Answer from AI
Estimating the effort for tasks involves:
- Task complexity assessment: Determining the time needed to complete specific testing tasks (e.g., writing test cases, manual testing, automation).
- Test automation scope estimation: Forecasting the number of automated tests needed to cover certain functionality.
- Regression testing time estimation: Determining the time required for full or partial regression testing after changes.
- Risk assessment: Identifying potential risks that could impact testing tasks and estimating time to mitigate or bypass them.
- Exploratory testing time: Forecasting time allocated for exploratory testing to find non-obvious defects.
- Test data and environment setup: Estimating time for creating or configuring necessary resources.
- Bug fixing effort: Estimating time developers need to fix identified defects.
- Requirement analysis: Estimating time for fully understanding the requirements.
Various techniques are used for estimation:
- Planning Poker: Team consensus-based estimation.
- Three-Point Estimation: Using optimistic, pessimistic, and most likely scenarios.
- Analogy-based Estimating: Based on past similar tasks.
- Percentage Breakdown: Dividing large tasks into smaller parts and estimating each.
Factors influencing estimation accuracy:
- Task complexity.
- Requirement clarity.
- Test environment stability.
- Availability of test data.
- External dependencies.
- Team experience.
- Hidden risks.
