Hi Hemika,
It does not matter. You can have "expectedExceptions" attribute with any
exception class when the method signature throws Exception class. Cause
expectedExceptions will check the instance of thrown exception class with
the exception class defined with expectedExceptions. Below sample test
method will marked as passed.
@Test( expectedExceptions = {*IOException*.class})
public void testMethod() throws *Exception* {
.........
throw new *IOException*("File Not Found");
}
Thanks,
Nuwanw
