Test2::Tools::Exception(3) Test2 based tools for checking exceptions

DESCRIPTION

This is the Test2 implementation of code used to test exceptions. This is similar to Test::Fatal, but it intentionally does much less.

SYNOPSIS


use Test2::Tools::Exception qw/dies lives/;
like(
dies { die 'xxx' },
qr/xxx/,
"Got exception"
);
ok(lives { ... }, "did not die") or note([email protected]);

EXPORTS

All subs are exported by default.
$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 [email protected], it will not be altered from its value before the sub is called.
$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. [email protected] is preserved from before the sub is called when there is no exception. When an exception is trapped [email protected] will have the exception so that you can look at it.

DIFFERENCES FROM TEST::FATAL

Test::Fatal sets $Test::Builder::Level such that failing tests inside the exception block will report to the line where "exception()" is called. I disagree with this, and think the actual line of the failing test is more important. Ultimately, though Test::Fatal cannot be changed, people probably already depend on that behavior.
