Study Notes

Syntax-Based Testing Approaches

Two approaches for developing tests based on syntax: exhaustive testing and fuzz testing

Fuzzing or Fuzz Testing

Objective of fuzzing: to test the robustness of a system by providing invalid or unexpected input to observe its behavior

Syntax Manipulation

Syntax manipulation: a common use is to generate test cases that are syntactically valid but semantically invalid

Violating Syntax

Purpose of violating syntax: to test the error handling capabilities of a system
Example: providing a malformed XML file to a parser to test how it handles errors
