Help writing a test class for my trigger

Hello!

I'm new to writing apex triggers but I finally got one to work in my sandbox.  My problem now is that I can't put it inot production without a test class, and I'm clueless on how to write it.  Here is what I'm trying to do:

 

When a Lead is created links via a lookup to a custom object called Site; When the field "First Payment Date" on the Site is updated the trigger updats a field named "First Payment Date" on the Lead.

 

How the heck do I write a test class for this??  Any help would be greatly appreciated!!

Hi ,

 

try this:

 

@isTest 
private class updateFirstPaymentDateTest{
    static testMethod void firstPaymentTest() {
        lead l = new lead();
        l.name = 'test Leads';
        //add all the necessary / required fields.
        insert l;
        
        site__c s = new site__c();
        s.name = 'test';
        s.First_Payment_Date__c = system.today();
        s.lead__c = l.id;
        //add all the necessary / required fields.
        insert s;
    }
}

 Hope it helps!

Hi Sam,

First - thanks so much for your help.  I tried out the class but am having 1 problem, I got this error when I tried save the class:

 

Error: Compile Error: Field is not writeable: Lead.Name at line 5 column 9

 

I'm not sure why the Lead.Name wouldn't be writable, but any suggestion on what else I can try?

Sam - thanks again for your help.  With some tinkering I figured it out!  Here is how the test class look now:

 

@isTest 
private class updateFirstPaymentDateTest{
    static testMethod void firstPaymentTest() {
        lead l = new lead();
        l.lastname = 'test Leads';
        l.company = 'test company';
        //add all the necessary / required fields.
        insert l;
        
        site__c s = new site__c();
        s.First_Payment_Date__c = system.today();
        s.lead__c = l.id;
        //add all the necessary / required fields.
        insert s;
    }
}

 

 

Thanks again for the help!

Hello!  I am having the same issues.  I am ok at writing triggersbut I cannot get my test class to work correctly.  Any help would be appreciated!  Here is the trigger.

 

Trigger updateRelatedOpportunity on dsfs__DocuSign_Status__c(after update){

List<Id> oppIds = new List<Id>();
for(dsfs__DocuSign_Status__c dc:trigger.new){
if(dc.dsfs__Completed_Date_Time__c<>NULL){ 
oppIds.add(dc.dsfs__Opportunity__c); 

}
}

List<Opportunity> oppList = [select StageName from Opportunity where id in:oppIds];
List<Opportunity> oppListnew = new List<Opportunity>();

for(Opportunity op : oppList){
op.StageName='Closed Won';
oppListnew.add(op);
}
update oppListnew;
 
}

Soooo close!  It looks like I am still getting an error of Illegal Assignment from id to SOBJECT:Account at line 11 column 9

 

public class YourTriggerTestClass{
static testMethod void yourTestMethod(){
//insert account
account acc = new account();
acc.name='test account';
//fill all the required field and make sure your data passes the validation rules.
insert acc;

opportunity opp = new opportunity();
opp.name = 'Test oppty';
opp.account = acc.id;
opp.Project_Type__c='Semedica';
opp.CloseDate=system.today();
//fill all the required field and make sure your data passes the validation rules.
insert opp;

dsfs__DocuSign_Status__c dsfs = new dsfs__DocuSign_Status__c ();

dsfs.dsfs__Completed_Date_Time__c = system.today();
dsfs.dsfs__Opportunity__c = opp.id;
insert dsfs;

dsfs.dsfs__Completed_Date_Time__c = system.today().addDays();
update dsfs;
}
}

 

 

 

Thank you so much for your help so far!  Do you why this error would occur?  Again thanks a ton for your help!

So I was able to get my class to save correctly!  WHOOOO HOOO!  However I am now running into 0% percent coverage for my class. and I need to get that bad boy up to 75%.  here is the finished code

 

public class YourTriggerTestClass{
    static testMethod void yourTestMethod(){
        //insert account
        account acc = new account();
        acc.name='test account';
        //fill all the required field and make sure your data passes the validation rules.
        insert acc;
        
        opportunity opp = new opportunity();
        opp.name = 'Test oppty';
        opp.Project_Type__c='Semedica';
        opp.StageName='Qualified';
        opp.CloseDate=system.today();
        //fill all the required field and make sure your data passes the validation rules.
        insert opp;
        
        dsfs__DocuSign_Status__c  dsfs = new dsfs__DocuSign_Status__c ();
        
        dsfs.dsfs__Completed_Date_Time__c = system.today();
        dsfs.dsfs__Opportunity__c = opp.id;
        insert dsfs;
        
        dsfs.dsfs__Completed_Date_Time__c = system.today();
        update dsfs;
    }
}

Hi?

Just add the @isTest annotation in the 1st line. This should solve the issue. Something like this:

@isTest
public class YourTriggerTestClass{
