Matrix Synapse Mock API Server

This project and associated docker containers provide a partial mock of the main Matrix Synapse server and can be used for testing of Synapse integrations.

Quick setup using Docker

Run the following command to get your mock server up and running:

docker run -p 8001:80 moodlehq/matrixsynapse_mock

API information

All endpoints must be prefixed with a serverID to allow for parallel runs, for example:

http://localhost:8001/serverID/API

In addition to the standard endpoints, additional endpoints are provided for creating an Admin user: Expected method is (POST)

/backoffice/create-admin

In addition, the following endpoint can be used to trigger a reset between tests: Expected method is (POST)

/backoffice/reset

Back office request example:

curl -i GET http://elementmock:8001/serverID/backoffice/create-admin

Error response example

{
    "errcode" : "M_UNRECOGNIZED",
    "error" : "Unrecognized request"
}

API coverage

The following are the currently mocked API endpoints. These should respond with the same HTTP status code, content type and response content as a real Synapse server.

Synapse

Call API endpoint without Auth Header:
curl -i -X GET http://localhost:8001/someServerID/_synapse/admin/v2/users/@barzuser:synapse

Call API endpoint using wrong HTTP method:

curl -i --header "Authorization: Bearer syt_YWRtaW4_iNofAsbInAInYAFwkmdi_1oVMxI" \
-X POST http://localhost:8001/someServerID/_synapse/admin/v2/users/@testuser:synapse`

Get user info. Handles existing and non-existing users:

curl -i --header "Authorization: Bearer syt_YWRtaW4_iNofAsbInAInYAFwkmdi_1oVMxI" \
-X GET http://localhost:8001/someServerID/_synapse/admin/v2/users/@testuser:synapse

Create and update users:

curl -i --header "Authorization: Bearer syt_YWRtaW4_iNofAsbInAInYAFwkmdi_1oVMxI" \
-X PUT \
-d '{"displayname":"aSomeone new","threepids":[{"medium":"email","address":"aaanewuser@bar.com"}],"external_ids":[{"auth_provider":"oidc-keycloak","external_id":"43b3b9f9-4100-413f-9797-223b067b6e7e"}]}' \
http://localhost:8001/someServerID/_synapse/admin/v2/users/@anewuser:synapse

Automated tests

You need to define TEST_COMMUNICATION_MATRIX_MOCK_SERVER in your config.php when running automated tests like PHPUnit and Behat. Otherwise, most of the Matrix tests will be marked skipped.

For example, add the following to your config.php after the $CFG->wwwroot line:

define('TEST_COMMUNICATION_MATRIX_MOCK_SERVER', "http://localhost:8001/hash" . sha1($CFG->wwwroot));

Local development

• Symphony : wget https://get.symfony.com/cli/installer -O - | bash
• PHP SQLLite3 : example sudo apt install php7.4-sqlite3

Check requirements:

cd application
symfony check:requirements

Set up the db:

php bin/console doctrine:database:drop --force
php bin/console doctrine:schema:create

Run the project:

symfony server:start --port=8001 --no-tls --allow-http

Debugging:

XDEBUG_SESSION=1 symfony server:start --port=8001 --no-tls --allow-http

Notes:

• The database is intended to be disposable. Migrations are not guaranteed to work. Please be prepared to drop and recreate the database.

Publishing status

Note : if you want to publish on your own repository (being Docker Hub or Git Container Registry), you need to define the following secrets following secrets :

• DOCKERHUB_OWNER
• DOCKERHUB_TOKEN
• DOCKERHUB_USERNAME
• GH_OWNER
