Study Notes

Test Objectives

Evaluate work products (requirements, user stories, designs, code)
Trigger failures, find defects
Ensure test object coverage
Reduce risk of inadequate software quality
Verify specified requirements fulfillment
Verify compliance with contractual, legal, and regulatory requirements
Provide information for informed stakeholder decisions
Build confidence in test object quality
Validate test object completeness and expected stakeholder functionality

Testing and Debugging

Testing and debugging are separate activities
Testing can trigger failures (dynamic testing) or directly find defects (static testing)
Debugging involves:
- Failure reproduction
- Root cause diagnosis
- Cause elimination
Confirmation testing (by original tester) confirms fixes
Regression testing checks for new failures

Testing's Contributions to Success

Cost-effective defect detection which leads to higher quality test objects.
Directly evaluates test object quality at various SDLC stages to aid release decisions.
Indirectly represents users during development, avoiding extensive and expensive user involvement.
Meets contractual, legal, and regulatory requirements.

Testing and Quality Assurance (QA)

Testing is quality control (QC), a product-oriented, corrective approach
Quality Assurance (QA) is process-oriented, preventive approach, focusing on process improvement.
Both QA and QC use test results
- QC uses results to fix defects.
- QA uses results for process performance feedback.
- QA applies to both development and testing processes, and is everyone's responsibility.

Errors, Defects, Failures, and Root Causes

Human errors lead to defects (faults, bugs), potentially causing failures.
Errors caused by time pressure, work complexity, process, infrastructure, or lack of training and skills
Defects may be in documentation, code, or supporting artifacts
Defects in early SDLC artifacts can lead to later defects
A defect in code may always/sometimes/never result in a failure based on execution context.
Failures can also from environmental factors (e.g., radiation, electromagnetic fields).
