Summary of Session1: Introduction to API Testing
Summary of "Session 1: Introduction to API Testing"
Main Ideas and Concepts:
-
Introduction to API Testing:
The session introduces API Testing, covering fundamental concepts necessary for understanding the topic. It emphasizes the importance of knowing how web applications work, including the roles of clients and servers.
-
Understanding Software and Testing Types:
Software can be tailored for specific clients or developed as products based on market needs. Various testing types are mentioned, including web testing, mobile app testing, performance testing, security testing, and specifically API Testing.
-
API Definition and Importance:
API (Application Programming Interface) is a backend testing method that focuses on the communication between different software applications. API Testing is crucial as it ensures the backend functionality is working correctly, which is essential for the overall software quality.
-
Tools for API Testing:
- Postman: A tool for manual API Testing.
- REST Assured: A tool for automating API Testing.
The course will cover both manual and automated testing using these tools.
-
Client-server Architecture:
Explanation of Client-server Architecture, including one-tier, two-tier, and three-tier architectures. The three-tier architecture is emphasized as the most common in web applications, consisting of a presentation layer, application layer (business logic), and data layer (database).
-
API Functionality:
APIs act as intermediaries that allow different applications to communicate with each other, regardless of their underlying technology. The session uses analogies (like a waiter in a restaurant) to explain how APIs facilitate communication between clients and servers.
-
Types of APIs:
Two primary types of APIs are discussed: SOAP (Simple Object Access Protocol) and REST (Representational State Transfer), with REST being more widely used in modern applications.
-
Testing Methodologies:
The session outlines the methodologies for API Testing, including understanding the functionality of APIs, sending requests, and validating responses. Key HTTP Methods used in API Testing are introduced: GET, POST, PUT, and DELETE.
-
Payloads and Responses:
Definitions of request payloads (data sent with requests) and response payloads (data received from responses) are provided. The importance of validating both requests and responses during API Testing is emphasized.
-
API vs. Web Services:
The difference between APIs and web services is clarified: all web services are APIs, but not all APIs are web services. Web services are APIs that are available over the internet.
Methodology/Instructions:
- Learning Path:
- Key Concepts to Understand:
- Client-server Architecture (one-tier, two-tier, three-tier).
- Types of APIs (SOAP vs. REST).
- HTTP Methods (GET, POST, PUT, DELETE).
- Payloads in requests and responses.
- Practical Steps for API Testing:
- Familiarize with API endpoints and their functionalities.
- Send requests to APIs and validate the responses.
- Understand the differences between APIs and web services.
Speakers/Sources Featured:
The speaker is an instructor leading the session on API Testing, providing insights and knowledge on the subject matter. Specific names are not mentioned in the subtitles.
This summary encapsulates the key points and methodologies discussed in the introductory session on API Testing.
