Is Testfully a Postman alternative? As the founder of Testfully, I receive this question quite often. In this article, I will make a fair comparison of Testfully & Postman to help you better understand Testfully and how it is different from Postman. By the end of this post, you will be able to decide whether you want to use Testfully or Postman for your automated API testing & monitoring or leverage both tools simultaneously.

Disclaimer: The below comparison is from the API testing & monitoring point of view. I have excluded some of Postman’s features that are not related to the API testing & monitoring. I assume you’re reading this article because you’re interested in finding an alternative to Postman for automated API testing & monitoring.

A comparison of apples & oranges

Testfully & Postman are two completely different products with some overlap, API testing & monitoring. Postman started as an HTTP client and evolved to a multi-purpose tool, a collaboration platform for API development (from which includes some API testing & monitoring capabilities. Testfully, on the other hand, was built from the ground up as an automated API testing & monitoring solution. If you are among Postman users looking for a Postman alternative, please continue reading as I will compare the two tools from this perspective.

No Coding Required Vs. Javascript

You need to know Javascript to use Postman for automated API testing, while Testfully offers a UI to set validations for the tests and does not require coding skills in general. Coding Vs. No Coding, does that matter? You might be asking. I think it does. Based on my experience as a TDD practitioner and software engineer, writing test code is repetitive, time-consuming, requires special skills, and requires good programming knowledge.

Testfully compared to Postman for API response validation

Testfully’s No Coding Required approach to API software testing offers the following benefits:

Environments & Configs

Environments are the names engineering teams give to deployed APIs; Production, UAT, Dev, Luna, and Staging are common environment names. Configs are values like access tokens, API Keys, API URLs that you will use in multiple tests and are different from one environment to another.

Both Postman & Testfully offer features to add multiple environments and config values. Still, the way you can use environments and configs in Testfully and Postman are different so let’s go through them one by one.

In summary, the Environment & Config features of Testfully integrates well with other elements of Testfully, makes your tests more maintainable and less fragile.

Test Multiple Environments

I believe that automated software testing (including APIs) starts while we’re building new APIs, extending existing ones, integrating with 3rd-party APIs, and continuing in staging & production environments. While Testfully offers a feature to use a test for validating API in different environments, Postman does not offer a solution, and it’s up to the user to come with a solution to test different environments using the same set of test cases.

Testfully’s multi-environment validation provides the following capabilities:

Let’s say we need to validate the response time of our endpoint in multiple environments, including “Production.” The expected response time in production is different from other environments. To implement this test using Postman, we should use the following technique:

Testfully, on the other hand, supports this feature out of the box.

Multi-step tests Vs. Single-step tests

Multi-step tests enable the verification of complex test scenarios that require more than one HTTP request. For example, to fetch a user’s profile, you need to pass a valid access token, and acquiring the access token requires an extra HTTP request. While Testfully offers test cases with multiple steps out of the box, Postman only offers single-step tests. As a result, what can be tested automatically via Testfully is broader than Postman. This feature is one of the main features that make Testfully a great alternative to Postman.

Testfully’s multi-step feature offers the following advantages:

In the below example test, we try to validate the correctness of the profile endpoint. While we can use the multi-step feature of Testfully to get a valid token and use it to fetch a user profile, Postman does not offer a solution. As a result, we need to update the token from time to time manually.

Simultaneous Test Execution

Speed matters. The faster you get test results, the more often you run them and rely on them to verify your API. Testfully supports simultaneous test executions while Postman runs tests one after the other when running tests. The Simultaneous Test Execution feature of Testfully enables you to get results for your tests way faster than Postman, and it shines when you have lots of tests or some of the endpoints are slow. If you’re concerned about the slowness of Postman when it runs tests, we highly recommend giving Testfully a try.

Test Result History

Historical test results are an essential component of any testing. They give you a clear picture of your API behavior at any given time. While Testfully stores test results (including request, response, and validations) in the cloud and make them available to all of your team members, Postman stores a limited subset of results in your computer and is available only to you.

Testfully’s time machine enables you to go back in time and explore the behavior of your tests at any given time. On the other hand, Postman does not offer any time machine capabilities at all.

API Monitoring

API monitoring is a feature that both Postman and Testfully offer. Using this feature, you can run tests in the background periodically, and the monitoring service notifies you when any of the tests fail. With that said, the two features provide different functionalities.

Test Runner

Both Postman and Testfully can run test cases on your computer. Testfully takes it one step further and gives you the option to run test cases on Testfully’s powerful server to gain the performance boost, something that Postman does not offer. As mentioned earlier, Testfully runs your tests faster than Postman, and that makes Testfully a great alternative to Postman.

Dummy Data

Using dummy input (email, ID, password, etc.) enables us to test APIs the way users use them. While both Postman and Testfully offer capabilities to generate random data, they work differently and offer different features.

While Postman offers a more extensive range of dummy data generators, Testfully offers a more extendable and customizable solution to match your needs.

CLI (Command-line Interface)

Testfully & Postman both offer a CLI tool that enables running test cases in the terminal. This feature becomes particularly useful when running tests as part of your CI/CD pipeline. Both tools look the same on the surface, but they’re very different in the way they work.

Comparison Table

FeatureTestfully CLIPostman
InstallationWorks on Windows, Linux, and MacRequires Node.js to run
Run a single testYes, By providing Test IDYes, you need to export a single test as a collection
Run a group of testsYes, By providing Collection IDYes, you need to export collection or make it publicly available
Run tests in parallelYesNo

We found that running tests using Testfully CLI is easier than Postman as you don’t need to export tests manually. Moreover, while it’s very likely to run outdated collections in Postman, it’s virtually impossible to run outdated tests in Testfully.

Testfully is laser-focused

While our friends at Postman offer solutions in different verticals, Testfully remains focused on nailing one single problem: Automated API Testing & Monitoring. As a result of our focus on one technical problem, Testfully offers many unique features or far more potent than the Posman, making Testfully an excellent alternative to Postman.
