=head1 NAME

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

=head1 VERSION

version 1.103530

=head1 SYNOPSIS

  throws2_ok {
      # ...
  }, 'Some::Exception',
     qr/text that \s* appears in the exception message/,
     "this test's name";

=head1 DESCRIPTION

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

=head1 FUNCTIONS

=head2 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 L<Error::Hierarchy::Container>, 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 L<Test::More>'s C<ok()>. If the test was not ok, a
diagnostic is printed.

=head2 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 C<try>/C<catch> block. The test is ok if
the code threw the given exception, with semantics per C<exception_ok()>.

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