Capture Network logs using WebdriverIO

Capturing network logs is something that is key to complete automation.

Often testers are left with the black box of not knowing when a call is being made while going the automation route, with this tool WebdriverIO using the Chrome dev tools protocol via puppeteer it becomes easy for us to achieve that.

We can achieve automation of request analysis and also verify if the requests are made at the right place.

How to do it with WebdriverIO

Ensure you are running this with Chrome browser as this is not available for all the browsers

There are no additional changes required in your wdio.conf.js file

There are no additional libraries required as well

For you to capture a specific type of requests the control lies in browser.mock section

Example for when you want to capture all GET calls

    var output = browser.mock('**',{method:'get'})
    browser.url('https://reqres.in')
Enter fullscreen mode Exit fullscreen mode

Example for when you want to capture all POST calls

    var output = browser.mock('**',{method:'post'})
    browser.url('https://reqres.in')
Enter fullscreen mode Exit fullscreen mode

Example for when you want to capture any POST calls that end with login in the request URL

    var output1 = browser.mock('**/login',{method:'post'})
    browser.url('https://the-internet.herokuapp.com/login')
Enter fullscreen mode Exit fullscreen mode

Example for when you want to capture any POST calls that end with authenticate in the request URL

    var output2 = browser.mock('**/authenticate',{method:'post'})
    browser.url('https://the-internet.herokuapp.com/login')
Enter fullscreen mode Exit fullscreen mode

Example for when you want to capture any GET calls that end with api/users/2 in the request URL

    var output3 = browser.mock('**/api/users/2',{method:'get'})
    browser.url('https://reqres.in')
Enter fullscreen mode Exit fullscreen mode

Note: Once you specify a URL to capture, it will capture all the calls that are made let's say if you made 5 calls all 5 will be captured as a separate object inside that variable in JSON format.

In this video below I have gone about explaining all of the above scenarios and how to automate them. Hope you'll like it
