Unit 4 Software Testing Pdf Software Testing Scalability Software testing technique: fundamental principal of testing: a 1. the goal of testing is to find defects before customers find them out. exhaustive testing is not possible; program testing can only show the presence of defects, never their absence. Unit 4 software testing: software testing is a process of identifying the correctness of software by considering its all attributes (reliability, scalability, portability, re usability, usability) and evaluating the execution of software components to find the software bugs or errors or defects. According to nielsen, usability can be defined in terms of five factors, i. efficiency of use, learn ability, memory ability, errors safety, and satisfaction. according to him, the usability of a product will be good and the system is usable if it possesses the above factors. The document outlines the importance and fundamentals of web application testing, emphasizing the need for rigorous testing to ensure functionality, usability, performance, security, and compatibility.

Software testing specialists help develop the test plan and evaluate the quality of software components. their role is to detect major software flaws (e.g. bugs, errors, failures, breakdowns, risks) in order to fix them and ensure the performance of the developed systems. Unit testing verifies the functioning in isolation of software elements that are separately testable. depending on the context, these could be the individual subprograms or a larger component made of highly cohesive units. Usability testing is a technique to explore the usability issues of a software product using prototypes and necessary documentation with appropriate users [5], [7]. the purpose of usability testing is to find the design issues and correct those issues. the functionality of the system is not required to perform the usability testing. At finding measures to improve the software in terms of efficiency, accuracy, and usability. it. program or application. 1. verification: it refers to the set of tasks that ensure that software correctly implements a. specific function. 2. validation: it refers to a different set of tasks that ensure that the software that has been built.
