Proxy Setup

You can tunnel two different types of request through a proxy:

  • connection between your test script and the browser driver (or WebDriver endpoint)
  • connection between the browser and the internet

Proxy Between Driver And Test​

If your company has a corporate proxy (e.g. on http://my.corp.proxy.com:9090) for all outgoing requests, follow the below steps to install and configure global-agent.

Install global-agent​

npm install global-agent --save-dev

Add global-agent bootstrap to your config file​

Add the following require statement to the top of your config file.

wdio.conf.js
require('global-agent/bootstrap')

exports.config = {
// ...
}

Set global-agent environment variables​

Before you start the test, make sure you've exported the variable in the terminal, like so:

export GLOBAL_AGENT_HTTP_PROXY=http://my.corp.proxy.com:9090
wdio wdio.conf.js

You can exclude URLs from the proxy by exporting the variable, like so:

export GLOBAL_AGENT_HTTP_PROXY=http://my.corp.proxy.com:9090
export GLOBAL_AGENT_NO_PROXY='.foo.com'
wdio wdio.conf.js

If necessary, you can specify GLOBAL_AGENT_HTTPS_PROXY to route HTTPS traffic through a different proxy than HTTP traffic.

export GLOBAL_AGENT_HTTP_PROXY=http://my.corp.proxy.com:9090
export GLOBAL_AGENT_HTTPS_PROXY=http://my.corp.proxy.com:9091
wdio wdio.wdio.conf.js

GLOBAL_AGENT_HTTP_PROXY is used for both HTTP and HTTPS requests if GLOBAL_AGENT_HTTPS_PROXY is not set.

If you use Sauce Connect Proxy, start it via:

sc -u $SAUCE_USERNAME -k $SAUCE_ACCESS_KEY --no-autodetect -p http://my.corp.proxy.com:9090

Proxy Between Browser And Internet​

In order to tunnel the connection between the browser and the internet, you can set up a proxy which can be useful to (for example) capture network information and other data with tools like BrowserMob Proxy.

The proxy parameters can be applied via the standard capabilities the following way:

wdio.conf.js
exports.config = {
// ...
capabilities: [{
browserName: 'chrome',
// ...
proxy: {
proxyType: "manual",
httpProxy: "corporate.proxy:8080",
socksUsername: "codeceptjs",
socksPassword: "secret",
noProxy: "127.0.0.1,localhost"
},
// ...
}],
// ...
}
