## Running tests inside Docker containers
Read first:
- [Docker 101](docker/docker-101.md)
- [Docker resources](docker/resources.md)
- [Unit tests](Unit-tests.md)
### Docker test images
Test Dockerfiles are located under `tests/docker/<distribution>/Dockerfile`,
and can be used to build Docker images to run Shaarli test suites under common
Linux environments.
Dockerfiles are provided for the following environments:
- `alpine36` - [Alpine 3.6](https://www.alpinelinux.org/downloads/)
- `debian8` - [Debian 8 Jessie](https://www.debian.org/DebianJessie) (oldstable)
- `debian9` - [Debian 9 Stretch](https://wiki.debian.org/DebianStretch) (stable)
- `ubuntu16` - [Ubuntu 16.04 Xenial Xerus](http://releases.ubuntu.com/16.04/) (LTS)
What's behind the curtains:
- each image provides:
- a base Linux OS
- Shaarli PHP dependencies (OS packages)
- test PHP dependencies (OS packages)
- Composer
- the local workspace is mapped to the container's `/shaarli/` directory,
- the files are rsync'd so tests are run using a standard Linux user account
(running tests as `root` would bypass permission checks and may hide issues)
- the tests are run inside the container.
### Building test images
```bash
# build the Debian 9 Docker image
$ cd /path/to/shaarli
$ cd tests/docker/debian9
$ docker build -t shaarli-test:debian9 .
```
### Running tests
```bash
$ cd /path/to/shaarli
# install/update 3rd-party test dependencies
$ composer install --prefer-dist
# run tests using the freshly built image
$ docker run -v $PWD:/shaarli shaarli-test:debian9 docker_test
# run the full test campaign
$ docker run -v $PWD:/shaarli shaarli-test:debian9 docker_all_tests
```
