NAME

       Test2::Tools::Exception - 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($@);

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 $@, 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. $@ is preserved from before the sub is
           called when there is no exception. When an exception is trapped $@ will have the
           exception so that you can look at it.

       $bool = try_ok { ... }
       $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.

           Note: This function does not preserve $@ 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.

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.
