# Quality Assurance with TracerTM

TracerTM provides Quality Assurance teams with powerful traceability capabilities to ensure comprehensive test coverage, track quality metrics, and maintain visibility across the entire testing lifecycle. This guide demonstrates how QA engineers and test managers can leverage TracerTM to establish robust quality practices.

## Overview: QA Traceability Needs

Quality Assurance requires bidirectional traceability between multiple artifact types to ensure nothing falls through the cracks:

### Critical Traceability Relationships

- **Requirements → Test Cases**: Every requirement must have corresponding test coverage
- **Test Cases → Test Executions**: Track test execution history and results
- **Defects → Test Cases**: Link failures to specific test scenarios
- **Defects → Requirements**: Trace quality issues back to source requirements
- **Test Suites → CI/CD Jobs**: Monitor automated test execution
- **Features → Coverage Reports**: Visualize testing completeness

### Benefits for QA Teams

1. **Complete Visibility**: Identify untested requirements instantly
2. **Impact Analysis**: Understand downstream effects of requirement changes
3. **Traceability Audits**: Generate compliance reports for certifications (ISO, FDA, etc.)
4. **Risk Management**: Prioritize testing based on requirement criticality
5. **Historical Analysis**: Track quality trends across releases

## Test Coverage Analysis and Gap Identification

### Setting Up Coverage Tracking

Create a hierarchical structure for requirements and test cases:

```bash
# Create requirement hierarchy
tracertm item create \
  --type REQUIREMENT \
  --title "User Authentication System" \
  --metadata '{"priority": "High", "compliance": "SOC2"}'

# Link child requirements
tracertm item create \
  --type REQUIREMENT \
  --title "Password Reset Functionality" \
  --link-to AUTH-001 \
  --link-type PARENT_CHILD
```

### Creating Test Cases with Coverage Links

```bash
# Create comprehensive test cases
tracertm item create \
  --type TEST_CASE \
  --title "TC001: Verify password reset email delivery" \
  --link-to REQ-042 \
  --link-type TESTS \
  --metadata '{
    "test_type": "functional",
    "automation_status": "automated",
    "priority": "P1"
  }'

tracertm item create \
  --type TEST_CASE \
  --title "TC002: Validate password complexity rules" \
  --link-to REQ-042 \
  --link-type TESTS \
  --metadata '{
    "test_type": "security",
    "automation_status": "manual",
    "priority": "P0"
  }'
```

### Identifying Coverage Gaps

Use TracerTM's graph queries to find untested requirements:

```bash
# Find all requirements without test coverage
tracertm query graph \
  --node-type REQUIREMENT \
  --filter '{"links.tests": {"$size": 0}}' \
  --format table

# Find requirements with insufficient coverage (<3 tests)
tracertm query graph \
  --node-type REQUIREMENT \
  --filter '{"links.tests": {"$size": {"$lt": 3}}}' \
  --output coverage-gaps.json
```

### Coverage Analysis Report

Generate comprehensive coverage reports:

```python
# Example: Coverage analysis script
from tracertm.api import TracerTMClient

client = TracerTMClient()

# Get all requirements
requirements = client.items.list(type="REQUIREMENT")

coverage_report = []
for req in requirements:
    links = client.links.list(source_id=req.id, type="TESTS")

    coverage_report.append({
        "requirement": req.title,
        "id": req.id,
        "priority": req.metadata.get("priority"),
        "test_count": len(links),
        "status": "Covered" if len(links) > 0 else "Gap"
    })

# Export to CSV for stakeholders
import csv
with open('coverage_report.csv', 'w') as f:
    writer = csv.DictWriter(f, fieldnames=coverage_report[0].keys())
    writer.writeheader()
    writer.writerows(coverage_report)
```

---

## Requirements-to-Test Mapping Workflows

### Structured Test Design Process

**Step 1: Requirements Analysis**

```bash
# Review requirement details
tracertm item show REQ-123 --full

# Check existing test coverage
tracertm links list --source REQ-123 --type TESTS
```

**Step 2: Test Case Design**

Create test cases covering positive, negative, and edge cases:

```bash
# Positive test case
tracertm item create \
  --type TEST_CASE \
  --title "TC-POS-123: Valid login with correct credentials" \
  --link-to REQ-123 \
  --link-type TESTS \
  --metadata '{
    "scenario": "positive",
    "steps": ["Navigate to login", "Enter valid credentials", "Click submit"],
    "expected": "User redirected to dashboard"
  }'

# Negative test case
tracertm item create \
  --type TEST_CASE \
  --title "TC-NEG-123: Invalid login with wrong password" \
  --link-to REQ-123 \
  --link-type TESTS \
  --metadata '{
    "scenario": "negative",
    "steps": ["Navigate to login", "Enter invalid password", "Click submit"],
    "expected": "Error message displayed"
  }'

# Edge case
tracertm item create \
  --type TEST_CASE \
  --title "TC-EDGE-123: Login with SQL injection attempt" \
  --link-to REQ-123 \
  --link-type TESTS \
  --metadata '{
    "scenario": "edge_case",
    "security": true,
    "steps": ["Enter SQL injection string", "Attempt login"],
    "expected": "Input sanitized, attack prevented"
  }'
```

**Step 3: Review and Approval**

```bash
# Update test case status after review
tracertm item update TC-POS-123 \
  --status APPROVED \
  --metadata '{"reviewed_by": "qa_lead", "review_date": "2025-01-15"}'
```

### Mapping Multiple Requirements to Single Test

Some integration tests cover multiple requirements:

```bash
# Create integration test
tracertm item create \
  --type TEST_CASE \
  --title "TC-INT-001: End-to-end checkout process" \
  --metadata '{"test_type": "integration"}'

# Link to multiple requirements
tracertm link create TC-INT-001 REQ-205 --type TESTS
tracertm link create TC-INT-001 REQ-206 --type TESTS
tracertm link create TC-INT-001 REQ-207 --type TESTS
tracertm link create TC-INT-001 REQ-208 --type TESTS
```

---

## Defect Tracking Integration

### Linking Defects to Test Failures

When tests fail, create defects with full traceability:

```bash
# Create defect from test failure
tracertm item create \
  --type DEFECT \
  --title "BUG-456: Login fails with special characters in password" \
  --link-to TC-NEG-123 \
  --link-type FOUND_BY \
  --metadata '{
    "severity": "High",
    "priority": "P1",
    "environment": "Production",
    "reproducible": true,
    "status": "Open"
  }'

# Link defect back to requirement
tracertm link create BUG-456 REQ-123 --type RELATES_TO
```

### Defect Impact Analysis

Understand the full impact of a defect:

```bash
# Find all affected test cases
tracertm query graph \
  --start-node BUG-456 \
  --traverse FOUND_BY \
  --depth 2

# Find affected requirements
tracertm query graph \
  --start-node BUG-456 \
  --traverse RELATES_TO \
  --node-type REQUIREMENT
```

### Defect Lifecycle Tracking

```bash
# Update defect status
tracertm item update BUG-456 \
  --status IN_PROGRESS \
  --metadata '{"assigned_to": "dev_team", "sprint": "Sprint-42"}'

# Link to fix verification test
tracertm item create \
  --type TEST_CASE \
  --title "TC-VER-456: Verify BUG-456 fix" \
  --link-to BUG-456 \
  --link-type VERIFIES \
  --metadata '{"test_type": "verification"}'

# Close defect after verification
tracertm item update BUG-456 \
  --status CLOSED \
  --metadata '{"verified_by": "TC-VER-456", "resolution": "Fixed"}'
```

---

## Regression Testing Traceability

### Building Regression Test Suites

Create regression suites based on historical defects:

```bash
# Find all critical defects from previous releases
tracertm query \
  --type DEFECT \
  --filter '{"metadata.severity": "Critical", "metadata.release": "v1.2"}' \
  --output critical-defects.json

# Create regression test suite
tracertm item create \
  --type TEST_SUITE \
  --title "Regression Suite: Critical Fixes v1.2" \
  --metadata '{"purpose": "regression", "target_release": "v1.3"}'

# Link regression tests to suite
tracertm link create REG-SUITE-001 TC-VER-456 --type CONTAINS
tracertm link create REG-SUITE-001 TC-VER-457 --type CONTAINS
```

### Tracking Regression Test Execution

```bash
# Record test execution results
tracertm item create \
  --type TEST_EXECUTION \
  --title "Regression Run #42 - v1.3-RC1" \
  --link-to REG-SUITE-001 \
  --link-type EXECUTES \
  --metadata '{
    "environment": "Staging",
    "build": "v1.3-RC1",
    "execution_date": "2025-01-20",
    "pass_rate": 95.2,
    "total_tests": 250,
    "passed": 238,
    "failed": 12
  }'

# Link failed tests to new defects
tracertm link create EXEC-042 BUG-789 --type FOUND_DEFECT
```

---

## Test Automation Integration

### Integrating with Test Frameworks

#### Pytest Integration Example

```python
# conftest.py - Pytest plugin for TracerTM
import pytest
from tracertm.api import TracerTMClient

@pytest.fixture(scope="session")
def tracer_client():
    return TracerTMClient()

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
    outcome = yield
    report = outcome.get_result()

    # Record test execution in TracerTM
    if report.when == "call":
        client = TracerTMClient()
        test_id = item.get_closest_marker("tracertm_id")

        if test_id:
            client.items.create(
                type="TEST_EXECUTION",
                title=f"Execution: {item.name}",
                metadata={
                    "test_id": test_id.args[0],
                    "status": "PASS" if report.passed else "FAIL",
                    "duration": report.duration,
                    "timestamp": report.when
                }
            )
```

```python
# test_login.py - Annotated test cases
import pytest

@pytest.mark.tracertm_id("TC-POS-123")
def test_valid_login():
    """Verify login with valid credentials"""
    assert login("user", "password") == True

@pytest.mark.tracertm_id("TC-NEG-123")
def test_invalid_login():
    """Verify login rejection with invalid credentials"""
    assert login("user", "wrong") == False
```

#### Selenium Integration Example

```python
# selenium_tracer_integration.py
from selenium import webdriver
from tracertm.api import TracerTMClient

class TracerTMTestCase:
    def __init__(self, test_case_id):
        self.test_case_id = test_case_id
        self.client = TracerTMClient()
        self.driver = webdriver.Chrome()

    def record_result(self, passed, error_msg=None):
        self.client.items.create(
            type="TEST_EXECUTION",
            title=f"Automated execution: {self.test_case_id}",
            metadata={
                "test_case_id": self.test_case_id,
                "status": "PASS" if passed else "FAIL",
                "error": error_msg,
                "automation_tool": "Selenium"
            }
        )

    def __enter__(self):
        return self

    def __exit__(self, exc_type, exc_val, exc_tb):
        if exc_type:
            self.record_result(False, str(exc_val))
        self.driver.quit()

# Usage
with TracerTMTestCase("TC-INT-001") as test:
    test.driver.get("https://app.example.com/checkout")
    # Test steps...
    test.record_result(True)
```

## Quality Metrics and Reporting

### Key QA Metrics

#### Test Coverage Metrics

```bash
# Generate coverage matrix
tracertm report matrix \
  --rows REQUIREMENT \
  --cols TEST_CASE \
  --output coverage-matrix.html

# Calculate coverage percentage
tracertm query stats \
  --metric coverage \
  --group-by priority
```

#### Defect Density Metrics

```python
# Calculate defects per requirement
from tracertm.api import TracerTMClient

client = TracerTMClient()

requirements = client.items.list(type="REQUIREMENT")
defects = client.items.list(type="DEFECT")

defect_density = {}
for req in requirements:
    related_defects = client.links.list(
        source_id=req.id,
        type="RELATES_TO",
        target_type="DEFECT"
    )
    defect_density[req.id] = len(related_defects)

avg_density = sum(defect_density.values()) / len(requirements)
print(f"Average defect density: {avg_density:.2f} defects/requirement")
```

#### Test Execution Trends

```bash
# Track test pass rates over time
tracertm query \
  --type TEST_EXECUTION \
  --filter '{"metadata.execution_date": {"$gte": "2025-01-01"}}' \
  --aggregate pass_rate \
  --group-by execution_date \
  --output trend-report.csv
```

### Custom QA Dashboards

Build real-time quality dashboards:

```python
# dashboard_generator.py
from tracertm.api import TracerTMClient
import json

client = TracerTMClient()

dashboard = {
    "total_requirements": len(client.items.list(type="REQUIREMENT")),
    "total_test_cases": len(client.items.list(type="TEST_CASE")),
    "open_defects": len(client.items.list(
        type="DEFECT",
        filter={"metadata.status": "Open"}
    )),
    "coverage_gaps": len(client.query(
        type="REQUIREMENT",
        filter={"links.tests": {"$size": 0}}
    )),
    "last_execution": client.items.list(
        type="TEST_EXECUTION",
        sort="-metadata.execution_date",
        limit=1
    )[0]
}

with open("qa-dashboard.json", "w") as f:
    json.dump(dashboard, f, indent=2)
```

## Best Practices for QA Teams

### 1. Establish Traceability Standards

**Naming Conventions**
- Test Cases: `TC-[TYPE]-[ID]` (e.g., `TC-FUNC-001`, `TC-SEC-042`)
- Defects: `BUG-[ID]` or `DEF-[ID]`
- Test Executions: `EXEC-[DATE]-[ID]`

**Metadata Standards**
```json
{
  "test_case": {
    "priority": "P0|P1|P2|P3",
    "test_type": "functional|integration|security|performance",
    "automation_status": "automated|manual|planned",
    "estimated_duration": "minutes"
  },
  "defect": {
    "severity": "Critical|High|Medium|Low",
    "priority": "P0|P1|P2|P3",
    "environment": "Production|Staging|Development",
    "reproducible": true|false
  }
}
```

### 2. Maintain Bidirectional Traceability

Always create links in both directions:
```bash
# Link test to requirement
tracertm link create TC-001 REQ-042 --type TESTS

# Link requirement to test (reverse)
tracertm link create REQ-042 TC-001 --type TESTED_BY
```

### 3. Regular Coverage Audits

Schedule weekly coverage reviews:
```bash
# Automated coverage check (add to cron)
0 9 * * MON tracertm report coverage --email qa-team@company.com
```

### 4. Test Case Maintenance

Keep test cases up-to-date:
```bash
# Find stale test cases (not executed in 90 days)
tracertm query \
  --type TEST_CASE \
  --filter '{
    "metadata.last_execution": {
      "$lt": "2024-11-01"
    }
  }' \
  --output stale-tests.csv
```

### 5. Leverage Graph Queries for Impact Analysis

Before making changes, understand the impact:
```bash
# See full impact of changing a requirement
tracertm query graph \
  --start-node REQ-042 \
  --traverse TESTS,RELATES_TO,DEPENDS_ON \
  --depth 3 \
  --visualize
```

### 6. Integrate with Existing Tools

- **Jira**: Sync defects bidirectionally
- **TestRail**: Import test cases and results
- **Jenkins/GitHub Actions**: Automate traceability recording
- **Slack**: Send coverage alerts

### 7. Quality Gates in CI/CD

Enforce quality standards:
```bash
# Fail build if coverage below threshold
tracertm quality-gate \
  --coverage-threshold 90 \
  --open-defects-max 10 \
  --critical-defects-max 0
```

### 8. Documentation and Knowledge Sharing

Keep test documentation in TracerTM:
```bash
tracertm item update TC-001 \
  --metadata '{
    "test_steps": "Detailed steps...",
    "preconditions": "User must be logged in",
    "test_data": "users.csv",
    "known_issues": "Flaky on slow networks"
  }'
```

### 9. Metrics-Driven Improvement

Track and improve key metrics:
- Test coverage percentage
- Defect escape rate (production bugs)
- Test automation rate
- Test execution time
- Defect resolution time

### 10. Training and Onboarding

Create onboarding checklists:
```bash
tracertm item create \
  --type DOCUMENTATION \
  --title "QA Team Onboarding: TracerTM" \
  --metadata '{
    "checklist": [
      "Complete TracerTM CLI tutorial",
      "Create first test case",
      "Link test to requirement",
      "Record test execution",
      "Generate coverage report"
    ]
  }'
```
