WHAT IS SOFTWARE TESTING?

• The act of confirming and verifying whether software is bug free can be referred to as software testing. In order to provide greater   precision, it primarily tries to measure the functionality and   performance of software.

TYPES OF SOFTWARE TESTING:

1.Manual Testing:

• Testing software by hand, without the aid of an automation tool, is referred to as manual testing.The end-user typically performs this to see if the software contains any bugs  There are various different kinds of manual testing including acceptance,integration, and unit tests.

2. Automated testing: 

• In this case, the end-user often makes use of the software tools to validate the specific software. Generally speaking, it is superior to manual testing.
• Software's separate components are examined during unit testing. The goal is to confirm if each piece of software works as intended or not and whether it can move on to the next round of testing or not.

LEVELS OF SOFTWARE TESTING:

1.Unit testing: 

• In this step, the software's constituent parts are examined. The goal is to confirm if each piece of software works as intended or not and whether it can move on to the next round of testing or not.

2. Integration Testing:

•  In this step, the separate elements are brought together as a group.

Finding the flaws is the major goal of this examination.

3. System testing:

•  All aspects of the software integration are tested here. Checking the software's components to their requirements is the key goal.

4.Acceptance Testing: 

• In this step, the acceptability of the combined components is examined. Here, delivery to the end user and verification are the major goals.

PRO’S OF SOFTWARE TESTING:

The following are advantages of employing software testing:

1. COST-EFFICIENT: 

• Software testing has a number of advantages, including being affordable. Any IT project can save you money in the long run if testing is done in a timely manner. Fixing faults is less expensive if they are discovered earlier in the software testing process.

2. Security: 

• Software testing's risky and delicate benefit. People are looking for trustworthy products. It helps to eliminate risks and problems earlier.

3. Customer satisfaction: 

• Providing clients with contentment is the main objective of every product.
• Early investment in quality assurance shows your clients that you are concerned about their experience. You want them to achieve all of their goals and more. And establishing long-term consumer connections depends on this message.

         4.IMPROVES PRODUCT QUALITY:

• Even though businesses may be aware of the advantages of Software-as-a-Service (SaaS), they won't invest if the service is of poor quality. They need to satisfy their clients just as much as you do, after all.

         5.ENHANCES DEVELOPMENT PRODUCT:

•  You can find a wide variety of scenarios and errors, for the reproduction of the fault, with the help of quality assurance.
• It is really straightforward, and the developers must quickly correct it. Software testers should work alongside the development team concurrently as well, as this helps to speed up the development process.

WHY SOFTWARE TESTING IS NECESSARY?

1. To GAIN CUSTOMER CONFIDENCE:

• The user-friendliness of the software is ensured by testing. As a result, the customers for whom it is meant can use it. 
• Customer’s need are known to those who specialise in software application testing, and unless a programme can meet those needs, it would be a practically pointless investment.

2.TO CHECK SOFTWARE ADAPTABILITY:

•       If the functionality of software is affected by the change of devices, it can count towards a negative user experience. Testing eliminates such errors in the performance while adding to the compatibility and adaptability of the software.

3.TO IDENTIFY ERRORS:

•       Even a single bug can be damaging for the reputation of a software developing house. It can take a long time to regain customer confidence, so it’s much better and ultimately more convenient to ensure testing is being achieved.

4.TO ACCELERATE SOFTWARE DEVELOPMENT:

•       Some companies also neglect software testing as they have spent too much time on the software development process, and need to quickly deliver the product to the client. While this may be a problem with time-management in how a software development team is considering its work delegations, it’s also an issue of conceptualizing software testing.

SOFTWARE TESTING PRACTICES:

• Software testing uses a standard procedure. Determining the test environment, creating test cases, writing scripts, examining test results, and sending defect reports are tasks or steps.
• Testing might take a lot of time. For tiny builds, manual or impromptu testing may be sufficient. However, technologies are commonly employed to automate operations for larger systems. Teams may test alternative scenarios, differentiators (such shifting components into a cloud environment), and quickly receive feedback on what works and what doesn't with the aid of automated testing.

WHY SOFTWARE RECOGNISED FOR FUTURE USE?

• The relevance of software testing should be recognized because it is a very broad and vast issue that is regarded as an essential and crucial component of software development .With the aid of software testing, you will be capable of verifying each and every aspect of software testing .For instance, with the aid of software testing , it is possible to monitor whether the software is compatible with your browser .Thus, in case, you gain success in finding any error, you will be having the option for the rectification of the same .Thus, you will be capable of saving from the complaints and you will gain a high prominence slowly but gradually.
