In `@test/integ/eventReEnqueue/eventReEnqueue.cpp`:
- Around line 33-37: The current early-return in the device availability check
(if(!devSelector.isAvailable()) { ... return; }) causes tests to be marked as
passed; replace the plain return with Catch2's skip macro (e.g., SKIP("No device
available for " + deviceSpec.getName()) or CATCH_SKIP(...) depending on project
configuration) so the branch in devSelector.isAvailable() records an explicit
skipped test using the message that includes deviceSpec.getName().
- Around line 40-41: The test currently creates producerQueue and consumerQueue
with device.makeQueue(queueKind::blocking), which serializes enqueues and hides
event re-enqueue bugs; update both calls to use queueKind::nonBlocking so
producerQueue and consumerQueue are non-blocking and the asynchronous race
around consumerQueue.waitFor(readyEvent) can surface stale-event failures
(change device.makeQueue(queueKind::blocking) to
device.makeQueue(queueKind::nonBlocking) for the producerQueue and consumerQueue
declarations).

Catch2 SKIP macro syntax version 3
💡 Result:
In Catch2 v3, the runtime-skip macro is:
- Syntax:
SKIP( [streamable expression] )(the message is optional, soSKIP()is valid) [1] - Example:
[1]
TEST_CASE("copy files between drives") { if (getNumberOfHardDrives() < 2) { SKIP("at least two hard drives required"); } // ... }
Notes:
SKIPwas introduced in Catch2 3.3.0. [1]- Like an explicit
FAIL,SKIPstops execution of the current test/section at that point. [1]

🌐 Web query:
Catch2 CATCH_SKIP vs SKIP macro
💡 Result:
In Catch2, SKIP(...) and CATCH_SKIP(...) are the same feature, just exposed under different naming depending on configuration:
SKIP(...)is the default user-facing macro (when you are not prefixing all macros). It records an explicit skip and then immediately aborts the current test case/section (similar control-flow toFAIL). [1][2]CATCH_SKIP(...)is the prefixed equivalent that is only provided when you compile withCATCH_CONFIG_PREFIX_ALL(to avoid macro name collisions by prefixing everything withCATCH_). Its implementation is the same (explicit skip + abort). [1]
Notes:
- Runtime skipping via
SKIP/CATCH_SKIPwas introduced in Catch2 v3.3.0. [2]
Sources:
[1] Catch2 header (catch_test_macros.hpp) showing CATCH_SKIP vs SKIP definitions (prefixed vs unprefixed). (raw.githubusercontent.com)
[2] Catch2 docs: “Explicitly skipping… at runtime” (SKIP macro, behavior, version introduced). (catch2-temp.readthedocs.io)

Mark unavailable-device cases as skipped instead of passed.
On Line 36, return; marks "no device" as a passing test. Use Catch2's SKIP() macro (available in v3.3.0+) to report this case explicitly.
Proposed change
if(!devSelector.isAvailable())
{
- std::cout << "No device available for " << deviceSpec.getName() << std::endl;
- return;
+ SKIP(std::string("No device available for ") + deviceSpec.getName());
}Note: Ensure the correct macro name (SKIP or CATCH_SKIP if prefixed) matches your project's Catch2 configuration. The SKIP() macro stops test execution and records an explicit skip in CI reports.

Use non-blocking queues to properly test event re-enqueue semantics.
Blocking queues serialize all enqueue operations, completing them before consumerQueue.waitFor(readyEvent) executes. This masks failures in event re-enqueue—if the event doesn't move to the later kernel completion point, the test still passes because all work is already done. Non-blocking queues create an actual asynchronous race where a stale event would cause the consumer to observe pre-kernel data.
Change lines 40–41 to use queueKind::nonBlocking:
Proposed change
- onHost::Queue producerQueue = device.makeQueue(queueKind::blocking);
- onHost::Queue consumerQueue = device.makeQueue(queueKind::blocking);
+ onHost::Queue producerQueue = device.makeQueue(queueKind::nonBlocking);
+ onHost::Queue consumerQueue = device.makeQueue(queueKind::nonBlocking);📝 Committable suggestion
