Full Stack Learning Path for Test Engineers & Developers 

🌐 1. Web Technologies – Foundation Layer

Learn how the web works under the hood.

• ✅ HTML5, CSS3, JavaScript – structure, styling, and interactivity

• ✅ Browser internals – DOM, rendering, cookies, storage, events

• ✅ HTTP/HTTPS – request methods, status codes, headers

• ✅ Client-Server Architecture – request/response flow

• ✅ Web Debugging Tools – Chrome DevTools, Network tab
  
  

🎨 2. Front-End Technologies

Understand and test the presentation layer.

• ➤ JavaScript (ES6+)

• ➤ Modern Frameworks: React, Angular, or Vue

• ➤ Component Testing: Jest, React Testing Library

• ➤ UI Automation: Selenium, Cypress, Playwright

• ➤ Accessibility Testing: axe-core, Lighthouse
  
  

📦 Bonus: Responsive design, cross-browser issues, CSS frameworks (Bootstrap, Tailwind)

⚙️ 3. Back-End Technologies

The engine behind web applications.

• ➤ Java / Spring Boot – APIs, REST controllers, services

• ➤ Node.js / Express – lightweight JavaScript-based server apps

• ➤ Python / Flask / FastAPI – quick, test-friendly APIs

• ➤ API Testing: Postman, Rest Assured, Karate

• ➤ Authentication: JWT, OAuth2
  
  

🛠 Focus for Testers: Service-layer testing, stubbing/mocking, contract testing

🗄️ 4. Databases

Master both relational and non-relational databases.

➤ Relational (SQL)

• MySQL / PostgreSQL / Oracle

• CRUD operations, joins, indexing

• Data validation and integrity
  
  

➤ NoSQL

• MongoDB, Redis, DynamoDB

• Document vs Key-Value models

• When to use NoSQL over SQL
  
  

🔍 Validation in Tests: JDBC, ORM, direct DB assertions

🔗 5. SOAP Web Services / REST APIs

API communication and testing fundamentals.

• ✅ REST: JSON, endpoints, verbs, idempotency

• ✅ SOAP: XML payloads, WSDL, service operations

• ✅ Tools: Postman (manual), Rest Assured (Java automation), SoapUI (SOAP/REST hybrid)

• ✅ Contract Testing: OpenAPI/Swagger, Pact
  
  

🧱 6. Microservices Architecture

Modern enterprise systems run on microservices.

• ➤ Understand service independence, bounded contexts

• ➤ API Gateway vs direct service calls

• ➤ Message queues: Kafka, RabbitMQ

• ➤ Testing strategies:
  
  

  • Integration vs Contract testing

  • Mocking services with WireMock

  • Service virtualization
    
    

🧪 Test Focus: Inter-service data flow, resilience testing, chaos testing

🤖 8. AI Agents & Automation Intelligence

Next-gen testing and engineering skills.

• ➤ AI Agents in Testing:

  • Self-healing locators

  • Gherkin generation (test case suggestion)

  • AI-based visual testing
    
    

• ➤ Tools: Testim, Mabl, Applitools, ChatGPT-style bots
  
  

• ➤ MBT (Model-Based Testing):

  • Graph models

  • Test case generation from business flows
    
    

🎓 Learning Goal: Augment traditional automation with AI-driven insight and test optimization.

 🔄 ⚡ 7. DevOps & Continuous Testing

The backbone of automation, delivery, and quality at scale.

✅ CI/CD Pipelines
Jenkins, GitHub Actions, GitLab CI, Azure DevOps
Set up pipelines to build, test, and deploy automatically

✅ Infrastructure as Code (IaC)
Docker – containerized test environments
Kubernetes – orchestrate test environments for microservices
Terraform – provisioning cloud infrastructure for test environments

✅ Artifact & Test Result Management
Allure, TestNG/JUnit reports, publishing test artifacts
Storing build/test artifacts in Nexus, Artifactory, or GitHub Packages

✅ Monitoring & Feedback Loops
Slack/email/test dashboards for real-time alerts
Integration with tools like Prometheus, Grafana, ELK Stack for post-deployment QA observability

✅ Version Control & Branching Strategy
Git workflows (feature branches, PR checks, merge gates)
Pre-commit hooks and automated test triggers

 🧩 8. Test Focus in DevOps:

• Run tests as part of every commit (shift-left)

• Test in containers, simulate prod environments

• Automate environment provisioning for integration tests

• Maintain fast feedback cycles with parallelized test execution
