What is the MAIN benefit of designing tests early in the life cycle? It helps prevent defects from being introduced into the code.
What is risk-based testing?
Risk-based testing is the term used for an approach to creating a test strategy that is based on prioritizing tests by risk. The basis of the approach is a detailed risk analysis and prioritizing of risks by risk level. Tests to address each risk are then specified, starting with the highest risk first.
A wholesaler sells printer cartridges. The minimum order quantity is 5. There is a 20% discount for orders of 100 or more printer cartridges. You have been asked to prepare test cases using various values for the number of printer cartridges ordered. Which of the following groups contain three test inputs that would be generated using Boundary Value Analysis?
4, 5, 99
What is the KEY difference between preventative and reactive approaches to testing?
Preventative tests are designed early; reactive tests are designed after the software has been produced.
What is the purpose of exit criteria?
To define when a test level is complete.
What determines the level of risk?
The likelihood of an adverse event and the impact of the event
When is used Decision table testing?
Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations. In a decision table the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced.
What is the MAIN objective when reviewing a software deliverable?
To identify defects in any software work product.
Which of the following defines the expected results of a test? Test case specification or test design specification.
Test case specification.
Which is a benefit of test independence?
It avoids author bias in defining effective tests.
As part of which test process do you determine the exit criteria?
Test planning.
What is beta testing?
Testing performed by potential customers at their own locations.
Given the following fragment of code, how many tests are required for 100% decision coverage?
if width > length
then biggest_dimension = width
if height > width
then biggest_dimension = height
end_if
else biggest_dimension = length
if height > length
then biggest_dimension = height
end_if
end_if

Rapid Application Development ?
Rapid Application Development (RAD) is formally a parallel development of functions and subsequent integration. Components/functions are developed in parallel as if they were mini projects, the developments are time-boxed, delivered, and then assembled into a working prototype. This can very quickly give the customer something to see and use and to provide feedback regarding the delivery and their requirements. Rapid change and development of the product is possible using this methodology. However the product specification will need to be developed for the product at some point, and the project will need to be placed under more formal controls prior to going into production.
