📝 Essential Knowledge and Skills for Beginners in API Testing Using Postman 🔍 #UnderstandingAPIs What is an API (Application Programming Interface)? Types of APIs: REST, SOAP, GraphQL, etc. Basic Concepts: Endpoints, Status Codes, Headers, and Body 🌐 #HTTPMethods GET: Retrieve data from a server. POST: Send data to a server PUT: Update an existing data. PATCH: Partially update a data. DELETE: Remove a resource. 📊 #HTTPStatusCodes 1xx: Informational responses. 2xx: Success (e.g., 200 OK, 201 Created). 3xx: Redirection. 4xx: Client errors (e.g., 400 Bad Request, 401 Unauthorized, 404 Not Found). 5xx: Server errors (e.g., 500 Internal Server Error). 🛠️ #PostmanInterface Installing and setting up Postman. Understanding the workspace, collections, and environments. Creating and organizing requests within collections. 📬 #SendingRequests How to create and send GET, POST, PUT, DELETE requests. Adding query parameters, path variables, and headers. 📝 #WorkingWithRequestBody Different types of request bodies: raw, form-data, x-www-form-urlencoded. Sending JSON, XML, and other data formats. 📥 #HandlingResponses Reading response status codes. Use this checklist to kickstart your journey into API testing with Postman. 🚀 Happy testing! #APITesting #Postman #SoftwareTesting #QA #BeginnerGuide

𝐀𝐏𝐈 𝐓𝐄𝐒𝐓𝐈𝐍𝐆 𝐀𝐏𝐈 𝐓𝐄𝐒𝐓𝐈𝐍𝐆 involves verifying that an API functions as intended, meets performance requirements, and returns the correct responses. Here are some key aspects and common practices - 🌟𝐓𝐘𝐏𝐄𝐒 𝐎𝐅 𝐀𝐏𝐈 𝐓𝐄𝐒𝐓𝐈𝐍𝐆   1. FUNCTIONAL TESTING :- Ensures the API performs its functions as expected.   2. PERFORMANCE TESTING :- Assesses how the API performs under load and its response times.   3. SECURITY TESTING :- Identifies vulnerabilities and checks for proper authentication and authorization.   4. USABILITY TESTING :- Evaluates the API’s ease of use and clarity of documentation.   5. COMPATIBILITY TESTING :- Ensures the API works across different devices and platforms. 🌟𝐓𝐎𝐎𝐋𝐒 𝐅𝐎𝐑 𝐀𝐏𝐈 𝐓𝐄𝐒𝐓𝐈𝐍𝐆   1. POSTMAN :- Popular for manual testing and automation.   2. SWAGGER :- Useful for designing and documenting APIs.   3. JUNIT/TESTNG :- For automated testing in Java.   4. SOAPUI :- Ideal for testing SOAP and REST APIs.   5. JMETER :- Focused on performance testing. 🌟𝐁𝐄𝐒𝐓 𝐏𝐑𝐀𝐂𝐓𝐈𝐂𝐄𝐒   1. USE CLEAR DOCUMENTATION :- Ensure API documentation is comprehensive and up to date.   2. AUTOMATE TESTS :- Automate repetitive tests to save time and reduce errors.   3. VALIDATE RESPONSES :- Check status codes, response times, and response bodies.   4. TEST EDGE CASES :- Consider unusual input or scenarios to test robustness.   5. MONITOR API PERFORMANCE :- Continuously track performance metrics in production. 🌟𝐂𝐎𝐌𝐌𝐎𝐍 𝐀𝐏𝐈 𝐓𝐄𝐒𝐓𝐈𝐍𝐆 𝐒𝐂𝐄𝐍𝐀𝐑𝐈𝐎𝐒   1. Validating endpoints and methods (GET, POST, PUT, DELETE).   2. Checking for proper error handling and status codes (e.g., 404, 500).   3. Ensuring data integrity in requests and responses.   Testing rate limits and throttling. 🌟 𝐑𝐄𝐅𝐄𝐑𝐄𝐍𝐂𝐄 :- https://lnkd.in/dBJuPj4U + 𝐅𝐎𝐋𝐋𝐎𝐖 𝐔𝐒 𝐅𝐎𝐑 𝐌𝐎𝐑𝐄 𝐒𝐄𝐂𝐔𝐑𝐈𝐓𝐘 𝐔𝐏𝐃𝐀𝐓𝐄𝐒 ! 🌐 redteamintelligence.com.au ☎️ +61429316915 📧 info@redteamintelligence.com.au #API #APItesting #Hacking #developement #APIhacking #SOAPAPI #RESTAPI #Postman #whitehat #redteamintelligence #zeroday #pentesting #redteam #blueteam

Mastering CRUD Operations for Testers As a tester, understanding CRUD operations—Create, Read, Update, and Delete—is crucial for validating modules. These operations are commonly executed using databases or APIs. Database Approach: Use SQL queries to retrieve specific information. For instance, to fetch all user details, execute: SELECT * FROM <Table Name>. API Approach: Platforms like Postman streamline API testing. Obtain the API endpoint and backend URL from your developer. Using Postman, employ the GET method with the provided URL and endpoint. Upon submission, expect to receive the desired data promptly. Verify success by checking the status code; a correct response should yield 200 OK. In case of errors, examine the response for troubleshooting. Which CRUD method would you like to explore next?

Overview of APIs and Testing:- API (Application Programming Interface) allows software applications to communicate 🤝. API Testing verifies functionality, reliability, and security ✅. REST API is a web service that uses standard HTTP methods and data formats like JSON 📡. In contrast, SOAP API uses XML and is more complex 📜. Key aspects to test in APIs include functionality, performance, security, and error handling 🔍. HTTP is the protocol for data transfer, with methods like GET (retrieve) 📥, POST (create) ➕, PUT (update) 🔄, PATCH (partial update) ✏️, DELETE (remove) ❌, and OPTIONS (methods supported) ⚙️. For testing, tools like Postman, SoapUI, and JMeter are used 🛠️. In Postman, create requests, validate responses, and automate tests for efficiency 📊. #apitesting #qa

𝐓𝐲𝐩𝐞𝐬 𝐨𝐟 𝐀𝐏𝐈 𝐓𝐞𝐬𝐭𝐢𝐧𝐠 𝐒𝐦𝐨𝐤𝐞 𝐓𝐞𝐬𝐭𝐢𝐧𝐠 - This is conducted once API development is finalized. It involves verifying that the APIs are operational and ensuring nothing is malfunctioning.

Load testing .... Test for application's capacity by simulating loads. This work was part of my doctoral research experiments.

Types of API Testing

Here's a thing about testing that can be very interesting. Many think testing is just test. Not knowing: 1. The difference of each test phase 2. How to scope the test 3. How to design the test 4. How wide the test coverage is 5. What component(s) each test case touched 6. Impact of incomplete test execution And of course, everyone can say - they tested EVERYTHING. What do you think? 😁
