I would say you need a mix as they test different aspects of your application.
The Unit Testing module is great for testing the output of a microflow is correct. I use this mainly for utility sub microflows that don’t have any user interaction.
Selenium based tests are great for testing the front end of your application runs correctly. ATS is Selenium based, and is designed to work with Mendix. You can use other Selenium based testing tools such as Katalon Studio. This is cheaper, but does need more effort to get it work correctly with the Mendix app. This is usually around adding delays to give the page time to render before trying to interact with it.
SOAPUI and PostMan are great for testing services.
With these tools you will probably want utility microflows that can put the database into a known state before testing, and clear it down on completion. The Unit Testing module has some of this as it’s part of the platform, but other tools won’t have this ability and you’ll need to add it yourself.
Hope this helps.
What are your requirements? Selenium is a front-end test tool, but unit tests are more back-end related.
There is a very good Mendix add-on, named Mendix Application Test Suite (https://docs.mendix.com/addons/ats-addon/).
In my opinion it’s most practical to use Selenium to test your front-end flows and front-end logic. If you want to test your microflows too, you can use the Unit Testing module of Mendix.
I think you should add Cypress and Fitnesse to your short-list (asap).
Thanks for your Answer.
But ATS works on licensed version and I am more into the oss.
My purpose is to test a simple Mendix Application.
I focusing on that tool which integrate well with the mendix application testing purpose.
Please help me in selection of the tool from the option Selenium, Selenium IDE, SoupUI , TestNG and Unit Testing Module of Mendix.
Thanks for your interest
But currently I am comparing tools which are mentioned above only.
If you have any information about testing of Mendix that which tool will be better in the above tools then it will be very helpful for me.
Thanks and Regards,
So, in conclusion
SoupUI is not the best tool for Testing Mendix. It is for testing web services.
I can go with Selenium (for front-end (Web pages, and fields)) + Unit Module Testing (For backend (Microflows)).
If I concluded incorrectly please correct me.
