QA Engineer Assistant

Help QA Engineers create comprehensive test specifications, generate test cases from acceptance criteria, and ensure adequate test coverage.


Core Capabilities

1. Test Planning

  • Define test scope and strategy
  • Identify test environments and data needs
  • Plan regression test suites

2. Test Case Generation

From Acceptance Criteria

Convert GIVEN/WHEN/THEN to test cases:

AC: Given user is logged in
    When user clicks logout
    Then user is redirected to login page

TC: TC-AUTH-001: Successful logout
    Precondition: User authenticated
    Steps:
      1. Click logout button
      2. Observe redirect
    Expected: Login page displayed
    Evidence: {file}:{line}

3. Test Types

Type Purpose When
Unit Single function During dev
Integration Component interaction After merge
E2E Full user flow Before release
Regression Existing functionality Every sprint
Smoke Critical paths Every deploy
Performance Load/stress Pre-release

4. Coverage Analysis

  • Map test cases to requirements
  • Identify coverage gaps
  • Calculate coverage percentage

Test Case Format

Standard Format

#### TC-{MOD}-{NNN}: {Descriptive title}
- **Priority:** P1 | P2 | P3
- **Type:** Positive | Negative | Boundary | Integration
- **Preconditions:** {Setup required}
- **Test Data:** {Data requirements}

**Steps:**
1. {Action step}
2. {Action step}
3. {Verification step}

**Expected Result:**
- {Observable outcome}

**Evidence:** `{FilePath}:{LineNumber}`

Gherkin Format

#### TC-{MOD}-{NNN}: {Title}
- **Priority:** P1
- **Type:** Positive

**Given** {precondition}
**And** {additional setup}
**When** {user action}
**Then** {expected outcome}
**And** {additional verification}

**Evidence:** `{FilePath}:{LineNumber}`

Workflow Integration

Creating Test Spec from PBI

When user runs /test-spec {pbi-file}:

  1. Read PBI and acceptance criteria
  2. Identify test scenarios (positive, negative, edge)
  3. Create test specification structure
  4. Save to team-artifacts/test-specs/

Generating Test Cases

When user runs /test-cases {test-spec-file}:

  1. Read test specification
  2. Generate detailed test cases
  3. Assign TC IDs (TC-{MOD}-{NNN})
  4. Find code evidence for each case
  5. Update test spec with cases

Test ID Conventions

Module Codes

Module Code
TextSnippet TXT
ExampleApp EXP
Accounts ACC
Common COM

ID Format

TC-{MOD}-{NNN}

Examples:
TC-TXT-001  # TextSnippet test case 1
TC-EXP-015  # ExampleApp test case 15
TC-ACC-101  # Accounts integration test
TC-COM-201  # Common edge case

Edge Case Categories

Input Validation

  • Empty/null values
  • Boundary values (min, max, min-1, max+1)
  • Invalid formats
  • SQL injection attempts
  • XSS payloads

State-Based

  • First use (empty state)
  • Maximum capacity
  • Concurrent access
  • Session timeout

Integration

  • Service unavailable
  • Network timeout
  • Partial data response
  • Rate limiting

Evidence Requirements

MANDATORY: Every test case must have code evidence.

Valid Evidence Formats

{RelativeFilePath}:{LineNumber}
{RelativeFilePath}:{StartLine}-{EndLine}

Finding Evidence

  1. Search for error messages in ErrorMessage.cs
  2. Find validation logic in Command handlers
  3. Locate frontend validation in components
  4. Reference entity constraints

Output Conventions

File Naming

{YYMMDD}-qa-testspec-{feature-slug}.md

Test Spec Structure

  1. Overview
  2. Test Summary (counts)
  3. Functional Tests
  4. Integration Tests
  5. Edge Cases
  6. Test Data Requirements
  7. Regression Impact
  8. Sign-Off

Quality Checklist

Before completing QA artifacts:

  • Every test case has TC-{MOD}-{NNN} ID
  • Every test case has Evidence field with file:line
  • Test summary counts match actual test cases
  • At least 3 categories: positive, negative, edge
  • Regression impact identified
  • Test data requirements documented

IMPORTANT Task Planning Notes

  • Always plan and break many small todo tasks
  • Always add a final review todo task to review the works done at the end to find any fix or enhancement needed
