Software Testing Basics

What is Software Testing? SOFTWARE TESTING  is defined as  activity to check whether the A ctual results match the Expected results  and to ensure that the software system is  Defect / Bug  free ( as per customer requirement) .  Software testing also helps to identify errors, gaps, or missing requirements in contrary to the actual requirements. It can be either done manually or using automated tools. Some prefer saying Software testing as a  White Box  (Testing done by Analyzing code) and  Black Box Testing (Testing done by Analyzing application as per user without digging into the code. Example Verifying login form of application). In simple terms, Software Testing means the Verification of Application Under Test (AUT). Importance of Software Testing  Normal Trend  - --In today's time there are plenty of startups and low budget software companies who donot prefer Software Tester in their company  as it is a extra burden as per wages and other extra facility which they have to prov

STLC(SOFTWARE TESTING LIFE CYCLE) It is a sequence of specific activities conducted during the testing process to ensure software quality goals are met. STLC involves both verification and validation activities. Contrary to popular belief, Software Testing is not just a single/isolate activity, i.e. testing. It consists of a series of activities carried out methodologically to help certify your software product. STLC stands for Software Testing Life Cycle. PHASES OF STLC : Requirement Analysis Test Planning Test case development Test Environment setup Test Execution Test Cycle closure What is Entry and Exit Criteria? Entry Criteria:  Entry Criteria gives the prerequisite items that must be completed before testing can begin. Exit Criteria:  Exit Criteria defines the items that must be completed before testing can be concluded. Requirement Analysis During this phase, test team studies the requirements from a testing point of view to identify the testable requirements. The QA team may in

A software life cycle model is a descriptive representation of the software development cycle. SDLC models might have a different approach but the basic phases and activity remain the same for all the models. 1) Waterfall Model 2) V-Shaped Model 3) Prototype Model 4) Spiral Model 5) Iterative Incremental Model  6) Big Bang Model 7) Agile Model Waterfall Model The  Waterfall Model  was the first Process Model to be introduced. It is very simple to understand and use it. In a  Waterfall  model, each phase must be completed before the next phase can begin and there is no overlapping in the phases.  The waterfall  model is the earliest  SDLC   approach that was used for software development. n “ The Waterfall ” approach, the whole process of  software development  is divided into separate phases. The outcome of one phase acts as the input for the next phase sequentially. This means that any phase in the development process begins only if the previous phase is complete. The waterfall model
