formula in test method

Hi Guys,

 

For some reason, All my the formula value are null in my APEX test method, but works all right if I manually insert some data from user interface. Is it normal?

 

But I really need some formula value for the query condition of APEX SOQL. 

 

Thanks in advance

After you insert/update an object in test class for which you need to access its formula, you will need to query to get the value of the formula, something like this:

 

 Invoice__c inv = new Invoice__c(
            Date__c = system.today()
        );
        insert(inv);
        system.debug('before query: '+inv.testDate__c);
        Invoice__c i=[Select testDate__c from Invoice__c where Id = :inv.Id];
        system.debug('after query: '+i.testDate__c);

 

Here, testDate__c is a formula field based on the Date__c field, the first debug statement shows null, the second one shows the set value of the formula.

Hi

 

I've got the same problem, with the difference that I can't run the insert() prior to updating the formula field, because a validation rule answers false. This validation rule answers false because value of formula field is null…

 

And also, to run the trigger (on insert…), I definitely need to have a value different from null.
