Hi

I have written a trigger on sandbox. But when I am writing a test class I am getting 0% coverage.

I am posting both my trigger and test class here.

Can someone please check and tell me where I have gone wrong?

trigger CreateNewShowing on pb__Showing__c (after update) {
  integer i=1;
  for (pb__Showing__c  sh : trigger.new) {
    pb__Showing__c s = new pb__Showing__c();
   
   datetime newDate = sh.Provisional_Date_A__c;
   if(sh.Status__c == 'Pending' && sh.Provisional_Date_A__c != Null){
    s.Account__c = sh.Account__c;
    s.pb__Inventory__c = sh.pb__Inventory__c;
    s.Start_Time__c = newDate ;
    s.End_Time__c = newDate.addHours(2);
    insert s;
    }
    pb__Showing__c s1 = new pb__Showing__c();
   
    datetime newDate1 = sh.Provisional_Date_B__c;
    if(sh.Status__c == 'Pending' && sh.Provisional_Date_B__c != Null){
    s1.Account__c = sh.Account__c;
    s1.pb__Inventory__c = sh.pb__Inventory__c;
    s1.Start_Time__c = newDate1 ;
    s1.End_Time__c = newDate1.addHours(2);
    insert s1;
    }
    pb__Showing__c s2 = new pb__Showing__c();
   
    datetime newDate2 = sh.Provisional_Date_C__c;
    if(sh.Status__c == 'Pending' && sh.Provisional_Date_C__c != Null){
    s2.Account__c = sh.Account__c;
    s2.pb__Inventory__c = sh.pb__Inventory__c;
    s2.Start_Time__c = newDate2 ;
    s2.End_Time__c = newDate2.addHours(2);
    insert s2;
    }
    pb__Showing__c s3 = new pb__Showing__c();
   
    datetime newDate3 = sh.Provisional_Date_D__c;
    if(sh.Status__c == 'Pending' && sh.Provisional_Date_D__c != Null){
    s3.Account__c = sh.Account__c;
    s3.pb__Inventory__c = sh.pb__Inventory__c;
    s3.Start_Time__c = newDate3 ;
    s3.End_Time__c = newDate3.addHours(2);
    insert s3;
    }
    pb__Showing__c s4 = new pb__Showing__c();
   
    datetime newDate4 = sh.Provisional_Date_E__c;
    if((sh.Status__c == 'Pending')&&(sh.Provisional_Date_E__c != Null)){
    s4.Account__c = sh.Account__c;
    s4.pb__Inventory__c = sh.pb__Inventory__c;
    s4.Start_Time__c = newDate4 ;
    s4.End_Time__c = newDate4.addHours(2);
    insert s4;
    }
    pb__Showing__c s5 = new pb__Showing__c();
   
    datetime newDate5 = sh.Provisional_Date_F__c;
    if(sh.Status__c == 'Pending' && sh.Provisional_Date_F__c != Null){
