Masking credentials in Jenkins

Provar now supports execution on Jenkins without needing to check the Provar .secrets file into GitHub. This is to reduce exposure of the credentials used in Test Case execution. The solution is to use Jenkins’ credentials plugin to set up the passwords and security tokens as environment variables.

Create credentials

Go to Jenkins (menu) and choose Credentials.

Create a new user and password credentials. Once it’s created, copy its credentials ID. This is a hash which is used by Jenkins to identify these specific credentials.

Create and configure your new build job

Create a new item (new job), name it, and select Freestyle project or any other.

After installing the plugins, you will now have a new option under Build Environment which is called Use secret text(s) or file(s). Tick this option and a new box will appear: Binding and underneath it Add:

Click Add and choose Username and password (separated):

A new box will appear. Here you can enter the variable name which will hold the real username as in the credentials. You can also enter the variable name for the password which will hold the real password as in the credentials:
