## 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`.

### Using the SyTest Docker image
Use the following commands to pull the latest SyTest image and run the tests:
```sh
docker pull matrixdotorg/sytest-dendrite
docker run --rm -v /path/to/dendrite/:/src/ -v /path/to/log/output/:/logs/ matrixdotorg/sytest-dendrite
```
`/path/to/dendrite/` should be replaced with the actual path to your dendrite
source code. The test results TAP file and homeserver logging output will go to
`/path/to/log/output`. The output of the command should tell you if you need to
add any tests to `sytest-whitelist`.
When debugging, the following Docker `run` options may also be useful:
* `-v /path/to/sytest/:/sytest/`: Use your local SyTest repository at
`/path/to/sytest` instead of pulling from GitHub. This is useful when you want
to speed things up or make modifications to SyTest.
* `--entrypoint bash`: Prevent the container from automatically starting the
tests. When used, you need to manually run `/bootstrap.sh dendrite` inside
the container to start them.
### Manually Setting up SyTest

If you don't want to use the Docker image, you can also run SyTest by hand. Make

`dendrite` checkout.)

### Using a SyTest Docker image
Ensure you have the latest image for SyTest, then run the tests:
```sh
docker pull matrixdotorg/sytest-dendrite
docker run --rm -v /path/to/dendrite/:/src/ matrixdotorg/sytest-dendrite
