## php.ini
|

PHP settings are defined in:
|
||||
|
||||
- a main configuration file, usually found under `/etc/php5/php.ini`; some distributions provide different configuration environments, e.g.
|
||||
- `/etc/php5/php.ini` - used when running console scripts
|
||||
- `/etc/php5/apache2/php.ini` - used when a client requests PHP resources from Apache
|
||||
- `/etc/php5/php-fpm.conf` - used when PHP requests are proxied to PHP-FPM
|
||||
- a main configuration file, usually found under `/etc/php/$php_version/php.ini`; some distributions provide different configuration environments, e.g.
|
||||
- `/etc/php/$php_version/cli/php.ini` - used when running console scripts

|

- `/etc/php/$php_version/php-fpm.conf` - used when PHP requests are proxied to PHP-FPM

## Running tests inside Docker containers
|
||||
|
||||
Read first:

||||

||||
- [Docker 101](docker/docker-101.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

### Setup your environment for 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.

## Setup a testing environment
|
||||
|
||||
### Install composer
|
||||
|
||||
You can either use:
|
||||
|
||||
- a system-wide version, e.g. installed through your distro's package manager
|
||||
- a local version, downloadable [here](https://getcomposer.org/download/).
|
||||
- a system-wide version, e.g. installed through your distro's package manager (eg. `sudo apt install composer`)
|
||||
- a local version, downloadable [here](https://getcomposer.org/download/). To update a local composer installation, run `php composer.phar self-update`
|
||||
|
||||
```bash
|
||||
# system-wide version
|
||||
$ composer install
|
||||
$ composer update
|
||||
|
||||
# local version
|
||||
$ php composer.phar self-update
|
||||
$ php composer.phar install
|
||||
$ php composer.phar update
|
||||
```

#### Install and enable Xdebug to generate PHPUnit coverage reports
|
||||
### Install Xdebug
|
||||
|
||||
See http://xdebug.org/docs/install
|
||||
Xdebug must be installed and enable for PHPUnit to generate coverage reports. See http://xdebug.org/docs/install.
|
||||
|
||||
For Debian-based distros:
|
||||
```bash
|
||||
$ aptitude install php5-xdebug
|
||||
```
|
||||
For ArchLinux:
|
||||
```bash
|
||||
# for Debian-based distributions
|
||||
$ aptitude install php-xdebug
|
||||
|
||||
# for ArchLinux:
|
||||
$ pacman -S xdebug
|
||||
```
|
||||
|
||||
Then add the following line to `/etc/php/php.ini`:
|
||||
Then add the following line to `/etc/php/<PHP_VERSION>/cli/php.ini`:

#### Run unit tests
|
||||
## Run unit tests
|
||||
|
||||
Successful test suite:
|
||||
```bash
|
||||
$ make test
|
||||
Run `make test` and ensure tests return `OK`. If tests return failures, refer to PHPUnit messages and fix your code/tests accordingly.
