- This API provides sentiment analysis, stemming and lemmatization, part-of-speech tagging and chunking, phrase extraction, and named entity recognition.
API testing is performed to test whether a particular API meets some pre-defined parameters or not.
Let's talk more about API Testing π§΅ππ»
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.
Let's try to know more about Pub/Sub design pattern and learn some facts about it.
π§΅ππ»
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.
π 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. π§΅ππ»
πΈ 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.
