5 Recommendations For Testing Web APIs With Postman

There are several important recommendations for testing web APIs with Postman. Notably, Postman can make it easy for developers to create, share, and test APIs. Indeed, they can create and save HTTP/s requests. Plus, they can use APIs repeatedly without having to remember the exact endpoint, headers, or API keys. As a software developer, you need to know the best practices for testing web APIs with Postman. This way, you can increase efficiency and reduce tedious steps in your execution process. Read on to discover some of the top recommendations for testing web APIs with Postman.

Write Test Scripts

First, you should write test scripts when testing web APIs with Postman. Indeed, you can create individual JavaScript test scripts to validate your API responses. If you’re new to writing test scripts, Postman provides code snippets with validations you can use. For example, look at response time and response code to get a template for your own script. In addition, you can write pre-request scripts to run before you send your request. Here, you might create a Postman query to an API and receive a JSON response. Then, you can write tests for your fitness technology and other apps to validate the response and check outcomes in the Test Results response tab. Definitely, write scripts to test your web APIs with Postman.

Organize Tests Into Folders

Next, you should organize your tests into folders when testing web APIs with Postman. To get started, save a group of API requests Postman Collections. Once they’re saved, you can create a top-level folder for each of your API’s resources such as users, orders, and products. Inside this folder, make a second-level folder for test suites on each of those resources. For example, you can make one for “Start a new order,” “Edit an existing order,” or “Cancel orders.” If you only need simple tests with one API call, you can create requests directly under your test suite folder. For more complicated tests, create a third-level folder for workflows. Absolutely, organize tests into folders to differentiate your requests when testing APIs with Postman.

Utilize Bulk Edit Features

In addition, utilize bulk edit features to streamline web API testing in Postman. Within the Header and Param section, you can select the Bulk Edit option in the top right corner to see a list of headers and params in text format. This way, you can copy all the text and move to your new request. In the same section of your new request, select Bulk Edit again. Then, paste the text within the section. From here, you can click Key Values, which should have replaced the Bulk Edit option. In this menu, you should see all of your headers and params in the table format. Using this feature, you can save time from manually updating headers and parameters in your collection requests within your HP enterprise system. Undoubtedly, utilize bulk edit features as you test APIs with Postman.

Test Common HTTP Requests

Moreover, test common HTTP requests when running APIs in Postman. For example, you can use the GET method to retrieve information from the server using a given URI. In addition, many developers use the POST request to send data to the server. Typically, you can use this to send customer information and file upload using HTML forms. Plus, try the PUT request to send data to a server or update a resource. Notably, this replaces all current representations of the target resource with updated content. Of course, you can also use PATCH requests to update partial resources. This is great when you only need to update one field of a resource. Indeed, PUT requests may utilize more bandwidth. In short, test common HTTP requests when testing APIs in Postman.

Use The Collection Runner

Using the collection runner is another recommendation for testing web APIs with Postman. Click “runner” and select your folder underneath your collection. Next, you can set the iterations or amount of times the same requests run. For instance, an iteration set to 4 will run each request 4 times. Here, you can start with 2 and make changes as needed. In addition, set the delay or wait between your iterations. For example, a delay of 15ms has Postman wait 15ms before running the next iteration. Ideally, you should set your delay to 5ms for the right time between. Now, you can click “Run MyFolder” to visualize the available test results. Of course, use the collection runner to test web APis with Postman for robotics AI companies and other types of apps.

There are several important recommendations for testing web APIs with Postman. First, you should write test scripts in JavaScript using Postman snippets. Next, organize tests into folders when testing your web API. In addition, utilize bulk edit features to manage headers and params. Moreover, test common HTTP requests depending on your data retrieval and send needs. Furthermore, use the collection runner to run all the requests in a collection at once. Follow these recommendations for testing web APIs with Postman.
