Added Cypress E2E test and Postman collection

[Abhi007-collab]

What did you build?

Implemented both Cypress and Postman/Newman tests as part of the project.

---

🧪 Cypress (UI E2E)

Created an end-to-end test for the SauceDemo purchase flow:

• Logs in with valid credentials
• Sorts products by price (low to high)
• Adds an item to the cart
• Proceeds to checkout and completes the order
• Asserts that the confirmation message appears successfully

This test demonstrates a realistic UI-driven purchase workflow and ensures the key user journey works as expected.

🔌 Postman/Newman (API Testing)

Built an API test suite for the /posts endpoint on jsonplaceholder.typicode.com.
The Postman collection includes:

1. GET /posts → Verifies that all posts are returned and response status = 200
2. POST /posts → Creates a new post and asserts correct status (201) and response body
3. PUT /posts/{id} → Updates an existing post and checks response structure
4. DELETE /posts/{id} → Deletes a post and verifies correct status code (200)

All requests use dynamic variables and assertions for response validation.
The same collection can be executed via Newman CLI to demonstrate command-line automation.

🧰 Approach and Tools

• Used Postman GUI for building and debugging the API requests
• Used Newman CLI to run the same collection in a scriptable, CI/CD-friendly way
• Used Cypress for browser-based validation of end-to-end purchase flow

Tradeoffs: Focused on clarity and reproducibility rather than full coverage of every edge case.

What would you improve with more time?

• Add negative test cases and more detailed response schema validation for APIs
• Integrate both Cypress and Newman runs into a single CI pipeline
• Parameterize environment URLs and credentials
• Use Page Object Model in Cypress for scalability
• Add data-driven tests and custom reports for better maintainability

Which task did you choose?

• Cypress
• Postman/Newman
