I did not use SoapUI and can't compare them. But, Postman gave results my team needed, that's why we did not test any other software. Runs simple, gives instant and exact results.
Chose Postman
Postman has pros and cons both and keeping them in mind we are using multiple tools to leverage our Services, integration, automation, and testing needs.
Some of the above mentioned tools have better automation or complete framework implementation capabilities. Having all the …

Selenium is way better than those two as it's free and has great community support.
Chose Selenium
The first obvious thing is Selenium, an open-source tool, and it has a wide-open community for support. Well, on the other hand, Silk Test is a paid tool. With the combination of different tools in the market, we can build a solution for Web and Mobile based automation using …

Postman
Postman is very good for easy entry into testing. Thanks to snippets it is easy to use, but also provides a lot [of] possibilities for testing thanks to the in-line editor. Easy to use on multiple environments (versioning) thanks to sets of environment variables. The Collections view can get very full with time and it is not possible to reuse or link requests so that they have always been copied and maintained manually for each copy if changes have to be applied.

When you have to test the UI and how it behaves when certain actions are performed, you need something that can automate the browsers. This is where Selenium comes to the rescue. If you have to test APIs and not the frontend (UI), I would recommend going with other libraries that support HTTP Requests. Selenium is good only when you have no choice but to run the steps on a browser.

Pros
Postman
  • It has opened a door for me to explore more out of it, as it is associated with so many APIs that I never felt any difficulty in finding the right API template, which are well organized and easily available.
  • It is very secure to use and provides great services which are user-friendly.
  • Due to this software I have got rid of the excessive emails and the slack channels, Now I am using my own private API and even it give me an option to produce my personal Postman’s API Builder from its Private API Network and this features has shared my excessive workload.

Cons
Postman
  • Wherever you need to automate tests that involve database verification or rely on data from databases, Postman is less suitable.
  • Postman's disc usage is extremely high, and it occasionally causes the computer to fade.
  • It doesn't have the ability to generate random data. To achieve randomness in my tests, I've been working around scripts.

  • Selenium is pretty user-friendly but sometimes tests tend to flake out. I'd say roughly one out of twenty tests yields a false positive.
  • Selenium software cannot read images. This is a minor negative because a free plug-in is available from alternate sources.
  • Slowness may be a minor factor with Selenium, though this is an issue with basically any testing software since waiting on a site to execute JavaScript requires the browser to wait for a particular action.

We love this product mainly because of its high customization abilities and the ease of use. Moreover, its free and can be learned easily through online communities and videos. The tests are more consistent and reliable as compared to Manual tests. It has enabled us to test a large number of features all in one go, which would have impossible through manual tests. The reports generated at the end of the tests are really helpful for the QA and the development teams to get a fair view of the application.

Usability

I think from a non-technical perspective there are a few things that could be more clearly labeled to better understand what is being asked for or where to add certain parts of the request.

As I mentioned earlier, the reason I use Selenium is because there is a fairly widespread community of users, and user support services are at a good level. because the application is open source, it works on many platforms (Windows, Linux, IOS) without any problems. In addition, it gives us a lot of options for writing functional tests. For errors that we receive through the application, we can easily find the reasons for errors in the forums.

Postman
There is a lot of in-depth documentation for Postman available online, including detailed guides with screenshots and videos. They provide example APIs for new users to explore while learning how to use the tool. Generally, bugs in the client are quickly addressed through frequent free updates. Community and professional support options are available - most of the time, the free/community level support is adequate

Selenium does not have technical support available easily. You have to go through forums to get the information you need. However, there are excellent forums out there that make it easy to troubleshoot. The open-source flexibility makes it difficult to have dedicated support.

We did everything we needed to use it. Now we can execute our tests on different operational systems and browsers running few tests simultaneously. We also implemented Appium framework to execute our tests on mobile devices, such as iPhones, iPads, Android phones and tablets. We use SauceLabs for our test execution and Jenkins for continuous integration.

Previous to using Postman, I would either use browser tools directly, or write an in-house tool to send requests. Postman eliminates that need while providing a much better experience and more features. At the base level, Postman is as simple as typing in the address as you would in a browser. Authentication can be provided simply as well.

At the time of adoption, there were not many other alternatives that were even close to being competitive when it comes to browser testing. As far as I know now to this day, there is still little competition to Selenium for what it does. Any other browser-based testing still utilises Selenium to interact with the browser.

Return on Investment
Postman
  • Postman is free (although there's a paid tier that offers more features) so using it for testing APIs comes with little to no risk (besides learning curve).
  • The learning curve is a little steep for non-developer users, but developers should find it easy to pick up and use right out of the box, so to speak.

  • There hasn’t been a downside to using it yet other than we’ve got to update the programs we create for each change.
  • This has saved us hundreds of hours of manpower by allowing our automation engineer to rapid fire tests.
  • We are able to screenshot and save entire sites before and after launch with a program the automation engineer created
  • We can compare large volumes of data against data in excel docs with a program created using Selenium
