You can customize it by passing `--adminuser='myusername'` ## Use containers for running behat tests for the mobile app In order to run Behat tests for the mobile app, you need to install the [local_moodlemobileapp](https://github.com/moodlehq/moodle-local_moodlemobileapp) plugin in your Moodle site. Everything else should be the same as running standard Behat tests for Moodle. Make sure to filter tests using the `@app` tag. The Behat tests will be run against a container serving the mobile application, you have two options here: 1. Use a docker image that includes the application code. You need to specify the `MOODLE_DOCKER_APP_VERSION` env variable and the [moodlehq/moodleapp](https://hub.docker.com/r/moodlehq/moodleapp) image will be downloaded from docker hub. 2. Use a local copy of the application code and serve it through docker, similar to how the Moodle site is being served. Set the `MOODLE_DOCKER_APP_PATH` env variable to the codebase in you file system. This will assume that you've already initialized the app calling `npm install` and `npm run setup` locally. For both options, you also need to set `MOODLE_DOCKER_BROWSER` to "chrome". ```bash # Install local_moodlemobileapp plugin git clone git://github.com/moodlehq/moodle-local_moodlemobileapp "$MOODLE_DOCKER_WWWROOT/local/moodlemobileapp" # Initialize behat environment bin/moodle-docker-compose exec webserver php admin/tool/behat/cli/init.php # [..] # Run behat tests bin/moodle-docker-compose exec -u www-data webserver php admin/tool/behat/cli/run.php --tags="@app&&@mod_login" Running single behat site: Moodle 4.0dev (Build: 20200615), a2b286ce176fbe361f0889abc8f30f043cd664ae Php: 7.2.30, pgsql: 11.8 (Debian 11.8-1.pgdg90+1), OS: Linux 5.3.0-61-generic x86_64 Server OS "Linux", Browser: "chrome" Browser specific fixes have been applied. See http://docs.moodle.org/dev/Acceptance_testing#Browser_specific_fixes Started at 13-07-2020, 18:34 ..................................................................... 4 scenarios (4 passed) 69 steps (69 passed) 3m3.17s (55.02Mb) ``` If you are going with the second option, this *can* be used for local development of the mobile app, given that the `moodleapp` container serves the app on the local 8100 port. However, this is intended to run Behat tests that require interacting with a local Moodle environment. Normal development should be easier calling `npm start` in the host system. By all means, if you don't want to have npm installed locally you can go full docker executing the following commands before starting the containers: ``` docker run --volume $MOODLE_DOCKER_APP_PATH:/app --workdir /app node:11 npm install docker run --volume $MOODLE_DOCKER_APP_PATH:/app --workdir /app node:11 npm run setup ``` ## Using VNC to view behat tests If `MOODLE_DOCKER_SELENIUM_VNC_PORT` is defined, selenium will expose a VNC session on the port specified so behat tests can be viewed in progress. For example, if you set `MOODLE_DOCKER_SELENIUM_VNC_PORT` to 5900.. 1. Download a VNC client: https://www.realvnc.com/en/connect/download/viewer/ 2. With the containers running, enter 0.0.0.0:5900 as the port in VNC Viewer. You will be prompted for a password. The password is 'secret'. 3. You should be able to see an empty Desktop. When you run any Behat tests a browser will popup and you will see the tests execute. ## Stop and restart containers `bin/moodle-docker-compose down` which was used above after using the containers stops and destroys the containers. If you want to use your containers continuously for manual testing or development without starting them up from scratch everytime you use them, you can also just stop without destroying them. With this approach, you can restart your containers sometime later, they will keep their data and won't be destroyed completely until you run `bin/moodle-docker-compose down`. ```bash # Stop containers bin/moodle-docker-compose stop # Restart containers bin/moodle-docker-compose start ``` ## Environment variables You can change the configuration of the docker images by setting various environment variables before calling `bin/moodle-docker-compose up`. | Environment Variable | Mandatory | Allowed values | Default value | Notes | |-------------------------------------------|-----------|---------------------------------------|---------------|------------------------------------------------------------------------------| | `MOODLE_DOCKER_DB` | yes | pgsql, mariadb, mysql, mssql, oracle | none | The database server to run against | | `MOODLE_DOCKER_WWWROOT` | yes | path on your file system | none | The path to the Moodle codebase you intend to test | | `MOODLE_DOCKER_PHP_VERSION` | no | 7.4, 7.3, 7.2, 7.1, 7.0, 5.6 | 7.3 | The php version to use | | `MOODLE_DOCKER_BROWSER` | no | firefox, chrome | firefox | The browser to run Behat against | | `MOODLE_DOCKER_PHPUNIT_EXTERNAL_SERVICES` | no | any value | not set | If set, dependencies for memcached, redis, solr, and openldap are added | | `MOODLE_DOCKER_WEB_HOST` | no | any valid hostname | localhost | The hostname for web | | `MOODLE_DOCKER_WEB_PORT` | no | any integer value (or bind_ip:integer)| 127.0.0.1:8000| The port number for web. If set to 0, no port is used.
If you want to bind to any host IP different from the default 127.0.0.1, you can specify it with the bind_ip:port format (0.0.0.0 means bind to all) | | `MOODLE_DOCKER_SELENIUM_VNC_PORT` | no | any integer value (or bind_ip:integer)| not set | If set, the selenium node will expose a vnc session on the port specified. Similar to MOODLE_DOCKER_WEB_PORT, you can optionally define the host IP to bind to. If you just set the port, VNC binds to 127.0.0.1 | | `MOODLE_DOCKER_APP_PATH` | no | path on your file system | not set | If set and the chrome browser is selected, it will start an instance of the Moodle app from your local codebase | | `MOODLE_DOCKER_APP_VERSION` | no | next, latest, or an app version number| not set | If set will start an instance of the Moodle app if the chrome browser is selected | ## Using XDebug for live debugging The XDebug PHP Extension is not included in this setup and there are reasons not to include it by default. However, if you want to work with XDebug, especially for live debugging, you can add XDebug to a running webserver container easily: ``` # Install XDebug extension with PECL moodle-docker-compose exec webserver pecl install xdebug # Set some wise setting for live debugging - change this as needed read -r -d '' conf <<'EOF' ; Settings for Xdebug Docker configuration xdebug.coverage_enable = 0 xdebug.default_enable = 0 xdebug.cli_color = 2 xdebug.file_link_format = phpstorm://open?%f:%l xdebug.idekey = PHPSTORM xdebug.remote_enable = 1 xdebug.remote_autostart = 1 xdebug.remote_host = host.docker.internal EOF moodle-docker-compose exec webserver bash -c "echo '$conf' >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini" # Enable XDebug extension in Apache moodle-docker-compose exec webserver docker-php-ext-enable xdebug ``` While setting these XDebug settings depending on your local need, please take special care of the value of `xdebug.remote_host` which is needed to connect from the container to the host. The given value `host.docker.internal` is a special DNS name for this purpose within Docker for Windows and Docker for Mac. If you are running on another Docker environment, you might want to try the value `localhost` instead or even set the hostname/IP of the host directly. After these commands, XDebug ist enabled and ready to be used in the webserver container. If you want to disable and re-enable XDebug during the lifetime of the webserver container, you can achieve this with these additional commands: ``` # Disable XDebug extension in Apache and restart the webserver container moodle-docker-compose exec webserver sed -i 's/^zend_extension=/; zend_extension=/' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini moodle-docker-compose restart webserver # Enable XDebug extension in Apache and restart the webserver container moodle-docker-compose exec webserver sed -i 's/^; zend_extension=/zend_extension=/' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini moodle-docker-compose restart webserver ``` ## Advanced usage As can be seen in [bin/moodle-docker-compose](https://github.com/moodlehq/moodle-docker/blob/master/bin/moodle-docker-compose), this repo is just a series of docker-compose configurations and light wrapper which make use of companion docker images. Each part is designed to be reusable and you are encouraged to use the docker[-compose] commands as needed. ## Companion docker images The following Moodle customised docker images are close companions of this project: * [moodle-php-apache](https://github.com/moodlehq/moodle-php-apache): Apache/PHP Environment preconfigured for all Moodle environments * [moodle-db-mssql](https://github.com/moodlehq/moodle-db-mssql): Microsoft SQL Server for Linux configured for Moodle * [moodle-db-oracle](https://github.com/moodlehq/moodle-db-oracle): Oracle XE configured for Moodle ## Contributions Are extremely welcome!
