我正在通过docker运行webdriverIO(https://github.com/hulilabs/webdriverio)测试:
docker-compose run --rm webdriverio wdio
现在我需要使用此命令(ENV?)设置一个可以在测试文件中使用的变量。
describe('my awesome website', function () {
it('should do some chai assertions', function () {
browser.url(url) // <-- I need to set the variable (dev vs. prod)
browser.getTitle().should.be.equal('Website title')
})
})
我该怎么做?
配置
我的 wdio.conf.js :
exports.config = {
host: 'hub',
port: 4444,
specs: [
'./specs/**/*.js'
],
capabilities: [
{ browserName: 'chrome' },
{ browserName: 'firefox' }
]
}
我的 docker-compose.yml 如下所示:
version: '2'
services:
webdriverio:
image: huli/webdriverio:latest
depends_on:
- chrome
- firefox
- hub
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=4444
volumes:
- /app:/app
hub:
image: selenium/hub
ports:
- 4444:4444
firefox:
image: selenium/node-firefox
ports:
- 5900
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=4444
depends_on:
- hub
chrome:
image: selenium/node-chrome
ports:
- 5900
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=4444
depends_on:
- hub
答案 0 :(得分:2)
首先,您需要将ENV变量设置为docker-compose.yml
services:
webdriverio:
image: huli/webdriverio:latest
depends_on:
- chrome
- firefox
- hub
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=4444
- APP_PROFILE=dev # <- here new variable
volumes:
- /app:/app
然后你需要在你的应用中阅读这个变量
describe('my awesome website', function () {
it('should do some chai assertions', function () {
browser.url(process.env.APP_PROFILE)
browser.getTitle().should.be.equal('Website title')
})
})
此外,在Dockerfile
中,您可以将ENV变量设置为默认值:
ENV APP_PROFILE=prod
