Why Postman is the Ideal Automation Tool For API Testing

If you’re like most API testing experts, you spend a lot of time testing APIs. And if you’re like most API professionals, you don’t have time to waste. That’s why Postman is the ideal automation tool for API testing. With Postman, you can quickly and easily create, run, and monitor your tests. In this blog post, we’ll discuss the benefits of using Postman for API testing and show you how to get started.

Understanding what Postman is?

A postman is a powerful tool for developing and testing REST APIs. It comes with an intuitive interface, that allows you to create requests quickly, and then test, debug, and monitor them. Postman also has an impressive collection of prebuilt environments that can be used to simulate different scenarios and help developers write versatile code quickly. Overall, Postman is an essential tool for developers working with REST APIs.

A postman is a powerful tool that allows you to test and develop REST APIs quickly and easily. It comes with a user-friendly interface, that makes it easy to create requests, test them, debug any problems that arise, and monitor the requests as they are being processed by the API. In addition, Postman also has prebuilt environments that can be used to simulate different scenarios, which helps developers write versatile code quickly. All in all, Postman is an essential tool for programmers who work with REST APIs.

Top reasons why Postman is the best choice?

- Postman is easy to use. You don’t need any coding skills to get started with Postman. Just download the app and you’re ready to go.

- Postman is fast. With Postman, you can run your tests in parallel, which means you can get faster results.

- Postman is flexible. You can create custom scripts to tailor your tests to your specific needs.

- Postman is reliable. With its built-in support for variables and environments, Postman makes it easy to create tests that are both consistent and accurate.

Where does Postman Stand in the API Testing World?

Postman is the most popular tool for API development. And there’s a reason for that: it lets you easily create and test APIs by building out requests, analyzing responses, and monitoring calls — all without having to write your own code or leave the UI. But despite its popularity, Postman isn’t the only player in the API testing game. In fact, there are other great tools out there — this guide will cover some of your options.

This guide is broken up into two parts: first, we’ll look at Postman alternatives that provide similar functionality and offer the same level of quality and support as Postman; then, we’ll take a look at other tools that are dedicated to testing APIs. Let’s get started.

Part 1: Postman Alternatives that Provide Similar Functionality, Quality, and Support

1. Ready! API by SmartBear

SmartBear’s ready-made solutions and easy-to-configure tools make it a great alternative to Postman. The latest version of the product includes several tools for functional testing, including a test recorder that can record and generate API tests in minutes, an intuitive visual editor for building the code from tests, and a debugger to fine-tune those tests.

Additionally, Ready! API includes tools for load testing and performance monitoring for continuous quality assurance (or at least QA), as well as integrations with other software testing, development, and quality assurance software.

2. Insomnia

Insomnia is similar to Postman in that it’s a simple web app for making API calls without writing code or leaving the UI environment. It includes a built-in request builder with variables (and template support) for quick requests and responses, as well as a query builder for SQL-like querying, an HTTP client that supports multiple protocols (HTTP/2 and WebSockets), and integrations with popular third-party services like AWS, Stripe, Slack, Mailgun — and all of the integrations from Postman.

Insomnia does have some downsides: no native GUI, no built-in code generator, and limited third-party integrations (and they’re all different from the API integrations in Postman). Additionally, if you want to use it on your mobile device, you’ll have to pay for a companion app.

3. Paw by Lucky Orange Software

Like Insomnia, Paw is a GUI that makes it easy to build and test your APIs without leaving the UI or writing code. Where they differ is in the user interface: Paw has a native Mac app (with Windows, Linux, and iOS versions coming soon), integrations with popular third-party services like AWS, Dropbox, and Google Docs, embedding capability, and a built-in code generator.

Paw also offers test automation: it can generate tests from your API requests, run them through cloud infrastructure with AWS Lambda, and automatically refresh the page so you can keep tabs on how they’re performing over time.

Part 2: Other Tools Dedicated to Testing APIs

1. Postman App

Postman is the undisputed leader when it comes to API development and testing, just like how Microsoft Excel dominates the spreadsheet market — and for a good reason: its functionality-rich features, user-friendly interface, great documentation, helpful community support, excellent companion app (including a native Mac app), and sheer ubiquity make it the go-to solution for API development and testing. It’s no surprise that it has been downloaded over eight million times since 2013.

Plus, their company values are top-notch — they include transparency (using open source, speaking at conferences), building quality software (fast releases), and improving the lives of others in addition to making money. Still, like any tool in this space, it’s not perfect:

It doesn’t offer load testing.

While they have a lot of third-party services and integrations (which I talk more about below), they don’t come close to the number that Ready! API or Paw offer.

It doesn’t natively support creating tests — you have to use a paid companion app (or export into the format that can be imported into other testing apps) if you want to do so.

2. Postman API Monitoring by New Relic

New Relic is known for its fantastic SaaS monitoring software, and Postman API Monitoring is no exception to their quality: it’s a GUI-based monitoring solution that displays activity, performance, errors (complete with HTTP info), and response times as well as providing trace graphs.

The major limitation here is that it only integrates with the Postman app — so if you want to use any of the unique features of other testing tools, you’ll have to use another tool. But since a lot of testing can be done within the Postman app itself, that may not be a big deal for many users.

3. Runscope by Runscope Inc

Runscope is designed specifically with API monitoring in mind: it integrates with your APIs to provide tests, history, and performance monitoring as well as audit logging. You can also set up alerts based on specific metrics such as error rate and response time so you’re immediately notified when issues arise.

However, Runscope has a significant limitation: it only integrates with the Postman app. This means that if you want to use any of the unique features of other testing tools, you’ll have to use another tool. Still, if all you need is a monitoring solution and Postman app integration is sufficient for your team’s needs, this shouldn’t be an issue.

4. SoapUI by SmartBear Software

SoapUI is an excellent choice if you’re looking for a GUI-based solution that focuses on testing SOAP services. It offers load testing — with the option of integrating with JMeter and StormRunner Load — as well as mocking, performance monitoring, and test data generation (which can save time by automatically generating random values).

It does have a bit of a learning curve, though: although there is an online community with sample projects and documentation available, it doesn’t offer the same amount of support as other options — so if you need help getting started or completing more complex tasks (such as setting up API proxies), you may want to opt for another option.

5. Insomnia by Dave Smith

Insomnia is an online REST client that offers an intuitive interface, instant JSON validation and syntax highlighting, innovative keyboard shortcuts, and the ability to save Workspaces for later use — making it another fantastic option if you’re looking to create tests within its GUI instead of using a separate app, for example.

However, it does have some limitations: it lacks third-party integrations and doesn’t offer a native Mac application (although there is an unofficial Insomnia app that you can use if you want to test APIs on macOS). Still, these downsides may be outweighed by their benefits depending on your specific needs.

Conclusion

A postman is a renowned tool that can be used for various projects due to its effective traits like speed and advanced functionality…
