Along with Test , Postman also provide capability to visualise your api response. It already have some predefined templates like bar graph, line chart and tables. Along with that you can inject your own template as well. Its very useful When UI have atomic design and you can visualise each component in postman itself.

Postman Test is also one of the best feature of Postman where it help testers and developers work together more effectively to ensure the quality, reliability, and performance of API endpoints throughout the development lifecycle. For Testers: Postman tests allow testers to automate the validation of API responses, reducing the need for manual testing and increasing testing efficiency. For Developer: Postman tests help developers validate the correctness of their API implementations, ensuring that the API endpoints behave as expected and meet the specified requirements

Postman Tests are JavaScript based tests within the Postman API development tool. They automate the validation of API responses, checking status codes, and response bodies... These tests ensure API reliability and functionality, providing rapid feedback to developers.

Postman provides built-in test scripts for convenience, or users can craft custom logic using the Chai assertion library. These tests play a crucial role in verifying the correctness of API responses and contribute to the overall quality assurance process. Additionally, Postman facilitates the generation of test reports and feedback, aiding in comprehensive evaluation. The platform's pre-request scripts further enhance functionality by enabling the setup of variables, parameters, or authentication procedures before dispatching API requests. This ensures that the requests are well-prepared and aligned with specific requirements, contributing to a more efficient and reliable testing process.

Postman tests are the code snippets that can be added to individual requests, collections and folders in a collection. We can add code snippets and then change to suit our test logic based on the scneario we are going to test and validate. In the Tests tab for a request, we can enter JavaScript manually or select snippets next to code editor. Tests can be executed after the response is received. The advantage here is that we can debug the tests using the log statements to ensure that we are asserting om correct data.

Postman Monitors serve as indispensable tools for streamlining API testing processes. They offer a comprehensive solution for continuous monitoring, enabling teams to proactively address issues, optimize performance, and maintain service level agreements. By leveraging monitors, organizations can ensure the reliability and scalability of their APIs while fostering a culture of efficiency and collaboration within their development workflows.

Postman itself is a popular tool for API testing, but if you’re looking to enhance your testing capabilities, you can consider tools like Newman (for command line runs), Postman Monitors (for automated scheduling), and integrating with tools like Jenkins or Newman Docker for continuous integration. Additionally, tools like RestAssured (Java), Insomnia, or Paw can complement your API testing toolbox.

In addition to automation, Postman monitors furnish detailed metrics, logs, and alerts pertaining to API performance. These include metrics on response time, error rates, and other key indicators. Such comprehensive insights empower users to identify and troubleshoot issues promptly, optimize API performance, and ensure compliance with Service Level Agreements (SLAs). By leveraging Postman monitors, you can proactively manage and maintain the health of your APIs, ensuring they meet the required standards and perform optimally. This feature is instrumental in establishing a robust monitoring system that aids in the continuous improvement of your API infrastructure.

Postman monitor is the best tool, which we can use to create an automation suites which can be scheduled and helps in monitoring the results and quickly helps us in identifying the underlying problems, like performance.

Postman monitoring helps to stay upto date om the health and performance of APIs. We can set up postman monitoring service quickly and integrate it with our API development pipeline. It is based on collections and monitors can be scheduled as frequently as every 5mins and will run through each request from the collection. This will validate responses and when test fail, we can automatically receive email notification and alerts.

Postman Mock Servers simulate APIs, allowing developers to test and prototype without a live backend. By generating dynamic responses based on defined examples or schemas, Mock Servers aid in frontend development and API testing. They offer a cost-effective and efficient way to validate client-server interactions before the actual backend is available.

Postman Mock Servers simulate the behavior of real APIs, allowing developers to test their client applications without deploying the actual backend. They provide a realistic environment for testing and debugging API interactions, helping to ensure the reliability and functionality of applications.

Configurability is a key feature, enabling the setup of mock servers to return diverse responses based on request parameters, headers, or body content. This adaptability facilitates comprehensive testing of API behaviors in various scenarios. A notable benefit is the ability to create an isolated testing environment. Mock servers permit developers to test APIs without impacting the production environment, ensuring a streamlined and secure development and testing process. This isolation accelerates development and testing cycles without compromising the integrity of live systems.

Postman Mock server is a tool that allows you to make API requests and simulate the corresponding responses. It benefits to evaluate your API during development and enable API infrastructure without having to write code. It allows developers to iterate more quickly. Mock servers can be used in the earliest design part of process instead of waiting for the endpoints to be built and deployed. This speed up reviews and defects and verify integration.

Postman simulated servers are simulated versions of your APIs that can help you test your API requests and responses without relying on actual back-end servers. You can create mock servers from your Postman collections or OpenAPI specifications and configure them to return different responses based on request parameters, headers, or body. Mock servers allow you to test your APIs in isolation, without affecting the production environment, and speed up your development and testing cycles.
