6. What is system testing in Software Testing?
A: System testing is black box testing, performed by the Test Team, and at the start of the system testing the complete system is configured in a controlled environment. The purpose of system testing is to validate an application's accuracy and completeness in performing the functions as designed. System testing simulates real life scenarios that occur in a "simulated real life" test environment and test all functions of the system that are required in real life. System testing is deemed complete when actual results and expected results are either in line or differences are explainable or acceptable, based on client input. Upon completion of integration testing, system testing is started. Before system testing, all unit and integration test results are reviewed by Software QA to ensure all problems have been resolved. For a higher level of testing it is important to understand unresolved problems that originate at unit and integration test levels.
7. What is parallel/audit testing in Software Testing?
A: Parallel/audit testing is testing where the user reconciles the output of the new system to the output of the current system to verify the new system performs the operations correctly. Another Definition:-
With parallel testing, users can easily choose to run batch tests or asynchronous tests depending on the needs of their test systems. Testing multiple units in parallel increases test throughput and lower a manufacturer's
8. What is functional testing in Software Testing?
A: Functional testing is black-box type of testing geared to functional requirements of an application. Test engineers *should* perform functional testing.
9. What is usability testing in Software Testing?
A: Usability testing is testing for 'user-friendliness'. Clearly this is subjective and depends on the targeted end-user or customer. User interviews, surveys, video recording of user sessions and other techniques can be used. Programmers and developers are usually not appropriate as usability testers.
10. What is integration testing in Software Testing?
A: Upon completion of unit testing, integration testing begins. Integration testing is black box testing. The purpose of integration testing is to ensure distinct components of the application still work in accordance to customer requirements. Test cases are developed with the express purpose of exercising the interfaces between the components. This activity is carried out by the test team.

11. What is end-to-end testing in Software Testing?
A: Similar to system testing, the 'macro' end of the test scale is testing a complete application in a situation that mimics real world use, such as interacting with a database, using network communication, or interacting with other hardware, application, or system.
12. What is regression testing in Software Testing?
A: The objective of regression testing is to ensure the software remains intact. A baseline set of data and scripts is maintained and executed to verify changes introduced during the release have not "undone" any previous code. Expected results from the baseline are compared to results of the software under test. All discrepancies are highlighted and accounted for, before testing proceeds to the next level.
Another Definition
Re-testing after fixes or modifications of the software or its environment. It can be difficult to determine how much re-testing is needed, especially near the end of the development cycle. Automated testing tools can be especially useful for this type of testing.
13. What is sanity testing in Software Testing?
A: Sanity testing is performed whenever cursory testing is sufficient to prove the application is functioning according to specifications. This level of testing is a subset of regression testing. It normally includes a set of core tests of basic GUI functionality to demonstrate connectivity to the database, application servers, printers, etc.
Another Definition of Sanity testing
Typically an initial testing effort to determine if a new software version is performing well enough to accept it for a major testing effort. For example, if the new software is crashing systems every 5 minutes, bogging down systems to a crawl, or destroying databases, the software may not be in a 'sane' enough condition to warrant further testing in its current state
14. What is performance testing in Software Testing?
A: Although performance testing is described as a part of system testing, it can be regarded as a distinct level of testing. Performance testing verifies loads, volumes and response times, as defined by requirements.
Another Definition :-
Term often used interchangeably with 'stress' and 'load' testing. Ideally 'performance' testing (and any other 'type' of testing) is defined in requirements documentation or QA or Test Plans

15. What is load testing in Software Testing?
A: Load testing is testing an application under heavy loads, such as the testing of a web site under a range of loads to determine at what point the system response time will degrade or fail.
Another Definition
Load testing simulates the expected usage of a software program, by simulating multiple users that access the program's services concurrently. Load testing is most useful and most relevant for multi-user systems, client/server models, including web servers. For example, the load placed on the system is increased above normal usage patterns, in order to test the system's response at peak loads.
16. What is installation testing in Software Testing?
A: Installation testing is testing full, partial, upgrade, or install/uninstall processes. The installation test for a release is conducted with the objective of demonstrating production readiness. This test includes the inventory of configuration items, performed by the application's System Administration, the evaluation of data readiness, and dynamic tests focused on basic system functionality. When necessary, a sanity test is performed, following installation testing.

19. What is compatibility testing in Software Testing?
A: Compatibility testing is testing how well software performs in a particular hardware, software, operating system, or network environment.
20. What is comparison testing?
A: Comparison testing is testing that compares software weaknesses and strengths to those of competitors' products.
21. What is acceptance testing in Software Testing?
A: Acceptance testing is black box testing that gives the client/customer/project manager the opportunity to verify the system functionality and usability prior to the system being released to production. The acceptance test is the responsibility of the client/customer or project manager, however, it is conducted with the full support of the project team. The test team also works with the client/customer/project manager to develop the acceptance criteria.
22. What is alpha testing in Software Testing?
A: Alpha testing is testing of an application when development is nearing completion. Minor design changes can still be made as a result of alpha testing. Alpha testing is typically performed by a group that is independent of the design team, but still within the company, e.g. in-house software test engineers, or software QA engineers.
Another Definition
Alpha testing is final testing before the software is released to the general public. First, (and this is called the first phase of alpha testing), the software is tested by in-house developers. They use either debugger software, or hardware-assisted debuggers. The goal is to catch bugs quickly. Then, (and this is called second stage of alpha testing), the software is handed over to us, the software QA staff, for additional testing in an environment that is similar to the intended use.

23. What is beta testing in Software Testing?
A: Beta testing is testing an application when development and testing are essentially completed and final bugs and problems need to be found before the final release. Beta testing is typically performed by end-users or others, not programmers, software engineers, or test engineers
Another Definition:- Following alpha testing, "beta versions" of the software are released to a group of people, and limited public tests are performed, so that further testing can ensure the product has few bugs. Other times, beta versions are made available to the general public, in order to receive as much feedback as possible. The goal is to benefit the maximum number of future users.
24. What is stress testing in Software Testing?
A: Stress testing is testing that investigates the behavior of software (and hardware) under extraordinary operating conditions. For example, when a web server is stress tested, testing aims to find out how many users can be on-line, at the same time, without crashing the server. Stress testing tests the stability of a given system or entity. It tests something beyond its normal operational capacity, in order to observe any negative results. For example, a web server is stress tested, using scripts, bots, and various denial of service tools.
Another Definition
Term often used interchangeably with 'load' and 'performance' testing. Also used to describe such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, input of large numerical values, large complex queries to a database system, etc.
25. What is the difference between performance testing and load testing in Software Testing?
A: Load testing is a blanket term that is used in many different ways across the professional software testing community. The term, load testing, is often used synonymously with stress testing, performance testing, reliability testing, and volume testing. Load testing generally stops short of stress testing. During stress testing, the load is so great that errors are the expected results, though there is gray area in between stress testing and load testing.

28. What is incremental testing in Software Testing?
A: Incremental testing is partial testing of an incomplete product. The goal of incremental testing is to provide an early feedback to software developers.
29. What is software testing?
A: Software testing is a process that identifies the correctness, completenes, and quality of software. Actually, testing cannot establish the correctness of software. It can find defects, but cannot prove there are no defects.
30. What is automated testing in Software Testing?
A: Automated testing is a formally specified and controlled method of formal testing approach.
31. What is incremental integration testing in Software Testing?
Continuous testing of an application as new functionality is added; requires that various aspects of an application's functionality be independent enough to work separately before all parts of the program are completed, or that test drivers be developed as needed; done by programmers or by testers.
32. What is the difference between alpha and beta testing in Software Testing?
A: Alpha testing is performed by in-house developers and software QA personnel. Beta testing is performed by the public, a few select prospective customers, or the general public.
33. What is clear box testing in Software Testing?
A: Clear box testing is the same as white box testing. It is a testing approach that examines the application's program structure, and derives test cases from the application's program logic. You CAN learn clear box testing, with little or no outside help.
34. What is boundary value analysis in Software Testing?
A: Boundary value analysis is a technique for test data selection. A test engineer chooses values that lie along data extremes. Boundary values include maximum, minimum, just inside boundaries, just outside boundaries, typical values, and error values. The expectation is that, if a systems works correctly for these extreme or special values, then it will work correctly for all values in between. An effective way to test code, is to exercise it at its natural boundaries.
A: Beta testing is testing an application when development and testing are essentially completed and final bugs and problems need to be found before the final release. Beta testing is typically performed by end-users or others, not programmers, software engineers, or test engineers

35. What is ad hoc testing in Software Testing?
A: Ad hoc testing is a testing approach; it is the least formal testing approach.
Another Definition Similar to exploratory testing, but often taken to mean that the testers have significant understanding of the software before testing it.
36. What is gamma testing in Software Testing?
A: Gamma testing is testing of software that has all the required features, but it did not go through all the in-house quality checks. Cynics tend to refer to software releases as "gamma testing".
37. What is functional testing in Software Testing?
A: Functional testing is same as black box testing. Black box testing a type of testing that considers only externally visible behavior. Black box testing considers neither the code itself, nor the "inner workings" of the software.
38. What is closed box testing in Software Testing?
A: Closed box testing is same as black box testing. Black box testing a type of testing that considers only externally visible behavior. Black box testing considers neither the code itself, nor the "inner workings" of the software.
39. What is bottom-up testing in Software Testing?
A: Bottom-up testing is a technique for integration testing. A test engineer creates and uses test drivers for components that have not yet been developed, because, with bottom-up testing, low-level components are tested first. The objective of bottom-up testing is to call low-level components first, for testing purposes.
40. How do you perform integration testing in Software Testing?
A: First, unit testing has to be completed. Upon completion of unit testing, integration testing begins. Integration testing is black box testing. The purpose of integration testing is to ensure distinct components of the application still work in accordance to customer requirements. Test cases are developed with the express purpose of exercising the interfaces between the components. This activity is carried out by the test team. Integration testing is considered complete, when actual results and expected results are either in line or differences are explainable/acceptable based on client input.
41. When do you choose automated testing in Software Testing?
A: For larger projects, or ongoing long-term projects, automated testing can be valuable. But for small projects, the time needed to learn and implement the automated testing tools is usually not worthwhile. Automated testing tools sometimes do not make testing easier. One problem with automated testing tools is that if there are continual changes to the product being tested, the recordings have to be changed so often, that it becomes a very time-consuming task to continuously update the scripts. Another problem with such tools is the interpretation of the results (screens, data, logs, etc.) that can be a time-consuming task. You can learn to use automated tools, with little or no outside help.
42. What is the difference between system testing and integration testing in Software Testing?
A: System testing is high level testing, and integration testing is a lower level testing. Integration testing is completed first, not the system testing. In other words, upon completion of integration testing, system testing is started, and not vice versa. For integration testing, test cases are developed with the express purpose of exercising the interfaces between the components. For system testing, on the other hand, the complete system is configured in a controlled environment, and test cases are developed to simulate real life scenarios that occur in a simulated real life test environment. The purpose of integration testing in Software Testing is to ensure distinct components of the application still work in accordance to customer requirements. The purpose of system testing, on the other hand, is to validate an application's accuracy and completeness in performing the functions as designed, and to test all functions of the system that are required in real life.
43. What are the parameters of performance testing in Software Testing?
A: The term 'performance testing' is often used synonymously with stress testing, load testing, reliability testing, and volume testing. Performance testing is a part of system testing, but it is also a distinct level of testing. Performance testing verifies loads, volumes, and response times, as defined by requirements.
44. What is disaster recovery testing in Software Testing?
A: Disaster recovery testing is testing how well the system recovers from disasters, crashes, hardware failures, or other catastrophic problems
45. Which of the tools should learn?
A:Learn the most popular software tools (i.e. LabView, LoadRunner, Rational Tools, Winrunner, etc.) -- and you want to pay special attention to LoadRunner and the Rational Toolset.
46.What is the objective of regression testing in Software Testing?
A: The objective of regression testing is to test that the fixes have not created any other problems elsewhere. In other words, the objective is to ensure the software has remained intact. A baseline set of data and scripts are maintained and executed, to verify that changes introduced during the release have not "undone" any previous code. Expected results from the baseline are compared to results of the software under test. All discrepancies are highlighted and accounted for, before testing proceeds to the next level.
47.Is the regression testing performed manually in Software Testing?
A: It depends on the initial testing approach. If the initial testing approach is manual testing, then, usually the regression testing is performed manually. Conversely, if the initial testing approach is automated testing, then, usually the regression testing is performed by automated testing.
48. What is Exploratory testing in Software Testing?
Often taken to mean a creative, informal software test that is not based on formal test plans or test cases; testers may be learning the software as they test it.
49. What is Volume testing in Software Testing?
Volume testing involves testing a software or Web application using corner cases of "task size" or input data size. The exact volume tests performed depend on the application's functionality, its input and output mechanisms and the technologies used to build the application. Sample volume testing considerations include, but are not limited to:
If the application reads text files as inputs, try feeding it both an empty text file and a huge (hundreds of megabytes) text file.
If the application stores data in a database, exercise the application's functions when the database is empty and when the database contains an extreme amount of data.
If the application is designed to handle 100 concurrent requests, send 100 requests simultaneously and then send the 101st request.
If a Web application has a form with dozens of text fields that allow a user to enter text strings of unlimited length, try populating all of the fields with a large amount of text and submit the form.
50. What is Sociability Testing in Software Testing?
This means that you test an application in its normal environment, along with other standard applications, to make sure they all get along together; that is, that they don't corrupt each other's files, they don't crash, they don't consume system resources, they don't lock up the system, they can share the printer peacefully, etc.
51. What is Mutation testing in Software Testing?
A method for determining if a set of test data or test cases is useful, by deliberately introducing various code changes ('bugs') and retesting with the original test data/cases to determine if the 'bugs' are detected. Proper implementation requires large computational resources.
A: Ad hoc testing is a testing approach; it is the least formal testing approach.
Another Definition Similar to exploratory testing, but often taken to mean that the testers have significant understanding of the software before testing it.
36. What is gamma testing in Software Testing?
A: Gamma testing is testing of software that has all the required features, but it did not go through all the in-house quality checks. Cynics tend to refer to software releases as "gamma testing".
37. What is functional testing in Software Testing?
A: Functional testing is same as black box testing. Black box testing a type of testing that considers only externally visible behavior. Black box testing considers neither the code itself, nor the "inner workings" of the software.
38. What is closed box testing in Software Testing?
A: Closed box testing is same as black box testing. Black box testing a type of testing that considers only externally visible behavior. Black box testing considers neither the code itself, nor the "inner workings" of the software.
39. What is bottom-up testing in Software Testing?
A: Bottom-up testing is a technique for integration testing. A test engineer creates and uses test drivers for components that have not yet been developed, because, with bottom-up testing, low-level components are tested first. The objective of bottom-up testing is to call low-level components first, for testing purposes.
40. How do you perform integration testing in Software Testing?
A: First, unit testing has to be completed. Upon completion of unit testing, integration testing begins. Integration testing is black box testing. The purpose of integration testing is to ensure distinct components of the application still work in accordance to customer requirements. Test cases are developed with the express purpose of exercising the interfaces between the components. This activity is carried out by the test team. Integration testing is considered complete, when actual results and expected results are either in line or differences are explainable/acceptable based on client input.
41. When do you choose automated testing in Software Testing?
A: For larger projects, or ongoing long-term projects, automated testing can be valuable. But for small projects, the time needed to learn and implement the automated testing tools is usually not worthwhile. Automated testing tools sometimes do not make testing easier. One problem with automated testing tools is that if there are continual changes to the product being tested, the recordings have to be changed so often, that it becomes a very time-consuming task to continuously update the scripts. Another problem with such tools is the interpretation of the results (screens, data, logs, etc.) that can be a time-consuming task. You can learn to use automated tools, with little or no outside help.
42. What is the difference between system testing and integration testing in Software Testing?
A: System testing is high level testing, and integration testing is a lower level testing. Integration testing is completed first, not the system testing. In other words, upon completion of integration testing, system testing is started, and not vice versa. For integration testing, test cases are developed with the express purpose of exercising the interfaces between the components. For system testing, on the other hand, the complete system is configured in a controlled environment, and test cases are developed to simulate real life scenarios that occur in a simulated real life test environment. The purpose of integration testing in Software Testing is to ensure distinct components of the application still work in accordance to customer requirements. The purpose of system testing, on the other hand, is to validate an application's accuracy and completeness in performing the functions as designed, and to test all functions of the system that are required in real life.
43. What are the parameters of performance testing in Software Testing?
A: The term 'performance testing' is often used synonymously with stress testing, load testing, reliability testing, and volume testing. Performance testing is a part of system testing, but it is also a distinct level of testing. Performance testing verifies loads, volumes, and response times, as defined by requirements.
44. What is disaster recovery testing in Software Testing?
A: Disaster recovery testing is testing how well the system recovers from disasters, crashes, hardware failures, or other catastrophic problems
45. Which of the tools should learn?
A:Learn the most popular software tools (i.e. LabView, LoadRunner, Rational Tools, Winrunner, etc.) -- and you want to pay special attention to LoadRunner and the Rational Toolset.
46.What is the objective of regression testing in Software Testing?
A: The objective of regression testing is to test that the fixes have not created any other problems elsewhere. In other words, the objective is to ensure the software has remained intact. A baseline set of data and scripts are maintained and executed, to verify that changes introduced during the release have not "undone" any previous code. Expected results from the baseline are compared to results of the software under test. All discrepancies are highlighted and accounted for, before testing proceeds to the next level.
47.Is the regression testing performed manually in Software Testing?
A: It depends on the initial testing approach. If the initial testing approach is manual testing, then, usually the regression testing is performed manually. Conversely, if the initial testing approach is automated testing, then, usually the regression testing is performed by automated testing.
48. What is Exploratory testing in Software Testing?
Often taken to mean a creative, informal software test that is not based on formal test plans or test cases; testers may be learning the software as they test it.
49. What is Volume testing in Software Testing?
Volume testing involves testing a software or Web application using corner cases of "task size" or input data size. The exact volume tests performed depend on the application's functionality, its input and output mechanisms and the technologies used to build the application. Sample volume testing considerations include, but are not limited to:
If the application reads text files as inputs, try feeding it both an empty text file and a huge (hundreds of megabytes) text file.
If the application stores data in a database, exercise the application's functions when the database is empty and when the database contains an extreme amount of data.
If the application is designed to handle 100 concurrent requests, send 100 requests simultaneously and then send the 101st request.
If a Web application has a form with dozens of text fields that allow a user to enter text strings of unlimited length, try populating all of the fields with a large amount of text and submit the form.
50. What is Sociability Testing in Software Testing?
This means that you test an application in its normal environment, along with other standard applications, to make sure they all get along together; that is, that they don't corrupt each other's files, they don't crash, they don't consume system resources, they don't lock up the system, they can share the printer peacefully, etc.
51. What is Mutation testing in Software Testing?
A method for determining if a set of test data or test cases is useful, by deliberately introducing various code changes ('bugs') and retesting with the original test data/cases to determine if the 'bugs' are detected. Proper implementation requires large computational resources.
