Software program and APIs undergo a number of levels, from planning, design, implementation, and testing to implementation. All these levels are necessary as they be sure that the product is compliant and free from errors and bugs.
SoapUI and Postman are well-liked API (Software Program Interface) instruments beneath improvement. APIs can be utilized in cellular or net functions as they bridge between the net server and the shopper aspect of the appliance.
APIs are available in numerous varieties akin to net, database, system, and file APIs. For instance, if you wish to add a climate forecast to your utility, you may get information from a climate API. Fee processors like Stripe and PayPal additionally provide the choice to make use of their API to allow cost processing.
This text introduces the function of SoapUI and Postman instruments in API improvement, discusses how you can use every device, and checks the similarities and variations to assist software program testers make knowledgeable selections.
What’s SoapUI?
SoapUI is a headless useful testing device for APIs. You should utilize SoapUI to check each SOAP and REST APIs.
SOAP (Easy Object Entry Protocol) providers are APIs that use HTTPS/HTTP because the transport protocol and Extensible Markup Language (XML) as the info format. SOAP APIs are beloved for his or her superior security measures, akin to digital signature verification and message encryption.
Representational State Switch (REST) or RESTful is a software program structure that describes how APIs ought to work. REST APIs should adhere to rules akin to unified interface, tiered system, statelessness, and code on demand.
SoapUI has these utilization eventualities;
- Useful testing

- Totally different options: You’ll be able to create, ship and save requests and responses from this mailman. You can even arrange these requests and responses into folders and collections.
- A central repository: Postman supplies builders with a central platform for storing, cataloging, and collaborating on API improvement. On this device you possibly can retailer and handle API documentation, specs, check instances, outcomes and workflows.
- Allows collaboration: The provision of Postman Workspaces permits staff leaders to group engineers into totally different classes. You’ll be able to create private, staff, associate or public workspaces relying on the character of the duties you wish to carry out.
- Integrates with different instruments: Postman has an API that’s straightforward to make use of. As well as, Postman integrates with key software program lifecycle instruments akin to GitHub, Jenkins, and Swagger. Among the featured integrations embrace AWS API Gateway, BigPanda, BitBucket Pipelines, and Azure DevOps, simply to call a number of.
Postman has a free package deal of tooling and collaboration instruments for as much as 3 customers and paid packages beginning at $12/person/month billed yearly.
SoapUI vs Postman

#1. SOAP vs REST APIs
SOAP and REST are the commonest API codecs beneath improvement. Luckily, SoapUI and Postman help each codecs.
Nevertheless, Postman was initially designed for REST APIs, however now helps SOAP API testing.
However, SoapUI was initially designed for SOAP APIs however now helps REST API testing.
#2. Debugging
You’ll be able to debug your code on Postman utilizing the Postman Console. This terminal reveals the small print of your requests and responses to find out the issues along with your code. You can even set breakpoints on the console to make debugging simpler.
SoapUI permits you to debug code utilizing the TestCase Debugging characteristic. You’ll be able to test your requests and responses by analyzing headers and physique texts. You can even set breakpoints to assist determine issues.
#3. Automated testing
Postman’s Assortment Runner can automate exams to run a given sequence. You can even schedule exams to run within the Postman cloud. You can even combine your runs with the Postman CLI and run your exams from the command line.
SoapUI’s Launch TestRunner characteristic permits you to write and run check instances. You can even programmatically create and check instances based mostly on numerous standards. SoapUI permits you to create and automate exams utilizing scripting languages akin to Groovy, Python, and Ruby.
#4. Cooperation
With each instruments, groups can effortlessly work on the identical challenge.
Postman has a Workspaces characteristic that enables staff leaders to manage staff member permissions. Workforce members can edit and touch upon challenge information instantly from Postman. The device additionally helps versioning to trace adjustments in challenge information.
SoapUI permits staff leaders to create shared tasks on the platform. Workforce leaders can then add members to collaborate on API testing. The device permits commenting and sends notifications at any time when a brand new change is registered on the platform.
Greatest practices for testing APIs
If you’re new to testing, you will not be positive how you can carry out such exams. Following are a number of the finest practices;
- Schedule your exams: It’s good to make certain why you want testing, what you can be testing and how you can do it. That is solely doable when you’ve got a transparent plan.
- Check with totally different information: You might be tempted to check your API utilizing solely the info you’ve got. Go forward and check it with invalid output and surprising information to see the way it will behave.
- Use totally different check strategies: When prototyping a quick API, chances are you’ll be tempted to rely solely on guide testing. Nevertheless, you can even strive others like load exams and safety exams to see how your API will behave.
- Automate your exams: Automated testing is your best option if you wish to carry out repeated exams.
- Doc your exams: A great API must be nicely documented. Doc all check instances and make it straightforward to seek advice from sooner or later.
- Spend money on steady enchancment: The exams you make as a first-time person will not be full. Preserve enhancing your exams, enhancing the standard of your API.
- Monitor your outcomes: An API isn’t a one-time factor. By monitoring the outcomes, you possibly can simply decide the efficiency of your API as soon as it goes reside.
