Question

Software Testing

Write a description of what “software quality” means. Is there a simple definition for what quality software is? What attributes make up “quality”? Is quality truly important for the success of software products? How does testing contribute to a quality product?

Answer 1

Software quality is the totality of functionality and features of a software product that bear on its ability to satisfy stated or implied needs.To better understand software quality, it is useful to focus on three groups of people who develop software quality during and after this process: the software users, the development team, and the sponsors of project. Everyone involved in a software project cares most about the aspects of quality that most impact them.

Software quality includes three components:

1.functional quality

2.structural quality

3.process quality

1.Functional quality means that the software correctly performs the tasks it is meant to do for its users. The following are aspects of functional quality:

Meets the specified requirements for the software:

it has Has few defects , performs well and it Is easy to learn and use.Software testing commonly focuses on functional quality.

These are aspects of structural quality:

1.Code testability

2.Code maintainability

3.Code understandability

4.Code efficiency

5.Code security

These structural aspects have a big impact on how quickly new developers can start working with a code base. Unlike functional quality, structural quality can be hard to test for.

Process quality is also critically important. The aspects of process quality include:

1.Meeting the delivery dates

2.Meeting the budget

3.Having a repeatable development process that reliably delivers software quality

There are many definitions for quality software we can tell it as "Quality software is reasonably bug or defect free, delivered on time and within budget, meets requirements and/or expectations, and is maintainable."

QUALITY ATTRIBUTES:

1. Performance

2. Security

3. Modifiability

4. Reliability

5. Usability

6. Availability

7. Throughput

8. Configurability

9. Reusability

- Yes software quality plays major role for the success of the software product as no one wants to use the software which is not a good quality. And if has lags or crashes in it users will just remove that from their devices so a software with good quality will performs better in all the aspects

Software testing:

Software testing is a series of processes that investigate and evaluate the quality of software. It ensures that software product is building by regulatory, technical, business, functional and user requirements.

Software testing is a wide process that includes several connected processes. Three things you check through these processes: software completeness regarding functional requirements; finding technical errors and ensuring the software is bug-free; assessing usability, performance, security, localisation, compatibility, and installation.

Testing contributes to software quality in many ways some of them are

In software development, everything needs to double-check before releasing the product. It is important to have a tester team who will test software and invest effort and knowledge to make sure that product is defect-free.

Software testing will point out the errors that occur during the development phases. It makes sure that the application’s performances are adequate and that customers are satisfied with it. When the delivered product is of quality, it helps in gaining the confidence of the customers.

Software testing with strict test execution assures lower maintenance cost. There cannot be any failures because it can be very expensive in the later stages of the development.

For staying in business, having a software testing is imperative. A critical defect left undetected can cause losses in business. Every serious company will invest in a tester team and find experts who will be capable of detecting problems and flaws in a software product.
