How would I write a test class for this very simple Custom controller?

public class OpportunityController {
    
    public List<Opportunity> opp {get;set;}

    public OpportunityController() {
        opp = [SELECT Id, Name, CreatedDate, StageName, Placement__c, LDN_Company__c, Description, Job_Title__c, CloseDate, 
				NextStep, Salary__c, Future_Prospects__c, Duration__c, Training_Delivery_Site__c, Qualification_taken__c, Entry_Requirements__c, Key_Responsibilities__c, 
				Skills_Required__c, Account.Name, Account.BillingPostalCode, Account.BillingStreet, Account.BillingCity FROM Opportunity 
				WHERE (StageName = '1 - Qualifying' or StageName = '2 - Booked for CK' or StageName = '3 - Live'
               or StageName = '4 - Work Trial') AND (Placement__c = 'New Apprentice')];
        	}
}

I can't figure out how to approach it for a custom and not standard controller

Thank you

Hi Matthew,

Greetings to you!

Please try the below code:
@isTest
private class Test_OpportunityController {	
    @isTest
    static testMethod void oppList(){
        
        Opportunity o = new Opportunity();
        o.Name='Test Name';
        o.StageName='1 - Qualifying';
        o.CloseDate = System.today();
        o.Placement__c='New Apprentice';
        // Add other required fields
        INSERT o;
        
        Test.startTest();

        OpportunityController oc = new OpportunityController();
        Opportunity o2 = [SELECT Id, Name, CreatedDate, StageName, Placement__c, LDN_Company__c, Description, Job_Title__c, CloseDate, 
				NextStep, Salary__c, Future_Prospects__c, Duration__c, Training_Delivery_Site__c, Qualification_taken__c, Entry_Requirements__c, Key_Responsibilities__c, 
				Skills_Required__c, Account.Name, Account.BillingPostalCode, Account.BillingStreet, Account.BillingCity FROM Opportunity 
				WHERE (StageName = '1 - Qualifying' or StageName = '2 - Booked for CK' or StageName = '3 - Live'
               or StageName = '4 - Work Trial') AND (Placement__c = 'New Apprentice')];

        Test.stopTest();

        System.assert(o2!=null);        
    }    
}

I hope it helps you.

You are asking a question about the exact same test class in two different posts.  Please limit your question to one post.

Duplicate post.
