        emailAddresses.add(str.trim());        
      }
    }
    return emailAddresses;
  }
}

My current test class looks like:

@isTest
public class TestReportParser{ 

    public TestReportParser(){ } 

    public static testMethod void MyTestReportParser(){ 
        string jsonString = '{"currency" : "ABC"}';
         List<String> mytestData; 
        ReportParser rpt = new ReportParser(); 
        ReportParser rp = new ReportParser(jsonString); 
        String mydata = rp.getHtmlTable(); 
        mytestData = rp.getHeader(); 
    }
}

  • What are the difficulties you have? What you have tried so far? – highfive May 21 '14 at 6:59
  • let me show you my test class @isTest public class TestReportParser{ public TestReportParser(){ } public static testMethod void MyTestReportParser(){ string jsonString = '{"currency" : "ABC"}'; List<String> mytestData; ReportParser rpt = new ReportParser(); ReportParser rp = new ReportParser(jsonString); String mydata = rp.getHtmlTable(); mytestData = rp.getHeader(); } } this my test class. i am new in salesforce so not get more idea – user1969206 May 21 '14 at 9:54

First read some documentations and try to get a help from them. Below links will help to getting started.

  1. https://developer.salesforce.com/page/An_Introduction_to_Apex_Code_Test_Methods
  2. https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_qs_test.htm

You can set the page reference to your visualforce page from the test class(with the URL parameters as well). Add below code into your test class with relevant updates according to your data.

// Id reportId = 'some report Id';
// Set current page *to Your_VFPage* page and initializing data
   Pagereference ref = Page.*Your_Page*;
   Test.setCurrentPageReference(ref);
   System.currentPageReference().getParameters().put('reportId', reportId);   //  jobSchedule Id parameter for SampleLocationsForSampleCollection VF page

Also if you need to call the controller methods directly simply create an instance of the controller and call the methods to test them.

CustomizedReportController controller = new CustomizedReportController();
controller.initDefaultTheme();
...

But make sure you are handling null occurrences correctly, if not your code will break and your test class will fail.

  • I have tried this thing in my code I got 58% coverage but one error i still getting is "Methods defined as TestMethod do not support getContent call, test skipped" in my "sendEmail();" method. can please help me to solve this error. – user1969206 May 22 '14 at 5:53
  • Before doing a webservice callout, check whether the it's running from a test execution. Check this link salesforce.stackexchange.com/questions/12344/… – highfive May 22 '14 at 5:59
  • i am getting this error when call "ref =controller.sendEmail()" method but this method is not webservice callout method this is normal method and not get any other webservice callout in debug log file. – user1969206 May 22 '14 at 6:57
  • Hey but inside the sendEmail() you are sending the mail(obvious) by calling ` Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });. Wrap that code line with if (!System.Test.isRunningTest()){}` and give a try. Also make sure to do the same for any of other callouts to make sure they will not affect your test class. – highfive May 22 '14 at 7:21
  • hi thanks for reply i have warped code like this Messaging.EmailFileAttachment attch; if(!System.Test.isRunningTest()){ attch = new Messaging.EmailFileAttachment(); } but still facing same issue. – user1969206 May 22 '14 at 7:58

Can you please use the below test case and try it ?

@isTest
public class CustomizedReportControllerTest{ 
    static testMethod void TestCustomizedReportController(){    

        contact c = new contact();
        c.lastname = 'testCon';
        c.email = 'testing@tes.com';
        insert c;

        ApexPages.currentPage().getParameters().put('reportId', c.id);

        CustomizedReportController c = new CustomizedReportController();
        c.saveData();
        c.sendEmail();
    }
}
