Use Postman for API testing because it offers a user-friendly interface, supports automation, collaboration, environment variables, response validation, and detailed reporting. It also provides security testing capabilities, mock servers, and seamless integration with other tools, making it a versatile and efficient choice for testing APIs.

Postman is a tool that can be used without much training, both for manual and automation testing of APIs. It's easy to automate API tests and group them as a collection so you can chain the tests. You can share the collection across your team members, dev or QA, and integrate with CI/CD. I often use to to understand how various end-points work.

Postman is a popular and widely used tool for API testing, and it offers several benefits that make it a preferred choice for many developers and QA professionals. Here are some reasons why you should use Postman for API testing: 1. User-Friendly Interface: allows users to easily create, organize, and execute API requests 2. Request Building and Parameterization: Postman simplifies the process of building and sending API requests. 3. Collection and Environment Management: organize your API requests into collections, making it easy to manage and group related requests 4. Automation and Testing Workflow 5. Testing with Variables and Data Sets 6. Assertions and Test Scripts 7. Collaboration and Sharing 8. Integration with CI/CD

Postman is an excellent tool for API testing due to several reasons. Firstly, it provides a user-friendly interface that simplifies the process of sending requests and analyzing responses. Secondly, it offers a wide range of features, such as automated testing, request chaining, and environment variables, which enhance productivity and efficiency. Additionally, Postman allows collaboration among team members, facilitating seamless sharing and documentation of API endpoints. Overall, Postman streamlines the API testing process, making it an indispensable tool for developers and testers.

Postman is a great and one of most famous API testing tool popular among developers and QA s. it has more flexibility of maintaining API collections for testing. As an example when you have OAuth endpoints for Authentication and Authorization then easily you can do end to end API testing with postman integrations. it can share your API response variables in to another API call easily. You can group and maintain endpoint collections as well. Also Postman has flexibility of API test automation and CI/CD integration with newman or Postman CLI. Postman has flexibility to maintain test data and environmental variables. You can create a team workspace and share the collection with your team (could be install in cloud)

Open Postman and create a new request by selecting the request type (e.g., GET, POST) and entering the request URL. Add any necessary headers, parameters, or authentication details in the respective sections. Click "Send" to execute the request and view the response. Check the response status, headers, and body for the API's output. Utilize features like collections to organize and save multiple requests for easier testing and management. Use Postman's testing capabilities to write scripts for automated tests, validations, and assertions on API responses.

You can create collections for each and every service (support SOAP, GraphQL, REST protocols and etc) and maintain API endpoints inside the collections. When your collection APIs need to reuse the response data from another API then set up "global environmental variables" to pass data. Postman has pre request script to process these data (update, change) before passing to another request. Postman Test tab support to to assert the responses for testing. You can call an API easily using Url endpoint, http method, headers, authentication data, request body if need and just send the request. then assert the response using java script coding inside test tab.

Before testing an API, It is imperative to know URl, endpoints and API's behavior from API document like swagger. Once all these prerequisites met. We can happily test API. First and foremost thing we have to do is select request type. If necessary provide details about request body, authentication details like bearer token, set and unset environment, collection level variable throughout run. Configure data driven testing for API testing. Once all these things ready click on run button and check read the response body. Validate the response details are as per the API behaviour or not. Export the collection and make it feasible to run via CLI, CI/CD pipeline, Jenkins etc.

Organize your APIs by creating collections for different services, accommodating various protocols such as SOAP, GraphQL, and REST. Maintain each service's API endpoints within its respective collection. To facilitate data reuse between different APIs, leverage "global environmental variables" in Postman. These variables can be manipulated using pre-request scripts, allowing you to modify or update data before passing it to subsequent requests. Utilize the Test tab in Postman to implement response assertions for thorough testing. This ensures that the API responses meet the expected criteria. Simplify API calls by providing the URL endpoint, HTTP method, headers, authentication data, and request body as needed.

1. Installation: Desktop or Web Version 2. Request Creation: URL, Method, Headers, Parameters, and Body 3. Collections: -Grouping Requests 4. Runner Feature: Executing Requests 5. Response Verification:- Tests Feature 6. Debugging:- Console Feature

Its always our favourite API testing tool due to the nice and easy user experience and the performance. If your organization dont need complex automation suite or only have limited resources to the automation then Postman is a great tool to maintain an end to end API automation suite. Having CI/CD support also a great advantage

The major advantage of Postman is interactive interface which is easy to understand. It supports most of the Operating systems and it can be integrated with CI/CD pipeline. It provide the Assertion and verification and a widely used tool for testing different HTTP methods. Also, good documentation is available which helps easy to understand and test API's.

Users can organize related API requests into collections. Postman also supports the creation of different environments, enabling developers to switch between sets of variables easily. This is useful for testing APIs in various environments, such as development, testing, and production.

Postman has many benefits such as- 1) user friendly interface 2) Automation Testing possible 3) Api collections can be shared easily. 4) Scope of performance testing 5) Integration with other tools and CI/CD pipelines.

My perspective is that Postman faces challenges with complex end-to-end (E2E) test scenarios involving intricate test data. Unlike code-based frameworks, Postman's handling of dynamic, data-driven tests is less flexible, making it hard to model complex interactions and data states. This limitation becomes more pronounced in large-scale projects where the volume of test cases and data variability increases. Here, code-based solutions offer superior reusability and maintainability. They allow for better abstraction, version control, and integration with CI/CD pipelines, ensuring scalable and efficient test management

1. Managing Large and Complex Collections: Handling extensive collections of requests and tests, particularly in dynamic and rapidly evolving project. 2. Integration Complexity: ntegrating Postman with other tools and platforms, such as CI/CD pipelines. 3. Cost for Enterprise-Level Testing: For large-scale or enterprise-level API testing, the cost of Postman's advanced features and services,

One of the main challenges I faced was setting up cookies however in the new versions there are many add on plug ins like syn cookies helped to set up correct cookies out of millions of parameters. Another struggle is integration with CI/Cd

Some of the key challenges of using Postman for API testing: 1. Maintaining large, complex collections with hundreds of requests becomes cumbersome and can be prone to errors. Modularization and organization strategies are required. 2. Repeating the manual tests can be time consuming, hindering productive scaling, especially for frequent regression testing needs. Automated scripts help. 3. Single, integrated environment limits team-based collaboration. Lack of role-based access and visibility is an organizational problem. 4. Lack of API lifecycle features like design, documentation generation, mocking, and monitoring support as in dedicated API testing platforms. 5. Inability to fully emulate and model production complexitylimits realistic

Postman is definitely useful, but it also brings some challenges. One of them is its limited capabilities for automated testing. This can be a hurdle for big projects needing complex, multi-step tests. It also lacks support for certain data formats. E.g., XML is not as well supported as it could be. This can be a problem if your API relies heavily on XML structures. Another issue to consider is reporting features. It does have some built-in reporting, but it's not very thorough or customizable. To get more detailed reports, you need to use its companion tool, Newman, to create custom ones. Lastly, it lets you create code snippets in many programming languages. However, the generated code usually needs manual changes before you can use it.

o effectively address the hurdles encountered in utilizing Postman for API testing, employing strategic approaches can significantly enhance workflow efficiency. Utilizing naming conventions, descriptive annotations, and comments facilitates the organization and documentation of requests and tests, thereby streamlining navigation and comprehension. Leveraging variables and environments enables the centralized storage and reuse of data across multiple requests and tests, fostering consistency and scalability. Integration of scripts and tests injects logic and validation capabilities, ensuring the accuracy and reliability of test outcomes.

Overcome Postman API testing challenges by investing time in mastering complex scenarios, exploring command-line options, and diligently organizing large collections. Leverage Postman's learning resources, adapt to updates, and consider the paid version for advanced features. Regularly review and optimize testing processes to enhance efficiency.

Postman is primarily designed for functional testing, and its capabilities limited compared to specialized tools. Consider integrating with external sources using tools like Newman or Jenkins for advanced automation, dedicated performance testing tools like Apache JMeter for scalability, and specialized security testing tools.

Version Control: Consider using version control systems (such as Git) to track changes in your Postman collections. This is especially useful for collaboration and managing updates across the team.

When working on automating tests in postman follow naming conventions for variables (collection & environment) to avoid confusions. Spend enough time and leverage documentation option in postman to document the changes and tests added. Integrate communicators like slack to post the results to get immediate attention on false negatives and update the script.

Para equipes que não possuem incentivo da empresa para automatizar testes e vivem com alta demanda para os testes manuais, utilizar o postman como seu braço direito e uma estratégia eficiente para os testes, seja para gerar massa de teste automatizados em segundos ou até mesmo rodar testes regressivos para aqueles cenários críticos para o sistema.

Postman I am using since last 5 years and it's been very handy tool when it comes to test the network API's It helps me to test the vulnerabilities even and also helps to report them for resolution so that data is safe

You can use different tools for API testing, you can write your script, or use CURL or different sniffers. The question is: Why should you test API separately? -Early detection of issues: API testing can catch most errors reducing the overall time and cost of fixing them -Focus on business logic: test the business logic of the application without the need for the UI -Efficiency: API testing is generally less time-consuming than UI testing == a more efficient approach -Integration readiness: You can ensure that API is functioning correctly !!-Security: APIs often handle sensitive data and need to be secure. Testing APIs separately can help identify any security vulnerabilities before they are exposed through integration with other systems
