I am unable to get code coverage for Cancel button(which resets the entire page).

Hi all,

I am unable to create the test class for cancel button. I tried but got error 
 Argument 1 cannot be null.
Please provide the test class for following code

   public pagereference cancel()
    {
     
       PageReference reqPageRef = new PageReference(ApexPages.currentPage().getParameters().get('retURL')); 
       reqPageRef.setRedirect(true);  
       return reqPageRef;
    }

Thanks

Hi Anish,

You can try this :
Note: you should update here accordingly 
@isTest private class TestClass {
    @isTest static void test1() {
        //VF Page is being referenced here and url is passed
        PageReference pageRef = Page.<You Page Name Here>;
        pageRef.getParameters().put('retURL','https://login.salesforce.com/');
        Test.setCurrentPageReference(pageRef);
        Test.startTest();
            <Your Class Name> objClass = new <Your Class Name>();
            objClass.cancel();
        Test.stopTest();
    }
}

Thanks
Niraj

YOU Can call this method in test class as below

<YOUR_CONTROLLER_INSTANCE_REF>.cancel();

like 
MyController myCon = new MyController();
myCon.cancel();
