6 Essential reasons to Use postman/Newman Tool for API integration testing

5 Recent Innovations That Failed: Things that Product Leaders Can Learn From Them

You’ve created a fancy and new API that can manage all that you can toss at it. You went through hours doing manual testing to ensure your API works great. You’ve released your code and make a few updates. At the point, you need to go through hours testing once more. There must be a superior way. 

Here are 6 Essential Reasons to Use the postman/Newman Tool for API Integration Testing.

1. Make testing suites 

  • Postman helps you to make various integration testing.
  • It will guarantee your API is functioning well as required. 
  • Tests are running in a particular order alongside each test and have integrated next to the end of the last one. 
  • For every test, an HTTP request has created and attestations 
  • It has created in JavaScript and is then utilized to confirm the reliability of your code. 
  • If the testing has created in JavaScript, we can manipulate the past data in various ways. For example, making native variables and making loops to run the test. 

2. Store Data to Run The Tests in Various Environments

  • You composed your test assortment and everything works. 
  • You can run it over and over against your native environment and each test passes all the time. 
  • Yet, your local environment has arranged somewhat than a testing server. 
  • Postman enables you to store explicit data about various environments. Moreover, Postman helps you to embed the setup of the right environment into the test. 
  • This might be question parameters, a base URL, demand headers, and the body database for an HTTP post. 

3. Save the Data And Information for Different Tests 

  • Postman helps you to save the data from past tests into the worldwide variables. 
  • Those variables have used the same as environment variables. For instance, you have an API, which needs data received from a different API. 
  • You can spare the responses (or an element of the reaction, when it is a JavaScript) .
  • Also, you can use it as a major aspect of a post body, request header, or URL for the consequent API calls.  

4. Integration alongside Build Frameworks

For example, Jenkins using the Command-Line Tool Of Newman 

  • Postman is having a command-line-tool which also known as Newman. 
  • With Newman, it’s easy to run an assortment of tests from Newman’s command-line interface. 
  • This empowers to run the Postman testing on the system that doesn’t have a GUI. 
  • But it likewise enables us to run an assortment of tests created in Postman from the most build tools. Jenkins. For instance, enables you to execute commands inside the building work itself. 
  • Also, it helps you in the activity either failing or passing relying upon the test outcomes. 

5. Move Environments and Tests to Code Vaults/Repositories

  • With Postman, you can move and share the tests into various environments. 
  • It allows you to execute the testing process. This will integrate assortments in a “test” document and an “environment configuration” record. 
  • You can likewise export the test assortment and use a past file-sharing. This way will help you move from any environment. 
  • This additionally makes it easy-to-use code vaults/repositories tools. For example, SVN or Git to deal with the Postman testing and environment files.
  • Moreover, this will maintain the history of versions if you have to reign in changes. 

6. Instant Tests 

  • Whenever you think of some code, you will need to run it to ensure there aren’t any typos or bugs. 
  • Postman makes it simple to do that. Postman lets you compose a test without expecting to place it in an assortment, spare it, or have a backup. 
  • Make a URL request and see the consequence. 
  • Postman also parses the JSON database to make it somewhat simpler to read. 

At the End

Postman is an amazing asset for performing API integration testing with your API. It takes into consideration repeatable, dependable tests. So, this will automate the process and can use it in various environments. It incorporates valuable tools for the persevering database. Also, simulating how the users will be interfacing with the system or framework.
