Why Software Testing is Important for Business

 

Software testing is a kind of method which detects whether software that is developed meets expect requirements and software developed is bug-free.

It involves many things like software testing which includes system components, manual or automated tools, devices to test the software, and many other properties.

Software testing means the verification and validation of the software application under test (AUT).

Why is software testing important?

Software testing is important because there are many bugs and glitches in the design and development of software that can be identified early and fixed before the software goes live.

A validated tested software product ensures its reliability, security, and high performance which further results in time-saving, cost-effectiveness, and customer satisfaction.

Software bugs are much more important and need to be fixed as soon as they appear, hiring a  software tester will save your time and will provide the best as a software product.

Here are some of the incidents which have cost big companies, and gives and sets an example, why software testing is important.

● · In the US, MAY 1996 a small software bug caused the banking system to affect customers' accounts, resulting in millions of dollars.

● Pentium, one of the biggest manufacturers of chips, which are called the brains of any operating system, caused errors in calculating the correct value of a number after 4 or 5 decimal points in1994 called the FDIV bug.

● Amazon, the highest e-commerce retailer, was also affected as one of the retailer saw a 1% drop in his product price due to a software glitch in amazon which created a heavy loss for him and amazon had to settle the account.

●  A malfunction in a radiation therapy machine in a Canadian hospital caused the life of a person and several were injured in 1985.

● A software glitch in the POS system forces Starbucks to close their retail stores in the US and Canada with 60% of operations

● Nissan, one of the biggest manufacturers of cars, faced issues in 2013-14 models where the front passenger-side airbag may deploy in a crash, explaining the national highway traffic safety administration where the software problem was according to the operating system.

● The US biggest prison break was caused due to a software glitch in December 2015, where 3200 prisoners were released before their announced date. The software was developed to track every prisoner's activities in 2002 where every inmate was released early.

● Yahoo, one of the biggest search engines, was affected in September 2016, there was a breach of data costing one of the biggest credential leaks.

● HSBC, one of the biggest banking sectors, faced the same issues, where millions of customers were not able to log in and the bank took two days to resolve the software bugs.

●  February 16, 2020, London Hathway Airport was affected by a technical glitch that affected department boards and check-in systems, leaving passengers with little information.

 What are the benefits of software testing before launch?

Let's see some of the benefits of software testing which are done before any software application launch.

• Economical: Before deploying any software web application it is beneficial as it helps to save time for the long term, In the case of bugs that get detected in the early stage of development.

• Security: People are looking for trusted products and it is liable and reactive to do software testing.

• Quality: It is very important for any software application which ensures that the best product is being delivered to the users.

• Satisfaction: While testing UI/UX it provides the best user experience which should be the main focus of any agency.

What are the types of software testing? 

The software testing has been classified into three different parts that provide information on how it is performed and make changes in products.

❖ Functional  Testing

❖ Non- Functional Testing ( Performance Testing)

❖ Maintenance

 

Functional Testing	Non-Functional Testing (Performance Testing)	Maintenance
● Unit Testing ● Smoke Testing ● Sanity Testing ● Integrated Testing ● White Box Testing ● Black Box Testing ● User Acceptance Testing ● Regression Testing	● Performance Testing ● Load Testing ● Volume Testing ● Stress Testing ● Security Testing ● Installation Testing ● Penetration Testing ● Compatibility Testing	● Corrective Maintenance ● Adaptive Maintenance ● Perfective Maintenance ● Preventive Maintenance

This is just a brief information on software testing for application or a product, it all depends on the type of business and its prospective for the users. 

What should be the testing strategy of a software tester? 

Here we are sharing some of the important factors, which a software tester should follow, which is a basic requirement of any software in testing it. 

Unit Testing : Software tester approaches a unit of code and runs a test, which helps software developers to identify if there is a bug or code is running perfectly fine. 

Integration Testing : These unit testing is done to know if the software architecture and design is running with any errors or not. 

System Testing : Software is tested with the full capacity which include it’s functionality, security, portability including other tests also. 

Programming Testing : In this method actual testing is done with the aim and notice of the behavior of the functions which are built in software for finding bugs, the test case is run and find analysis software response towards the testing. 

Quality testing is always considered when there are high chances to find the bugs and errors in executing any software and its functionality.  

Conclusion :  We have always seen that it is a tug of war between software developers and software testers regarding testing a software or application but it is mandatory to test before its release or making it live on the web. This gives a good impression about the company and products which they develop.
