Regression Scenario Generator

Runs in browser Test Design

Describe what changed and which modules it touches; the tool derives impact areas, smoke checks, integration scenarios and a suggested regression suite.

What is regression testing, and what does risk-based testing add?

Regression testing re-runs existing tests after a change to confirm that what used to work still does. Because a full suite grows beyond what any release window allows, risk-based testing ranks features by the likelihood and the cost of failure — payment, sign-in, data integrity first — and decides what runs on every build, what runs nightly and what is automated. A regression suite is the natural first target for automation.

How to use Regression Scenario Generator

  1. Describe the change (a PR summary works well).
  2. List the affected modules and any related modules.
  3. Generate and export the scenarios and the tiered suite.

Regression Scenario Generator features

  • Change-type detection: bug fix, new feature, refactor, security, performance, removal
  • Impact areas: direct, related and cross-cutting modules (auth, payments, API, caching…)
  • Smoke, regression and integration scenarios with ids and priorities
  • Four-tier suggested suite from every-build smoke to full regression
  • Extra scenarios for API contracts, database migrations and UI changes

Regression Scenario Generator example

Bug fix in checkout totals

Input:

Change: Fixed discount codes applied twice; touches the checkout API response schema.
Affected: Cart, Checkout
Related: Orders, Invoicing

Output:

SMK-001  Application starts and the changed area loads          Critical
REG-002  Cart: behaviour described by the change                  Critical
REG-011  Original defect cannot be reproduced                     Critical
INT-001  Cart ↔ Orders                                            High
INT-004  API contract compatibility                               Critical

Frequently asked questions about Regression Scenario Generator

What does the tool infer from the change description?

The change type (bug fix, new feature, refactor, security, performance, removal) and cross-cutting concerns such as authentication, payments, API contracts or database migrations — each adds targeted regression scenarios.

What are the tiers?

Tier 1 smoke runs on every build; Tier 2 targeted regression before merge; Tier 3 integration checks between changed and related modules before release; Tier 4 the full regression on the release candidate.

How should I list modules?

Affected modules are the ones the code change touches; related modules consume or feed them (for example Orders and Invoicing when Checkout changes). One per line or comma-separated.

Can I feed it a pull request description?

Yes — paste the PR summary as the change description. Mentions of migrations, endpoints, schemas or UI trigger the corresponding scenarios.
