Exploratory testing is an approach where test design and execution happen simultaneously, guided by the tester’s creativity, experience, and intuition. Unlike scripted testing, exploratory sessions generate unique insights that must be captured systematically. This guide explores comprehensive approaches to documenting exploratory testing sessions for maximum value and knowledge preservation.

Understanding Exploratory Testing Documentation

Exploratory testing produces valuable findings, but without proper documentation, insights are lost, bugs go unreported, and learning opportunities disappear. Effective session reports capture the thinking process, observations, and actionable outcomes of exploration.

Bug Report from Exploratory Session

# BUG-4535: Duplicate Order Creation via Browser Back Button

**Discovered in**: Exploratory Session EXP-2025-042
**Reporter**: Maria Garcia
**Date**: 2025-10-10
**Build**: v2.5.3-staging
**Environment**: Staging
**Severity**: High (P0)
**Category**: Functional Defect

## Summary
Using browser back button during payment processing allows duplicate order creation and double charging.

## Steps to Reproduce
1. Add items to cart
2. Proceed to checkout
3. Enter shipping and payment information
4. Click "Pay Now" button
5. While payment is processing (loading spinner visible)
6. Click browser back button
7. Observe checkout form is still active
8. Click "Pay Now" again

## Expected Result
- Browser back should be prevented during payment processing, OR
- Form should be disabled after first submission, OR
- Duplicate order check should prevent second order

## Actual Result
- Back button works during processing
- Checkout form remains enabled
- Second click creates duplicate order
- Credit card charged twice

## Evidence
- Screenshots:
  - `bug_003_duplicate_order_1.png` - First order confirmation
  - `bug_003_duplicate_order_2.png` - Second order confirmation
  - `bug_003_database_screenshot.png` - Both orders in database
- Screen recording: `bug_003_reproduction.mp4`
- Network logs: `bug_003_network_har.har`

## Impact
- **Business**: Financial liability, customer complaints, refund costs
- **User**: Charged twice, confusion, poor experience
- **Frequency**: Medium (users may naturally use back button)

## Reproducibility
100% - Reproduced 3 times consistently

## Suggested Fix
1. Implement idempotency key for order creation
2. Disable form and back button during processing
3. Add duplicate order detection (same items, amount, timestamp)

## Related Issues
- Similar to BUG-3421 (cart duplication, fixed in v2.3)
- May affect STORY-1892 (one-click reorder feature)

## Additional Notes
- Also tested with browser refresh: Same issue occurs
- Tested with F5 reload: Same issue
- May want to implement session locking during checkout

Observation and Risk Report

# RISK-2045: No Maximum Order Value Limit

**Identified in**: Exploratory Session EXP-2025-042
**Reporter**: Maria Garcia
**Date**: 2025-10-10

## Description
The checkout system accepts orders of any value with no upper limit. Testing showed successful processing of $998,990.01 order.

## Risk Analysis
**Potential Issues**:
- Fraud: Large fraudulent orders could be placed
- Payment Gateway: May have transaction limits we exceed
- Inventory: Could oversell if high quantities allowed
- Business Logic: Unusual orders may indicate fraud

**Likelihood**: Low (legitimate users unlikely to order this much)
**Impact**: High (if fraud occurs or payment fails)
**Overall Risk**: Medium

## Current Behavior
- Quantity field accepts up to 9999
- Price × quantity calculated without limit
- Payment gateway accepts (at least up to $1M in sandbox)
- No business rules enforced

## Recommendations
1. Implement maximum order value (suggest $50,000)
2. Add fraud detection triggers for large orders
3. Require manual review for orders >$10,000
4. Add quantity limits per product
5. Implement velocity checks (# of orders per user per day)

## Business Questions
- What is acceptable maximum order size?
- Should high-value orders require special approval?
- Are there payment gateway transaction limits?

**Assigned to**: Product Owner for business rule definition
**Created Story**: STORY-2452

Best Practices

Do’s

  1. Define Clear Charters: Specific mission prevents aimless wandering
  2. Time Box Sessions: 60-90 minutes maintains focus
  3. Document Continuously: Capture notes during, not after exploration
  4. Use Tools: Screen recording, network capturing, log collection
  5. Follow Up: Convert findings to actionable tickets immediately
  6. Share Learnings: Present interesting findings to team

Don’ts

  1. Don’t Explore Without Charter: Random clicking ≠ exploratory testing
  2. Don’t Skip Documentation: Undocumented findings are lost findings
  3. Don’t Multitask: Exploratory testing requires focused attention
  4. Don’t Ignore Small Issues: Minor UX problems compound
  5. Don’t Work in Isolation: Pair sessions increase effectiveness
  6. Don’t Repeat Covered Ground: Check previous session reports first

Conclusion

Effective Exploratory Testing Session Reports transform spontaneous discovery into systematic learning and improvement. By documenting charters, capturing detailed notes, preserving evidence, and creating actionable follow-ups, exploratory testing becomes a powerful complement to scripted testing.

Remember: The value of exploratory testing lies not just in finding bugs, but in understanding the product deeply, questioning assumptions, and uncovering risks that scripted tests miss. Document thoroughly to preserve and share that value.
