Complement is a black box integration testing framework for Matrix homeservers.
See also Complement Crypto for E2EE specific testing.
You need to have Go and Docker installed. Complement uses Docker API version 1.45, so your docker version must support that. Then:
$ COMPLEMENT_BASE_IMAGE=some-matrix/homeserver-impl go test -v ./tests/...
For a full list of configuration options, see the automatically generated documentation. In addition to the environment variables, all normal Go test config options will work, so to just run 1 named test and include a timeout for the test run:
$ COMPLEMENT_BASE_IMAGE=complement-dendrite:latest go test -timeout 30s -run '^(TestOutboundFederationSend)$' -v ./tests/...
If you need to pass environment variables to the image under test, you can:
- define a pass-through prefix with e.g.
COMPLEMENT_SHARE_ENV_PREFIX=PASS_; then - prefix the desired environment variables with that prefix; e.g.
PASS_SYNAPSE_COMPLEMENT_USE_WORKERS=true.
The homeserver in the test image needs to be able to make requests to the mock homeserver hosted by Complement itself, which may be blocked by firewall software. This will manifest with a subset of the tests (mostly those to do with federation) inexplicably failing.
To solve this, you will need to configure your firewall to allow such requests.
If you are using ufw, this can be done with:
sudo ufw allow in on br-+It is possible to run the test suite using Podman and the compatibility layer for Docker API. Rootless mode is also supported.
To do so you should:
systemctl --user start podman.serviceto start the rootless API daemon (can also be enabled).DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock BUILDAH_FORMAT=docker COMPLEMENT_HOSTNAME_RUNNING_COMPLEMENT=host.containers.internal ...
If all the networking tests don't seem to pass, it might be because the default rootless network command pasta doesn't work in recent versions of Podman (see this issue). If that happens to you, consider changing it in Podman's configuration file located at /etc/containers/containers.conf:
default_rootless_network_cmd = "slirp4netns"
Docker image format is needed because OCI format doesn't support the HEALTHCHECK directive unfortunately.
For instance, for Dendrite:
# build a docker image for Dendrite...
$ git clone https://github.com/element-hq/dendrite
$ (cd dendrite && docker build -t complement-dendrite -f build/scripts/Complement.Dockerfile .)
# ...and test it
$ COMPLEMENT_BASE_IMAGE=complement-dendrite:latest go test -v ./tests/...
If you're looking to run Complement against a local dev instance of Synapse, see element-hq/synapse -> scripts-dev/complement.sh.
If you want to develop Complement tests while working on a local dev instance
of Synapse, use the
scripts-dev/complement.sh
script and set the COMPLEMENT_DIR environment variable to the filepath of
your local Complement checkout. Arguments to go test can be supplied as an argument to the script, e.g.:
COMPLEMENT_DIR=/path/to/complement scripts-dev/complement.sh -run "TestOutboundFederation(Profile|Send)"To run Complement against a specific release of Synapse, build the
"complement-synapse" image with a SYNAPSE_VERSION build argument. For
example:
(cd synapse && docker build -t complement-synapse:v1.36.0 -f docker/complement/Dockerfile --build-arg=SYNAPSE_VERSION=v1.36.0 docker/complement)
COMPLEMENT_BASE_IMAGE=complement-synapse:v1.36.0 go test ./tests/...If you're looking to run against a custom Dockerfile, it must meet the following requirements:
- The Dockerfile must
EXPOSE 8008andEXPOSE 8448for client and federation traffic respectively. - The homeserver should run and listen on these ports.
- The homeserver should become healthy within
COMPLEMENT_SPAWN_HS_TIMEOUT_SECSif aHEALTHCHECKis specified in the Dockerfile. - The homeserver needs to
200 OKrequests toGET /_matrix/client/versions. - The homeserver needs to manage its own storage within the image.
- The homeserver needs to accept the server name given by the environment variable
SERVER_NAMEat runtime. - The homeserver needs to assume dockerfile
CMDorENTRYPOINTinstructions will be run multiple times. - The homeserver needs to use
complementas the registration shared secret for/_synapse/admin/v1/register, if supported. If this endpoint 404s then these tests are skipped.
If you want to write Complement tests and hack on a homeserver implementation at the same time it can be very awkward
to have to docker build the image all the time. To resolve this, Complement support "host mounts" which mount a directory
from the host to the container. This is set via COMPLEMENT_HOST_MOUNTS, on the form HOST:CONTAINER[:ro][;...] where
:ro makes the mount read-only.
For example, for Dendrite on Linux with the default location of $GOPATH, do a one-time setup:
$ git clone https://github.com/element-hq/dendrite ../dendrite
$ (cd ../dendrite && docker build -t complement-dendrite-local -f build/scripts/ComplementLocal.Dockerfile .)
$ mkdir -p ../complement-go-build-cache
$ export COMPLEMENT_BASE_IMAGE=complement-dendrite-local
$ export COMPLEMENT_HOST_MOUNTS="$PWD/../dendrite:/dendrite:ro;$HOME/go:/go:ro;$PWD/../complement-go-build-cache:/root/.cache/go-build"Then simply use go test to compile and test your locally checked out Dendrite:
$ go test -v ./tests/...The default output isn't particularly nice to read. You can use gotestfmt
to make this very pretty. To do so, ask for JSON output via go test -json then pipe the output to gotestfmt.
If you are doing this in CI, make sure to set -o pipefail or else test failures will NOT result in a non-zero exit code
as gotestfmt's exit code (0 as it successfully printed) will replace the previous commands exit code.
See Complement's Github Actions file
for an example of how to do this correctly.
To get started developing Complement tests, see the onboarding documentation.
Complement uses build tags to include or exclude tests for each homeserver. Build tags are comments at the top of the file that look like:
// +build msc2403We have tags for MSCs (the above is in msc2403_test.go) as well as general blacklists for a homeserver implementation e.g Dendrite,
which has the name dendrite_blacklist. These are implemented as inverted tags such that specifying the tag results in the file not
being picked up by go test. For example, apidoc_presence_test.go has:
// +build !dendrite_blacklistand all Dendrite tests run with -tags="dendrite_blacklist" to cause this file to be skipped. You can run tests with build tags like this:
COMPLEMENT_BASE_IMAGE=complement-synapse:latest go test -v -tags="synapse_blacklist,msc2403" ./tests/...
This runs Complement with a Synapse HS and ignores tests which Synapse doesn't implement, and includes tests for MSC2403.
Because MC = 1 - M
As the Matrix federation protocol expects federation endpoints to be served with valid TLS certs, Complement will create a self-signed CA cert to use for creating valid TLS certs in homeserver containers, and mount these files onto your homeserver container:
/complement/ca/ca.crt: the public certificate for the CA. The homeserver under test should be configured to trust certificates signed by this CA (e.g. by adding it to the trusted cert store in/etc/ca-certificates)./complement/ca/ca.key: the CA's private key. This is needed to sign the homeserver's certificate.
For example, to sign your certificate for the homeserver, run at each container start (Ubuntu):
openssl genrsa -out $SERVER_NAME.key 2048
openssl req -new -sha256 -key $SERVER_NAME.key -subj "/C=US/ST=CA/O=MyOrg, Inc./CN=$SERVER_NAME" -out $SERVER_NAME.csr
openssl x509 -req -in $SERVER_NAME.csr -CA /complement/ca/ca.crt -CAkey /complement/ca/ca.key -CAcreateserial -out $SERVER_NAME.crt -days 1 -sha256
To add the CA cert to your trust store (Ubuntu):
cp /complement/ca/ca.crt /usr/local/share/ca-certificates/complement.crt
update-ca-certificates
