Test class coverage issue

Question

The test class below is covering the class successfully but I am getting difficulty to cover my wrapper list.

Coverage

I added data for lstPayslip in test class. I want to cover listWrapper. Getting trouble here.

my test class is as follows:

@isTest
public class DisplayPayslipControllerTest {

    //Global Variables
    private static Payslip__c objPayslip;
    private static List<Payslip__c> listPayslip;
    private static Employee__c objEmployee;
    private static Boolean Bool;

    //Data to test
    @testSetup
    public static void testData() {

        listPayslip=new List<Payslip__c>();
        objEmployee=new Employee__c(Name='TestOne',Password__c='Set@123',Mobile_Number__c='9876534563',
                                    Tech_Official_Email_ID__c='[email protected]');
        insert objEmployee;

        objPayslip=new Payslip__c(Total_Attendence__c=30,Last_Sent_Date1__c=system.now(),Sent_Date__c=system.now(),
                                  Other_Deduction__c=2000,ESIC_Monthly__c=2000,Techila_Variable__c=200,C_A__c=3000,
                                  Leave_Encashment__c=500,TDS_Monthly__c=6000,Advance_Monthly__c=6000,
                                  Opening_Balance__c=2,Leave_Availed__c=1,
                                  Techila_Basic__c=2000,PF_Employee_12_till_date__c=2000,PF_Employer_12_till_date__c=2000,
                                  Monthly_Fixed_HRA__c=5000,Food__c=1000,
                                  Fixed_Education_Allowance__c=1000,
                                  PT_Monthly__c=100,
                                  Techila_Medical_Allowance__c=3000,
                                  Monthly_PF__c=200,
                                  Techila_Year__c='2016',
                                  For_the_Month__c='JAN',Employee__c=objEmployee.id
                                // Id = ApexPages.currentPage().getParameters().get('id')
                                 );
      //  insert objPayslip;  
        system.debug('objPayslip------------->'+objPayslip);
        listPayslip.add(objPayslip);
    }

    public static testmethod void mthdDisplayPayslip() {

        testData();
        insert listPayslip;
        ApexPages.currentPage().getParameters().put('id', objPayslip.Id);

         ApexPages.StandardController sc = new ApexPages.StandardController(objPayslip); 

        //Instance of controller
           DisplayPayslipController objPaySend = new DisplayPayslipController(sc);        
           objPaySend.getrecords(); 
          // objPaySend.selectAll();          
           objPaySend.send();
           DisplayPayslipController.WrapperClass objWrapperClass=new DisplayPayslipController.WrapperClass(objPayslip,false);
    }


}

You need to set the either strSelected or strSelected1 to a non-blank, non-null value before you call your method:

objPaySend.strSelected = 'Hello World';
objPaySend.getRecords();

Make sure that the strSelected or strSelected1 variable matches the payslip record you created.

Side notes:

You can use String.isNotBlank(strSelected) instead of strSelected != null && strSelected != ''. It's a bit easier to read and quite a bit shorter, too.

You don't need to check if the list is empty before you iterate over an empty list. You can delete lines 90 and 94.

Action methods can use the void return type instead of using return null. More experienced developers tend to expect that a method might be capable of redirecting if a PageReference return type is used. This would also eliminate the need for line 96.

Change:

public PageReference getRecords() {

To:

public void getRecords() {
