What is Software

Software is a set of instructions or programs that tell a computer what to do. It can be divided into two main categories ie., system software and application software.

System software includes the operating system and all the utilities that help keep the computer running. Application software includes programs that do specific tasks, such as word processing or playing games.

Other types of software, including: middleware, driver software, programming software.

What is Software Testing

Software testing is a process, to evaluate the functionality of a software application with an intent to find whether the developed software met the specified requirements or not and to identify the defects to ensure that the product is defect-free in order to produce a quality product.

Let’s see the standard definition, testing types such as manual testing and automation testing, testing methods, testing approaches, and types of black-box testing.

Some of the reasons why testing become a very significant and integral part of the field of information technology are as follows. These are the benefits of software testing.

  • Cost-effectiveness
  • Customer Satisfaction
  • Security
  • Product Quality


As a matter of fact, design defects can never be completely ruled out for any complex system. It is not because developers are careless but because the complexity of a system is intractable.

If the design issues go undetected, then it will become more difficult to trace back defects and rectify it. It will become more expensive to fix it.

Sometimes, while fixing one bug we may introduce another one in some other module unknowingly. If the bugs can be identified in the early stages of development, then it costs much less to fix them.

That is why it is important to find defects in the early stages of the software development life cycle.

One of the benefits of testing is cost-effectiveness.

It is better to start testing earlier and introduce it in every phase of the software development life cycle and regular testing is needed to ensure that the application is developed as per the requirement.

Customer Satisfaction

In any business, the ultimate goal is to give the best customer satisfaction. Yes, customer satisfaction is very important.

Software testing improves the user experience of an application and gives satisfaction to the customers. Happy customers mean more revenue for a business.


This is probably the most sensitive and vulnerable part of testing. Testing (penetration testing & security testing) helps in product security.

Hackers gain unauthorized access to data. These hackers steal user information and use it for their benefit. If your product is not secured, users won’t prefer your product. Users always look for trusted products. Testing helps in removing vulnerabilities in the product.

Product Quality

Software Testing is an art that helps in strengthening the market reputation of a company by delivering a quality product to the client as mentioned in the requirement specification documents.

Due to these reasons, software testing becomes a very significant and integral part of the Software Development process
