Define the test cases for the following system development: Oracle. (n.d.) Cruise Ship Management and Cruise Software.

Several test cases can be defined for this system. We name the most important top level cases and present the format using the login test cases as examples.

• Register
• Login
• View trips
• Search trips
• Book cruise
• Pay for cruise

Read Zhang & Budgen (2012). Which design patterns are used most commonly, and why?

Factory, Composite, Observer, and Visitor are most used in the studies.

The authors assume that the use of composite, although it needs some knowledge in recursion, its application does not produce any particular problems.

The most used patterns offered a good opportunity for triangulation, which is because they are studied using more than one form.
