Note: I have modified the Apex class for using @TestVisible Annotation and its working while using with Private method. But want to check whether the Private class can be access via Test class method itself.

Accessing Apex Class'es Private methods from Test Methods

Can you help me to solve the issue and understand it better as I am new to Coding world.

I know the issue is because the Apex Class Method's Access modifier "Private" causing the trouble, as I am not able to access it from from Test Methods in Test class

Apex Class [Method DateWithin30Days is Private]

public class verifyDate{

    public static Date CheckDates(Date date1, Date date2){
    if(DateWithin30Days(date1,date2))
        return date2;
    else
        return SetEndOfMonthDate(date1);
    }
    
    private static Boolean DateWithin30Days(Date date1, Date date2){ //Private
    Date date30Days = date1.addDays(30); 
    if( date2 > date30Days) 
        return false; 
    else 
        return true; 
    } 
}

Test Class [Test method - verifyDate.DateWithin30Days(dt1, dt2) throwing error]

Error Method is not visible: verifyDate.DateWithin30Days(Date, Date)

@IsTest
public class TestVerifyDate {   
    @IsTest 
    static void checkDatesTest(){
        Date Dt1 = Date.today();
        Date Dt2 = Date.today()+20;
        Date Dt = verifyDate.CheckDates(Dt1, Dt2);
        system.assertEquals(Dt2, Dt);
        Dt2      = Date.today()+40;
               
        Dt = verifyDate.CheckDates(Dt1, Dt2);
        system.assertEquals(Dt1.addMonths(1).toStartofMonth().addDays(-1),Dt);
    }
    
    @IsTest 
    static void DateWithin30DaysTest(){
        Date Dt1 = Date.today()+40;
        Date Dt2 = Date.today();
        Boolean Flip1 = verifyDate.DateWithin30Days(dt1, dt2);//Error
        system.assertEquals(False, Flip1);
        
        Dt1 = Date.today();
        Dt2 = Date.today()+90;
        Boolean Flip2 = verifyDate.DateWithin30Days(dt1, dt2);//Error
        system.assertEquals(False, Flip2);        
    }
}

can you help me to understand, how can I access the Private Apex Class method DateWithin30Days from Test Class Method DateWithin30DaysTest(). Please let me know what modification I need to do in Test Class method to achieve this?
