QA Deliverable Ready

Workflows

1) Create a Test Plan

1. Use templates/test-plan.md as your starting point
2. Identify test objectives, scope, assumptions, and constraints
3. Define test levels and types (functional, UI, performance, etc.)
4. Specify environments, test data, tooling, and configuration needs
5. Define entry/exit criteria, deliverables, and reporting cadence
6. Add a risk matrix and mitigation actions
7. Prioritize testing accordingly (risk-based testing)

Template: templates/test-plan.md

2) Generate Test Cases

1. Use templates/test-case.md for individual test cases
2. Convert requirements into test conditions (what to test)
3. Pick a test design technique:
   • Equivalence partitions and boundary values for inputs
   • Decision tables for rule combinations
   • State transitions for lifecycle/flows
   • Use-case/scenario tests for end-to-end journeys
4. Write test cases that are atomic, unambiguous, and traceable
5. Add expected results that are observable and measurable
6. Add priority and risk tags to support risk-based regression
7. Mark automation candidates using stability + value criteria

Templates:

• templates/test-case.md - Individual test case

3) Implement Automation Test Scripts (Playwright)

1. Use templates/playwright-test.md as a template
2. Keep tests readable and aligned with test cases
3. Prefer stable locators (e.g., getByTestId) over brittle selectors
4. Avoid arbitrary sleeps; rely on Playwright auto-waits and explicit assertions
5. Make tests independent (setup preconditions explicitly)
6. Use tagging in test titles (e.g., @smoke, @regression) for suite runs
7. Capture artifacts for triage (screenshots/video/trace) when debugging

Template: templates/playwright-test.md

4) Build and Maintain Regression Suites

1. Use templates/regression-suite.md to define the suite
2. Define suite tiers: smoke (critical paths), sanity (build verification), regression (broad), full (release)
3. Select tests using risk + frequency + criticality + defect history
4. Tag tests consistently and document selection rules
5. Review the suite regularly: remove obsolete coverage, add coverage for escaped defects

Template: Use individual test-case.md templates grouped by priority

5) Create Bug Reports

1. Use templates/bug-report.md as your starting point
2. Reproduce reliably; reduce to minimal steps
3. Note variability (frequency) and scope
4. Capture environment details (build/app version, OS, browser/device, account/role)
5. Describe expected vs actual behavior
6. Include impact; set severity and priority consistently
7. Attach evidence (screenshots, console logs, network traces, Playwright trace)
8. Track lifecycle: triage notes, owner, fix version, verification steps

Template: templates/bug-report.md

Security Guidelines

Credential Handling

NEVER embed real credentials in test cases or code. Use placeholders instead:

Test data best practices:

• Use test accounts provisioned via API or admin panel
• Store credentials in environment variables
• Use Faker.js or similar for generated test data
• Never commit real credentials to version control

URL Navigation Safety

When using Playwright MCP to validate external/untrusted URLs:

1. Verify the URL is from a trusted domain before navigating
2. Avoid executing arbitrary JavaScript from untrusted sources
3. Use sandboxed environments when testing third-party applications
4. Do NOT navigate to URLs provided by untrusted user input without validation

Input Sanitization

All user inputs should be:

• Validated for expected format
• Escaped when used in generated code
• Never passed directly to eval() or shell execution

Anti-Patterns

Verification Checklist

Test Plan:

• Scope clearly defined (in/out)
• Entry/exit criteria specified
• Risks identified with mitigations
• Timeline realistic

Test Cases:

• Each step has expected result
• Preconditions documented
• Test data uses placeholders (no hardcoded credentials)
• Priority assigned

Automated Tests:

• Role-based locators used
• Web-first assertions implemented
• Page Object Model applied
• test.step() grouping for clarity
• Error handling and screenshots
• Credentials loaded from environment variables

Bug Reports:

• Reproducible steps
• Environment documented
• Screenshots/evidence attached
• Severity/priority set

Templates

Available Templates

Template Usage

All templates are located in templates/. To use them:

1. Copy the template to your project directory
2. Fill in placeholders (marked with [brackets] or ${VARIABLE})
3. Customize sections based on your specific needs
4. Remove or add sections as appropriate
5. Save and version control the completed document

Examples

Request:

"Create a test case for user login with valid credentials using the test-case.md template"

Result: The AI will:

1. Open templates/test-case.md
2. Fill in the placeholders with specific details:
   • TC-ID: TC-LOGIN-001
   • Title: Verify valid user login with correct credentials
   • Priority: P0 (Critical)
   • Type: Functional
   • Objective: Verify users can successfully login with valid credentials
   • Preconditions: User account exists in test environment; Browser cookies cleared
   • Test Steps: Fill with specific login steps
   • Test Data: Use ${TEST_USER_EMAIL} and ${TEST_USER_PASSWORD} placeholders
3. Provide the completed test case markdown file

Request:

"Create a bug report for a login form validation issue using the bug-report.md template"

Result: The AI will:

1. Open templates/bug-report.md
2. Generate a unique bug ID (e.g., BUG-1715345678)
3. Fill in the placeholders:
   • Title: Login form accepts invalid email format
   • Severity: High
   • Priority: P1
   • Environment: Fill with actual OS, browser, build details
   • Steps to Reproduce: Add specific, reproducible steps
   • Expected vs Actual: Clear description of the issue
   • Impact: Describe user and business impact
4. Provide the completed bug report markdown file

Request:

"Create Playwright tests for the login flow using the playwright-test.md template"

Result: The AI will:

1. Open templates/playwright-test.md
2. Customize the test describe block for login functionality
3. Add specific test cases:
   • TC-LOGIN-001 @smoke @regression - Valid login
   • TC-LOGIN-002 @regression @negative - Invalid credentials
   • TC-LOGIN-003 @regression @boundary - Password validation
4. Implement test steps using Playwright best practices:
   • Role-based locators (getByRole)
   • Web-first assertions (toBeVisible, toHaveText)
   • test.step() grouping for readability
5. Add security notes about environment variables
6. Provide the completed markdown template with TypeScript code examples

Best Practices (avoids the anti-patterns above)

Test Case Writing

• Be specific and unambiguous; include expected results for each step
• Test one thing per case; document all preconditions and test data
• Include edge cases and boundary values; use consistent naming

Bug Reporting

• Provide minimal, exact reproduction steps; specify environment details
• Include screenshots/videos and describe user and business impact
• Set severity/priority; avoid duplicates with clear, specific titles

Regression Testing

• Automate repetitive tests; prioritize critical paths
• Run smoke tests frequently; review and prune the suite regularly
• Tag consistently; never ignore failed regression tests

Security

• Use environment variables for credentials; never commit secrets
• Validate URLs before navigating; report suspicious content
• Never execute arbitrary JavaScript from user input

Quality Gates (Self-Check)

• Test plan includes scope, approach, risks, environments, entry/exit criteria, deliverables, and metrics
• Test cases are traceable, atomic, deterministic, and include clear oracles and data
• Automation is maintainable (stable locators, minimal flake, independent tests, clear assertions)
• Regression is risk-based, tagged, and curated with clear add/remove rules
• Bug reports are reproducible, actionable, and contain evidence + environment + impact

Troubleshooting

Common Rationalizations

Common shortcuts and "good enough" excuses that erode test quality — and the reality behind each.

"Testing shows the presence, not the absence of bugs." - Edsger Dijkstra

"Quality is not an act, it is a habit." - Aristotle

Verification
