Hi everyone,,

I am trying write the test method for the follwing apex class..

i am get 28% of code coverage..please help in this......for getting more than 75% code coverage..

.

My apex class is::

public class search {

public List<student__c> students{get;set;}
public List<student__c> getstudents(){
return students;
}
public student__c getstudent(){
Id id=system.currentpagereference().getparameters().get('id');
return id == null ? new student__c() : [SELECT Id, Name
FROM Student__c
WHERE Id = :id];
}
public String studentname { get; set; }

public String studentId { get; set; }

public PageReference search() {


if(studentId.length()>0)
{
string stdid='select id, name,Student_Name__c,Email_ID__c,Phone_Number__c from student__C where name=:studentId';
students=Database.Query(stdid);
if(students.size()==0)
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.WARNING,'Student Id Not Found'));
return null;
}
if(studentname.length()>0)
{
string stdname='select id,name,Student_Name__c,Email_ID__c,Phone_Number__c from student__C where student_name__C LIKE \'' + Studentname+ '%\'';
students=Database.Query(stdname);
if(students.size()==0)
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.WARNING,'Student Name Not Found'));
return null;
}
if((studentId.length()>0)&&(studentname.length()>0))
{
string std='select id,name,Student_Name__c from student__C,Email_ID__c,Phone_Number__c where name=:studentId';
students=Database.Query(std);
return null;
}
else
{
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.WARNING,'Please Enter Any Value'));
return null;
}
}
}

Test Class

@istest
public class testMyPage {
static testMethod void myPage_Test()
{
//Test converage for the myPage visualforce page
PageReference pageRef = Page.search_student;
Test.setCurrentPageReference(pageRef);
// create an instance of the controller
search myPageCon = new search();
//try calling methods/properties of the controller in all possible scenarios
// to get the best coverage.
List<student__c> std = myPageCon.getstudents();
//test when type == null
myPageCon.search();
mypagecon.studentname='b';
myPageCon.getstudents();
}
}

thanks in advance........

Regards.
