Software Testing Questions

Software testing is verifying if a software meets the customer's requirements; if it has high quality; if it is bug free and if it is fit for use. Testing is important because it ensures that the product delivered is defect free which in turn emphasizes higher quality and proves to be cost effective.

Quality Assurance Manager (QA Manager) defines the process to be followed at each phase of SDLC. He defines the standards to be followed, the documents to be maintained and sets the standard for the product.

Where as it is the Project Manager’s responsibility to ensure that the things defined by QA manager are being implemented. He develops the product from start to finish with his team and ensures that the product which is to be rolled out is Defect free and it reaches the standards and views defined by QA Manager.

QA managers can audit the process for certain time periods which are being handled by the Project Manager.

Integration testing is done at module level when various modules are integrated with each other to form a system or sub-system. Its main purpose is to ensure that interfaces between various modules are working properly; i.e. modules which are working individually are also working correctly together.

System testing is done on a complete, integrated system to evaluate the system’s compliance with its specified requirements. It validates that the system meets its functional and non-functional requirements.

From these definitions, it is clear that the purpose of Integration and purpose of System Testing are different. Therefore, Integration test cases focus more on the interfaces between modules (interface integrity) - the data transfer and their interaction with each other. System test cases focus on testing the product as a whole; i.e. whether the functional, non-functional requirements of the System are met or not. Since System Testing is the final phase before delivery of the product, System test cases should pinpoint configuration related errors along with testing for performance, security, reliability etc.

The parameters of Quality Cost are:

Speed
Accuracy
Efficiency
Performance
Customer Satisfaction

Configuration Management is a support for software in managing the different items in the product, and changes in them.
