Dead Code – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
Code that cannot be reached and therefore is impossible to execute.
In simple words
Code that no execution path can ever reach — usually left over from refactoring or bad conditionals.
Exam tip
Static analyzers detect dead code; removing it lowers maintenance cost.
