Quick Answer

This page offers Uncodemy's bug reporting guide as a PDF download. A good bug report lets a developer reproduce, understand and fix a defect without asking questions. The guide gives a template, explains severity and priority, shows the difference between a poor and a good report and lists the evidence to attach.

Why bug reports matter

Finding a defect is only half of a tester's job. The other half is communicating it so that it gets fixed correctly and quickly. A vague report such as checkout broken makes a developer lose time asking for details, trying to reproduce the problem and guessing the conditions. A precise report saves hours and builds trust between testers and developers. Think of a bug report as a small piece of technical writing aimed at a busy reader: it must be accurate, complete and easy to scan, and it must make it obvious what is wrong and how to see it.

01

Anatomy of a good bug report

Field What to write
Title Short, specific summary of the problem and where
Environment Build or version, device, operating system, browser, test environment
Preconditions State and data needed before the steps
Steps to reproduce Numbered, minimal and exact
Expected result What should have happened, referring to the requirement
Actual result What did happen, including exact error text
Severity and priority Technical impact and urgency of fixing
Attachments Screenshot or screen recording, logs, network details
Frequency Always, intermittent, or only once
Additional notes Workaround, related issues, when it started
02

A poor report and a good one

Poor Good
Title: Payment not working Title: Order is placed twice when the Pay button is double-clicked on the card payment page
Steps: Try to pay Steps: 1. Add any product to the cart 2. Go to checkout and choose card payment 3. Enter test card details 4. Double-click Pay
Actual: It fails Actual: Two orders with different IDs are created and the card is charged twice in the test gateway
Expected: Should work Expected: One order is created and the Pay button is disabled after the first click
No attachments Attachments: screen recording, both order IDs and the browser console log
03

Severity and priority are different

Severity describes how serious the defect is for the system: how much it breaks. Priority describes how urgently the business wants it fixed. They often agree but not always. A spelling mistake in the company name on the home page has low severity but may have high priority. A crash in a rarely used admin report has high severity but may have lower priority. Testers normally propose severity; the product owner or team lead sets priority. Using both avoids arguments and lets the team schedule fixes sensibly.

04

Typical severity levels

Severity Meaning Example
Critical System crashes, data loss or security breach; no workaround Payments are charged but orders are lost
High Major feature broken; workaround difficult Users cannot reset their password
Medium Feature partly broken; workaround exists A filter returns wrong results but search still works
Low Minor issue or cosmetic A misaligned button or a typo
05

How to write a report that gets fixed

  1. Reproduce the problem at least twice and note whether it is consistent.
  2. Find the shortest set of steps that triggers it.
  3. Check whether the issue is already reported to avoid duplicates.
  4. Write a specific title that contains the feature and the symptom.
  5. Capture evidence: screenshots, recordings, logs and exact error messages.
  6. State expected and actual results separately and objectively.
  7. Suggest severity, and mention any workaround.
06

Evidence that helps developers

  • → A screenshot with the relevant area highlighted.
  • → A short screen recording of the steps.
  • → Browser console errors and failed network requests.
  • → Application log lines with timestamps and the user or order ID.
  • → The exact build number and environment.
07

Tone and professionalism

Describe the behaviour, not the person who wrote the code. Avoid words such as stupid or obviously broken. Stay factual and respond to questions quickly. Retest the fix promptly and update the report.

08

Common bug reporting mistakes

What to avoid

  • Vague titles and steps.
  • Combining several defects in one report.
  • Missing environment details, so the bug cannot be reproduced.
  • Reporting opinions as defects without reference to a requirement.
  • Duplicates because the tracker was not searched first.
09

A copy-ready bug report template

Quick self-check before you click Submit

  • ✓ Could a new team member reproduce this from my steps alone?
  • ✓ Is the title searchable and specific?
  • ✓ Did I attach evidence?
  • ✓ Did I search for duplicates?
  • ✓ Am I reporting one defect, not three?

FAQ

Frequently Asked Questions

What should a bug report contain?
A specific title, environment, preconditions, numbered steps to reproduce, expected and actual results, severity and priority, evidence such as screenshots or logs, and frequency.
What is the difference between severity and priority?
Severity is the technical impact of the defect. Priority is how urgently it should be fixed from a business point of view.
How do I write a good bug title?
Name the feature and the symptom specifically, for example: order is placed twice when Pay is double-clicked on the card payment page.
What if I cannot reproduce a bug consistently?
Report it as intermittent, describe the conditions where it occurred, attach logs and recordings and note how often you saw it.
Should testers fix the bugs they find?
Normally no. Testers report and verify fixes, while developers fix them, although small teams may share responsibilities.
