Hi there. I have an VF page which is refernced to an apex class which basically references another VF page. Need help with a test class for this.

Visual Force Page where Apex Class is referenced:
<apex:page sidebar="false" lightningStylesheets="true">
<apex:form id="theForm">
 <div align="center">
  <apex:page controller="T_Dashboards">
<b><apex:commandbutton action="{!tradersummary}" value="Trader Summary"></apex:commandbutton></b>
<b><apex:commandbutton action="{!traderbook}" value="Trader Book"></apex:commandbutton></b>
<b><apex:commandbutton action="{!creditutilizationtrader}" value="Credit Utilization - Trader"></apex:commandbutton></b>
</apex:page>

Apex Class:
public class T_Dashboards {
public PageReference tradersummary() {

        PageReference pgref = new PageReference('/apex/TraderSummary');
        pgref.setRedirect(true);
        return pgref;
    }

public PageReference traderbook() {
        PageReference pgref = new PageReference('/apex/TraderBook');
        pgref.setRedirect(true);
        return pgref;
    }

public PageReference creditutilizationtrader() {
        PageReference pgref = new PageReference('/apex/CreditUtilizationTrader');
        pgref.setRedirect(true);
        return pgref;
    }
}

Test Class:
@isTest 
public class TestTDashboards{
public static testmethod void myunitTest(){    
Test.startTest();    
PageReference pageRef = Page.T_Dashboards;  
Test.setCurrentPage(pageRef);
T_Dashboards acontroller = new T_Dashboards();
PageReference pageRef1=acontroller.tradersummary();
Test.stopTest(); 
}
}
