Different Types of API Testing • Smoke Testing- Done after API development is complete. Simply validate if the APIs are working and nothing breaks, basically a Health check, used to ensure System stability, and end-product quality & identify bugs quickly. • Functional Testing- This creates a test plan based on the functional requirements and compares the results with the expected results. Frameworks used- Cypress.io, Selenium, TestComplete (SmartBear), SoapUI etc to perform functional testing. • Integration Testing- This test combines several API calls to perform end-to-end tests. The intra-service communications and data transmissions are tested. • Regression Testing- This test ensures that bug fixes or new features shouldn’t break the existing behaviours of APIs. • Load Testing- This tests applications’ performance by simulating different expected loads. Then we can calculate the capacity of the application and ensure the system meets user expectations (service level agreements (SLAs)) • Stress Testing- Includes deliberately creating high/extreme loads to the APIs and testing if the APIs can function normally such as a DDoS attack. • Security Testing- This tests the APIs against all possible external threats. Can include static/ dynamic Code Analysis and Pen Testing. • UI Testing- This tests the UI interactions with the APIs to make sure the data can be displayed properly. Jasmine test cases are written for the same. • Fuzz Testing- This injects invalid or unexpected input data into the API and tries to crash the API. In this way, it identifies the API vulnerabilities.

API testing APIs (Application Programming Interfaces) enable software systems and applications to communicate and share data. API testing is important as vulnerabilities in APIs may undermine core aspects of a website's confidentiality, integrity, and availability. Popular API Testing Tools 1. Burp Suite Burp Suite is a powerful tool designed for security testing of web applications. It provides various features for scanning and identifying vulnerabilities in APIs. 2. Postman Postman is a popular tool known for its simplicity and ease of use. It allows developers to design, test, and document APIs efficiently. 3. SoapUI SoapUI is an open-source tool specifically designed for testing SOAP and REST APIs. It offers advanced features like data-driven testing, functional testing, and mock services. #Pentesting #ApiTesting #Portswigger #burpSuite

As backend developers, it's important to be familiar with the following API tests: 1. Smoke Testing: Conducted after API development is complete, this test simply validates whether the APIs are functioning correctly and nothing is broken. Tools: Postman, Insomnia. 2. Functional Testing: This involves creating a test plan based on the functional requirements and comparing the results with the expected outcomes. Tools: Postman, SoapUI. 3. Integration Testing: Combines multiple API calls to perform end-to-end tests. It verifies intra-service communications and data transmissions. Tools: Postman. 4. Regression Testing: Ensures that bug fixes or new features do not break the existing functionality of the APIs. Tools: Postman, Selenium. 5. Load Testing: Assesses the application's performance by simulating different loads to determine its capacity. Tools: Grafana k6, Apache JMeter. 6. Stress Testing: Deliberately applies high loads to the APIs to check if they can continue functioning normally under stress. Tools: Grafana k6. 7. Fuzz Testing: Injects invalid or unexpected input data into the API to try and crash it, identifying potential vulnerabilities. Tools: ZAP Special thanks to ByteByteGo for their free system design book. You can read more from their free book.

Levels of Software Testing - Unit Testing: Conducted by developers, unit testing focuses on testing individual components or modules of the software to ensure they function correctly in isolation. • Integration Testing: Carried out by Software Quality Assurance (SQA) teams, integration testing verifies that individual components work together as expected when integrated. System Testing: Another responsibility of SQA, system testing evaluates the entire system's functionality and performance against specified requirements. Acceptance Testing: End users participate in acceptance testing to ensure the software meets their needs and requirements before final deployment. UAT Signoff: Once acceptance testing is successfully completed, the User Acceptance Testing (UAT) signoff officially indicates that the software is ready for production release. _________________________________________ Java Selenium New Batch is Starting Soon Register here to Attend Free Demo: https://lnkd.in/gXjrPQEs Follow Tushar Desai for more insightful updates and tips.

#APITestingTools API Testing Tools🔍 To ensure the effectiveness of Application Programming Interfaces (APIs), it’s essential to use dedicated tools like Postman and SoapUI These tools support data formats such as JSON and XML,making it easier to handle responses. They also facilitate the management of security keys and tokens required for testing private APIs. Use these tools to enhance your API testing process and ensure application reliability!

Here are the 10 most commonly asked API Testing interview questions and answers: ① What is API Testing? API Testing involves verifying application programming interfaces to ensure they meet functionality, reliability, performance, and security requirements. ② What is the difference between REST and SOAP APIs? REST: Lightweight, uses JSON or XML, stateless, and works over HTTP/HTTPS. SOAP: Protocol-based, uses XML, supports stateful operations, and works over HTTP/HTTPS, SMTP, etc. ③ Explain common HTTP methods used in API testing. GET: Retrieve data from the server. POST: Submit data to the server to create a resource. PUT: Update or replace an existing resource. DELETE: Remove a resource from the server. ④ What are the standard HTTP status codes, and what do they mean? 200: OK (Success). 400: Bad Request (Client Error). 401: Unauthorized (Authentication Needed). 500: Internal Server Error (Server Issue). ⑤ What is the difference between API Testing and Unit Testing? API Testing: Validates end-to-end business logic and data flow across systems. Unit Testing: Focuses on individual components of code. ⑥ Which tools are commonly used for API Testing? Postman: For manual testing and script automation. Rest Assured: Java-based library for automated API testing. SoapUI: Used for SOAP and REST API testing. ⑦ What are the different types of API authentication? OAuth: Token-based secure authentication. Basic Auth: Encoded username and password. API Key: Unique identifier to access APIs. ⑧ What are some best practices for writing API test cases? Define endpoint coverage. Test for valid and invalid inputs. Validate response status codes, headers, and payloads. Include edge case scenarios. ⑨ How do you handle errors in APIs? Validate error codes like 4xx (client errors) and 5xx (server errors). Ensure appropriate error messages are returned. Test scenarios for timeout and rate-limiting issues. ⑩ What is a Mock API, and why is it used? Mock APIs simulate the behavior of a real API, allowing testing when the actual API is unavailable or under development. #sqa #apitesting #interviewquestions #qajobsinlahore 🔗 Follow Ahmed Hassan for more insights and updates on Quality Assurance, automation testing, and tips to enhance software quality.
