Rekayasa Perangkat Lunak 2009/2010 White Box Testing?  metode uji yang mempertimbangkan mekanisme internal sistem atau komponen dari sistem (IEEE). Test case yang dihasilkan dapat: Menjamin seluruh independent path di dalam modul telah dijalankan sekurang-kurangnya sekali Menjalankan seluruh logical decision baik dari sisi benar maupun salah Menjalankan seluruh loop sesuai dengan batasannya Menjalankan seluruh struktur data internal untuk menjamin validitas data

Prinsip White Box Unit testing  individual software units. Rekayasa Perangkat Lunak 2009/2010 Prinsip White Box Unit testing  individual software units. Integration testing  in which software components, hardware components, or both are combined and tested to evaluate the interaction between them Regretion testing  verify that modifications have not caused unintended effects and that the system or component still complies with its specified requirements

Control Structure Testing Rekayasa Perangkat Lunak 2009/2010 Metode White Box Basis Path Testing Control Structure Testing

Rekayasa Perangkat Lunak 2009/2010 Basis Path Testing If a player lands on a property owned by other players, he or she needs to pay the rent. If the player does not have enough money, he or she is out of the game. If the property is not owned by any players, and the player has enough money buying the property, he or she may buy the property with the price associated with the property.
