kann Dateierweiterung auf Testklasse nicht testen?

Question

visuaforce Seite:

<apex:page sidebar="false" controller="UploadOpportunityScheduleLineItem123"> 
    <apex:form > 
     <apex:sectionHeader title="Upload data from CSV file"/> 
      <apex:pagemessages /> 
      <center> 
       <apex:inputFile value="{!contentFile}" filename="{!nameFile}" /> 
       <apex:commandButton action="{!ReadFile}" value="Upload File" id="theButton" style="width:70px;"/> 
       <br/> <br/> 
      </center> 
    </apex:form> 
</apex:page>

     String hex = EncodingUtil.convertToHex(input); 
     System.assertEquals(0, hex.length() & 1); 
     final Integer bytesCount = hex.length() >> 1; 
     String[] bytes = new String[bytesCount]; 
     for(Integer i = 0; i < bytesCount; ++i) 
     bytes[i] = hex.mid(i << 1, 2);

Testklasse:

@IsTest(SeeAllData=true) 

    private class testexceltoaccount 
    { 
      static testmethod void testLoadData() { 
        StaticResource testdoc = [Select Id,Body from StaticResource where name ='testMethodCSVUpload1']; 
      UploadOpportunityScheduleLineItem123 testUpload = new UploadOpportunityScheduleLineItem123(); 
      testUpload.contentFile= testdoc.Body; 
      testUpload.ReadFile(); 
       } 

    } 

Cant der Lage, diesen Abschnitt des Codes in Codeabdeckung zu überqueren:

String extension = nameFile.substring(nameFile.lastIndexOf('.')+1); 
     //Checking if file extension is .csv. 
     if(extension == 'csv' ||extension == 'CSV') 
     { 

Ich habe versucht, viele mögliche Code Coverage zu überqueren, aber es ist immer noch an diesem Punkt. Bitte helfen Sie mir in dieser Hinsicht.

Vielen Dank im Voraus

Wenn wir Spitze verwenden: Eingabedatei auf VF Seite und laden Sie jede Datei, dann Name der Datei wird automatisch Feld in das Feld in Dateinamen Attribute angegeben aktualisieren, aber wenn Sie schreiben, Testklasse Sie geben nur den Inhalt der Datei an testUpload.contentFile = testdoc.Body; Sie sollen Namen in Namedatei global Variable testUpload.nameFile = 'test.csv' manuell hinzufügen;

@IsTest(SeeAllData=true) 
private class testexceltoaccount 
{ 
     static testmethod void testLoadData() { 
       StaticResource testdoc = [Select Id,Body,Name from StaticResource where name ='testMethodCSVUpload1']; 
     UploadOpportunityScheduleLineItem123 testUpload = new UploadOpportunityScheduleLineItem123(); 
     testUpload.contentFile= testdoc.Body; 
     testUpload.nameFile= 'test.csv'; 
     testUpload.ReadFile(); 
      } 

}
