How to Write a Test Class for SOQL and Account Field Update?
Hello, I've just started to learn about Apex and I'm having difficulty writing a test class for the following Apex class.
The following Apex class has code to retrieve Account records and logic to iterate over a list of Account records and update the Description field. I learned this Apex class through Trailhead and wanted to write a test class for it but couldn't figure out how.

public class OlderAccountsUtility {
public static void updateOlderAccounts() {
// Get the 5 oldest accounts
Account[] oldAccounts = [SELECT Id, Description FROM Account ORDER BY CreatedDate ASC LIMIT 5];
// loop through them and update the Description field
for (Account acct : oldAccounts) {
acct.Description = 'Heritage Account';
}
// save the change you made
update oldAccounts;
}
}
This is what I have written. Can anyone show me how to fix this Apex test unit so it works? Any help would be much appreciated!
@isTest
private class OlderAccountsUtilityTest {
@isTest static void createAccount() {
List <Account> accts = new List<Account>();
for(integer i = 0; i<200; i++) {
Account a = new Account(Name='testAccount'+'i');
accts.add(a);
}
insert accts;
Test.StartTest();
List<Account> accList = [SELECT Id, Description FROM Account ORDER BY CreatedDate ASC LIMIT 5];
for (Account acct : accList) {
acct.Description = 'Heritage Account';
}
Test.StopTest();
System.AssertEquals(
database.countquery('SELECT COUNT() FROM Account WHERE Description' = 'Heritage Account'), 5);
}
}
use below test class
