Jenkins+Groovy+ActiveChoiceParameter : Rendering dynamic parameter by reading only keys from property file

Create new property file

• Create new property file namely as “test_prop.properties” and stored in any location. Here I have stored in “D:” drive
• Property file location: “D:\test\test_prop.properties”
• Property file has key=value pair concept. Here “keys” are our Test module names, “Values” are related Test case names for that module.

property file: key=value pair

 

Read Keys (Test Module Name) from property file

• Go to Jenkins job configure page
• Select “This build is parameterized” plugin
• Select “Active choice parameter”
• Give Name = Test_Module and select “Groovy Script” option
• Copy below groovy code into that groovy script text area
• Change property file location based on your drive (if it is Linux, change accordingly)
• Select choice type like how to appear in Jenkins UI like whether Check-box/single-select/multi-select….

Groovy Code:

//START
println “Starting Test_Module Script !!!”

//define property object//
def props = new Properties()
//initialize property file path//
def stream = new FileInputStream(“D:/test/test_prop.properties”)
try {
//load property file//
props.load(stream)
} finally {
//once loaded close the stream//
stream.close()
}
//get only property keys and convert into string array//
def parameters=props.keySet() as String[];

//for sorting
parameters= parameters.sort { it.size() }

//def values = parameters.split(‘,’)//

//convert string array into list
def var = Arrays.asList(parameters)

//just print list
System.out.println(var)

//return list to dropDown
return var

//END

• Finally save the configuration page
• Verify saved script in Jenkins UI by clicking “Build with Parameters”
