SoapUI Vs Postman: Two popular tools for API testing

SoapUI Vs Postman: API testing is an important part of software development, and there are several tools available for this purpose. Two popular tools for API testing are SoapUI and Postman. In this blog post, we will compare SoapUI vs Postman and look at some examples of how they work.

SoapUI

SoapUI is an open-source API testing tool that was initially designed for testing SOAP (Simple Object Access Protocol) web services. However, it can also be used for testing REST (Representational State Transfer) APIs. SoapUI provides a user-friendly interface for creating and running tests, and it also allows developers to write custom scripts in Groovy.

Postman

Postman is a popular API testing tool that allows developers to create and run tests for both REST and SOAP APIs. Postman provides a user-friendly interface for creating and running tests, and it also includes features such as test automation, collaboration, and monitoring.

Comparison

Now let’s look at some of the differences between SoapUI and Postman:

	SoapUI	Postman
Pricing	Free and open-source	Free and paid plans available
Ease of use	Can be complex for beginners	User-friendly interface
Scripting	Uses Groovy scripting language	Uses JavaScript
Collaboration	Limited collaboration features	Extensive collaboration features
Test Automation	Supports automated testing	Supports automated testing
Monitoring	Limited monitoring features	Extensive monitoring features

As you can see, both SoapUI and Postman are powerful tools for API testing, but there are some differences in terms of pricing, ease of use, scripting language, collaboration, test automation, and monitoring.

Examples

Let’s take a look at some examples of how SoapUI and Postman work.

We’ll start with a simple SoapUI test:

1. Create a new SoapUI project and add a new REST Request test case.
2. Enter the URL of the REST API endpoint you want to test.
3. Add any necessary headers and parameters.
4. Use the Assertions tab to define the assertions you want to make.
5. Run the test and view the results.

Now let’s look at a similar test using Postman:

1. Create a new Postman collection and add a new request.
2. Enter the URL of the REST API endpoint you want to test.
3. Add any necessary headers and parameters.
4. Use the Tests tab to define the assertions you want to make.
5. Run the test and view the results.

SoapUI and Postman are both powerful tools for API testing, and which one you choose to use will depend on your specific needs and preferences. SoapUI is a free and open-source tool that is ideal for testing SOAP web services, while Postman provides a user-friendly interface and extensive collaboration and monitoring features. Ultimately, the goal of both SoapUI and Postman is to help developers ensure that their APIs are working correctly and delivering the expected results.
