• Expectations and success criteria must be defined to ensure clarity of the process.

• Unit testing:

• Test each small software unit separately using unit tests.
• This ensures that each module is working properly before being integrated with other modules.

• Automated testing :

• Use automation tools like Selenium, JUnit, or NUnit to execute tests periodically and automatically.
• This approach helps detect errors faster and improves overall process efficiency.

• Continuous integration testing :

• Perform integration tests regularly to verify that all software components are working interoperably.
• This helps detect any problems that may arise as a result of combining different components.

• Checking inputs and limits :

• Test software using a variety of inputs, including boundary cases and invalid data.
• This ensures that the software works properly under all conditions.

• Performance and load testing :

• Perform performance tests to evaluate system responsiveness under high stress using tools like Apache JMeter.
• This helps in understanding how well the system can handle large loads.

• Security Test :

• Perform security tests to ensure that the system is hack-resistant and provides adequate data protection.
• Potential security threats must be investigated and necessary measures implemented to ensure security.

• Test documentation :

• Be sure to document all quality tests performed, expected results, and any problems discovered.
• This log helps review processes and is a useful reference for improving the system.

• Continuous improvement :

• Use quality test results to develop and improve future processes.
• Listen to team and customer feedback and use it to improve product quality.

• Stability test :

• Perform stability tests to ensure that the system remains reliable under long and variable operating conditions.
• These tests include measuring memory usage and analyzing performance to ensure long-term system stability.

Applying these practices in quality testing contributes to achieving the highest levels of performance and quality of the final product. They should be adapted to the needs of the project to ensure overall success.

How to implement security testing in the software engineering process

Through the following, we will review a general model for implementing security tests in the software engineering process:

• Risk Analysis and Test Design : Analyze the potential risks of the software system and identify potential weak points and potential security vulnerabilities. Based on this analysis, design appropriate security tests to test for those weak points and security vulnerabilities.
• Authentication and Authorization Testing: Perform tests to ensure that authentication and authorization are working properly, validate login and authorization processes, process permissions, test user identity confirmation, and log activities.
• Test for invalid entries: Perform tests to verify how the system handles invalid or suspicious entries and enter incorrect or unexpected data and verify the system's response and ensure that it handles them securely without exposing security vulnerabilities.
• Penetration Testing : Perform tests to test the strength and resistance of the software system to penetration. These tests can include ethical penetration tests, simulated penetration attacks, and hit tests. These tests aim to discover potential security vulnerabilities and fix them before they are exploited by real attackers.
• Fraud Protection Testing : Run tests to verify how the system handles potential fraud attempts. Test known and suspected fraud attacks and verify the system's ability to detect, prevent and log them.
• Denial of Service Attack Testing : Perform tests to assess the system's ability to handle Denial of Service attacks, experiment with a high load of requests and attempt to flood the system, and verify that the system responds appropriately and is able to resist such attacks.
• Encryption and Security Testing : Perform tests to verify that the encryption and security mechanisms used in the system are working properly, verify that appropriate encryption protocols are used, and verify that data sent and stored is properly encrypted and protected from unauthorized access.
• Update testing and bug management : Perform tests to verify how the system handles update processes and manages known security bugs. Verify that the system is able to download and install security updates on a regular basis and that bugs are managed effectively and fixed in a timely manner.
• Test rules and policies : Perform tests to verify that the system adheres to applicable security rules and policies and verify that appropriate rules are applied for each aspect of security, such as password, approval, storage, and access rules.
• Review guidelines and instructions : Review the security guidelines and instructions used in the software engineering process and ensure that they are reliable and up-to-date. These guidelines should outline the steps required to implement security and the recommended security practices for the development team.

These steps should be performed frequently and regularly throughout the software engineering process to ensure that the software system is well protected and responsive to potential security threats. You may need to incorporate security testing into the ongoing development process, such as adopting automated testing, static analysis of source code, and continuous security auditing.
