From e96b4e479a3835d43d3c0bfd1028b5ac9d99cfec Mon Sep 17 00:00:00 2001 From: Zalathar Date: Fri, 6 Sep 2024 15:41:10 +1000 Subject: [PATCH] coverage: Extract `executor::block_on` from several async coverage tests By moving `block_on` to an auxiliary crate, we avoid having to keep a separate copy of it in every async test. (This also incorporates some small tweaks to the headers in `await_ready.rs`.) --- tests/coverage/async.cov-map | 100 ++++++++++---------- tests/coverage/async.coverage | 21 +--- tests/coverage/async.rs | 21 +--- tests/coverage/async2.cov-map | 24 ++--- tests/coverage/async2.coverage | 21 +--- tests/coverage/async2.rs | 21 +--- tests/coverage/async_block.cov-map | 8 +- tests/coverage/async_block.coverage | 21 +--- tests/coverage/async_block.rs | 21 +--- tests/coverage/auxiliary/executor.rs | 19 ++++ tests/coverage/await_ready.cov-map | 16 +--- tests/coverage/await_ready.coverage | 37 +++----- tests/coverage/await_ready.rs | 31 ++---- tests/coverage/closure_macro_async.cov-map | 16 ++-- tests/coverage/closure_macro_async.coverage | 21 +--- tests/coverage/closure_macro_async.rs | 21 +--- 16 files changed, 142 insertions(+), 277 deletions(-) create mode 100644 tests/coverage/auxiliary/executor.rs diff --git a/tests/coverage/async.cov-map b/tests/coverage/async.cov-map index 1ba165f1e49..43b497a1d3f 100644 --- a/tests/coverage/async.cov-map +++ b/tests/coverage/async.cov-map @@ -1,103 +1,103 @@ Function name: async::c -Raw bytes (9): 0x[01, 01, 00, 01, 01, 09, 01, 00, 19] +Raw bytes (9): 0x[01, 01, 00, 01, 01, 0c, 01, 00, 19] Number of files: 1 -
