Lesson
Bug reports
Create practical QA artifacts that make testing work clear and repeatable.
Learning goals
Understand the concept, identify where it is used, and apply it in a practical QA task.
Theory explanation
Bug reports is an essential QA topic. In real teams, QA engineers use it to reduce product risk and make release decisions with better evidence.
Key terms
quality, risk, requirement, expected result, actual result, evidence
Real-world example
A team releases a checkout page. QA checks critical flows, documents issues, and helps the team understand release risk.
Step-by-step explanation
Read the requirement, identify risk, design checks, execute tests, document results, communicate findings.
Common mistakes
Testing without clear expected results, skipping edge cases, and writing vague bug reports.
Practical use case
Create a small QA artifact for a login or checkout flow.
Summary
Use Bug reports to make testing structured, clear, and useful for the whole team.

Bug report: checkout button stays disabled
ID: BUG-CHECKOUT-014 Title: Checkout button remains disabled after valid shipping data is entered Environment: Safari 17, macOS, staging Severity: Major Priority: High Steps to reproduce: 1. Add any product to the cart. 2. Open Checkout. 3. Fill all required shipping fields with valid data. 4. Select card payment. Actual result: Checkout button remains disabled.

Bug report quality checklist
- Title is specific and describes the failed behavior. - Environment includes build, browser, OS, device, and test account when relevant. - Steps are numbered and reproducible. - Actual and expected results are separate. - Severity explains user or business impact. - Evidence is attached: screenshot, video, logs, request/response, or database state. - The report avoids blame and focuses on observable facts.
