A complete introduction to API Testing. πŸ§ͺ

API testing is performed to test whether a particular API meets some pre-defined parameters or not.

Let's talk more about API Testing πŸ§΅πŸ‘‡πŸ» A complete introduction to API Testing
API testing includes testing APIs in isolation to ascertain if they meet the functionality, reliability, latency, performance, security, and other essential parameters.
API testing commonly includes testing APIs with JSON or XML payload sent over HTTP, HTTPS, JMS, and MQ. These are widely used data formats and networking/messaging protocols.
πŸ“Œ Types of API Testing

API testing is not a process that is carried out right away. It is divided into several categories which aim to test the API effectively so that the API can work in isolation, with integration, and produce the desired results to edge cases.
1️⃣ Unit Testing

- Testing the individual operations of the API by logically dividing them into units. Unit testing helps to identify imperfections in the early stages.

It typically includes testing each part of the code separately.
2️⃣ Functional Testing

- As the term suggests, Functional API Testing includes testing of all the functions in the codebase. It often uses unit tests as the building blocks.
3️⃣ Load Testing

- Load testing generally validates the functionality and performance of API under load. Load testing ensures whether an API will work as expected if multiple users are accessing the API concurrently.
4️⃣ Runtime error detection

- Runtime error detection can be performed manually or through automated testing. This testing includes monitoring an API by actually running the API entirely. It helps us to detect errors and exceptions and also prevent resource leaks.
5️⃣ Security Testing

- As the term suggests, this testing handles all the security aspects of an API, including external threats, validation, access control, and data encryption.
6️⃣ Penetration testing

- Penetration testing includes testing an API to find vulnerabilities in the system or codebase that attackers can exploit. It also includes testing functions that could be misused and test security assets that could be bypassed.
7️⃣ Fuzz Testing

- In this testing, we provide substantial random data as the input to test the reliability of an API. This random data is known as fuzz.

Fuzz testing ensures the API functionality in the worst-case scenario.
API testing is an essential aspect of API development. Thousands of developers will use your API in several applications.

Examining the reliability, functionality, security, resource leaks of an API is the most crucial thing to be considered at first.
With that being said, time to wrap up this thread.

Here are ten widely used HTTP headers:

πŸ”Ή Accept
πŸ”Ή Accept-Encoding
πŸ”Ή Authorization
πŸ”Ή Accept-Language
πŸ”Ή Content-Type
πŸ”Ή Content-Location
πŸ”Ή Content-Encoding
πŸ”Ή Content-Length
πŸ”Ή Content-Language
πŸ”Ή Cache-Control

Let's talk about them in a bit more detail πŸ§΅πŸ‘‡πŸ» Introduction to HTTP headers
Client and server can pass the extra bit of information with the request and response using HTTP headers.

HTTP headers are not case-sensitive.
The HTTP headers are divided into four categories:

1️⃣ Request headers: Client to Server

2️⃣ Response headers: Server to Client

3️⃣ Representation headers: Information about the body of the resource

4️⃣ Payload headers: Information about the payload data

Publish/Subscribe Pattern Based APIs

Let's try to know more about Pub/Sub design pattern and learn some facts about it.

πŸ§΅πŸ‘‡πŸ» Publish/Subscribe Pattern Based APIs
Publish/Subscribe (Pub/Sub) is an asynchronous messaging style used in serverless and microservices architectures.

With this model, messages are not sent to a specific subscriber but are instead categorized to be available to all subscribers of the category.
πŸ“Œ How Pub/Sub Pattern Based APIs Work

The main characteristic of Pub/Sub APIs is the existence of publishers and subscribers, as the name implies. Publishers categorize messages and those that are subscribed to a specified category receive that message.

There are three main characteristics of HTTP Request Methods:

1. Safe
2. Idempotent
3. Cacheable

Let's talk about them in this thread. πŸ§΅πŸ‘‡πŸ»
πŸ”Έ Safe

We can call an HTTP request method safe if it doesn't affect the server's state.
The safe methods request the server to send data without performing any modification to the original data. Hence safe methods accomplish read-only operations.
Even though they are read-only operations, they sometimes cause a change in server state; the server can update its statistics.

One thing to note here is that the safe methods never request the server to change its state.

There are 9 HTTP request methods:

πŸ”Ή GET
πŸ”Ή PUT
πŸ”Ή POST
πŸ”Ή HEAD
πŸ”Ή TRACE
πŸ”Ή PATCH
πŸ”Ή DELETE
πŸ”Ή OPTIONS
πŸ”Ή CONNECT

Let's talk about them in a bit more detail πŸ§΅πŸ‘‡πŸ»
HTTP request methods are the actions initiated from the client-side to perform certain actions.

These HTTP request methods are sometimes called nouns or referred to as HTTP verbs.
πŸ“Œ GET

The GET method is the most common of all these request methods. It is used to get the desired resources from the server.

The GET methods don't affect the state of the server.
