A test is considered failed when a sample trace exceeds the threshold. Failed tests return the same exit code as passed tests, requiring test frameworks to determine the result by searching for "hit stop tracing" in the output. Assign a distinct exit code for failed tests to enable the use of shell expressions and seamless integration with testing frameworks without the need to parse output. Add enum type for return value.
