uat-script-author

Overview

UAT scripts are written for stakeholders, not developers: the end user, subject-matter expert (SME), or solution owner runs the script in business language, and the success criterion is "this works for the business," not "no exceptions thrown." Sign-off is a contractual artifact - upon meeting the acceptance criteria the stakeholder signs off, confirming the product meets defined requirements (uat-wiki). This skill emits those scripts.

When to use

• A release requires formal UAT - B2B contracts, regulated industries (finance, healthcare, gov), enterprise SaaS.
• A new feature needs business sign-off before launch.
• A vendor contract requires "customer acceptance" as the payment trigger.
• A migration / rebuild needs the customer to confirm "yes, this is what we wanted" before old system shutdown.

If the test is technical (verify HTTP 200, validate schema), see manual-test-script-author - that's the developer-facing format.

Step 1 - Identify the user journey

Per uat-wiki:

"UAT should be executed against test scenarios representing user journeys rather than technical click-by-click steps."

A UAT script covers one user journey end-to-end, not a single button-click. The journey is what the business stakeholder agreed to in the contract / SOW / acceptance criteria.

Examples:

• "A new customer signs up, places a first order, and receives confirmation."
• "An existing customer updates their billing address and the invoice reflects the change next billing cycle."
• "An admin creates a new user, assigns roles, and the user can log in with the assigned permissions."

Per uat-wiki, select the "three most common or difficult tasks users will perform" - UAT depth, not breadth.

Step 2 - Format

# UAT-001 - New customer first-order flow

**Customer / Stakeholder:** ____________________
**Tester:** ____________________   **Date:** ____________________
**Environment:** UAT   **Build / Version:** v1.4.5

## Business context

This script verifies that a new prospective customer can complete
the full sign-up + first-order journey end-to-end, including
account creation, email confirmation, browsing the catalog, adding
items to cart, completing checkout, and receiving confirmation.

This corresponds to acceptance criterion **AC-1** in the SOW.

## Pre-conditions

- [ ] Test environment is at build `v1.4.5` (verified by tester).
- [ ] Tester has not previously created an account on this UAT
      environment.
- [ ] Test payment method is available: Stripe test card
      4242 4242 4242 4242, any expiry, any CVC.
- [ ] Tester has access to email inbox for `<email>@example.com`.

| Step | Action                                                           | Expected outcome                                                        | Pass | Fail | Notes |
|------|------------------------------------------------------------------|-------------------------------------------------------------------------|:----:|:----:|-------|
| 1    | Open `https://uat.example.com/`. Click "Sign up".                  | Sign-up form appears.                                                    |      |      |       |
| 2    | Enter email `uat-001-<initials>@example.com`, set password.        | "Verify your email" prompt appears.                                      |      |      |       |
| 3    | Open the email inbox; click the verification link.                 | Browser opens to dashboard; greeting shows the user's name.              |      |      |       |
| 4    | Browse the catalog. Search for "BOOK-001".                         | Product page loads showing the item details and "Add to cart" button.   |      |      |       |
| 5    | Click "Add to cart". Click the cart icon.                          | Cart page shows "BOOK-001" qty 1, $24.99.                                 |      |      |       |
| 6    | Click "Checkout". Enter shipping address.                          | Order summary shows shipping cost; tax computed per address.             |      |      |       |
| 7    | Enter payment details (test card 4242…). Click "Place order".      | Confirmation page shows order ID; total matches step 6.                  |      |      |       |
| 8    | Open email inbox; verify confirmation email arrives within 5 min.  | Email shows order ID, items, total, expected delivery date.              |      |      |       |

## Acceptance criteria verification

| AC ID  | Description                                                | Verified in step | Pass / fail |
|--------|------------------------------------------------------------|------------------|:-----------:|
| AC-1.1 | New customer can sign up                                    | 1, 2, 3          |             |

## Sign-off

**Tester:** ____________________  **Date:** ____________________

**Customer / Stakeholder:** ____________________  **Date:** ____________________

By signing, the stakeholder confirms that the system meets
acceptance criteria AC-1.1 through AC-1.5 as defined in the
Statement of Work, dated YYYY-MM-DD.

## Defects raised

| Bug ID | Step | Severity | Description |
|--------|------|----------|-------------|
|        |      |          |             |

Step 3 - Business language, not implementation

UAT scripts are read by stakeholders who don't speak HTTP / DB / React. Translate:

The script is about outcomes, not mechanisms.

Step 4 - Three-tasks rule

Per uat-wiki: "the three most common or difficult tasks users will perform" - UAT covers depth, not breadth.

A UAT round shouldn't have 50 scripts. The pattern:

• 5-10 scripts covering the three most common user journeys.
• 2-5 scripts covering the two or three most difficult tasks (the ones that go wrong most often in the team's history).

If the contract has 30 acceptance criteria, group them into ~10 journeys; one script per journey.

Step 5 - Run the round, log defects, re-test

Execute each script with the stakeholder. For every failed step, log a defect in the "Defects raised" table (Step 2 format) with its step and severity. Verify: every row in the acceptance-criteria table must read pass before sign-off; if any AC fails, hand the defects to the team, fix them, and re-run the affected scripts. Repeat until all acceptance criteria pass - do not proceed to sign-off with an open failing AC.

Step 6 - Sign-off as artifact

The signed UAT scripts go into the customer record:

• Hard-copy file (paper-signed for legal records).
• Soft-copy in the team's contract management system.
• PR comment in the team's repo (referencing the signed PDF).

The sign-off date triggers the contractual milestone (payment, go-live authorization, vendor approval).

Anti-patterns

Limitations

• Stakeholder availability. UAT requires the customer's time; scheduling is the rate-limiter.
• Soft acceptance. Stakeholders may sign off without thoroughly testing; the script's structure helps but doesn't enforce.
• No automation parity. UAT explicitly tests the user experience; automated tests of the same steps don't substitute.
• Per-customer customization. B2B UAT often requires customer-specific scripts (their data, their workflows). Scale by tenancy, not by template.
