                                      Class<? extends Throwable> type)
Asserts that the actual Throwable type is an the same as the given type.

Parameters:
info - contains information about the assertion.
actual - the given Throwable.
type - the type to check the actual Throwable against.
Throws:
AssertionError - if the actual Throwable is null.
AssertionError - if the actual Throwable is not an instance of the given type.
NullPointerException - if the given type is null.

assertHasMessage

public void assertHasMessage(AssertionInfo info,
                             Throwable actual,
                             String message)

info - contains information about the assertion.
actual - the given Throwable.
message - the expected message.
Throws:
AssertionError - if the actual Throwable is null.

Parameters:
info - contains information about the assertion.
actual - the given Throwable.
