This requirement can be verified by running test cases related to the "Cancel Trip" and "Book Trip" use cases. The "DiscountTravelOrderingSite" component satisfies the "Internet booking access" requirement, because it implements functions related to the requirement. In the example shown on the right, requirements are connected to model elements in order to express the model elements that refine, satisfy or verify them. This paper summarizes the functionalities of a module for the Modelio UML Case. Modelio provides a spreadsheet editor dedicated to requirements analysis, as well as graphical support of requirements modeling. Keywords: finite state machines, embedded systems, automatic testing. Requirements have properties and links to other elements (requirements or model elements). A requirement can appear in other diagrams to show its relationships to other model elements. A requirement can define a function that a system must perform, or a performance condition a system must achieve. These features make UML activity diagrams easy to understand and comfortable to use.Ī requirement specifies a capability or condition that must be satisfied.

For example, we see that the "Hotliner" partition has an actor icon, expressing that the partition represents an existing actor (called Hotliner). For example, in the case of a CPU, it takes into account its pipeline size, its cache meory, etc. Icons attached to an element express when they are connected (represent, typed by) to other model elements. Modelio makes it quick and easy to create activity diagrams through smart interactions: for example, just drag & drop an operation into an activity diagram to create an “operation call action” that is connected to the operation. We see here embedded partitions, behavior call actions, pins, received events and data stores. Modelio supports all the detailed features of UML2 activity diagrams. Partitions can be represented horizontally or vertically. Some examples of the viewpoints are the following: Application. They can be "autonomous" and represent a process, or represent the behavior of an operation. Modeling was done in Modelio using specific viewpoints developed for the PRESTO project. Activity diagrams are used to model business processes or the dynamic part of a model (an operation’s algorithm, for example).
