A Testing Strategy for Abstract Classes [Draft]
One of the characteristics of the increasingly widespread use of object-oriented libraries and the resulting intensive use of inheritance is the proliferation of dependencies on abstract classes. Since abstract classes cannot be instantiated, they cannot be tested in isolation using standard execution-based testing strategies. A standard approach to testing abstract classes is to instantiate a ...
متن کاملUsing Contracts and Boolean Queries to Improve the Quality of Automatic Test Generation
Since test cases cannot be exhaustive, any effective test case generation strategy must identify the execution states most likely to uncover bugs. The key issue is to define criteria for selecting such interesting states. If the units being tested are classes in object-oriented programming, it seems attractive to rely on the boolean queries present in each class, which indeed define criteria on...

متن کاملSpecification-Driven Unit Test Generation for Java Generic Classes
Several approaches exist to automatically derive test cases that check the conformance of the implementation of abstract data types (ADTs) with respect to their specification. However, they lack support for the testing of implementations of ADTs defined by generic classes. In this paper, we present a novel technique to automatically derive, from specifications, unit test cases for Java generic ...
