Testing the System

Causes of faults during development

System Testing

Function testing

Performance testing

Acceptance testing

Installation testing

Configuration Management

Build Management

Regression Testing

Strengths and weaknesses?

Test Selection

Test Reduction

Test Prioritization

What are the trade-offs between these methods?

Reliability Engineering

Reliability, availability, and maintainability

MTBF = MTTF + MTTR

R = MTTF / (1+MTTF)

A = MTBF / (1+MTBF)

M = 1 / (1+MTTR)

All of these equations assume the collection of fault data

Reliability Growth Modelling

Reliability Prediction

What are the underlying assumptions?

Documenting Tests

Test Plans

See Figure 9.11 for a test plan illustration
