I need to share few variables between two thread groups in an Apache jmeter project. I found that variables cannot be shared between thread groups and I have to use properties. I have written the below script inside a JSR223 PreProcessor in the first thread group to set the property values. It runs without any exception.
@Grab('org.yaml:snakeyaml:1.17')
import org.yaml.snakeyaml.Yaml;
import org.apache.jmeter.services.FileServer;
String baseDir = FileServer.getFileServer().getBaseDir()
Yaml ymlparser = new Yaml()
Map config = ymlparser.load((baseDir+"/config/tool.yaml" as File).text)
String base_path = baseDir + "/data/" + trafficConfig.find{it.key=="name"}?.value
${__setProperty(basePath, base_path)};
If I log the value of the property 'basePath' from the same JSR223 PreProcessor, it will return the correct value.
Then I'm reading the property value from a JSR223 PreProcessor in the second thread group like below.
${__property(basePath, base_path)}
log.info( base_path );
It will through the below exception in jmeter log.
