The main purpose of Postman is to test APIs by making HTTP requests and validating the responses.
The GET method is used to retrieve data without affecting the state of the resources on a server.
Postman allows users to store environment-specific variables in the Environment tab to customize requests.
Postman collections are stored in JSON format by default, which provides a structured way to manage requests.
Postman's Collection Runner allows users to execute all requests in a collection sequentially and automatically.
The Pre-request Script tab allows the execution of scripts before sending the request to prepare any necessary setup.
The Tests tab is used in Postman to write scripts for asserting responses by checking their validity and content.
Responses in Postman can be validated using test scripts written in the Tests tab for executing assertions.
Postman allows parameterizing requests using Environment Variables, enabling dynamic request data during testing.
A status code of 200 typically indicates a successful HTTP request, meaning the server successfully processed the request.
