ISTQB Question Bank 1021 to 1060

Which testing technique do you prefer for the following situations?

<br>

1. Severe time pressure

2. Inadequate specification

• Decision testing

• Error guessing

• Statement testing

• Exploratory testing

Which of the following is false?

• In a system two different failures may have different severities.
• A system is necessarily more reliable after debugging for the removal of a fault.
• A fault need not affect the reliability of a system.
• Undetected errors may lead to faults and eventually to incorrect behavior.

Which of the following is a form of functional testing?

• Boundary value analysis
• Usability testing
• Performance testing
• Security testing

Static analysis is best described as:

• The analysis of batch programs.
• The reviewing of test plans.
• The analysis of program code.
• The use of black box testing.

Which of the following statements about reviews is true?

• Reviews cannot be performed on user requirements specifications.
• Reviews are the least effective way of testing code.
• Reviews are unlikely to find faults in test plans.
• Reviews should be performed on specifications, code, and test plans.

A configuration management system would NOT normally provide:

• Linkage of customer requirements to version numbers.
• Facilities to compare test results with expected results.
• The precise differences in versions of software component source code.
• Restricted access to the source code library.

Considering the following pseudo-code, calculate the MINIMUM number of test cases for statement coverage, and the MINIMUM number of test cases for decision coverage respectively.

• 3, 3

• 2, 3

• 2, 4

• 3, 2

Why are static testing and dynamic testing described as complementary?

• Because they share the aim of identifying defects and find the same types of defect.
• Because they have different aims and differ in the types of defect they find.
• Because they have different aims but find the same types of defect.
• Because they share the aim of identifying defects but differ in the types of defect they find.

In practice, which Life Cycle model may have more, fewer or different levels of development and testing, depending on the project and the software product. For example, there may be component integration testing after component testing, and system integration testing after system testing.

• Water Fall Model
• V-Model
• Spiral Model
• RAD Model

Entry criteria should address questions such as:

<br>

I. Are the necessary documentation, design and requirements information available that will allow testers to operate the system and judge correct behavior.

II. Is the test environment-lab, hardware, software and system administration support ready?

III. Those conditions and situations that must prevail in the testing process to allow testing to continue effectively and efficiently.

IV. Are the supporting utilities, accessories and prerequisites available in forms that testers can use

• I, II and IV

• I, II and III

• I, II, III and IV

• II, III and IV.
