=head1 NAME
Test2::Tools::Exception - Test2 based tools for checking exceptions
=head1 DESCRIPTION
This is the L<Test2> implementation of code used to test exceptions. This is
similar to L<Test::Fatal>, but it intentionally does much less.
=head1 SYNOPSIS
use Test2::Tools::Exception qw/dies lives/;
like(
dies { die 'xxx' },
qr/xxx/,
"Got exception"
);
ok(lives { ... }, "did not die") or note($@);
=head1 EXPORTS
All subs are exported by default.
=over 4
=item $e = dies { ... }
This will trap any exception the codeblock throws. If no exception is thrown
the sub will return undef. If an exception is thrown it will be returned. This
function preserves C<$@>, it will not be altered from its value before the sub
is called.
=item $bool = lives { ... }
This will trap any exception thrown in the codeblock. It will return true when
there is no exception, and false when there is. C<$@> is preserved from before
the sub is called when there is no exception. When an exception is trapped
C<$@> will have the exception so that you can look at it.
=item $bool = try_ok { ... }
=item $bool = try_ok { ... } "Test Description"
This will run the code block trapping any exception. If there is no exception a
passing event will be issued. If the test fails a failing event will be issued,
and the exception will be reported as diagnostics.
B<Note:> This function does not preserve C<$@> on failure, it will be set to
the exception the codeblock throws, this is by design so that you can obtain
the exception if desired.
=back
=head1 DIFFERENCES FROM TEST::FATAL
L<Test::Fatal> sets C<$Test::Builder::Level> such that failing tests inside the
exception block will report to the line where C<exception()> is called. I
disagree with this, and think the actual line of the failing test is
more important. Ultimately, though L<Test::Fatal> cannot be changed, people
probably already depend on that behavior.
