最近使用php开发composer包时，想编写单元测试测试具体方法有没有问题。但是我的开发环境都是基于laradocker搭建的，网上搜了快很多关于docker+phpunit+phpstorm的文章，但是都讲的….。

以下项目是基于laradocker搭建的,已经支持xdebug和swoole等扩展

1. 项目目录介绍

# 本地目录
/Users/hui/Project/PHP/php-tools

# docker镜像中的目录
/var/www/php-tools

2. 安装phpunit

因为我是基于laradocker 搭建的PHP开发环境，laradocker是通过docker-compose 启动服务，如我的服务列表

➜  docker_php_env git:(master) docker-compose ps
         Name                      Command              State              Ports
--------------------------------------------------------------------------------------------
env_docker-in-docker_1   dockerd-entrypoint.sh          Up      2375/tcp, 2376/tcp
env_nginx_1              /docker-entrypoint.sh /bin     Up      0.0.0.0:443->443/tcp,
                         ...                                    0.0.0.0:80->80/tcp,
                                                                0.0.0.0:9900->9900/tcp
env_php-fpm_1            docker-php-entrypoint php-     Up      9000/tcp
                         fpm
env_redis_1              docker-entrypoint.sh redis     Up      0.0.0.0:6379->6379/tcp
                         ...
env_workspace_1          /sbin/my_init                  Up      0.0.0.0:2222->22/tcp

2.1 进入workspace安装

为什么要在workspace中安装？因为我本地没有安装composer,也没有php环境,composer安装过程中经常会检测PHP的某些扩展是否已经安装，而workspace服务中已经安装composer和PHP

# 进入workspace
➜  docker_php_env git:(master) docker-compose exec workspace bash
# 安装

3. 配置phpstorm

3.1 步骤一: 配置CLI Interpreter

点击OK(确认)后

3.2 步骤二: 配置目录映射和网络

注意点:

我在docker-compose.yaml 设置php-fpm走的网络是backend, 配置如下:

...
### PHP-FPM ##############################################
    php-fpm:
      build:
        context: .
        dockerfile: ./php-fpm/Dockerfile
        args:
          - PHP_VERSION=${PHP_VERSION}
      volumes:
        - ./php-fpm/php${PHP_VERSION}.ini:/usr/local/etc/php/php.ini
        - ${APP_CODE_PATH_HOST}:${APP_CODE_PATH_CONTAINER}${APP_CODE_CONTAINER_FLAG}
      expose:
        - "9000"
      extra_hosts:
        - "dockerhost:${DOCKER_HOST_IP}"
      environment:
        - PHP_IDE_CONFIG=${PHP_IDE_CONFIG}
        - DOCKER_HOST=tcp://docker-in-docker:2375
        - FAKETIME=${PHP_FPM_FAKETIME}
      depends_on:
        - workspace
      networks:
        - backend # 这里设置的是网络
      links:
        - docker-in-docker
...

**但是！但是! ! 在docker网络中找不到 !! ** 如下列出我本地的docker网络都有哪些:

➜  docker_php_env git:(master) docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
ad463cc3f333        bridge              bridge              local
b3581c822831        env_backend         bridge              local
62b15b6d0f61        env_frontend        bridge              local
ca0e05f7c6c1        host                host                local
