How to get jenkins BUILD_NUMBER in webdriverio config file

Question

My automation project is setup in Jenkins pipeline. I am using custom webdriverio service in wdio config file. I tried const buildNum = process.env.BUILD_NUMBER; but it returns null. Also I get this error

Answer 1

I do this in my project:

In the wdio-conf file i have this variable declared above the exports

const buildUrl = process.env.BUILD_URL || '';

In the jenkins, i have the below while triggering the test:

BUILD_URL=${BUILD_URL} npm test

This passes in the URL when triggered from jenkins or assign '' when not triggered from jenkins.

You need to add build step in shell file first as below..

export BUILD_NUMBER=${BUILD_NUMBER}

Then call process.env.BUILD_NUMBER

For Windows bat file add below..

SET BUILD_NUMBER=%BUILD_NUMBER%

Then call process.env.BUILD_NUMBER
