Software Testing Quiz

If you are testing a module of code, how do you determine the level of decision coverage you have achieved?

• By taking the number of decision outcomes you have tested and dividing that by the total number of decision outcomes in the module

• By taking the number of decisions you have tested and dividing that by the total lines of code in the module

• By taking the number of decisions you have tested and dividing that by the total number of decisions in the module

• By taking the number of decisions you have tested and dividing that by the total number of executable statements in the module

Which of the following is an extension of equivalence partitioning?

• State Transition Testing

• Decision Testing

• Decisions Table

• Boundary Value Analysis

Which is not true-The black box tester?

• should be able to understand a functional specificationor requirements document

• is creative to find the system's weaknesses

• is highly motivated to find faults

• should be able to understand the source code.

If the temperature falls below 18 degrees, the heating is switched on. When the temperature reaches 21 degrees, the heating is switched off. What is the minimum set of test input values to cover all valid equivalence partitions?

• 17,18,20 and 21 degrees

• 16 and 26 degrees

• 18,20 and 22 degrees

• 17,18,20 and 22 degrees

Given the state diagram, which test case is the minimum series of valid transitions to cover every state?

• SS-S1-S2-S4-S1-S3-ES

• SS-S1-S4-S2-S1-S3-ES

• SS-S1-S2-S4-S1-S3-S4-S1-S3-ES

• SS-S1-S2-S3-S4-ES

How is statement coverage determined?

• Number of executable statements tested divided by the total number of executable statements

• Number of possible test case outcomes divided by the total number of function points

• Number of test decision points divided by the number of test cases

• Number of decision outcomes tested divided by the total number of decision outcomes

Given the following program fragment:

If day =Monday then

statement a

Else

statement b

End if

If day = Tuesday

then statement c

End if

What is the minimum number of test cases needed to achieve 100% statement coverage?

• 3

• 2

• 1

• 4

Using  the  diagram, which  test  suite  will  uncover  invalid  state  transitions  for employee  status  reporting  software?

• Prospective - Active - Resigned - Active - Terminated - Purged

• Prospective - Active - On Leave - Active - Resigned - Retired

• Prospective - Active - Retired - Active - On Leave - Purged

• Prospective - Active - On Leave - Active - Retired - Active

Regression  testing  can  be  applied  to  which  of  the  following?

I. Functional Testing

II. Non-Functional Testing

III. Structural Testing

• I and II only

• II and III only

• I, II, III

• I and III only

Which one of the following best describes a characteristic of a keyworddriven test execution tool?

• Actions of testers recorded in a script that is rerun several times

• The ability to log test results and compare them against the expected results, stored in a text file.

• A table with test input data, action words, and expected results, controls execution of the system under test.

• Actions of testers recorded in a script that is run with several sets of test input data.
