Form and business logic validation – manual and exploratory tests

Forms are a key point of contact between the user and the application. Errors in validation or business logic can lead to incorrect data, user frustration, and even legal risk.

Black-box techniques

• partitioning into equivalence classes (equivalence classes - sets of input and output data for which we assume the system will behave in the same way).
• boundary value analysis,
• decision table-based testing,
• state transition testing.

Manual testing

• systematic checking of fields and rules according to a checklist,
• we check, among other things, the correctness of fields, error messages, and the correctness of the flow.

Exploratory testing

• a less formal approach – the tester takes on the role of the user,
• looking for unusual scenarios, e.g. very long field values, unusual data formats (e.g. dates), omission of required fields
• goal: to discover errors that were not anticipated in the analyses.
