Top 102+ Software Testing Interview Questions

1. What is the MAIN benefit of designing tests early in the life cycle?
It helps prevent defects from being introduced into the code.
2. What is risk-based testing?
Risk-based testing is the term used for an approach to creating a test strategy that is based on prioritizing tests to by risk.

The basis of the approach is a detailed risk analysis and prioritizing of risks by risk level. Tests to address each risk are then specified, starting with the highest risk first.

3. A wholesaler sells printer cartridges. The minimum order quantity is 5. There is a 20% discount for orders of 100 or more printer cartridges.

You have been asked to prepare test cases using various values for the number of printer cartridges ordered.

Which of the following groups contain three test inputs that would be generated using Boundary Value Analysis?
4, 5, 99

4. What is the KEY difference between preventative and reactive approaches to testing?
Preventative tests are designed early; reactive tests are designed after the software has been produced.

5. What is the purpose of exit criteria?
To define when a test level is complete.

6. What determines the level of risk?
The likelihood of an adverse event and the impact of the event

7. When is used Decision table testing?
Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations.

In a decision table the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced.

8. What is the MAIN objective when reviewing a software deliverable?
To identify defects in any software work product.

9. Which of the following defines the expected results of a test? Test case specification or test design specification.
Test case specification.

10. Which is a benefit of test independence?
It avoids author bias in defining effective tests.

11. As part of which test process do you determine the exit criteria?
Test planning.

12. What is beta testing?
Testing performed by potential customers at their own locations.

13. Given the following fragment of code, how many tests are required for 100% decision coverage?
if width > lengththen biggest_dimension = width
if height > width
then biggest_dimension = height
else biggest_dimension = length
if height > length
then biggest_dimension = height

14. You have designed test cases to provide 100% statement and 100% decision coverage for the following

fragment of code. if width > length then biggest_dimension = width else biggest_dimension = length end_if The following has been added to the bottom of the code fragment above. print “Biggest dimension is ” & biggest_dimension print “Width: ” & width print “Length: ” & length How many more test cases are required?
None, existing test cases can be used.

15. Rapid Application Development ?
Rapid Application Development (RAD) is formally a parallel development of functions and subsequent integration. Components/functions are developed in parallel as if they were mini projects, the developments are time-boxed, delivered, and then assembled into a working prototype. This can very quickly give the customer something to see and use and to provide feedback regarding the delivery and their requirements. Rapid change and development of the product is possible using this methodology. However the product specification will need to be developed for the product at some point, and the project will need to be placed under more formal controls prior to going into production.

16. What is the difference between Testing Techniques and Testing Tools?
Testing technique: – Is a process for ensuring that some aspects of the application system or unit functions properly there may be few techniques but many tools.
Testing Tools: – Is a vehicle for performing a test process. The tool is a resource to the tester, but itself is insufficient to conduct testing

17. We use the output of the requirement analysis, the requirement specification as the input for writing …
User Acceptance Test Cases

18. Repeated Testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes in the software being tested or in another related or unrelated software component:
Regression Testing

19. What is component testing ?
Component testing, also known as unit, module and program testing, searches for defects in, and verifies the functioning of software (e.g. modules, programs, objects, classes, etc.) that are separately testable. Component testing may be done in isolation from the rest of the system depend-ing on the context of the development life cycle and the system. Most often stubs and drivers are used to replace the missing software and simulate the interface between the software components in a simple manner. A stub is called from the software component to be tested; a driver calls a component to be tested.
Here is an aswesome video on Unit Testing

20. What is functional system testing ?
Testing the end to end functionality of the system as a whole.
21. What is the benefits of Independent Testing
Independent testers see other and different defects and are unbiased.

22. In a REACTIVE approach to testing when would you expect the bulk of the test design work to be begun?
After the software or system has been produced.

23. What are the different Methodologies in Agile Development Model?
There are currently seven different Agile methodologies that I am aware of:
1. Extreme Programming (XP)
2. Scrum
3. Lean Software Development

Because testing everything is not feasible.

26. Which is the MOST important advantage of independence in testing?
An independent tester may be more effective at finding defects missed by the person who wrote the software.

27. Which of the following are valid objectives for incident reports?
i. Provide developers and other parties with feedback about the problem to enable identification, isolation and correction as necessary.
ii. Provide ideas for test process improvement.

30. What are the phases of a formal review ?
In contrast to informal reviews, formal reviews follow a formal process. A typical formal review process consists of six main steps:
1. Planning
2. Kick-off
3. Preparation
4. Review meeting
5. Rework
6. Follow-up.

31. What is the role of moderator in review process?
The moderator (or review leader) leads the review process. He or she deter-mines, in co-operation with the author, the type of review, approach and the composition of the review team. The moderator performs the entry check and the follow-up on the rework, in order to control the quality of the input and output of the review process. The moderator also schedules the meeting, disseminates documents before the meeting, coaches other team members, paces the meeting, leads possible discussions and stores the data that is collected.

36. Testing activity which is performed to expose defects in the interfaces and in the interaction between integrated components is:
Integration Level Testing

37. What are the Structure-based (white-box) testing techniques ?
Structure-based testing techniques (which are also dynamic rather than static) use the internal structure of the software to derive test cases. They are com-monly called ‘white-box’ or ‘glass-box’ techniques (implying you can see into the system) since they require knowledge of how the software is implemented, that is, how it works. For example, a structural technique may be concerned with exercising loops in the software. Different test cases may be derived to exercise the loop once, twice, and many times. This may be done regardless of the func-tionality of the software.

38. When should be performed Regression testing ?
After the software has changed or when the environment has changed

39. When should testing be stopped?
It depends on the risks for the system being tested

40. What is the purpose of a test completion criterion?
To determine when to stop testing

41. What can static analysis NOT find?
For example memory leaks

42. What is the difference between re-testing and regression testing?
Re-testing ensures the original fault has been removed; regression testing looks for unexpected sideeffects

43. What are the Experience-based testing techniques ?
In experience-based techniques, people’s knowledge, skills and background are a prime contributor to the test conditions and test cases. The experience of both technical and business people is important, as they bring different perspectives to the test analysis and design process. Due to previous experience with similar systems, they may have insights into what could go wrong, which is very useful for testing.

44. What type of review requires formal entry and exit criteria, including metrics? Inspection 45. Could reviews or inspections be considered part of testing?
Yes, because both help detect faults and improve quality

46. An input field takes the year of birth between 1900 and 2004 What are the boundary values for testing this field ? 1899,1900,2004,2005

1 test for statement coverage, 2 for branch coverage
55. What is the difference between re-testing and regression testing?
Re-testing ensures the original fault has been removed; regression testing looks for unexpected side-effects.

56. Which review is normally used to evaluate a product to determine its suitability for intended use and to identify discrepancies?
Technical Review.

57. Why we use decision tables?.
The techniques of equivalence partitioning and boundary value analysis are often applied to specific situations or inputs.

However, if different combinations of inputs result in different actions being taken,

this can be more difficult to show using equivalence partitioning and boundary value analysis, which tend to be more focused on the user interface. The other two specification-based tech-niques, decision tables and state transition testing are more focused on business logic or business rules. A decision table is a good way to deal with combinations of things (e.g. inputs). This technique is sometimes also referred to as a ’cause-effect’ table. The reason for this is that there is an associated logic diagramming technique called ’cause-effect graphing’ which was sometimes used to help derive the decision table

58. Faults found should be originally documented by who?
By testers.

59. Which is the current formal world-wide recognized documentation standard?
There isn’t one.

60. Which of the following is the review participant who has created the item to be reviewed?

61. A number of critical bugs are fixed in software. All the bugs are in one module, related to reports. The test manager decides to do regression testing only on the reports module.
Regression testing should be done on other modules as well because fixing one module may affect other modules.

62. Why does the boundary value analysis provide good test cases?
Because errors are frequently made during programming of the different cases near the ‘edges’ of the range of values.

63. What makes an inspection different from other review types?
It is led by a trained leader, uses formal entry and exit criteria and checklists.
64. Why can be tester dependent on configuration management?
Because configuration management assures that we know the exact version of the testware and the test object.

65. What is a V-Model ?
A software development model that illustrates how testing activities integrate with software development phases

66. What is maintenance testing?
Triggered by modifications, migration or retirement of existing software

67. What is test coverage?
Test coverage measures in some specific way the amount of testing performed by a set of tests (derived in some other way, e.g. using specification-based techniques). Wherever we can count things and can tell whether or not each of those things has been tested by some test, then we can measure coverage.

68. Why is incremental integration preferred over “big bang” integration?
Because incremental integration has better early defects screening and isolation ability

69. When do we prepare RTM (Requirement traceability matrix), is it before test case designing or after test case designing?
The would be before. Requirements should already be traceable from Review activities since you should have traceability in the Test Plan already. This question also would depend on the organisation. If the organisation do test after development started then requirements must be already traceable to their source. To make life simpler use a tool to manage requirements.

70. What is called the process starting with the terminal modules ?
Bottom-up integration

71. During which test activity could faults be found most cost effectively?
During test planning

72. The purpose of requirement phase is
To freeze requirements, to understand user needs, to define the scope of testing

73. How much testing is enough?
The answer depends on the risks for your industry, contract and special requirements 74. Why we split testing into distinct stages? Each test stage has a different purpose.

75. Which of the following is likely to benefit most from the use of test tools providing test capture and replay facilities? a) Regression testing b) Integration testing c) System testing d) User acceptance testing

77. What studies data flow analysis ?
The use of data on paths through the code.

78. What is Alpha testing?
Pre-release testing by end user representatives at the developer’s site.

79. What is a failure?
Failure is a departure from specified behaviour.

80. What are Test comparators ?
Is it really a test if you put some inputs into some software, but never look to see whether the software produces the correct result? The essence of testing is to check whether the software produces the correct result, and to do that, we must compare what the software produces to what it should produce. A test comparator helps to automate aspects of that comparison.

81. Who is responsible for document all the issues, problems and open point that were identified during the review meeting Scribe

82. What is the main purpose of Informal review

Equivalence partitioning

90. “This life cycle model is basically driven by schedule and budget risks” This statement is best suited for…

91. In which order should tests be run?
The most important tests first

92. The later in the development life cycle a fault is discovered, the more expensive it is to fix. why?

98. What can be though of as being based on the project plan, but with greater amounts of detail?
Phase Test Plan
99. What is exploratory testing?
Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution.

The planning involves the cre-ation of a test charter, a short declaration of the scope of a short (1 to 2 hour) time-boxed test effort,

the objectives and possible approaches to be used. The test design and test execution activities are performed in parallel typi-cally

without formally documenting the test conditions, test cases or test scripts.

This does not mean that other, more formal testing techniques will not be used. For example, the tester may decide to use boundary value analysis

but will think through and test the most important boundary values without necessarily writing them down. Some notes will be written during the exploratory-testing session, so that a report can be produced afterwards.
