How to discover the reason for an error in my simple test class?

Question

This is my aura method to retrieve fields for dual list box.

@AuraEnabled
        public static List <String> getProperties(sObject objObject, string sFieldAPI) {
            List < String > lstOptions = new list < String > ();
            Schema.sObjectType objType = objObject.getSObjectType();
            Schema.DescribeSObjectResult objDescribe = objType.getDescribe();
            map <String, Schema.SObjectField> fieldMap = objDescribe.fields.getMap();
            list < Schema.PicklistEntry > values =fieldMap.get(sFieldAPI).getDescribe().getPickListValues();
            for (Schema.PicklistEntry a: values) {
            lstOptions.add(a.getValue());
            }
            lstOptions.sort();
            return lstOptions;
        }

And this is the test class where I'm getting error.

testMethod static void testGetProperties(){
    setupInsertData();
    Test.startTest();
    List<String> Prop = MessageTypeController.getProperties('isArray');
    System.debug('Test Category'+Prop);
    if(Prop!=null){
          System.assertEquals(Prop!=null,true);
    }else{
         System.assertEquals(Prop==null,true);  
    }
    Test.stopTest();
}

The text of the error is:

"Method does not exist or incorrect signature: void getProperties(String)"

it's the getProperties('isArray')? I think parameter is wrong or something else when i save and push code got this error "Method does not exist or incorrect signature: void getProperties(String)" — Hardik Borad, Jun 06 '22 at 10:27
What is the text of the error, like "Division by zero" or "Variable not found"? — halfer, Jun 06 '22 at 10:29
method name is right but incorrect signature i don't understand.. — Hardik Borad, Jun 06 '22 at 10:31
Have you looked at the documentation for the class `MessageTypeController`? — halfer, Jun 06 '22 at 10:35
I assume this code is in Java. Are you using an IDE that can do full type introspection? Perhaps your IDE can tell you what parameters this method takes. — halfer, Jun 06 '22 at 10:36

You / your colleague defined getProperties(sObject objObject, string sFieldAPI) but you're trying to call it with getProperties('isArray'). There's no method with 1 parameter (at least not in the code snippet you pasted).

You probably want to call it with something like

MessageTypeController.getProperties(new Opportunity(), 'StageName');

With this now it's working:

testMethod static void testGetProperties(){
    setupInsertData();
    Test.startTest();
    skyvvasolutions__MessageType__c msg = new skyvvasolutions__MessageType__c();
    List<String> Prop = MessageTypeController.getProperties(msg, 'skyvvasolutions__Properties__c');
    System.debug('Test Category'+Prop);
    if(Prop!=null){
          System.assertEquals(Prop!=null,true);
    }else{
         System.assertEquals(Prop==null,true);  
    }
    Test.stopTest();
}

So... this is with two parameters, as in my answer, right? ;) – eyescream Jun 07 '22 at 07:39
yes it take two parameters but not the way you showed. – Hardik Borad Jun 07 '22 at 08:45
Different how? That you have `skyvvasolutions__MessageType__c msg = new skyvvasolutions__MessageType__c()` in separate line? A variable you don't use anywhere else in the test? Or that you made it run on different sObject? lol – eyescream Jun 07 '22 at 09:10
