What's the Software Testing? A set of activities conducted with the intent of finding errors in software. What is the Purpose of Testing? To check whether system is meeting requirement. What is the need for testing? To Make error Free Product and Reduce Development Cost. What is the Outcome of Testing? System, which is bug, free and meet the system requirements. When to start and Stop Testing? When system meets the requirement and there is no change in functionality. After completing testing, what would you deliver to the client? Bug free product. How many types of testing? There are two types of testing* Functional- Black Box Testing * Structural- white Box Testing What is Functional Testing? Testing the features and operational behavior of a product to ensure they correspond to its specifications. Testing that ignores the internal mechanism of a system or component and focuses solely on the outputs generated in response to selected inputs and execution conditions. or Black Box Testing. What is Structural Testing? Testing that takes into account the internal mechanism [structure] of a system or component. Types include branch testing, path testing, statement testing. Or White box testing. What's the Black Box testing? Black Box testing is not based on any knowledge of internal logic. What's the White Box testing?

White Box testing is based on knowledge of internal logic. What is Gray Box Testing? A combination of Black Box and White Box testing methodologies testing a piece of software against its specification but using some knowledge of its internal workings. What are the three techniques of Black Box testing? Three techniques are*.Equivalence Partitioning *.Boundary Value Analysis *.Error guessing What is Equivalence Partitioning? A test case design technique for a component in which test cases are designed to execute representatives from equivalence classes. What's the Boundry Value Analysis? Boundary Valuse Analysis is a test data selection technique in whice values are choosen maximum, minimum, just inside, just outside boundries, typical values, and error values. The hope is then if software work correctly for these values then it's will works for all values in between.

What’s the Error guessing? A test case design technique where the experience of the tester is used to postulate what faults exist, and to design tests specially to expose them. What are the various levels of testing? Unit, Integration, System and Acceptance testing. What's the Unit Testing? Testing of individual component of software. What's the Integration Testing? In Integration Testing, we can test combined parts of application to determine if they work together correctly. How many types of approaches are used in Integration Testing? There are two types of approaches used* Bottom-Up * Top-Down what's the Bottom-up Testing? Approaches to integration testing where the lowest level component are tested first. What's the Top-Down testing? An approach to integration testing where the top-level component are tested first. What's the System Testing? System Testing is third level of Testing In this level we check Functionility of application. What's the Acceptance Testing? A testing conducted to enable a user or customer to determine whether to accept a software project. Why do you go for White box testing, when Black box testing is available? To check code, branches and loops in code. What types of testing do testers perform? Black Box & White Box testing.

Can Automation testing replace manual testing? If it so, how? Yes, if there are many modifications in functionality and it is near impossible to update the automated scripts. What are the entry criteria for Automation testing? Should have stable code. Who's the good software engineer? A good software engineer has "test to break" attitude, an ability to take the point of view of the customers, and strong quality desire. What are the Qualities of a Tester? Should have ability of find out hidden bug as early as possible in SDLC. What is Quality Assurance? All those planned or systematic actions necessary to provide adequate confidence that a product or service is of the type and quality needed and expected by the customer. (or) Bug presentation activity is called QA. What is Quality Audit? A systematic and independent examination to determine whether quality activities and related results comply with planned arrangements and whether these arrangements are implemented effectively and are suitable to achieve objectives.

What is Quality Circle? A group of individuals with related interests that meet at regular intervals to consider problems or other matters related to the quality of outputs of a process and to the correction of problems or to the improvement of quality. What is Quality Control? The operational techniques and the activities used to fulfill and verify requirements of quality. What is Quality Management? That aspect of the overall management function that determines and implements the quality policy. What is Quality Policy? The overall intentions and direction of an organization as regards quality as formally expressed by top management.
