Postman Testing

Postman Testing is been the automation software testing tool which is an application programming interface(API) platform used for creating, testing and designing the documents of APIs. This is the simple graphic user interface for sending and viewing HTTP requests as well as responses.

Application programming interface which is also called as API is the software which acts as the interface between two apps where as HTTP is the collection of data on the world wide web it might be graphic images, text etc.

Web users make use of HTTP as they open web browsers. Lets consider an example: user or the browser when enters HTTP requests to the server, then the server returns as the user response. This response which consist the request status information has requested material as well. Most widely used HTTP methods are GET, POST, HEAD, DELETE.

When we make use the Postman tool for the testing, one has to write any HTTP client codes instead of that. We can build the test suites called as collections and that allow postman interact with the API.

This has the potential to make variety of HTTP requests like GET, PUT etc which will change the API to code for the language like JavaScript and also python.

Application programming interface is the software which will act like intermediator for two applications which will communicate with each other. We can make use of applications like twitter, facebook etc.

Postman is based on wide range of user friendly power tools. Following are the reasons for postman tool:

1. Ease of access: this can be made use of anywhere after its been installed and the postman into device by simply logging into the account.
2. Use collections: this will allow the users to build collections for the API where every set will create multiple requests which will help to organise the test suites.
3. Test development: this can be make use for the test checking for the verification of successfully HTTP responses which will be added to all API calls
4. Automation testing: this will perform in several repetitions by making use of the collection runner which saves the time for repeated tests
5. The design of different environments which results in less replication of the tests like one can use the same collection for the different settings
6. For debugging the tests the postman will be helping to track what kind of data is been retrieved
7. We can also take the collections which will enhance by sharing of the files. We may also make use of direct connection to share the collections
8. It will support continuous integration. 

As the number of web and mobile applications is increasing, the importance of API testing is been growing. Postman platform includes set of tools which accelerate the API lifecycle design, testing etc.

Postman API client is the main foundation tool for the postman which allows us to explore debug and test out API. This will detect the language of the response, links which makes inspection easy.

By making use of the API client it will be able to identify the requests into postman collections which helps us to organise our requests for utilise so that we don’t spend time in building everything from scratch.

We can design API using postman by making use of open AI, RAML etc,. It make s easy to work with the specification files of any size, validates the specification files of any size, it also generates the postman collections for multiple stage of API lifecycle like mocks, documentation tests, monitors.

Postman is also used for the writing the functional tests, integration tests and more. Postman node js.based which consists support for the patterns and libraries which use to build tests quickly.
