Add unit testing harness - #3828
Conversation
Introduces src/test/, a QtTest-based unit test target (jamulus-test)
covering CProtocol's on-wire framing contract:
- golden-frame tests pin the exact bytes production emits today for a
fixed-length and a variable-length message body, so any accidental
wire format change fails loudly instead of silently -- the expected
hex string is built field by field (TAG, message ID, sequence
counter, data length, data, CRC), each `+=` line commented with what
that field is, against a fresh CProtocolTester's SentFrames()
- a frame acceptance/rejection contract test trio (AcceptValidFrame,
RejectInvalidFrame with bad CRC/length/truncation/junk rows, and
IgnoreAcknWithEmptyBody -- the regression test for
jamulussoftware#302, fixed in
024ebb4: an ACKN message with a valid checksum but no data caused
an out-of-bounds read; the crafted frame is still well-formed so
it's accepted at the frame level, but must be silently dropped with
no signal fired, and the ASan/UBSan matrix job is what gives the
"no OOB" part of that its teeth) checks how many frames the
receiving side actually parsed and accepted, building each frame
imperatively from a real sent frame (LastSentFrame()) plus a small
set of named mutation helpers
- one round-trip test through a connected sender/receiver pair
(CProtocolTester) sends a message on one side and asserts, against
an event log of everything the other side received, that exactly
the expected signal fired with the expected arguments
CProtocolTester (src/test/protocoltester.h) is the one public type this
header exposes: a struct-like pair of CProtocol instances (Sender,
Receiver) wired together in both directions -- the same wiring CChannel
uses for two peers, including routing acknowledgements back so the
sender's queue advances -- plus:
- a sent frame log: every frame Sender hands to MessReadyForSending is
recorded as both a hex string (SentFrames(), for golden frame
comparisons) and raw bytes (LastSentFrame(), for tests that mutate a
real frame); a fresh instance's first send has sequence counter 0,
which is what makes golden frames byte-for-byte reproducible
- a receiver-side acceptance count: ReceivedAndAcceptedMessageCount()
counts frames that passed frame parsing on the receiver side and
were handed to ParseMessageBody(); a failed parse -- whether from a
real send or a malformed frame injected via SendRawBytes() -- is a
silently dropped, countable non-event rather than an assertion
failure, and is tracked per direction so an ACK flowing back to the
sender never affects the receiver's own count
- a received signal log: every non-CLM "receiving" signal CProtocol
emits from ParseMessageBody (protocol.h's
ChangeJittBufSize..RecorderStateReceived block, 21 signals) is wired
to append one formatted "SignalName(arg1, arg2)" line to
ReceivedLog(), so a test can QCOMPARE the whole log against what it
expects -- which also proves, for free, that no other wired signal
fired
- ToByteArray()/FromByteArray(), the frame mutators
TruncateBy()/CorruptCRC()/SetDeclaredLength(), and ReplaceIdAndBody()
(rebuilds a frame with a different ID/body, recomputing length and
CRC) for crafting ID/body combinations a real Create*Mes() call
can't produce
Tests hold their own frames/expectations and call these helpers
directly, with no builder chain, lambda-taking capture function, or
shared error-message plumbing in the public surface to look through.

.github/scripts/run-unit-tests.py is a single Python (stdlib only) driver for building and running the unit test suite across all three CI platforms (Linux, macOS, Windows) with one "build" and one "run" subcommand. On Windows it also bootstraps the MSVC environment itself, using the same env-diffing technique windows/deploy_windows.ps1's Initialize-Build-Environment already uses (call vcvarsall.bat, diff the environment before/after) -- it has to happen again here rather than once in the workflow, since build and run are two separate GitHub Actions steps and an environment set up in one does not survive into the next. "run" is also the test-count gate: after running the binary it parses test-results.xml (stdlib only) and exits nonzero unless the suite reports at least one test and zero failures/errors -- the binary's own exit code is ignored throughout, since it's unreliable on Windows runners, so test-results.xml is the sole source of truth. .github/scripts/summarize-test-results.py parses that same JUnit XML and appends a pass/fail table (plus any failing test names/messages) to the job summary. It is reporting only and always exits 0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HGdLtGxMrbExBFG3aReNAH
.github/workflows/unit-tests.yml runs the new suite on every push and
pull request touching src/**, this workflow file, or the scripts it
calls (plus workflow_dispatch for manual runs), mirroring the trigger
shape of the repository's other main-branch check workflows.
A 6-job matrix covers:
- Linux (Qt 5.15, ubuntu-22.04) -- proves the suite's Qt >= 5.12 floor
- Linux (Qt 6, ubuntu-24.04)
- macOS (Qt 6) and Windows (Qt 6, MSVC) -- Qt is set up by reusing
autobuild.yml's own setup scripts (.github/autobuild/mac.sh,
windows.ps1) and its exact cache key/paths, so this job shares that
cache instead of keeping a separate one; heavier than this suite
strictly needs (extra Qt modules, a 32-bit Qt, jom on Windows) in
exchange for that shared cache
- Linux (Qt 6, ASan/UBSan) -- same toolchain with sanitizers enabled
via qmake command line flags, to catch memory/UB issues a plain
build wouldn't
- Linux (Qt 6, coverage) -- same toolchain instrumented with gcov,
producing an HTML report artifact plus a Markdown summary table for
src/ (excluding the test suite itself)
Every job builds and runs the suite via run-unit-tests.py, which is
also the gate; Summarize test results (always run) and the coverage
steps (always run, coverage jobs only) still render their output even
if that gate failed. The workflow only needs `permissions: contents:
read` throughout.

Pull request overview
Adds an initial QtTest-based unit test harness for Jamulus’ protocol layer, plus CI automation to build/run the suite across multiple platforms/configurations (including sanitizers and coverage), without changing production runtime code.
Changes:
- Introduces a protocol test suite with golden on-wire frame checks, malformed-frame rejection cases, round-trip signal logging, and a regression test for the ACKN empty-body OOB issue (#302).
- Adds a dedicated qmake project (
src/test/test.pro) and helper harness (CProtocolTester) for wiring twoCProtocolinstances and logging frames/signals. - Adds a GitHub Actions workflow to build/run tests on Linux/macOS/Windows and publish JUnit + optional coverage artifacts, with summary reporting.

Both from PR review on jamulussoftware#3828: - src/test/protocoltester.h: CProtocolTester::TruncateBy() now clamps the resize at 0, so truncating by more than the frame's size yields an empty frame instead of a negative resize (which wraps to a huge size_t and would abort/corrupt memory). - .github/scripts/run-unit-tests.py: msvc_environment()'s snapshot() helper now checks the subprocess return code and fails fast with the command plus its captured stdout/stderr if it's nonzero, instead of letting a broken vcvarsall.bat call surface later as a confusing compiler-not-found error.

The key hardcoded the version string alongside the env.QT_VERSION definition above, so the two could drift after a Qt update. The interpolated key is byte-identical today, keeping the cache shared with autobuild.yml's macOS job. Per PR review.

@ann0see Thanks for catching this.
Dropping QT_NO_DEPRECATED_WARNINGS surfaced a deprecation warning the build output on util.cpp:1556 (QLibraryInfo::location() → path(), deprecated in Qt 6). My agent hid it as CI noise but I agree that the the test workflow should surface it rather than hide it. Addressed in ccbb7f5.

Curious of other test cases then too obviously. But not part of this PR.
autobuild.yml's macOS main build entry becomes the single source of truth; a step extracts QT_VERSION from it (failing loudly if the parse does not yield exactly one plausible version) instead of pinning a copy here that could drift.

What is your take on moving those files to /test/
There was a problem hiding this comment.
Normally when I work on JS projects I put the test files next to the source files (so the tests are "co-located" with the source files).
For example, if the implementation file is at src/packlets/foo/util.js, then the test would be in either of these:
src/packlets/foo/util.test.jssrc/packlets/foo/__tests__/util-test.js
But when it comes to Qt projects, I have no takes. My guess is that it's only there so that the build system doesn't have to be changed to become aware of a new top-level folder. Let me ask my agent about this and I will get back.

I checked with the agent. I have no strong preference. We can move to /test/ if you prefer but we'll also have to:
- Update
update-copyright-notices.shto also scan thetestdirectory. - Update
Jamulus.proso thatmake clang_formatalso work on thetestdirectory.
What's your preference?

Intuitively I'd expect tests to be in /test/

test/protocoltester.h:135
- SetDeclaredLength() writes to vecbyFrame[5] and [6] unconditionally. If a future test calls it after truncating a frame below the header size, this will read/write out of bounds and crash the test binary. Guard against short frames before mutating the length field.
// overwrites vecbyFrame's declared body length field, independently of the
// body bytes actually present
static void SetDeclaredLength ( CVector<uint8_t>& vecbyFrame, const int iLen )
{
vecbyFrame[5] = static_cast<uint8_t> ( iLen & 0xFF );
vecbyFrame[6] = static_cast<uint8_t> ( ( iLen >> 8 ) & 0xFF );
}
TruncateBy documents that an oversize truncation yields an empty frame, so a test can legally chain it into CorruptCRC, which indexed the last byte unconditionally. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HGdLtGxMrbExBFG3aReNAH

Anchor and unify the build-version grammar.
.github/autobuild/mac.sh:67 is unanchored, and .github/autobuild/windows.ps1:91 permits arbitrary suffixes. Both accept 1.2.3/other. The artifact functions then interpolate that value into deploy/..., which can create an invalid nested destination and make artifact transfer fail.
Use the same anchored expression in both validators. Allow N.N.N or the N.N.Ndev-<git-describe output> value produced by .github/autobuild/get_build_vars.py. Reject path separators and all other suffixes.

Fail when the QtTest process exits nonzero. cmd_run() discards subprocess.run(...)'s return code and checks only the XML report. A sanitizer or teardown failure after QtTest finalizes the report can leave zero failures in XML while the process exits nonzero. Require returncode == 0 and a passing XML report.

Validate the upstream version before Perl interpolation.
A malicious gcovr/gcovr release tag can inject Perl through the replacement string. The workflow executes this code with deploy-key-backed Git access. Restrict the value to the numeric dotted version format used by GCOVR_VERSION.
Proposed fix

+ get_upstream_version: GH_REPO=gcovr/gcovr gh release view --json tagName --jq .tagName | sed -re 's/^v//' | grep -Ex '[0-9]+(\.[0-9]+)*'📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Short description of changes
Added a unit test harness (based on QtTest) with a first test suite for the protocol layer, along with a CI workflow covering:
No production code is changed.
The suite (19 cases) covers:
CProtocolemits on the wire.CProtocolinstances, observed via an event log of received signals.CHANGELOG: SKIP
Context: Fixes an issue?
First step toward #2428 (automated testing in CI). This PR only covers unit-testing. A real client/server smoke test is planned separately.
Does this change need documentation? What needs to be documented and how?
No.
Status of this Pull Request
Working implementation, CI-verified.
What is missing until this pull request can be merged?
Nothing known.
Notes for reviewers:
Running locally:
Alternatively:
The test binary's exit code is ignored because on Windows runners the binary's stdout/exit behavior is unreliable. We have a Python script inspect the generated JUnit XML instead (details in
run-unit-tests.py).We built a bespoke test results reporting script in Python. We considered richer PR annotations via a report action (e.g. dorny/test-reporter), but they require enabling extra permissions that PRs from forks do not have (like
checks: write).The workflow is admittedly long (~220 lines); most of it is the per-platform Qt/MSVC setup. We did not refactor them into reusable actions to keep this PR self-contained.
I built this with help from my coding agent (Claude Code with Fable 5). You can read the full conversation here (but it's quite long!). It took a lot of steering to arrive at the current shape.
