Create Test Class for Process Plugin

Hi,

I created an APEX class that creates a Flow plug-in. I followed the documentation online, I'll post link below. But I cant seem to be able to write a test class that will fully cover the APEX class.

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_process_plugin.htm


CLASS 
global class flowTask implements Process.Plugin{
    
    global Process.PluginResult invoke(Process.PluginRequest request){
        
        string taskCase = (String) request.inputParameters.get('CaseId');
        date taskDate = date.today();
        String description = (String) request.inputParameters.get('subject');
        
        Task myTask = new Task();
        myTask.ActivityDate = taskDate;
		myTask.Description = description;
        myTask.Status = 'Completed';
        myTask.WhatId = taskCase;
        
        insert myTask;
        
        Map<String, Object> result = new Map<String, Object>();
        return new Process.PluginResult(result);
    }
    
    global Process.PluginDescribeResult describe(){
        Process.PluginDescribeResult result = new Process.PluginDescribeResult();
        result.Name = 'flowtaskpluggin';
        result.Tag = 'task';
        result.inputParameters = new List<Process.PluginDescribeResult.inputParameter>{
            new Process.PluginDescribeResult.InputParameter('subject', Process.PluginDescribeResult.ParameterType.STRING, true),
            new Process.PluginDescribeResult.InputParameter('CaseId', Process.PluginDescribeResult.ParameterType.STRING, true)   
        };
            result.outputParameters = new List<Process.PluginDescribeResult.outputParameter>{
                
            };
            return result;
    }

}


TEST 
@isTest
private class flowTaskTest{
    
    static testmethod void flowTaskTest(){
        
        flowTask plugin = new flowTask();
        Map<String, Object> inputParams = new Map<String, Object>();
        string taskNum = '50063000003AEik';		//50063000003AEik-SBX | 500o000000GCryb-PROD
        string taskSub = 'Test Class';
        
        inputParams.put('subject', taskSub);
        inputParams.put('CaseId', taskNum);
        
        Process.PluginRequest request = new Process.PluginRequest(inputParams);
        
        plugin.invoke(request);
    }

}


Im not sure how to test the describe function in the APEX code. Any information is a helpful. 

Thanks,
-Julio Hernandez

Hi Julio,

Below test class should help your test coverage. Ensure you populate all the required case fields in createCase method. 
@isTest
private class flowTaskTest{
    
    private static Case createCase(){
        Case record = new Case();
        record.Subject = 'Test';
        insert record;
        return record;
    }
    static testmethod void flowTaskTest(){
        Case record = createCase();
        flowTask plugin = new flowTask();
        Map<String, Object> inputParams = new Map<String, Object>();
        string taskNum = record.Id;		//50063000003AEik-SBX | 500o000000GCryb-PROD
        string taskSub = 'Test Class';
        
        inputParams.put('subject', taskSub);
        inputParams.put('CaseId', taskNum);
        
        Process.PluginRequest request = new Process.PluginRequest(inputParams);
        
        plugin.invoke(request);
        Process.PluginDescribeResult result = plugin.describe();
    }

}

Thank you very much Lalit. The issue I was having was with the coverage on global Process.PluginDescribeResult describe() function.

This line seems to cover it.
Process.PluginDescribeResult result = plugin.describe();
