Hi,

You need to modify the code and include a Test.isRunningTest() method. By this you can get the your method is running the context of Test. and You can throw the excpetion.

eg :  
if (Test.isRunningTest()) { Integer x = 1/0; // This will throw the exception. }


-Thanks

Hi AKG,

I tried the above one but it is not covering the catch block. Can you please guide me one this.
I am also facing the same issue. I tried passing wrong test records it is going to catch block but test coverage is not getting increased.


Thank you
Pradeep
