Introduction to Software Testing
- 1. BIRLA INSTITUTE OF TECHNOLOGY MESRA, JAIPUR CAMPUS TOPIC : INTRODUCTION TO SOFTWARE TESTING BY: MEGHAJ KUMAR MALLICK ()MCA/25017/18) 2ND YEAR, 4TH SEMESTER
- 3. INTRODUCTION Software testing is a process, to evaluate the functionality of a software application with an intent to find whether the developed software met the specified requirements or not and to identify the defects to ensure that the product is defect-free in order to produce the quality product. Software Testing Definition according to ANSI/IEEE 1059 standard – A process of analyzing a software item to detect the differences between existing and required conditions (i.e., defects) and to evaluate the features of the software item. Software testing is also an important phase of the SDLC.
- 5. STLC STLC stands for Software Testing Life Cycle. STLC is a sequence of different activities performed by the testing team to ensure the quality of the software or the product. STLC is an integral part of Software Development Life Cycle (SDLC). But, STLC deals only with the testing phases. STLC starts as soon as requirements are defined or SRD (Software Requirement Document) is shared by stakeholders. STLC provides a step-by-step process to ensure quality software. In the early stage of STLC, while the software or the product is developing, the tester can analyze and define the scope of testing, entry and exit criteria and also the Test Cases. It helps to reduce the test cycle time along with better quality.
- 6. TESTING IN IT INDUSTRIES It depends on the process and the associated stakeholders of the project(s). In the IT industry, large companies have a team with responsibilities to evaluate the developed software in context of the given requirements. Moreover, developers also conduct testing which is called Unit Testing. In most cases, the following professionals are involved in testing a system within their respective capacities − Software Tester Software Developer Project Lead/Manager End User
- 7. APPLICATION Cost Effective Development : It saves both time & cost of testing. Product Improvement :Diagnosing and fixing the errors identified during proper testing is a time-consuming but productive activity. Test Automation: Test Automation reduces the testing time. Quality Check - Software testing helps in determining following set of properties of any software such as Functionality Reliability Usability Efficiency Maintainability Portability
