I want to do this, yet I can't. Here is my scenario and rational. I have an abstract class for test cases that has an abstract method called test(). The test() method is to be defined by the subclass; it is to be implemented with logic for a certain application, such as CRMAppTestCase extends CompanyTestCase. I don't want the test() method to be invoked directly, I want the super class to call the test() method while the sub class can call a method which calls this (and does other work too, such as setting a current date-time right before the test is executed for example). Example code:
public abstract class CompanyTestCase {
//I wish this would compile, but it cannot be declared private
private abstract void test();
public TestCaseResult performTest() {
//do some work which must be done and should be invoked whenever
//this method is called (it would be improper to expect the caller
// to perform initialization)
TestCaseResult result = new TestCaseResult();
result.setBeginTime(new Date());
long time = System.currentTimeMillis();
test(); //invoke test logic
result.setDuration(System.currentTimeMillis() - time);
return result;
}
}
Then to extend this....
public class CRMAppTestCase extends CompanyTestCase {
public void test() {
//test logic here
}
}
Then to call it....
TestCaseResult result = new CRMAppTestCase().performTest();
