Classification trees are a combinatorial testing technique that allows the tester to represent the data items and their values in a graphical form, and to exclude certain combinations by using constraints or rules. Classification trees can help the tester to visualize and organize the test data, and to generate test cases that cover all relevant combinations of values. The other techniques do not provide a convenient way to exclude certain combinations, or require more complex mathematical calculations. References =

Interoperability is the degree to which two or more systems or components can exchange and use information. It is a crucial quality characteristic for an e-commerce product that needs to interface with backend applications, such as finance, stock control and order delivery. The test plan must include tests to verify that the COTS package can communicate and integrate with the existing systems and applications, and that the data and functionality are consistent and accurate across the interfaces. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 10, section 1.2.2.2.

This is an effective method to employ business users in your testing effort because it allows them to leverage their domain knowledge and experience without requiring them to have technical skills or testing tools.

Test charters are flexible and can be adapted to different test levels and types. They are also suitable for the V-model development lifecycle, which emphasizes verification and validation at each stage of the development process1
