SW Testing Chapter 1

Which of the following is a common test objective?

• Comparing actual results to expected results

• 
  Casual analysis

• Preventing defects

• Analyzing cause of failure

A software error can be described as:

• 
  Any ill-advised, substandard, or temporary fix applied to an urgent problem in the (often misguided) belief that doing so will keep a project moving forward.

• 
  A description of the relationship between two or more variables or set members in which the value of one does not influence the values of others.

• The process in which developers determine the root cause of a bug and identify possible fixes

• A mismatch between the program and its specification.

A company recently purchased a commercial off-the-shelf application to automate their bill-paying process. They now plan to run an acceptance test against the package prior to putting it into production. Which of the following is their most likely reason for testing?

• 
  To gather evidence for lawsuit

• To build confidence in the application

• 
  To detect bugs in the application

• To train the users

A test team consistently finds between 90% and 95% of the defects present in the system under test. While the test manager understands that this is a good defect-detection percentage for her test team and industry, senior management and executives remain disappointed in the test group, saying that the test team misses too many bugs. Given that the users are generally
happy with the system and that the failures which have occurred have generally been low impact, which of the following testing principles is most likely to help the test manager explain to these managers and executives why some defects are likely to be missed?

• Pesticide paradox

• 
  Defect clustering

• Exhaustive testing is impossible

• 
  Absence of error fallacy 

Which is not a testing principle:

• Exhaustive testing

• 
  Pesticide paradox

• 
  Defect clustering

• 
  Early testing

Identify the sequence in Bug life cycle

• 
  Open, Fixed, Assigned, Closed

• 
  Assigned, Open, Closed, Fixed

• Open, Assigned, Fixed, Closed

• Assigned, Open, Fixed, Closed

According to the ISTQB Glossary, regression testing is required for what purpose?

• To motivate better unit testing by the programmers.

• To ensure that defects have not been introduced by a modification

• 
  To verify the success of corrective actions.

• To prevent a task from being incorrectly considered completed.

What is true of a Quality system?

• It was delivered on time and budget.

• It costs more than other systems with the same feature

• 
  It meets specified requirements, customer needs

• 
  It is secure

A phone ringing in an adjacent cubicle momentarily distracts a a programmer, causing him to improperly program the logic that checks the upper boundary of an input variable. Later, during system testing, a tester notices that this variable accepts input values. The improperly coded logic for the upper boundary check is :

• 
  The failure

• The root cause

• The defect

• The error

A programmer is working on code which is very complex. This means he is aware that small number of modules or components in the program tend to contain a large number of defects.  Which of the following is a general testing principle that may affect his work?

• 
  Pesticide paradox

• 
  Component testing

• Early testing

• Defect clustering
