Hi Guys,
Postman, I hope many of you heard this name If you are in the software engineering field. In today’s article, I will be discussing about it.
Before moving further, I am assuming that you have basic knowledge of postman and you know the installation of a postman on your machine. If you are completely new to postman then I would suggest reading about it a bit before taking these tutorials.
Let’s Start 🙂
Whenever we start any project in postman we do use following hierarchy.
Workspace -> Collections -> Folders -> Requests
Workspaces – Postman workspaces allow real-time collaboration within and between teams with built-in version control. Workspaces act as a single source for Apis, collections, team collaboration, mocks, monitors, test cases etc
Collections – It is a group of APIs, Within a collection, request are distributed in folders. You can create any number of folders within a collection
Environment – Environment is a key-value pair collection. Sometimes in a project we do have multiple environments and based on that we make API calls. Like Development / Production environment. Same way in postman we can configure multiple environments for handling the request for dev/QA/production etc.
Request – Postman supports various kinds of HTTP requests like GET, POST, PUT, DELETE, etc.
Request supports multiple options like:
Params – It is used to pass query parameters. That we generally do when making GET, PUT, or DELETE request.
Ex: /api/v1/bootcamps/5e9c9d895244c131350ca15a
Authorization – Postman gives multiple options for authorization. For instance, Bearer Token, OAuth 1.0/2.0, AWS Access tokens, etc.
Headers – In headers you can pass multiple values like Content-Type, Cookie etc
Body – It supports multiple options like
- form- data
- x-www-form-urlencoded
- raw
- binary
- GraphQL
Pre-request Script – This is useful when you have to make a few configurations before firing the request. Then you can make use of script mode.
Tests – As the name indicates, It is used to write test cases for APIS, Like if you want to write a test case to check if the response time of an API is taking less than 1 sec.
Example:
pm.test(“Response time is less than 1sec”, function () { pm.expect(pm.response.responseTime).to.be.below(1000);});
That’s it for now, In the tutorial we will setup our own environment in postman.
