What is Software Testing

Software testing is the process of checking the quality, functionality, and performance of a software product before launching. To do software testing, testers either interact with the software manually or execute test scripts to find bugs and errors, ensuring that the software works as expected. Software testing is also done to see if business logic is fulfilled, or if there are any missing gaps in requirements that need immediate tackles. 

 Why is Software Testing Important?

The road of software development is bumpy, and products can always be vulnerable to bugs and defects. It is necessary to ensure that software works as expected before being released to the market. Here are several reasons why software testing is essential:

1. Detecting defects for the development team to address

The end goal of software testing is always to uncover bugs and defects. Modern software is built from highly interconnected components that must work together seamlessly to deliver the intended functionality. One broken component can create a ripple effect and break the entire app. The sooner the broken code is fixed, the smaller the impact. A good testing process in place ensures that a higher quality and more reliable product is always delivered on time.

2. Maintain and enhance product quality

Product quality is more than just the absence of bugs. When we think of quality, we think of the characteristics that not only meet but also exceed customer expectations. An application is expected to perform the functions it was intended for, but it can only achieve the status of “high-quality” when it goes above and beyond those expectations. From this perspective, software testing is the key to quality, for the following reasons:

Maintain :

Regression testing to ensure that the quality is always kept at a consistent standard after adding new code

Periodic usability, compatibility, and security testing to ensure that these aspects of the software are kept well under check

Provide insights on product quality for the dev team to continuously update documentation.

Enhance :

Identify and address bugs to make the software more reliable

Identify areas for optimization and improvement

Ensure that software functionality work as expected

Ensure that the software aligns with user feedback

Ensure software compatibility across platforms and environments.

Benefits of Software Testing

1. Customer Satisfaction

The prime goal of any service-based organization is to serve the best features and experience to their customers, customer satisfaction is the only goal for the success and popularity of an application. 

Software testing helps in building the trust and satisfaction of the customer by assuring a defect-free application.

UI testing enhances customer satisfaction. Software Testing tries to uncover all possible defects and test an application as per customer requirements. 

For example, E-Commerce is dependent on the customer, and a satisfied customer will improve its market value and earnings.

2. Cost Effective

If an application works without any fault and with low maintenance will save a big amount for the owner. 

Software testing helps in early defect detection and fixing them to make a more successful and good return application. 

Every application demands maintenance and the application owner spends a good amount to maintain the working and functionality of the application. 

By testing an application, the maintenance area reduces too many folds and hence saves money.

3. Quality Product

The main focus of software testing is to deliver a quality product to its clients which results in a satisfied client. The quality of a product can only be maintained when it is bug-free and meet all the user requirements. 

4. Low Failure

Failure of an application impacts its working and brand value. Software testing helps in knowing the cases where a particular application is most likely to fail. 

5. Bug-Free Application

The main task of software testing is to identify bugs and inform them the concerned developing team to fix. When a bug is fixed, testers recheck the bug to identify its status.

100% bug-free application is practically not possible but the testing team tries to identify as many as possible bugs in the application by creating test scenarios. Software testing follows the STLC process to detect a bug. 

6. Security

The main concern of the digital world is Security. A secure system always remains on the priority list of customers. Owners pay multiple dollars to make their systems secure from hackers, malicious attacks, and other thefts. Security testing technique is used to identify the security level of the application and testers try to find loopholes to break the security of an application.
