Software Quality Assurance and Testing - Testing why it's needed

As the title mentioned, why do we need to test stuff when we do our projects? Is it necessary for the business to have this kind of department? Would it benefit the project to have testers?

I would like to give my insight here about the things that I learned so far from this course and the importance of Quality Assurance for Software Development Life Cycle (SDLC)

On the bigger picture, testing is just one aspect of Quality Assurance. It would seem that Quality Assurance has other things that also need to be considered such as compliance, legality, business validation etc. By history, there are several businesses where projects failed due to lack of testing and tons of money are at loss. This is where the development of Quality Assurance was born. And the standards for Quality Assurance are in accordance with ISTQB.

Testing can be a rigorous task as well just like other jobs. There are some key factors needed in order for testing to be successful. First, someone would have a keen eye for details firstly. Whether you doing testing manually or automated, you need to catch all the unusual things from the project that you're working on. Depending on the severity and priority, these must be communicated to your peers all the time.

 

I would go more into details about testing in my next post for Software QA and Testing
