Supervision strategies
Learn Supervision strategies in Erlang through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.
Supervision strategies is a focused Erlang lesson inside OTP Behaviours. The example uses the construct named in the lesson directly rather than reusing a generic placeholder.
Trace the example from its inputs through Supervision strategies and identify the behavior that would change if that construct were removed or replaced. Pay attention to the language-specific rules shown by the syntax, because neighboring lessons intentionally exercise different mechanisms.
Topic-specific example
-module(example).
-export([run/0]).
run() -> lists:sum([47,48,49]). % Supervision strategies
For Supervision strategies, test one realistic boundary: empty data, invalid input, unavailable resources, lifetime/cleanup, type constraints, or concurrency timing where applicable. A successful happy path is not enough to prove the construct is used correctly.
