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.
| 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 |
| 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 |
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.
| 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 |
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.
Paste this into a tracker's description field and fill each line.
