Chapter 4

Question 1

A procedure used to derive and or select test cases.

Answer 1

Test Technique

Question 2

A procedure to derive and or select test cases based on analysis of the specification, either functional or non functional of a component or system without reference to its internal structure.

Test what the software does not how it does it.
Functional and non functional.

Answer 2

Black box test technique

Question 3

A procedure to derive and or select test cases based on an analysis of the internal structure of a component or system

Answer 3

White box test technique

Question 4

Degee to which specified items have been determined to have been exercised by a test suite expressed as a percentage

Answer 4

Coverage

Question 5

A procedure to derive or select test cases based on testers experience, knowledge and intuition.

Answer 5

Experience based test technique

Question 6

4 black box test techniques

Answer 6

○ Equivalence partitioning
○ Boundary value analysis
○ Decision table testing
State transition testing

Question 7

A black box test technique in which test cases are designed to exercise equivalence paritions by using one representative member of each partition.

Answer 7

ep

Question 8

A black box test technique in which test cases are designed to exercise equivalence paritions by using one representative member of each partition.

Answer 8

Eqivalence partitioning

Question 9

Black box test technique is which test cases are designed based on boundary values

Answer 9

Boudary value analysis

Question 10

Black box test technique using state transition diagram or state table to derive test caes to evaluate whether the test item successfully executes valid transitions and blocks invalid transitions.

Answer 10

State transition testing

Question 11

Black box test technique in which test cases are deisgned to execute scenarios of use cases.

Answer 11

Use case testing

Question 12

Coverage equation

Answer 12

Coverage = number of coverage items exercised / total number of coverage iteams x 100

Question 13

The percentage of executable statements that have been exercised by a test suite

Answer 13

Statement coverage

Question 14

The coverage of decision outcomes. The percentage of decision outcomes that have been exercised by a test suite.

Answer 14

Decision coverage

Question 15

Statement coverage is said to make sure that every statement in the code is executed at least once. Decision/branch coverage is said to test that each branch/output of a decisions is tested, i.e. all statements in both false/true branches will be executed.

Answer 15

Decision vs statement coverage

Question 16

A test technique in which tests are derived on basis of testers knowledge of past failures or general knowledge of failure modes

Answer 16

Error guessing

Question 17

An approach to testing whereby testeres dynamically design and execute tests based on their knowledge exploration of the test item and results of previous tests.

Answer 17

Exploratory testing

Question 18

Experience based technique whereby the experienced tester uses a high level list of items to be noted, checked or remembered or a set of rules or criteria against which a product has to be verified.

Answer 18

Checklist based testing
