How can we do build test class for the pagereference method?

Hi Mohit,

You can refer to below code:

@isTest
private class testMyController{

private static testMethod void testAutoRun() {

test.startTest();
PageReference pageRef = Page.yourPageName;
Account acc = new Account(Name=’Abce’);
insert acc;
Opportunity testOppty = new Opportunity();
testOppty.name=’testOppty’;
testOppty.AccountId=acc.id;
testOppty.StageName=’Open’;
testOppty.CloseDate=System.today();
insert testOppty;
Test.setCurrentPage(pageRef);
pageRef.getParameters().put(‘id’,testOppty.id);
ApexPages.StandardController sc = new ApexPages.standardController(testOppty);
Myclass controller = new Myclass(sc);
System.assertNotEquals(null,controller.autoRun());

test.stopTest();
}

}

Thanks
