A project skeleton for implementing the Composite pattern and the Observer pattern (and some sort of Template Method pattern) based on tests using JUnit4.
This project is a Maven project, i.e. it uses the standard Maven project structure that your IDE should understand
when you git clone it. The provided Maven POM includes the JUnit4 dependency.
Both the implementation and the tests are in Java package is.hi.hbv202g.ass9,
but in the usual separate Maven src directories:
-
src/main/java:is.hi.hbv202g.ass9.composite: Your implementation of the Composite pattern has to go there. Choose class, interface, and method names so that they fit the provided test cases.is.hi.hbv202g.ass9.compositeObserved: Your implementation of the Composite pattern that is combined with the Observable patterns has to go there. Choose class, interface, and method names so that they fit the provided test cases.is.hi.hbv202g.ass9.compositeObservedTemplateMethod: Your refactoring of the above patterns inspired by the Template Method pattern.
-
src/test/java: (each package contains anAlltestsclass that collects all the test cases for the respective package in one test suite, so that you can execute exactly only the testcase of the package that you are currently implementing),is.hi.hbv202g.ass9.composite: Test cases testing a composite implementation.is.hi.hbv202g.ass9.compositeObserved: Test cases testing an implementation of a composite where the leafs are observed by the composite implementation.is.hi.hbv202g.ass9.compositeObservedTemplateMethod: The same test cases for testing the refactoring of the above patterns inspired by the Template Method pattern.
-
mvn compilecompiles all implementation classes. -
mvn testruns all test cases (i.e. all classes with a name that either starts withTestor ends withTest,Tests, orTestCase). As long as you have not finished implementing all packages, it is better to use the IDE to run individual test cases or package-level test suites.
