Testing Fundamentals-e2e Concepts

1. Pick the best definition of quality

Quality is job one

Zero defects

Conformance to requirements

Work as designed

2. Boundary value testing

Is the same as equivalence partitioning tests

Test boundary conditions on, below and above the edges of input and output equivalence classes

Tests combinations of input circumstances

Is used in white box testing strategy

3. "How much testing is enough?"

Impossible to answer

Easy to answer

The answer depends on the risk for your industry, contract and special requirements

This answer depends on the maturity of your developers

4. Why is testing necessary?

Because testing is good method to make there are not defects in the software

Because verification and validation are not enough to get to know the quality of the software

Because testing measures the quality of the software system and helps to increase the quality

Because testing finds more defects than reviews and inspections.

5. Acceptance test cases are based on what?

Requirements

Design

Code

Decision Table

6. Why does the boundary value analysis provide good test cases?

Because it is an industry standard

Because errors are frequently made during programming of the different cases near the ‘edges’ of the range of values

Because only equivalence classes that are equal from a functional point of view are considered in the test cases

Because the test object is tested under maximal load up to its performance limits

7. 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.

The test manager should do only automated regression testing.

The test manager is justified in her decision because no bug has been fixed in other modules

The test manager should only do confirmation testing. There is no need to do regression testing

Regression testing should be done on other modules as well because fixing one module may affect other modules

8. Which of the following tools would be involved in the automation of regression test?

Data tester

Boundary tester

Capture/Playback

Output comparator.

9. In system testing...

Both functional and non-functional requirements are to be tested

Only functional requirements are tested; non-functional requirements are validated in a review

Only non-functional requirements are tested; functional requirements are validated in a review

Only requirements which are listed in the specification document are to be tested

10. Which of the following is true

Testing is the same as quality assurance

Testing is a part of quality assurance

Testing is not a part of quality assurance

Testing is same as debugging

11. To test a function, the programmer has to write a _________, which calls the function to be tested and passes it test data.

Stub

Driver

Proxy

None of the above

12. Which set of metrics can be used for monitoring of the test execution?

Number of detected defects, testing cost;

Number of residual defects in the test object.

Percentage of completed tasks in the preparation of test environment; test cases prepared

Number of test cases run / not run; test cases passed / failed

None of the above

13. Fault Masking is

Error condition hiding another error condition

Creating a test case which does not reveal a fault

Masking a fault by developer

Masking a fault by a tester

14. During the software development process, at what point can the test process start?

When the code is complete.

When the design is complete.

When the software requirements have been approved.

When the first code module is ready for unit testing

15. One Key reason why developers have difficulty testing their own work is :

Lack of technical documentation

Lack of test tools on the market for developers

Lack of training

Lack of Objectivity

16. An input field takes the year of birth between 1900 and 2004. The boundary values for testing this field are:

. 0,1900,2004,2005

1900, 2004

1899,1900,2004,2005

1899, 1900, 1901,2003,2004,2005

17. Incorrect form of Logic coverage is:

Statement Coverage

Pole Coverage

Condition Coverage

Path Coverage

18. A common test technique is:

Statement and Branch Testing

Usability Testing

Security Testing

Performance Testing

19. In a flight reservation system, the number of available seats in each plane model is an input. A plane may have any positive number of available seats, up to the given capacity of the plane. Using Boundary Value analysis, a list of available – seat values were generated. Which of the following lists is correct?

1, 2, capacity -1, capacity, capacity plus 1

0, 1, capacity, capacity plus 1

0, 1, 2, capacity plus 1, a very large number

0, 1, 10, 100, capacity, capacity plus one

20. Which of the following is a valid collection of equivalence classes for the following problem: An integer field shall contain values from and including 1 to and including 15

Less than 1, 1 through 15, more than 15

Negative numbers, 1 through 15, above 15

Less than 1, 1 through 14, more than 15

Less than 0, 1 through 14, 15 and more

21. Integration testing has following characteristics It can be done in incremental manner Its always done after system testing It includes functional tests It includes non- functional tests

I, II and III are correct

I is correct

I, III and IV are correct

I, II and IV are correct

22. Independent Verification and Validation is:

Done by the Developer

Done by Test Engineers

Done by Management

Done by an Entity Outside the Project’s sphere of influence

23. Why is it necessary to define a Test Strategy?

Starting testing without prior planning leads to chaotic and inefficient test project

A strategy is needed to inform the project management how the test team will schedule the test-cycles

24. Which one of the following are non-functional testing methods?

System testing

Usability testing

Performance testing

Both b & c

25. Which of the following activities differentiate a walkthrough from a formal review?

A walkthrough does not follow a defined process

For a walkthrough individual preparation by the reviewers is optional

A walkthrough requires meeting

A walkthrough finds the causes of failures, while formal review finds the failures
