Stub function for Azure Load Testing - can't retrieve credentials from both JMeter Properties and Environment variables

[danzone]

Hi all, I've installed Stub function for Azure Load Testing plugin, with following info:

• Stub function for Azure Load Testing plugin: 0.1.0
• Apache JMeter: 5.6.3
• O.S. Windows 11
• JVM: OpenJDK 64-Bit Server 21.0.8

I configured the store type in user.properties:

azure_load_testing_stub.get_secret.mySecretName.store_type=environment_variable

Then I set up an environment variable in my Windows 11 laptop:

$env:AZURE_LOAD_TESTING_STUB_GET_SECRET_mySecretName='MY_SECRET_PASSWORD'

Then I configured my script to use these credentials within Authorization Manager:

but the secret value isn't loaded from env variable (I extracted from header request the Authorization header, Base64 decoded it and the password is empty).

I tried also to user the JMeter properties approach, configuring it in user.properties as follows:

azure_load_testing_stub.get_secret.mySecretName.store_type=jmeter_properties
azure_load_testing_stub.get_secret.mySecretName.value=MY_SECRET_PASSWORD

restarted JMeter, but nothing change: no secret value is extracted from user.properties. I also tried to use jmeter.properties file instead of user.properties, but nothing change.

Am I missing something?

Thanks in advance

Hi @danzone ,

The GetSecret function is not available in the HTTP Authorization Manager. This applies not only to this plugin but also to Azure Load Testing.
Assign GetSecret to a variable in “User Defined variables” and reference it from the HTTP Authorization Manager.

Thanks

Hi, @kuniteru , thank you for your answers. Actually I tried to put it in a User defined variables and it works. The problem is that I need to have different passwords for the various virtual users I configure in the system. I don't want to store their credentials in a CSV file, so I stored in the csv just the userid and the secret name for each user, storing then in the user.properties the password. But User Defined Variables store a value shared across all virtual users and this is not the right solution. I tried also to use User Parameters, but it seems that GetSecret doesn't store the secret within User Parameters. Is there a way to invoke GetSeecret from within a JSR Groovy Pre-processor (or Beanshell pre-processor)? In thyis way I could store the secret in a variable local to current thread and then use it within the Authorization Manager.
Thanks in advance.
