Having witnessed numerous QA professionals manually migrating their scripts from SoapUI to Postman, I have observed that this straightforward process often leads to small but crucial mistakes. These small mistakes end up consuming more time than anticipated.
However, there's a smarter way to handle the migration efficiently and accurately, saving valuable time and effort in the process. By leveraging Postman's built-in features and integration with Swagger, the transition from SoapUI to Postman becomes a very smooth process.
Let's explore how to make this migration with ease, ensuring a smooth and error-free process.
Why migrate from SoapUI to Postman?
Moving from SoapUI to Postman offers many benefits that can significantly enhance your API testing experience and overall testing workflow. Here are some key reasons why you should consider making this move:
1. User friendly interface
Postman provides a more versatile and user-friendly interface, making it easier for testers of all levels to create and execute API tests with ease.
2. Reusability
Few features like environment variables, global variables and local variables encourages QAs to use reusability feature of Postman, even though this is also available in SoapUI but I personally prefer the way it is available in Postman.
3. Extensive Request Types
Postman supports various request types like json, graphql, xml, etc. making it more flexible and accommodating for different API testing scenarios.
4. Collaboration and Sharing
Postman's collaborative features allow teams to work together efficiently and share their API collections seamlessly.
Why not to migrate from SoapUI to Postman?
While migrating from SoapUI to Postman offers numerous advantages, there may be certain scenarios where sticking with SoapUI could be a benefecial choice. Let's explore some reasons why you might consider not migrating:
1. Existing project complexity
If you current project is too complex and heavy in terms of test case count, I would think twice them to migrate in Postman as one small mistake may break all the tests.
2. Groovy Scripting
SoapUI allows groovy scripting by which you can write more custom code which might not be possible in case of Postman. This is one of the key reason for me to decide which tool to use for Api testing. I would take a very informative decision to migrate the scripts from SoapUi to Postman solely because of this reason.
3. Project Specific Requirements and Learning Curve
If your projects have specific requirements that align perfectly with SoapUI's capabilities and are not essential in Postman, there may be no immediate incentive to switch.
Other than that make sure the entire team is comfortable in working with Postman.
How to migrate from SoapUI to Postman?
Create a swagger.json file in your system directory.
Right click on the SoapUI project and select Export Swagger/OpenAPI Definition.
3. In the next popup window, click Select All -> Provide the json file path which you created in step-1 in the Target File input field -> Ok
3. Import the swagger.json file to Postman. You will have your SoapUI project in Postman.
Pros of Migration
The migration process is effortless and can be done in a couple of clicks.
It creates the project skeleton in Postman similar to what you have in SoapUI. However, many key information might be missing post migration.
Cons of Migration
The import to Postman might not transfer all the information from the SoapUI project. For instance, properties defined in SoapUI won't be exported.
Any custom code you've written in SoapUI won't be automatically exported to Postman during the migration process.
Although Postman will create environment variables like {{baseUrl}}, the values assigned to these variables may not be defined or exported. This needs manual effort to define the values.
In summary, exporting from SoapUI to Postman may not offer significant value as it often requires reworking most aspects during the migration back to SoapUI.
