We are developing an application using Domain-Driven-Design(DDD).
We have to come up with Automated UI Test code.
The customer has used 3rd-party GUI Administration template (https://bootstraphunter.com/smartadmin-product.php) so that the GUI can be configured for the most part using the aforementioned 3rd-party tool.
For Automated UI Testing, I'm going to use NUnit with Selenium because I have experience using the said tools.
Sadly, the specifics about the Business-Side is left out.
In other words, customers has Not provided us with any use-cases or use case diagrams.
So far, a lot of the backend development(database stuff) deals with Generating New tables using Code-Generation Tools.
This basically suggests that the Customer is creating specific development tools for the application. As time goes on, I feel that the customer will configure the development tools to generate code and/or database tables.
Since a lot of the Business-specific requirements are vague, the customers communicates with our GUI development team to discuss how some module should be configured, but the problem is that I end up creating the Automated test code after the GUI module development is complete which is kind of pointless.
What steps should I take to make my Automated UI testing be significant in terms of usefulness in the development of the application?
