Questions and Answers

What is test design?

  • A stage in the software development process where code is written
  • A stage in the quality assurance process where testing activities are carried out
  • A stage in the software development process where requirements are gathered
  • A stage in the quality assurance process where test scenarios are created and testing activities are outlined for a project (correct)

What is the purpose of test design?

  • To structure QA routines for better requirement coverage (correct)
  • To gather requirements for the software system
  • To test the software system after it has been developed
  • To write code for the software system

What are test design techniques?

  • Strategies that help gather requirements for the software system
  • Strategies that help implement the software system
  • Strategies that help write better test cases (correct)
  • Strategies that help design the software system

Study Notes

  • Test design is a stage in the quality assurance process where test scenarios are created and testing activities are outlined for a project.
  • Test design helps structure QA routines for better requirement coverage.
  • Test design techniques are strategies that help write better test cases.
  • Using test design techniques reduces the number of necessary test scenarios while ensuring broad requirements coverage.
  • Five commonly-used test design techniques are equivalent class partitioning, boundary value analysis, state transition, pairwise testing, and error guessing.
  • Equivalent class partitioning splits test data into classes where all elements are similar in some way.
  • Boundary value analysis checks boundary values, those that are at the ‘borders’ of the classes.
  • State transition visualizes the states of a software system at different time frames and stages of usage.
  • Pairwise testing creates unique pairs to test a huge amount of incoming data in different combinations.
  • Error guessing predicts where errors are likely to appear, relying on previous experience, knowledge of the system, and product requirements.
