Nightwatch Capture Network Traffic

Here is the demo for Nightwatch to capture the network traffic.

Give me a 🌟, if it helps. Thank you! 🤩

How to run this demo

# Install the chromedriver
# Note: the chromedirver version in package.json is 77.0.0. You may need to change it based on your environment
npm install 

# Run the test
nightwatch captureXHRTraffic.js

How it is working

1. Take advantage of the ajaxListener.js

   The js is forked from https://gist.github.com/icodejs/3183154

   This hack will make all the XHR requests as a warn log to console

    {
        "type": "response",
        "syncMode": this.syncMode,
        "method": this.method,
        "url": this.url,
        "requestData": this.requestData,
        "readyState": this.readyState,
        "responseText": this.responseText,
        "responseCode": this.status,
        "responseHeader": this.getAllResponseHeaders()
    }
   

2. Then take advantage of Nightwatch API .getLog

   The .getLog could capture the console warn logs for us

Limitations

This solution only could capture the XHR requests.

If traffic type is fetch, it won't working.

For example, all the requests in https://httpbin.org/ are fetch type, this solution is not working.
