Aim of Software Testing – IT Services

Before software is sold or delivered to the customer is it tested for its workability and quality. Moreover, software testing aims and evaluates the capability of a program or system and determines that the software meets its required results. Notwithstanding, software testing is crucial to software quality and is widely deployed by programmers and testers, it still remains an art for the reason that there is little or limited understanding of the principles of software testing.

However, software testing cannot be confined to debugging as the whole purpose of testing can be quality assurance, verification and validation, or reliability estimation of the software. Various difficulties arising out of software testing are such that there cannot be complete test of a program with moderate complexity.  Therefore, testing can be used as a generic metric which can test the correctness and reliability of the software.

Considered as a trade-off between budget, time and quality, software testing is done by almost all major software development companies. Software testing can be very costly and for that the automation is the best possible solution. Automation is an excellent way to cut down time and cost by using software testing tools and techniques which usually suffer from a lack of generic applicability and scalability. Saving on the cost, automation of software testing is an attractive solution.

Good software testing involves much more than just running the program a few times to see whether it works or not and ensuring that there is smooth working. There are two kinds of software testing e.g. white box and black box testing. The two are used by a test engineer when he designs the test cases. Whereas black box is used for external view of the test object, white box is used for internal view. Notwithstanding, software testing is partly intuitive, but largely systematic.

Aim of Software Testing

Software testing aims to identify the correctness, completeness, security, and quality of developed computer software. And, the whole process of quality test contains the process of technical investigation, performed on behalf of stakeholders, that is intended to reveal quality-related information about the product with respect to the context in which it is intended to operate. However, the quality is not an absolute; it is value to some person.

Software testing also includes testing the process of executing a program or application with the intent of finding errors. However, there cannot be complete testing of software as there can never be complete establishment of the correctness of arbitrary computer software. At the most software testing can furnish a criticism or comparison that compares the state and behavior of the product against a specification.

The observable fact is that using software testing to locate and correct software defects can be an endless process and can be considered a problematic method towards better quality. Moreover, bugs cannot be completely ruled out and chances are that testing and fixing problems may not necessarily improve the quality and reliability of the software as evidence show sometimes fixing a problem introduced much more severe problems into the system.
