Q1.Forward engineering is not necessary if an existing software product is producing the correct output. Is the statement true or not. Justify with your answer.

Answer:

No, It’s not true. As Forward Engineering is a method of creating or making an application with the help of the given requirements. Forward engineering is also known as Renovation and Reclamation. Forward engineering is a technique of creating high-level models or designs to make in complexities and low-level information. Therefore this kind of engineering has completely different principles in numerous package and information processes. Forward Engineering applies of all the software engineering process which contains SDLC to recreate associate existing application. It is near to full fill new needs of the users into re-engineering. Forward engineering deals with the conversion of business processes, services, and functions into applications. In this method business model is developed first. Then, a top-to-down approach is followed to urge the package from the model developed.

Q2.List and explain different types of testing done during the testing phase.

Answer:

Accessibility Testing

Accessibility testing is the practice of ensuring your mobile and web apps are working and usable for users without and with disabilities such as vision impairment, hearing disabilities, and other physical or cognitive conditions.

Acceptance Testing

Acceptance testing ensures that the end-user (customers) can achieve the goals set in the business requirements, which determines whether the software is acceptable for delivery or not. It is also known as user acceptance testing (UAT).

Black Box Testing

Black box testing involves testing against a system where the code and paths are invisible.

End to End Testing

End to end testing is a technique that tests the application’s workflow from beginning to end to make sure everything functions as expected.

Functional Testing

Functional testing checks an application, website, or system to ensure it’s doing exactly what it’s supposed to be doing.

Interactive Testing

Also known as manual testing, interactive testing enables testers to create and facilitate manual tests for those who do not use automation and collect results from external tests.

Integration Testing

Integration testing ensures that an entire, integrated system meets a set of requirements. It is performed in an integrated hardware and software environment to ensure that the entire system functions properly.
