使用docker做UI自动化测试

在devops模式下让我们不得不对CICD进行重视，如何在服务容器化的部署方式下引入自动化测试即是关键。

目标：docker+selenium+python完成分布式UI自动化

基本思路：

①测试运行的浏览器环境是关键，能支持多线程分布式测试非selenium grid不可，试试开源容器镜像 dosel/zalenium

②单独给测试代码做1个容器，使用dockerfile构建成镜像，注意：提前准备私有仓库的基础镜像，基础镜像就包括我们所需的必要依赖

③从自动化测试容器里剥离出allure服务，使用开源容器镜像frankescobar/allure-docker-service/ui能更优美的查看allure报告

接下来开工：

1. 在基础镜像上简单编译

构建自动化测试代码的镜像

FROM xxxxxxxxxxx
ADD . autotest
ENV INSTALL_PATH /autotest
WORKDIR $INSTALL_PATH
COPY . .
EXPOSE 8000
RUN pip install -r requirements.txt
CMD ["/bin/bash"]
#CMD python run.py

2. 编写docker-compose.yaml部署浏览器运行环境容器、allure容器、自动化测试容器

# yaml配置
version: \'3\'
services:
  autotest:
    build: ./
    volumes:
      - ${PWD}/report/allure_result:/autotest/report/allure_reslut
    links:
      - zalenium:zalenium
    depends_on:
      - zalenium
    cap_add:
      - ALL
    entrypoint: >
      /bin/sh -c \'
      sleep 6;
      echo "start autotest";
      python run.py;
      \'
    container_name: autotest
    stdin_open: true
    tty: true
    privileged: true

  zalenium:
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /tmp/videos:/home/seluser/videos
    ports:
      - 4444:4444
    image:  dosel/zalenium
    container_name: zalenium
    privileged: true
    stdin_open: true
    tty: true
    command:
      - start
  allure:
    image: "frankescobar/allure-docker-service"
    environment:
      CHECK_RESULTS_EVERY_SECONDS: 1
      KEEP_HISTORY: 1
    ports:
      - "5050:5050"
    volumes:
      - ${PWD}/report/allure_result:/app/allure-results
      - ${PWD}/report/allure_html:/app/default-report
    user: root
  allure-ui:
    image: "frankescobar/allure-docker-service-ui"
    environment:
      ALLURE_DOCKER_PUBLIC_API_URL: "http://127.0.0.1:5050"
      ALLURE_DOCKER_PUBLIC_API_URL_PREFIX: ""
    ports:
      - "5252:5252"

3、docker-compose up启动，启动即运行测试代码

4、查看allure报告----访问localhost:5252

写在最后

还在朝着使用k8s批量执行测试用例学习中~~~
