Yogesh Biyani test class to prevent deletion
I am writing a trigger to prevent detetion of certain accounts
trigger doNotDelete on Account (before delete) {
// Prevent the deletion of accounts if it is a customer
for (Account a : Trigger.old) {
if(a.Customer_ID__c!=NULL)
a.adderror('Cannot delete Active Account!');
}
}
How do I write a test class to this success of the trigger?
@isTest
public class doNotDeleteTest {
@isTest public static void
deleteTest()
{
Account a =new Account(Name='Test');
a.Customer_ID__c =1234;
insert a;
try {
delete a;
}
catch (Exception e) {
System.debug(e.getTypeName());
System.debug(e.getMessage());
}
finally {
// Something executed whether there was an error or not
}
}
}
@isTest public class doNotDeleteTest { @isTest public static void deleteTest() { Account a = new Account(Name='Test'); a.Customer_ID__c = 1234; insert a; // variable to store exception message type String exceptionType = ''; // variable to store exception message content String exceptionMessage = ''; try { delete a; } catch (Exception e) { // if there is an exception, assign its type to the new exceptionType variable exceptionType = e.getTypeName(); // if there is an exception, assign its message to the new exceptionMessage variable exceptionMessage = e.getMessage(); } // assert that the exception exists, and that its type and message are accurate System.assertEquals(exceptionType, 'System.DmlException', 'Unexpected exception type.'); System.assertEquals(exceptionMessage.contains('Cannot delete Active Account!'), true, 'Unexpected exception message.'); // validate the original Account still exists in your system List<Account> accountList = [SELECT Id FROM Account WHERE Name='Test' AND Customer_ID__c = '1234']; System.assertEquals(accountList.size(), 1, 'Unexpected Number of Accounts returned.'); } }All Answers
