Vasundhara Velgoti 4 I am trying to get the coverage for the catch block as it is throwing error. Can anyone help me out
Hi ,
Below is the trigger :
trigger POTriggerUpdate on PurchaseOrder__c (after insert, after update) {
//Creating Project Plan in PurchaseOrder__c
if(((trigger.isUpdate) && trigger.isAfter) || test.isRunningTest())
{
try
{
POTriggerLogic.afterInsertAfterUpdateLogic(trigger.new,trigger.oldMap,true);
}
catch(DMLException e)
{
trigger.new[0].addError('Updation not possible because '+ e.getMessage());
}
}
//End of Update Project plan in PurchaseOrder__c
}
Test class:
@isTest
public class Test_POTriggerUpdate {

Please refer the following links that helps you throw DML Exception manually in test method to increase your Test Coverage.
Link 1 (https://salesforce.stackexchange.com/questions/130759/how-to-throw-dml-exception-manually)
Link 2 (https://salesforce.stackexchange.com/questions/101111/how-to-cause-dmlexception-delete)
You can throw exception inside your wrapper class function POTriggerLogic.afterInsertAfterUpdateLogic:
if(Test.isRunningTest() && some other condition) { throw new DMLException(); }There are several ways to invalidate DML operation. You can use any one of such techniques.
If this helps you, mark this question as solved and choose best answer so it will help other in future to judge correct solution.
