How to Report Bugs in Manual Testing

Bug hunting in software development is not the complete task—it’s the other half of the task which includes reporting the bugs clearly and efficiently so the developers can easily decipher and resolve them. A bad bug report can confuse the team, slow down the fix and even cause deadline misses. That’s why reporting bugs in manual testing should be an art perfected by every tester.

What is Bug Report Bugs in Manual Testing?

A bug report is a document detailing the error or defect faced while conducting a manual test. It provides the developers with information about the issue faced including how the issue was replicated and how something went wrong and what was expected.

For example:

A tester finds the “Add to Cart” button does not work for an e-commerce site. Instead of the usual report of “Cart not working”, a good report explains where, when, and how the issue does happen.

Why is Bug Reporting Important?

• Aids developers in rapidly grasping and reproducing problems
• Saves time by eliminating going-back-and-forth communications
• Improves the quality of the final product
• Provides for responsibility and appropriate defects tracking

How to Report Bugs in Manual Testing (Step-by-Step)

Give a Clearly Defined Bug ID

Every bug should have a unique identifier (e.g., BUG-1234). It can then readily be traced using bug tracking tools like JIRA, Bugzilla, or Trello.

Write a Descriptive Title

The bug title should briefly summarize the issue.

• Incorrect: “Login not working”
• Good: “Login button not clickable in Chrome 120.0 after entering valid credentials”

Give Step-by-Step How-to-Reproduce Instructions

Isolate exact steps so anybody can repeat the issue.

Example:

• Open Chrome (v120.0)
• Go to www.example.com/login
• Enter valid username and password
• Choose “Login”
• Note how nothing occurs

List Expected vs. Actual Results

• Anticipated: User is directed to the dashboard
• Actual: Nothing occurs and no error message appears

Add Screenshots or Videos

Visual validation allows developers to identify the problem easily. You can use software such as Loom, Snagit, or the in-OS screen recorder for this.

Specify Environment Details

Insert:

• Browser/OS version
• Device type (Desktop/Mobile
• Build Num or App version

Attribute Severity & Priority

• Severity: How the bug affects the functionality adversely (Critical, Major, Minor, Trivial)
• Priority: How urgent the bug should be fixed (High, Medium, Low)

Supplementary Notes (if any)

Note any logs, error codes, or patterns observed.

Example of a Well-Structed Bug Report

Bug ID: BUG-2025

Title: Checkout page freezes while using coupon code in Firefox 118.0

Steps to reproduce:

1. Run Firefox 118.0 on Windows 11
2. Go to www.shopnow.com/checkout
3. Add product worth $50
4. Use promo code SAVE20
5. Monitor crash with error message

• Intended Outcome: Order total should be adjusted and discount applied
• Actual Result: The page crashes and the user gets logged out.
• Severity: High
• Priority: Medium
• Attachments: Screenshot + error log

Best Practices for Report Bugs in Manual Testing

• Be concise but clear
• Re-check it first before reporting (to prevent fake bugs)
• Remain factual and not speculative
• Use formal, objective language
• Test the bug in a few browsers/devices if possible

Final Thoughts

Knowing how to report bugs in effective manual testing can avoid hours of confusion for the team and speed up the repair of bugs. It is a good bridge between the tester and the developer such that the issue gets resolved at a faster pace and the end product meets the user’s expectations.
