How can I pass a variable group in Jmeter using Azure Pipeline?

Question

I need to use the Variable group in the azure pipeline that links to Azure Key Vault secret. The secret will be used to connect to a sql database.

Is there a way th

Answer 1

Since there no such option or checkbox in task of pipeline to directly achieve pass variable value to .jmx file, you can use the Replace token task to achieve the Parameter value replaced.

• Use Azure Key Vault task to download the relevant secrets firstly.

• Add Replace Token task(note: add this task before test step thus the test step can executed with the .jmx file which has received the value), then specify the target files

• Then configure the variable in .jmx file with the format #{parameter name}#:

Note: The parameter name which defined in the .jmx file should same with the variable name which in Azure key Vault. Otherwise, the parameter could not get the value from variable.

This is my source files which exists in my agent locally, you can see that the value was passed successfully:

Using linux sed:

Replace a known token variable in file.jmx with 'sed' as follows: In .jmx add a known token to be replaced as: %SERVER_NAME% Replace your token with an environment variable

- script: |
echo "Replace Servername parameter in file.jmx with $ sed "
sed 's/%SERVER_NAME%/server.com/g' file.jmx > new.jmx
# or replace with a global variable
sed 's/%SERVER_NAME%/'$(SERVER_NAME)'/g' file.jmx > new.jmx

Replacing with sed a value in .jmx

Using Azure variables:

In file.jmx add your Azure global or pipeline local variables, on this case I add the user_name. In jMeter I suggest add a Config Element > Used Defined Variables and add a variable as:

 Name          | Value
 user_name     | ${__groovy( System.getenv("USER_NAME") )}

In case you are passing secret password add the reference in the variables by using the Property option as

Name           | Value
user_password  | ${__P(USER_PASSWORD)}

Set your variable locally on jMeter > bin path as

   set USER_NAME=rmd_test_4

In your jMeter requests, you should use the variable ${user_name} and ${user_password}. Your Azure command should be the same as if you run them locally in your CLI as follows:

   Locally: jmeter -n -t test_flow.jmx -JUSER_PASSWORD=abc123
   Azure:   jmeter -n -t test_flow.jmx -Juser_pwd=$(RMD_TEST_PASS)

I hope this may help
