// Notes:
|
||
|
|
// 1. Compare this program and its coverage results to those of the similar tests
|
||
|
|
// `panic_unwind.rs` and `try_error_result.rs`.
|
||
|
|
// 2. This test confirms the coverage generated when a program includes `TerminatorKind::Abort`.
|
||
|
|
// 3. The test does not invoke the abort. By executing to a successful completion, the coverage
|
||
|
|
// results show where the program did and did not execute.
|
||
|
|
// 4. If the program actually aborted, the coverage counters would not be saved (which "works as
|
||
|
|
// intended"). Coverage results would show no executed coverage regions.
|
||
|
|
// 6. If `should_abort` is `true` and the program aborts, the program exits with a `132` status
|
||
|
|
// (on Linux at least).
