tests/unit: add websock handshake test

2026-09-07T10:31:03+00:00

Check that malformed HTTP greetings are answered with an HTTP 400 rather than an empty response. The no-space case is the one which used to leave the response buffer empty.

tests: tag slow tests with 'slow' suite for easy filtering

2026-08-25T11:20:43+00:00

Add several RCU and thread-pool unit tests to the slow_tests dict, and tag all slow tests (both qtest and unit) with a 'slow' suite so they can be excluded or selected via meson test --suite/--no-suite.

tests/unit: add reproducer for BlockAcctStats histogram locking race

2026-08-03T08:42:29+00:00

block_latency_histogram_set() and block_latency_histograms_clear() replace BlockLatencyHistogram's nbins/boundaries/bins without taking stats->lock, while block_account_one_io() reads those same fields under that lock from whatever iothread completes the I/O. Add a test that races two real threads against block_latency_histogram_set() and block_acct_start()/block_acct_done() on the same BlockAcctStats. Applied here it passes, since the previous two commits already take the lock; reverting them locally reproduces the abort this series fixes, in about a second. Signed-off-by: Denis V.

tests: add unit tests for RamDiscardManager multi-source aggregation

2026-06-22T21:08:49+00:00

Add various unit tests for the RamDiscardManager multi-source aggregation functionality. The test uses a TestRamDiscardSource QOM object that tracks populated state via a bitmap, similar to RamBlockAttributes implementation.

tests/unit: add test-envlist covering setenv/unsetenv name matching

2026-06-03T16:45:06+00:00

util/envlist had no test coverage. Add tests/unit/test-envlist exercising the public envlist API and pinning down the prefix-match hazard fixed in the previous commit: - envlist_unsetenv("FOO") must not remove an entry named "FOOBAR"; - envlist_setenv("FOO=...") must not replace an existing "FOOBAR=..." entry placed earlier in the list (envlist_setenv() inserts at the head, so the first prefix match wins under the old strncmp rule). Also cover the rest of the contract: head-insertion order observed through envlist_to_environ(), replacement of an existing variable, the count argument of envlist_to_environ(), and the documented EINVAL paths (NULL inputs, setenv without '=', unsetenv with '=').

tests/qtest: Individual verbose switches

2026-05-12T12:40:08+00:00

Allow logging to be set for specific parts of QTest. Having a single QTEST_LOG knob creates an output stream that is almost useless due to spamming from some operations. Add a backward-compatible way of selecting which parts will be made verbose. Reuse the existing QTEST_LOG variable. The new options are: QTEST_LOG= fuzz - fuzz.c qga - unit/test-qga.c qmp - libqmp.c qtest - QTest device, i.e. -qtest-log option test - generic term for usage of all tests E.g.: QTEST_LOG=fuzz,qga,qmp,qtest,test equivalent to QTEST_LOG=1 QTEST_LOG=qmp,qtest enables logging of qmp operations from libqmp.c and logging of the qtest device. QTEST_LOG=test,qmp enable test output and libqmp.c output. QTEST_LOG=-qmp enable all output, except for libqmp.c Acked-by: Peter Xu Link: https://lore.kernel.org/qemu-devel/20260429003130.15164-3-farosas@suse.de Signed-off-by: Fabiano Rosas

tests: add test for json-streamer.c error recovery

2026-04-30T13:50:18+00:00

Before rewriting the error recovery code to work in a push parsing setup, make sure that we have tests for it. Cover various cases of invalid JSON, to check that structural recovery based on balanced brackets and braces works; and lexer-based recovery which documents "\f" as a sure fire way to reset the lexer.

tests/unit: remove block layer code from test-nested-aio-poll

2024-10-02T10:58:46+00:00

GCC is reporting a NULL pointer dereference when compiling aio_wait_kick() with LTO. The issue is that test-nested-aio-poll.c does not call qemu_init_main_loop(). It doesn't _need_ to because it never calls AIO_WAIT_WHILE(), but it seems that LTO does not do enough dead-code elimination to catch that. Fortunately aio_wait_kick() is only used in few places, and only in block layer or system emulation code; and this test only needs the core event loop functionality. It does not even need iothreads. So remove everything that calls aio_wait_kick(), which is nice for coverage compared to adding the call to qemu_init_main_loop(). Reported-by: Richard W.M.
