An assertion is a piece of code that’s used during development when the compilation debug mode is activated. It
allows a program to check itself as it runs. When an assertion is true, that means everything is operating as expected.
In non-debug mode, all Debug.Assert calls
are automatically left out (via the Conditional("DEBUG") mechanism). So, by
contract, the boolean expressions that are evaluated by those assertions must not contain any side effects. Otherwise, when leaving the debug mode, the functional behavior
of the application is not the same anymore.
The rule will raise if the method name starts with any of the following remove, delete, add,
pop, update, retain, insert, push, append, clear,
dequeue, enqueue, dispose, put, or set, although SetEquals will be
ignored.
