We invite future students of the course "Java QA Automation Engineer" to take part in the open lesson on the topic "HTTP. Postman, newman, fiddler (charles), curl, SOAP. SOAPUI".
And now we suggest that you familiarize yourself with the translation of useful material.
Storing test data usually requires a data type that:
allows multiple properties to be declared;
has minimal or no behavior;
allows you to easily create multiple identical entities.
The objects almost meet these requirements. But then, to create several entities, it would be necessary to create several objects with a small number of properties and minimal behavior (or none at all). By minimal behavior, I mean a small number of methods. Basically, for every entity you need, you would have to create a new object, which is a waste of resources. Instead, you can use Enum
an object of a special type.
