QA Engineers! Are You Really Testing HTTP Methods Beyond GET & POST? As QA testers, our job isn’t just to “check if the API works” — it’s to validate every HTTP method and ensure the backend behaves exactly as expected. 1️⃣ GET – Retrieve Data 📌 Example: GET /api/customers ➡ Returns all customers. ✅ In Postman: Select GET, click Send, verify response contains the expected data. ⚡ Test Check: Should not modify data. Status = 200 OK. 2️⃣ POST – Create Resource 📌 Example: POST /api/customers Body: { "name": "Ali", "email": "ali@example.com" } ➡ Creates a new customer record. ✅ In Swagger: Click Try it out, add JSON body, execute, verify new ID in response. ⚡ Test Check: Status = 201 Created. Verify record is added to DB. 3️⃣ PUT – Update / Replace Resource 📌 Example: PUT /api/customers/123 Body: { "name": "Zara", "email": "zara@example.com" } ➡ Replaces the entire record with new data. ✅ In Postman: Select PUT, send full object. ⚡ Test Check: Old data replaced completely. Status = 200 OK. 4️⃣ PATCH – Partial Update 📌 Example: PATCH /api/customers/123 Body: { "name": "Hassan" } ➡ Updates only the provided field. ✅ In Swagger: Execute PATCH → only field updates. ⚡ Test Check: Partial update successful. Status = 200 OK. 5️⃣ DELETE – Remove Resource 📌 Example: DELETE /api/customers/235 ➡ Deletes the record for ID 235. ✅ In Postman: Execute DELETE → then run GET → should return 404 Not Found. ⚡ Test Check: Status = 204 No Content. Record removed from DB. 6️⃣ HEAD – Check Availability 📌 Example: HEAD /api/customers ➡ Returns only headers (no response body). ✅ Used for health checks. ⚡ Test Check: Verify headers like Content-Type, Content-Length. 7️⃣ OPTIONS – Supported Methods 📌 Example: OPTIONS /api/customers ➡ Returns allowed HTTP methods (GET, POST, PUT, etc.). ✅ Used for CORS testing. ⚡ Test Check: Allowed methods list matches API documentation. 8️⃣ TRACE – Debug Request 📌 Example: TRACE /api/main.html ➡ Echoes your request back for debugging. ✅ Rare in production, useful in diagnostics. ⚡ Test Check: Request and response are identical. 9️⃣ CONNECT – Create Tunnel 📌 Example: CONNECT www.example.com:443 ➡ Used for HTTPS tunneling (proxy connections). ⚡ Test Check: Rare in QA testing, but important to understand for security & proxy validation. <~~~~~~#𝑨𝒖𝒕𝒐𝒎𝒂𝒕𝒊𝒐𝒏 #𝑻𝒆𝒔𝒕𝒊𝒏𝒈~~~~~~> 𝑺𝒆𝒍𝒆𝒏𝒊𝒖𝒎 𝑱𝒂𝒗𝒂 (𝑰𝒏𝒄𝒍𝒖𝒅𝒊𝒏𝒈 𝑨𝑰 𝒊𝒏 𝑻𝒆𝒔𝒕𝒊𝒏𝒈 , 𝑮𝒆𝒏𝑨𝑰, 𝑷𝒓𝒐𝒎𝒑𝒕 𝑬𝒏𝒈𝒊𝒏𝒆𝒆𝒓𝒊𝒏𝒈)—𝑻𝒓𝒂𝒊𝒏𝒊𝒏𝒈 𝑺𝒕𝒂𝒓𝒕𝒊𝒏𝒈 𝒇𝒓𝒐𝒎 9𝒕𝒉 𝑴𝒂𝒓𝒄𝒉 𝑹𝒆𝒈𝒊𝒔𝒕𝒆𝒓 𝒏𝒐𝒘 𝒕𝒐 𝒂𝒕𝒕𝒆𝒏𝒅 𝑭𝒓𝒆𝒆 𝑫𝒆𝒎𝒐:https://lnkd.in/dCvuyGMG 𝑶𝑹 𝑱𝒐𝒊𝒏 𝒕𝒉𝒆 𝑾𝒉𝒂𝒕𝒔𝑨𝒑𝒑 𝒈𝒓𝒐𝒖𝒑 𝒇𝒐𝒓 𝒕𝒉𝒆 𝒍𝒂𝒕𝒆𝒔𝒕 𝒖𝒑𝒅𝒂𝒕𝒆𝒔:https://lnkd.in/dH-_Z247 𝐇𝐚𝐩𝐩𝐲 𝐓𝐞𝐬𝐭𝐢𝐧𝐠!
