Manual Testing Interview Questions

List of most important Manual Testing Interview Questions with their answers. It will be helpful for the next interview.

1. What is End-to-End testing?

Testing the complete application in a situation that mimics real-world use, such as interacting with a database, using network communications or interacting with other hardware, applications, or systems if appropriate.

2. What is an Equivalence Class?

A portion of a component’s input or output domains for which the component’s behaviour is assumed to be the same from the component’s specification.

3. What is Equivalence Partitioning?

A test case design technique for a component in which test cases are designed to execute representatives from equivalence classes.

4. What is Exhaustive Testing?

Testing covers all combinations of input values and preconditions for an element of the software which is under test.

5. What is Functional Decomposition?

A technique used during the planning, analysis, and design that creates a functional hierarchy for the software.

6. What is Functional Specification?

A document that describes in detail the characteristics of the product with regard to its intended features.

7. What is Functional Testing?

Testing the features and operational behaviour of a product to ensure they correspond to its specifications. It ignores the internal mechanism of a system or component and focuses solely on the outputs generated in response to selected inputs and execution conditions. A Black Box Testing approach.

8. What is Glass Box Testing?

A synonym for White Box Testing.

9. What is Gorilla Testing?

Testing one particular module, functionality heavily.

10. What is Gray Box Testing?

A combination of Black Box and White Box testing methodologies. Testing software against its specification but using some knowledge of its internal workings.

11. What is High Order Tests?

Black-box tests conducted once the software has been integrated.

12. What is the Independent Test Group (ITG)?

A group of people whose primary responsibility is software testing.

13. What is Inspection?

A group review quality improvement process for written material. It consists of two aspects; product (document itself) improvement and process improvement (of both document production and inspection).

14. What is Integration Testing?

Testing of combined parts of an application to determine if they function together correctly or not. Usually performed after unit and functional testing. This type of testing is especially relevant to client/server and distributed systems.

15. What is Installation Testing?

Confirms that the application under test recovers from expected or unexpected events without loss of data or functionality. Events can include a shortage of disk space, unexpected loss of communication, or power out conditions, etc.

16. What is Load Testing?

Load testing is measuring the behavior of a component or a system with increased load. The increase in load can be in terms of number of parallel users and/or parallel transactions. This helps to determine the amount of load, which can be handled by the component or the software system.

17. What is Localization Testing?

This term refers to making software specifically designed for a specific locality.

18. What is Loop Testing?

A white box testing technique that exercises program loops.

19. What is Metric?

A standard of measurement. Software metrics are the statistics describing the structure or content of a program. A metric should be a real objective measurement of something such as the number of bugs per line of code.

20. What is Monkey Testing?

Testing a system or an Application on the fly, i.e just a few tests here and there to ensure the system or an application does not crash out.

21. What is Negative Testing?

Testing aimed at showing software does not work. Also known as “test to fail”.

22. What is Path Testing?

Testing in which all paths in the program source code are tested at least once.

23. What is Performance Testing?

Testing conducted to evaluate the compliance of a system or component with specified performance requirements. Often this is performed using an automated test tool to simulate a large number of users. Also, know as “Load Testing”.

24. What is Positive Testing?

Testing aimed at showing software works. Also known as “test to pass”.

25. 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.

26. What is Quality Audit?

An independent and systematic 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.

27. 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.

28. What is Structural Testing?

Testing based on an analysis of the internal workings and structure of a piece of software.

29. What is System Testing?

Testing that attempts to discover defects that are properties of the entire system rather than of its individual components.

30. What is Quality Control?

The operational techniques and the activities used to fulfill and verify requirements of quality.

31. What is Quality Management?

That aspect of the overall management function determines and implements the quality policy.

32. What is Quality Policy?

The overall intentions and direction of an organization as regards quality as formally expressed by top management.

33. What is Quality System?

The organizational structure, responsibilities, procedures, processes, and resources for implementing quality management.

34. What is Race Condition?

A cause of concurrency problems. Multiple accesses to a shared resource, at least one of which is a write, with no mechanism used by either to moderate simultaneous access.

35. What is Ramp Testing?

Continuously raising an input signal until the system breaks down.

36. What is Recovery Testing?

Confirms that the program recovers from expected or unexpected events without loss of data or functionality. Events can include a shortage of disk space, unexpected loss of communication, or power out conditions.

37. What is Regression Testing?

Retesting a previously tested program following modification to ensure that faults have not been introduced or uncovered as a result of the changes made.

38. What is Release Candidate?

A pre-release version, which contains the desired functionality of the final version, but which needs to be tested for bugs (which ideally should be removed before the final version is released).

39. What is Sanity Testing?

A brief test of major functional elements of a piece of software to determine if it’s basically operational. 

40. What is Scalability Testing?

Performance testing focused on ensuring the application under test gracefully handles increases in workload.

41. What is Security Testing?

Testing which confirms that the program can restrict access to authorized personnel and that the authorized personnel can access the functions available to their security level.

42. What is Smoke Testing?

A quick-and-dirty test that the major functions of a piece of software work. Originated in the hardware testing practice of turning on a new piece of hardware for the first time and considering it a success if it does not catch on fire.

43. What is Soak Testing?

Running a system at high load for a prolonged period of time. For example, running several times more transactions in an entire day (or night) than would be expected in a busy day, to identify and performance problems that appear after a large number of transactions have been executed.

44. What is Software Requirements Specification?

A deliverable that describes all data, functional and behavioral requirements, all constraints, and all validation requirements for the software.

45. What is Software Testing?

A set of activities conducted with the intent of finding errors in software.

46. What is Static Analysis?

Analysis of a program carried out without executing the program.

47. What is Static Analyzer?

A tool that carries out static analysis.

48. What is Static Testing?

Analysis of a program carried out without executing the program.

49. What is Storage Testing?

Testing that verifies the program under test stores data files in the correct directories and that it reserves sufficient space to prevent unexpected termination resulting from lack of space. This is external storage as opposed to internal storage.

50. What is Stress Testing?

Testing conducted to evaluate a system or component at or beyond the limits of its specified requirements to determine the load under which it fails and how. Often this is performance testing using a very high level of simulated load.
