## 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
|
||||

The testing framework used is [PHPUnit](https://phpunit.de/); it can be installed with [Composer](https://getcomposer.org/), which is a dependency management tool.
