Test estimation techniques in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of test estimation in software testing?

Test estimation helps predict the time, effort, and resources needed to complete testing activities. It aids in planning and managing the testing process effectively.

beginner

Explain the 'Expert Judgment' technique in test estimation.

Expert Judgment relies on experienced testers or team members to estimate testing effort based on their knowledge and past experience with similar projects.

intermediate

What is the 'Work Breakdown Structure (WBS)' technique in test estimation?

WBS breaks down the testing tasks into smaller, manageable parts. Estimations are made for each part and then combined to get the total effort estimate.

intermediate

Describe the 'Three-Point Estimation' technique.

Three-Point Estimation uses three values: optimistic, pessimistic, and most likely estimates. These are combined to calculate an average estimate that accounts for uncertainty.

beginner

Why is it important to update test estimates during the project?

Updating estimates helps reflect changes in project scope, risks, or progress. It keeps the plan realistic and helps manage expectations.

Which test estimation technique uses past experience and knowledge from team members?

A Delphi Technique

B Work Breakdown Structure

C Expert Judgment

D Three-Point Estimation

Expert Judgment relies on experienced team members to estimate effort based on their knowledge.

What does the Work Breakdown Structure (WBS) technique involve?

A Ignoring task details for quick estimation

B Using three estimates to calculate an average

C Guessing based on intuition

D Breaking tasks into smaller parts and estimating each

WBS divides tasks into smaller parts to estimate effort more accurately.

In Three-Point Estimation, which of the following is NOT used?

A Pessimistic estimate

B Random estimate

C Most likely estimate

D Optimistic estimate

Three-Point Estimation uses optimistic, pessimistic, and most likely estimates, not random estimates.

Why should test estimates be updated during a project?

A To reflect changes and keep plans realistic

B To confuse the team

C To avoid doing testing

D To increase the budget unnecessarily

Updating estimates helps manage changes and keeps the project plan accurate.

Which technique involves gathering estimates anonymously from experts and reaching consensus?

A Delphi Technique

B Expert Judgment

C Work Breakdown Structure

D Three-Point Estimation

Delphi Technique collects anonymous expert opinions to reach a consensus estimate.

Describe three common test estimation techniques and when you might use each.

Think about experience, task breakdown, and handling uncertainty.

Explain why updating test estimates during a project is important and how it helps the testing process.

Consider how projects evolve over time.
