How to Write Good Bug Reports

Reproduction steps, severity, environment, screen recordings - the bug report format that gets bugs fixed faster.

A bad bug report is the most expensive QA output. A developer who cannot reproduce a bug spends 30-60 minutes trying before asking QA to clarify. Good bug reports reduce the time from discovery to fix by 50-70%. This guide covers the format that makes bug reports developer-friendly.

No fluff. Real test coverage from QA engineers who find bugs before your users do.

The Anatomy of a Bug Report Developers Can Act On

Most bug reports fail because they describe what the reporter saw, not what the developer needs to know to reproduce it. The developer needs a completely different set of information: the exact steps to reproduce, the exact environment (browser OS device), the expected behavior (what should happen), and the actual behavior (what happened instead). The five required fields: summary (one sentence describing the bug), reproduction steps (numbered, precise, complete), expected vs actual result, environment (browser version OS device), and severity (why this matters).

At Valletta Software, we focus on:

Summary: one sentence - Button disappears when user saves profile on Safari 17 iOS - not UI broken

Reproduction steps: numbered exact - not go to settings and try to save

Expected behavior: what should happen according to spec or common sense

Actual behavior: what actually happened - include error messages verbatim

Environment: browser version OS device screen resolution - all of them

Severity: P1 (data loss service down) P2 (major feature broken) P3 (minor issue) P4 (cosmetic)

Evidence: screen recording (Loom) or screenshot with annotation - not just text description

The Bug Report Practices That Speed Up Fix Time

Good bug reports reduce time-to-fix. These practices are proven across teams.

We give you more than just people. We give you top performers who drive results.

Loom recording: 30-second video showing reproduction - replaces 10 lines of text and saves debugging time

Console logs: include browser console output for frontend bugs - the error message is the clue

Network tab: for API-related bugs include the request response in the report - not just the UI symptom

Minimal reproduction: find the minimum steps needed - remove anything that is not essential

Isolate from data: reproduce with multiple accounts/data sets - is it user-specific or universal

Link to spec: if expected behavior comes from a spec link to it - removes interpretation ambiguity

Duplicate check: search before filing - duplicate reports waste developer time

You lead the work. We handle the rest. From EUR 45/h.

How to Write Good Bug Reports - With QA Engineers Who Make Developers Love QA

Lets keep it simple.

Our QA engineers use AI to write test cases from specs, generate edge-case scenarios automatically, and run visual regression checks across hundreds of screens in minutes - so they spend time on the bugs that matter, not the obvious ones.

Lets keep it simple.

Our QA engineers write bug reports with Loom recordings, console logs, numbered reproduction steps, severity classification, and spec links - reports that get fixed in one developer session
