Software Testing Definition
Software testing definition can be stated as the technical process to recognise and ensure the accuracy, security, totality and quality of newly developed computer software. A software tester looks for the capability, efficiency, compatibility and usability of the software. The main aim of software testing is to provide the customers the maximum product quality. There are various procedures to explain Software testing definition:
? Performance testing: The main aim of this method of testing is to check the final performance of the software. The engineering and functional capabilities of the software are evaluated in this method.
? Compatibility testing: This is a non-functional test used to evaluate the compatibility of the software with the computer environment.
? Load testing: In this method, the program is loaded excessively and its response in such circumstances is observed. ? Recovery testing: This test checks the capability of the software to recover from hardware failures and crashes. ? Stress testing: This method is used to test the stability of a program. The program is loaded to its breaking point and the resources available to it are seized from it. It is then seen that how well the program can recover itself without the resources available. ? Installation testing: This test focuses on the installation process of the software. It may involve partial or full install/uninstall processes. ? Scalability testing: This test is a non-functional test used to measure the capability of the software to scale up or scale out. ? Maintenance testing: This test is performed to identify problems and the capability of the program to repair them. ? White box testing: In this method of testing, the structure of the software and its flow rate is clearly seen by the tester. It is also termed as Glass-box testing, Logic-driven testing or Design-based testing ? Sanity testing: This method aims at seeing whether the computer program is working according to the expectations or not. ? Usability testing: This main aim of this method is to measure how well the program can be used by its users. ? Ad-hoc testing: It is a test applied to a software program without planning and structure. It is usually run only once, unless a defect is discovered. ? Regression testing: This is another method in Software testing definition used to uncover regression bugs that occur when any functionality stops working or not work efficiently. ? Black box testing: In this method, the data is derived from functional necessities without affecting the structure of the program. It is also termed as input/output testing or data-driven testing. The main aim of this testing is to check the functionality of the program. Each software testing method has a different method of testing and is undergone with a different objective. They can look for errors, quality, safety, faultlessness, protection, potentiality, maintainability and other aspects of a software program. A software program is incomplete without proper testing. Software testing definition has some standards mentioned to it. Before testing a software program, a test plan is prepared which includes the tools to be used, various inputs and the expected results. Code review is also a part of software testing and is done by a programmer who has the basic knowledge about coding. Code review contains the comments before a code block begins and the proper arrangement of coding. A favourable code in a review of software testing definition will ensure that the software programme is easily maintainable.
