JMeter and Azure Load Testing using AD Authentication - unable to read Key Vault Secrets

I have a JMeter test that uses Azure AD authentication using username/password. The JMeter test works fine when the Username and Password are read from Excel or hard coded.

I need to run this test in Azure Load Test and have created a Key Vault in Azure with the credentials but unable to get my test to read the secrets.

I have posted snippets of my JMeter test below if anyone can have a look please, I think there is maybe something missing in one of the sections? If this looks correct then probably an issue with the Azure set up. I've stripped out the client_id, tenant_id, etc. in the below code.

The secrets in Azure Key Vault are named LoadTestUsername and LoadTestPassword.

Solution

  • As per the plugin documentation:

    How to install

    Download jmeter-plugins-azure-load-testing-stub-?.?.?.jar file from latest release and put it into lib/ext directory of JMeter (e.g. /usr/local/jmeter/lib/ext), then restart JMeter.

    It will allow you to use Functions Helper Dialog to generate __GetSecret() function syntax however I doubt you will be able to use it locally but it will run successfully in Azure.
