NAME¶
Test::Exception::LessClever - Test::Exception simplified
DESCRIPTION¶
An alternative to Test::Exception that is much simpler. This alternative does
not use fancy stack tricks to hide itself. The idea here is to keep it simple.
This also solves the Test::Exception bug where some dies will be hidden when a
DESTROY method calls eval. If a DESTROY method masks $@ a warning will be
generated as well.
WHY REWRITE TEST-EXCEPTION¶
Here is an IRC log.
<Exodist> wtf? Bizarre copy of HASH in sassign at /usr/lib64/perl5/5.10.1/Carp/Heavy.pm line 104
<Exodist> hmm, it doesn't happen when I step through the debugger, that sure is helpful yessir
<Exodist> hmm, throws_ok or dies_ok { stuff that croaks in a package used by the one being tested }, at least in this case causes that error. If I change it to eval {}; ok( $@ ); like( $@, qr// ); it works fine
<Exodist> Ah-Ha, earlier when I mentioned I stopped using throws_ok because of something I could not remember, this was it, I stumbled on it again!
<confound> probably because throws_ok tries to do clever things to fiddle with the call stack to make it appear as though its guts are not being called
<confound> less clever would be more useful
SYNOPSYS¶
Pretty much a clone of Test::Exception Refer to those docs for more details.
use Test::More;
use Test::Exception;
dies_ok { die( 'xxx' )} "Should die";
lives_ok { 1 } "Should live";
throws_ok { die( 'xxx' )} qr/xxx/, "Throws 'xxx'";
lives_and { ok( 1, "We did not die" )} "Ooops we died";
done_testing;
EXPORTABLE FUNCTIONS¶
- $status = live_or_die( sub { ... }, $name )
- ($status, $msg) = live_or_die( sub { ... }, $name )
- Check if the code lives or dies. In scalar context returns true or false.
In array context returns the same true or false with the error message. If
the return is true the error message will be something along the lines of
'did not die' but this may change in the future.
Will generate a warning if the test dies, $@ is empty AND called in array
context. This usually occurs when an objects DESTROY method calls eval and
masks $@.
*NOT EXPORTED BY DEFAULT*
- lives_ok( sub { ... }, $name )
- Test passes if the sub does not die, false if it does.
- dies_ok( sub { ... }, $name )
- Test passes if the sub dies, false if it does not.
- throws_ok( sub { ... }, qr/message/, $name )
- Check that the sub dies, and that it throws an error that matches the
regex.
Test fails is the sub does not die, or if the message does not match the
regex.
- lives_and( sub {...}, $name )
- Fails with $name if the sub dies, otherwise is passive. This is useful for
running a test that could die. If it dies there is a failure, fi ti lives
it is responsible for itself.
