1. API Methods: ??

In the context of API (Application Programming Interface) testing, an "API method" refers to the type of request made to interact with a web service or application. APIs use different methods to define the type of action being performed.

Understanding and appropriately using these API methods is crucial in API testing, as it dictates how data is requested, sent, and manipulated between different software systems.

Understanding the distinctions between PUT, POST, and PATCH methods is pivotal in API testing.

Knowing when to use each method is like wielding a precision tool – it ensures accurate data manipulation, enhances your testing versatility, and positions you as an API testing maestro, contributing significantly to your career growth.

2. API Status Code: ??

API status codes are numeric codes returned by a server in response to a client's request made to an API (Application Programming Interface). These codes provide information about the outcome of the request and the current state of the server. Each status code is a three-digit number grouped into different ranges, indicating different types of responses. Grasping the nuances of API status codes is akin to decoding the language of APIs.

Proficiency in interpreting these codes not only elevates your bug detection skills but also positions you as a critical player in ensuring the robustness and reliability of API functionalities, propelling your career forward.

3. API Authentication & Authorization: ??

Authentication verifies identity, ensuring that the entity making a request is who it claims to be, while authorization determines whether the authenticated entity has the necessary permissions to perform the requested actions within the API. Both are essential components of securing and controlling access to API resources. . Mastery in API authentication and authorization is a career game-changer.

It not only fortifies your applications against security threats but also positions you as an indispensable asset in building secure, high-performance APIs, fostering trust and credibility in your career growth.

4. API Chaining with Rest Assured: ??

API chaining refers to the practice of making multiple API calls in a sequential or chained manner, where the output of one API call becomes the input for the next. This allows developers to orchestrate a series of API requests to achieve a more complex operation or retrieve a set of related data. Unlocking the potential of API chaining with Rest Assured elevates your testing strategies to a new level.

This skill enables you to create comprehensive end-to-end tests, showcasing your ability to ensure seamless API integrations. Such expertise enhances your career prospects by making you an invaluable contributor to scalable and resilient systems.

5. API Headers Automation with Rest Assured

API headers are components of the HTTP request and response messages that provide additional information about the communication between a client and a server in an API (Application Programming Interface). Headers contain metadata that augments the data being sent or received, enabling more context and control over the API interaction. Enhance your API testing with Rest Assured by leveraging the header() method in RequestSpecification.

?? Learn to send single headers, multiple headers, and headers from a map. Explore practical examples for each method and elevate your API testing game!
