SyTest

Dendrite uses SyTest for its integration testing. When creating a new PR, add the test IDs (see below) that your PR should allow to pass to sytest-whitelist in dendrite's root directory. Not all PRs need to make new tests pass. If we find your PR should be making a test pass we may ask you to add to that file, as generally Dendrite's progress can be tracked through the amount of SyTest tests it passes.

Finding out which tests to add

We recommend you run the tests locally by manually setting up SyTest or using a SyTest docker image. After running the tests, a script will print the tests you need to add to sytest-whitelist.

You should proceed after you see no build problems for dendrite after running:

./build.sh

Manually Setting up SyTest

Make sure you have Perl v5+ installed, and get SyTest with:

(Note that this guide assumes your SyTest checkout is next to your dendrite checkout.)

git clone -b develop https://github.com/matrix-org/sytest
cd sytest
./install-deps.pl

Set up the database:

sudo -u postgres psql -c "CREATE USER dendrite PASSWORD 'itsasecret'"
sudo -u postgres psql -c "CREATE DATABASE sytest_template OWNER dendrite"
mkdir -p "server-0"
cat > "server-0/database.yaml" << EOF
args:
    user: dendrite
    database: dendrite
    host: 127.0.0.1
    sslmode: disable
type: pg
EOF

Run the tests:

./run-tests.pl -I Dendrite::Monolith -d ../dendrite/bin -W ../dendrite/sytest-whitelist -O tap --all | tee results.tap

where tee lets you see the results while they're being piped to the file.

Once the tests are complete, run the helper script to see if you need to add any newly passing test names to sytest-whitelist in the project's root directory:

../dendrite/show-expected-fail-tests.sh results.tap ../dendrite/sytest-whitelist ../dendrite/sytest-blacklist

If the script prints nothing/exits with 0, then you're good to go.

Using a SyTest Docker image

Ensure you have the latest image for SyTest, then run the tests:

docker pull matrixdotorg/sytest-dendrite
docker run --rm -v /path/to/dendrite/:/src/ matrixdotorg/sytest-dendrite

where /path/to/dendrite/ should be replaced with the actual path to your dendrite source code. The output should tell you if you need to add any tests to sytest-whitelist.
