Accelerate your API Testing with Postman features
According to a survey conducted by SmartBear, more than 75% of software developers and testers said that they have increased their API testing efforts in the past year. Additionally, the survey found that nearly 70% of respondents used automated API testing as part of their software development process, further highlighting the importance of API testing in today’s software landscape.
One of the best tools for automating API testing is Postman. So let’s find out what Postman is, how it helps automate API testing, and how developers can quickly set up their API testing processes with Postman features.
What is Postman?
Postman is a powerful API development tool used by more than 11 million developers and 200,000 companies worldwide. You can install Postman as a separate, independent application on Windows, Mac, or Linux operating systems to operate inside the application. The tool helps speed up the development, testing, and API documentation. Tech specialists might also use Postman to make requests to backend applications while they are developing locally.
This type of testing supports a variety of assertion libraries that enable the creation of various assertions, such as verifying the response status code, response body, and response headers, and includes an intuitive user interface that allows developers to configure requests quickly.
With a built-in CI/CD pipeline integration that helps automate the testing and deployment process, Postman allows developers to set up continuous integration pipelines quickly and ensure that the code meets the expected quality standards before releasing it into production. It enables detecting any bugs before they become significant problems.
Postman features: Why use Postman for API testing?
The Postman API Platform includes several API testing features that help teams streamline their testing workflows and catch issues throughout the API lifecycle. With Postman, you can do the following:
Test API with pre-configured code snippets
Validate complex and end-to-end workflows
Teams can use Postman’s Collection Runner to link requests, run them in a particular order, and track test results. It allows teams to make tests that check complex, vital user experiences. This feature saves the team time and money by minimizing the need for manual tests.
Reuse API requests to test components
Teams can create and reuse Postman API requests across collections to speed testing. It permits ensuring that all components of the API are working correctly—while avoiding duplicate code.
Create custom assertions with Chai and Java Script
Perform API tests in parallel
With Postman, users run multiple tests simultaneously, which helps them quickly identify issues across their API endpoints without waiting for each test to complete sequentially.
Automate test executions on Postman Cloud
Postman enables users to set up tests to run at certain times and frequencies and receive notifications when tests don’t pass. This service runs on Postman’s infrastructure, meaning teams don’t have to worry about potential issues caused by unavailable local resources.
Execute API tests within CI/CD pipelines
Teams can use Newman or Postman CLI to run tests and collections in their Continuous Integration/Continuous Delivery (CI/CD) pipeline. Doing this helps maintain backward compatibility and stops new changes from breaking the production environment.
Monitor test results and troubleshoot bugs
Postman users can identify why a test has failed using the Postman Console. This tool lets them see details of each network call, including headers, certificates, requests, and responses. They can also track results from manual and automated tests and access reports for analyzing testing trends.
Create a dedicated testing environment
Users can store values in variables used in any request, such as the URL, headers, and body. This makes it easy to run automated API tests in a dedicated testing environment before releasing any changes to the production environment.
Incorporate Postman API tests into incident response workflows
The tool’s ability to connect with multiple systems, including Datadog, New Relic, and OpsGenie, provides teams with a comprehensive view of their systems, enabling them to make informed decisions and respond to incidents more efficiently.
What are the advantages of Postman?
