It is not a secret that software testing services means a lot in the software development life cycle. Yet another question is who the tester is and what methods he utilizes while carrying out quality assurance (QA) services. A faithful tester should not forget the below discussed purposes of Quality Assurance services in order to achieve positive result after performing testing. Let’s sort out the main purposes of QA services!
The main purpose of software testing services is verification. If you think that the main task a tester does is simply looking for bugs in the software, it is not always true. In reality, a QA measure that is implemented for verifying whether the software is working correctly and suggests an extensive status report in which the observation of factual attributes and functions of software is compared to the written requirements. Verification is necessary to conclude whether the developed software executes all the necessary conditions and corresponds to the announced release.
The next purpose is priority coverage. Because of the fact that every aspect of software development life cycle is impossible to test, it is essential to arrange priorities according to QA needs. In order to make sure that the software possesses a base line utility, every subset of it should be tested with genuine input cases. Then it is important to test invalid input and non-functional needs. Still under every circumstance, software must be tested with real issues cases, paying attention to more average cases then something special. With wise time management, you should set priorities to more frequent cases.
The next important purpose is unbiased tests. User expectations should coincide with the written requirements of the performed test. The tester should consider all written and unwritten specifications while fulfilling testing services. It is advisable that the tester takes an unprejudiced approach for a wide range of testing cases.
The last important purpose of the software testing services is applying deterministic approach that suggests that cases should be systematic and at the same time the coverage criteria should involve defects of all priority and nature. Defects, which appeared later should be mentioned as well and placed under the appropriate coverage sphere.
