Security Testing

It is required to identify vulnerabilities within the system and ensure that data is protected against unauthorized access.

• Conducting penetration testing to uncover security weaknesses.
• Testing for SQL injection, cross-site scripting (XSS), and other common security threats.

Supporting Tools

• OWASP ZAP (Zed Attack Proxy): It is an open-source web application security scanner. ZAP is excellent for finding vulnerabilities in web applications, including those built with Apache Fineract.
• Fortify: Offers comprehensive static and dynamic security testing of software code. It helps identify security vulnerabilities in the Fineract platform.

Usability Testing

It is required to check that the application is user-friendly and aligns with the needs of its target users, including administrators, financial officers, and end-users.

• Gathering feedback from a group of microfinance institution (MFI) workers. One case is feedback about the ease of use of loan management features.
• Testing the mobile app interface with actual users to evaluate navigational ease and clarity of information.

Supporting Tools

• UserTesting: Provides real-time feedback from users, which can be invaluable for usability testing of Fineract’s user interfaces and overall user experience.
• Lookback: Offers a set of tools for conducting live or recorded user testing sessions. It provides insights into how real users interact with your application.

Regression Testing

Verifies that new code changes and bug fixes do not adversely affect existing functionalities.

• Running the entire test suite after updates are made to the loan or savings module to ensure that existing functionalities are not broken.

Supporting Tools

• Selenium: For automating web browsers, Selenium can also be effectively used for regression testing. It helps in ensuring that new changes do not break existing functionality. However, here are 11 reasons why not to use Selenium because better tools are available. We will see that in the next section.
• TestNG: A testing framework designed to cover all categories of tests: unit, functional, end-to-end, integration, etc., making it suitable for regression testing.

Compliance Testing

Compliance testing is more about adherence to standards and regulations than specific tools. However, organizations and products like Qualys and Nessus provide security and compliance solutions. They can help identify vulnerabilities and ensure systems comply with specific security standards.

Role of AI and Test Automation

Considering the complexity and the services that are being provided by Apache Fineract, the number of test cases is quite huge. For example, a banking project’s typical code coverage for lending or deposit modules has 10,000 to 20,000 test cases. This is just one module, and a banking project has multiple complex modules. To attain great test coverage, automation testing is a must, that too with testing tools supporting parallel testing.

Firstly, the financial application is complex, and then creating test scripts for this application with good code coverage in a programming language is daunting. Here, you need support from intelligent automation testing tools such as testRigor. It allows you to write test cases in plain English through generative AI. Also, it does not use flaky CSS/XPath locators. It uses a unique and easy way to identify elements on UI. Just mention the text as you see on the screen to identify any element.

login
click "My accounts"
click on exactly "More"
wait 3 sec
click "profile"
click "payment method"
verify page contains "payment method"
verify page contains "visa" or "amex"
verify page contains "add payment method"

You can see how simple writing test cases is for even a complex module. testRigor makes it simple for everyone in your team to contribute to testing activities irrespective of their programming skills. Here are a few features which will help you in testing Apache Fineract applications with testRigor:
