Error::Hierarchy::Test

Error::Hierarchy::Test - tools to test hierarchical exceptions


NAME

Error::Hierarchy::Test - tools to test hierarchical exceptions


SYNOPSIS


  use Error::Hierarchy::Test 'throws2_ok';

  throws2_ok {

      ...

  }, 'Some::Exception',

     qr/text that \s* appears in the exception message/,

     "this test's name";


DESCRIPTION

This module provides some tools that help in testing hierarchical exceptions.


FUNCTIONS

exception_ok
Takes as arguments in the given order: an exception object, a class name, the expected content and optionally a test name.

First we check whether the exception object is of the given class type. If it is, we also check whether the stringified exception matches the expected content. If the content is a string, the content has to be equal to the stringified exception. If the content is a regex, the content has to match the stringified exception.

The first argument can also be a the Error::Hierarchy::Container manpage, in which case the first exception stored in the container will be tested.

If the test name is not given, the stringified exception is used.

Otherwise it behaves like the Test::More manpage's ok(). If the test was not ok, a diagnostic is printed.

throws2_ok
Takes as arguments in the given order: A code reference, a class name, the expected content and optionally a test name.

The code reference is executed in a try/catch block. The test is ok if the code threw the given exception, with semantics per exception_ok().

Diagnostics are printed if the exception did not match the expectations, or if no exception was thrown.
