Code Coverage on Apex Class used as Visualforce Page Controller

I have a custom Visualforce page that is used to create an interactive report for our sales teams.  Once a sales rep clicks on custom tab, it brings them to the Visualforce page, which in turn calls the Apex class.  The Apex class queries the rep's opportunities and puts them into a list.  The Visualforce page uses that list and some CSS and Javascript to render an interactive report for the rep.

My question is how would I get code coverage for the Apex class as it is not triggered by a record and does not have a DML statement?  It simply calls a list of records in a list and displays it to the user.

You can generate the data and then pass it through via your test.  For example

NoDMLClass.cls 
public class NoDMLClass {
    public String doSomething(List<Account> accts) {
        // do something

        return 'I did something';
    }
}

NoDMLClass_Test.cls 
@isTest
private class NoDMLClass_Test {
    static testMethod void doSomething_test() {
        List<Account> accountList = new List<Account> {
            new Account(...),
            new Account(...)
        }

        insert accountList;

        Test.startTest();

        String result = NoDMLClass.doSomething(accountList);

        Test.stopTest();

        System.assertEquals(
            'I did something',
            result,
            'Did not get the right result back'
        );
    }
}

Is this the type of thing you're talking about?

@pcon, below is my specific Visualforce page and Apex controller class.

So for your code, you'll want to insert a bunch of OpportunityLineItem records (and their required parents) that meet your where criteria.  Then inside your startTest/stopTest call your getData method and your Result method.
  
static testMethod pivotTest() {
    // Code to insert accounts, opportunities, opportunity line items, etc

    Test.startTest();

    Pivot p = new Pivot();

    String result = p.getData();

    System.assertEquals(
        'visibility: visible',
        pivot.getPivot,
        'Did not get the right pivot css'
    );

    p.result();

    System.assertEquals(
        'visibility: hidden',
        pivot.getPivot,
        'Did not get the right pivot css'
    );
    System.assertEquals(
        'Save successfully  ',
        pivot.returnValue,
        'Did not get the right return value'
    );

    Test.stopTest();

    List<Pivot.PiviotData> pivotData;

    // Code to deserialize result JSON into pivotData
    // Code to make sure the PivotData was set right
}
