What is Class in TOSCA ?

• Class is a template for a particular type of entity. 
• Classes are used to define the properties, attributes and behaviors of different components.
• When you drag and drop a Class onto a TestSheet, Tricentis Tosca creates a Class reference that allows you to use the Class Attributes and Instances in your TestSheet.
• If you modify an Attribute or Instance in the Class, Tricentis Tosca automatically updates all Class references,  Conversely, If you make any modifications to a Class reference, the system automatically changes the corresponding Class.
