[SalesForce] Illegal assigment from LIST

I am fairly new to Salesforce, I have a trigger which requires a test method for it to meet its code coverage.

I am getting errors in the test class stating

Error: Compile Error: Illegal assignment from
LIST to Id at line 10 column 9

Trigger: PopulateHolidaysFromObject

trigger PopulateHolidaysFromObject on Opportunity (before insert,before update) {

    List<Holiday__c> HolidayList = [SELECT Name,Holiday_Date__c FROM Holiday__c];

    for(Opportunity opp : Trigger.new){

        HolidayClass holidayclass= new HolidayClass();
        opp.No_Of_Survey_Holidays__c = holidayclass.NoOfHolidays(opp.Site_Visit_Survey_Request_Date__c,opp.Site_Visit_Survey_Completed_Date__c,HolidayList);
        system.debug(opp.No_Of_Survey_Holidays__c);
        opp.No_Of_Report_Holidays__c = holidayclass.NoOfHolidays(opp.Site_Visit_Survey_Request_Date__c,opp.Scope_and_Cost_Report_Completed_Date__c,HolidayList);
        system.debug(opp.No_Of_Report_Holidays__c);        
    }
}

Test Class:

@isTest
private class TerminateServiceTest
{
    static testMethod void testTermination() 
    {
        // Setup the invoice line record
        Invoice_Line__c inv = new Invoice_Line__c();
        inv.Invoicing_Output__c = 'New Invoice';
        inv.Installation_Date__c = system.today();
        inv.Invoicing_Output__c = [SELECT id FROM Invoicing_Output__c];
        insert inv;

        // Setup service instance record
        Service_Instance__c si = new Service_Instance__c();
        si.Opportunity__c = 'New Invoice';
        si.Account__c = [SELECT id FROM Account];
        si.Airport__c = 'GAT';
        si.Contract__c = [SELECT id FROM Contract__c];
        si.Local_Service__c = [SELECT id FROM Local_Service__c];        
        si.Quantity__c = 10;
        si.Service_Start_Date__c = system.today();
        si.Service_End_Date__c = date.newInstance(2016, 8, 11);      
        si.Address__c = [SELECT id FROM Address__c];
        insert si;

        test.startTest();

        inv.Invoicing_Output__c = 'Termination Invoice';
        update inv;

        Service_Instance__c lTest = [SELECT Id, isActive__c FROM Service_Instance__c WHERE Id=:inv.Id];
        system.assertEquals(false, lTest.isActive__c );

        test.stopTest();
    }
}

Can you help me to see what is causing this error?

You are trying to set a lookup field (inv.Invoicing_Output__c) which is an ID, to a SOQL statement that returns a list of objects.

If you want to SOQL for a particular value you would do something like this.

Id myIOId = [SELECT id FROM Invoicing_Output__c].[0].Id;
inv.Invoicing_Output__c = myIOId;

This however is going to come up empty as you have not yet created an Invoicing_Output__c record. You should first create that, insert it, and then set it on the Invoice_Line__c record.

//Setup the Invoicing Output record
Invoicing_Output__c invOP = new Invoicing_Output__c();
//Set the attributes you need
insert invOP;

// Setup the invoice line record
Invoice_Line__c inv = new Invoice_Line__c();
inv.Invoicing_Output__c = 'New Invoice';
inv.Installation_Date__c = system.today();
inv.Invoicing_Output__c = invOP.Id;
insert inv;

The trigger code is having lot of redundancy, So I modified it. before posting the modified code few lines of explanation what I changed. you collected account Ids twice and did the condition check twice where once is more enough. I am also made changes to the test class, where Task data is provided which is not required because the trigger has to create it once the necessary conditions are met. I am expecting this trigger should work for you, if there is any errors feel free to post as a comment.

trigger OpportunityAfter on Opportunity (after update){

    Set AccountIDs = new Set();

    for(Opportunity o : trigger.new){
        if(opp.StageName == 'Closed - Lost' && opp.Business_Line__c == 'Workforce' && 
            opp.Survey_Type__c != 'APulse' && trigger.oldMap.get(opp.Id).StageName != opp.StageName){

                AccountIDs.add(o.AccountId);
         }
    }

    Task[] tasksToInsert = new Task[]{};

    for (Account acc : [Select Id, Name, OwnerId from Account where Id IN :AccountIds]){
        for (Opportunity opp : trigger.new){
            if(opp.AccountId == acc.Id){
                Task tas = new Task();
                tas.WhatId=acc.Id;
                tas.OwnerId=opp.OwnerId;
                tas.Subject='Follow-up: ' + opp.name + ' - ' + acc.name;
                tas.ActivityDate=(opp.CloseDate + 180);
                tas.Description='Follow up to see how engagement initiatives are going and if Avatar can help. Refer to lost opportunity: ' + opp.name;
                tasksToInsert.add(tas);                                                         
            }
        }
    }
    if(tasksToInsert != null && !tasksToInsert.isEmpty())
    Database.insert(tasksToInsert);

}

@isTest
public class TestClass {

    static testMethod void myUnitTest() {

    //Set up user
    User u1 = [SELECT Id FROM User WHERE Email='abc@sampleemail.com'];
    test.startTest();  
    //Run As U1
    System.RunAs(u1){

    System.debug('Testing trigger... (single record validation)');

    //NEW Account record
    Account acc = new account();
    acc.Name = 'Test Account';
    acc.Industry = 'Healthcare';

    insert acc;

    //NEW Opportunity record
    Opportunity opp = new Opportunity();
    opp.Name = 'Test Opportunity'; 
    opp.CloseDate = System.today();
    opp.StageName = 'S1 - Investigative';
    opp.Type = 'Repeat Business - Wrkforce HC';
    opp.AccountId = acc.Id;
    opp.Survey_Type__c = 'Product Name';

    insert opp;

    opp.StageName = 'Closed - Lost';
    opp.Reason_Won_Lost__c = 'Relationship';
    opp.Business_Line__c = 'Workforce'  //added this line to meet the if condition while collecting the set of id in the trigger.

    update opp;
   test.stopTest();
    // Here I am expecting the task has been inserted and doing a query for it         and check it in the assert statement.
   Task  testTask=[Select Id, WhatId from Task where WhatId=:acc.Id];
    //Validate single insert
    System.assertEquals(acc.Id, testTask.WhatId);

    }
    }
