// Benchmarks, when ran as tests, would cause strange indentations
|
|
// to appear in the output. This was because padding formatting was
|
|
// applied before the conversion from bench to test, and not afterwards.
|
|
// Now that this bug has been fixed in #118548, this test checks that it
|
|
// does not make a resurgence by comparing the output of --bench with an
|
|
// example stdout file.
|
|
// See https://github.com/rust-lang/rust/issues/104092
