Generic Testing
Generic testcase is an Umple testcase that is defined as generic. This allows you write a test template that has access to the metamodel in order to propagate the template against a number of elements those match a certain pattern. For instance, you can write a generic test that can be generated for each attribute that is string and has a certain prefix 'studentXXX' or a suffix such as 'XXXId'. You can also use regular expression to match attribute name. We can this a fix in the template. Currently, generic tests can be generated for: attributes, methods and associations. Attibutes can be matched using name and type, methods can be matched using name and exact order of parameters and association are matched based on the type of associations and given specfic fixes to handle association variable propagation.
Example
class Student {
String studentId;
nameMemebershipId;
address;
studentAge;
generic test checkifLogged(String attribute.regex(\w*Age)){
Student st1 ( "S1425", "John", "Ottawa",20) ;
String valueToCheck = st1.get<<attribute>>();
assertTrue(valueToCheck > 18);
}
}

class Calculator{
1--* Number;
0..1->* Controller;
generic test checkifLogged(0..1->* association){
Calculator c1 () ;
Number n1(c1);
Number n2(c1);
Controller cn1();
Controller cn2();
c1.addNumber(n1);
c1.addNumber(n2);
c1.addController(cn1);
c1.addController(cn2);
String numberInList = c1.numberOf<<association.toSingular()>>s();
if(c1.numberOfNumbers() > 2)
{
assertTrue (numberInList > 2);
}
else {
assertTrue (numberInList < 2)
}
}
}
class Number {
}
class Controller {
