[PATCH v3 0/2] MR8862: mmdevapi/tests: Rewrite capturing tests.
I began working on this to address some flakyness (see e.g. https://gitlab.winehq.org/wine/wine/-/jobs/183916), and eventually I ended up rewriting `test_capture()` because the previous implementation looked somewhat incomplete. -- v3: mmdevapi/tests: Reduce the period of a rendering test. https://gitlab.winehq.org/wine/wine/-/merge_requests/8862
From: Giovanni Mascellani <gmascellani(a)codeweavers.com> The old tests only requested a few packets and only simulated some of the possible logic paths. They were also somewhat flaky. The new tests are an attempt at improving completeness and reliability. --- dlls/mmdevapi/tests/capture.c | 422 +++++++++++++++------------------- 1 file changed, 184 insertions(+), 238 deletions(-) diff --git a/dlls/mmdevapi/tests/capture.c b/dlls/mmdevapi/tests/capture.c index e4f8eea5556..23cba93a402 100644 --- a/dlls/mmdevapi/tests/capture.c +++ b/dlls/mmdevapi/tests/capture.c @@ -21,6 +21,7 @@ * - IAudioClient with eCapture and IAudioCaptureClient */ +#include <stdint.h> #include <math.h> #include "wine/test.h" @@ -106,313 +107,258 @@ static void test_uninitialized(IAudioClient *ac) CloseHandle(handle); } -static void test_capture(IAudioClient *ac, HANDLE handle, WAVEFORMATEX *wfx) +struct read_packets_data { - IAudioCaptureClient *acc; - HRESULT hr; - UINT32 frames, next, pad, sum = 0; - BYTE *data; - DWORD flags; - UINT64 pos, qpc; - REFERENCE_TIME period; - - hr = IAudioClient_GetService(ac, &IID_IAudioCaptureClient, (void**)&acc); - ok(hr == S_OK, "IAudioClient_GetService(IID_IAudioCaptureClient) returns %08lx\n", hr); - if (hr != S_OK) - return; - - ok(ResetEvent(handle), "ResetEvent\n"); - - hr = IAudioCaptureClient_GetNextPacketSize(acc, &next); - ok(hr == S_OK, "IAudioCaptureClient_GetNextPacketSize returns %08lx\n", hr); + UINT64 expected_dev_pos; + BOOL discontinuity_at_0; + BOOL discontinuity_at_later; +}; - hr = IAudioClient_GetCurrentPadding(ac, &pad); - ok(hr == S_OK, "GetCurrentPadding call returns %08lx\n", hr); - ok(next == pad, "GetNextPacketSize %u vs. GCP %u\n", next, pad); - /* later GCP will grow, while GNPS is 0 or period size */ +static void read_packets(IAudioClient *ac, IAudioCaptureClient *acc, HANDLE handle, + unsigned int packet_count, struct read_packets_data *data) +{ + unsigned int idx = 0; + HRESULT hr; - hr = IAudioCaptureClient_GetNextPacketSize(acc, NULL); - ok(hr == E_POINTER, "IAudioCaptureClient_GetNextPacketSize(NULL) returns %08lx\n", hr); + data->discontinuity_at_0 = FALSE; + data->discontinuity_at_later = FALSE; - data = (void*)0xdeadf00d; - frames = 0xdeadbeef; - flags = 0xabadcafe; - hr = IAudioCaptureClient_GetBuffer(acc, &data, NULL, NULL, NULL, NULL); - ok(hr == E_POINTER, "IAudioCaptureClient_GetBuffer(data, NULL, NULL) returns %08lx\n", hr); + while (idx < packet_count) + { + UINT64 dev_pos, qpc_pos, dev_pos2, qpc_pos2; + UINT32 next_packet_size, padding, frames, frames2; + DWORD flags, flags2; + BYTE *ptr; - hr = IAudioCaptureClient_GetBuffer(acc, NULL, &frames, NULL, NULL, NULL); - ok(hr == E_POINTER, "IAudioCaptureClient_GetBuffer(NULL, &frames, NULL) returns %08lx\n", hr); + winetest_push_context("packet %u", idx); - hr = IAudioCaptureClient_GetBuffer(acc, NULL, NULL, &flags, NULL, NULL); - ok(hr == E_POINTER, "IAudioCaptureClient_GetBuffer(NULL, NULL, &flags) returns %08lx\n", hr); + hr = IAudioCaptureClient_GetNextPacketSize(acc, &next_packet_size); + ok(hr == S_OK, "GetNextPacketSize returns %08lx\n", hr); - hr = IAudioCaptureClient_GetBuffer(acc, &data, &frames, NULL, NULL, NULL); - ok(hr == E_POINTER, "IAudioCaptureClient_GetBuffer(&ata, &frames, NULL) returns %08lx\n", hr); - ok(broken((DWORD_PTR)data == 0xdeadf00d) || /* <= win8 */ - data == NULL, "data is reset to %p\n", data); - ok(frames == 0xdeadbeef, "frames is reset to %08x\n", frames); - ok(flags == 0xabadcafe, "flags is reset to %08lx\n", flags); + if (next_packet_size == 0) + { + /* There is some room for flakyness here, in theory a packet could arrive between the + * GetNextPacketSize() call and the GetBuffer() call.

From: Giovanni Mascellani <gmascellani(a)codeweavers.com> The test that checks that GetBuffer() fails at iterations later than zero is a bit flaky on the CI. I suspect that's because the CI virtual machine is a bit overcommitted and sleeps can be longer than expected. Emptying the buffer more often should help avoiding it grows enough to trigger the failure. --- dlls/mmdevapi/tests/render.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/dlls/mmdevapi/tests/render.c b/dlls/mmdevapi/tests/render.c index 3febeb4c4fb..17dd2efbf9e 100644 --- a/dlls/mmdevapi/tests/render.c +++ b/dlls/mmdevapi/tests/render.c @@ -1422,8 +1422,8 @@ static void test_clock(int share) last = pos; for(i=0; i < 9; i++) { - Sleep(100); - slept += 100; + Sleep(50); + slept += 50; hr = IAudioClock_GetPosition(acl, &pos, &pcpos); ok(hr == S_OK, "GetPosition failed: %08lx\n", hr); -- GitLab https://gitlab.winehq.org/wine/wine/-/merge_requests/8862
