Testing

14. During which software development phase would you define the user interface classes?

• A. Object design

• B. Problem analysis

• C. Maintenance

• D. Architectural design

• E. Project initiation

15. What is the definition of cohesion?

• A. To measure the dependency between objects

• B. To measure the degree to which the elements of an object support the same purpose

• C. To assemble a set of part objects to create a new whole object

• D. To create a shared definition for common properties of a set of similar objects

16. A scenario is

• A. A single user session form beginning to end

• B. A single activity from start to end

• C. A single logical path through a use case

• D. A single normal or exception flow of events

17. Scenarios can be identified in an activity diagram by

• A. Selecting a set of related activities

• B. Following the triggers from one activity to the next until you reach a stop or return

• C. Following the triggers from one activity to the next until you reach a decision branch

• D. Selecting each loop and each branch of each decision

18. What elements make up the description of an association?

• A. An association line, multiplicity, an association name, and constraints

• B. An association line, name and/or roles, and optionally constraints

• C. An association line, multiplicity, name and/or roles, and optionally constraints

• D. An association line, multiplicity on both ends, and name and/or roles

19. The purpose of the interaction diagram is to

• A. Discover and define the communication between objects

• B. Discover and define the sequence of interactions between objects

• C. Discover and define the interfaces on classes

• D. Discover and define the attributes that define an object

20. If an object does not own the parameters it uses in an operation, then where do you look?

• A. In the class diagram for a class that should own the data

• B. In the responding object

• C. In the sending object

• D. In other sequence diagrams that use the same type of parameters

21. When you define the events in the sequence diagram, you have to draw the event from a sending object to a receiving object. What do you do if there is no direct association between the classes that these objects belong to?

• A. Sequence diagrams define only the required interfaces on the destination object, so they do not have to include the complete path to the object.

• B. Add an association between the two corresponding classes so that the two objects can communicate directly.

• C. Find another object to handle the event because the object you picked is not available to receive the event.

• D. Refer to the class diagram to identify the path that the communication must follow. Add the intervening objects to the sequence of events.

22. What two class elements are required in your model to manage the state of an object?

• A. One or more attributes that describe the condition of the object and corresponding operations to maintain the attribute values

•  B. An attribute that describes the state of the object and the domain of valid values that can be assigned to the status attribute

•  C. One operation for each way that the object's state can be changed and a corresponding attribute for each type of change.

• D. One or more attributes that describe the object's responsibility and an operation that manages the modifications to the responsibilities.

23. How do you change the model to improve cohesion and coupling when an object appears to have too much responsibility?

• A. Reassign responsibilities to an existing class or split the class into two or more classes with a narrower purpose.

• B. Find a design pattern that has been tested for that kind of situation.

• C. Encapsulate the object to hide the complexity from other objects.

• D. Define a separate interface for each responsibility. The new interface will delegate the responsibilities to the original interfaces
