How to cover pagereference method in test class

I have a method like page reference method in my class. How to cover the pagereference method in test class. all the other methods were covered except the pagereference method. I tried like:

PageReference pageRef = Page.myclassname; Test.setCurrentPage(pageRef); pageRef.getParameters().put('timezonevar',var);

but of no use; my methods is like:

public PageReference mymethod() < //here using some variables which are used in the standard controller constructor. //all the logic goes here, return null; >

If your method always returns null then there is no need to return PageReference. You can make it a void-return method instead. Perhaps it would help more if you posted what the logic is. What is it that you want to test? The return value of the method or the logic it executes?

If you are using custom controller

//Create test records PageReference pageRef = Page.myclassname; Test.setCurrentPage(pageRef); pageRef.getParameters().put('timezonevar',var); //init controller CustomCtrl objCtrl = new CustomCtrl(); //Call pageRef mymethod PageReference objPageRef = objCtrl.mymethod(); //put system asserts System.assertEquals (null,pageRef);

If you are using StandardController

//first create record PageReference pageRef = Page.myclassname; Test.setCurrentPage(pageRef); pageRef.getParameters().put('timezonevar',var); // testRecord is your record ApexPages.StandardController stc = new ApexPages.StandardController(testRecord); //Call controller CustomCtrl objCtrl = new CustomCtrl(stc); //Call pageRef mymethod PageReference objPageRef = objCtrl.mymethod(); //put system asserts System.assertEquals (null,pageRef);
