>>220 の使い方です。

- assert(bool, [message])
- set_up, tear_down は、他のTestUnit framework と同等。
- test runner は付いてないので、自分で実行しないといけない。->run;

new MyTest->run;
{package MyTest;
use base qw/Unit7/;
sub new { shift()->SUPER::new(@_) }
sub set_up { my($self)=@_; $self->{val} = 0 }
sub tear_down { my($self)=@_; undef $self->{val} }
sub test_foo {
my($self)=@_;
$self->assert(defined $self->{val}, "defined val");
$self->assert(!$self->{val}, "! val");
$self->assert(0==$self->{val}, "0 == val");
$self->assert('0' eq $self->{val}, "'0' eq val");
}
sub test_bar {
my($self)=@_;
$self->{val} = 1000;
$self->assert(1000 < $self->{val}, "1000 < val"); # failure
$self->assert(1000 <= $self->{val}, "1000 <= val");
$self->assert(1000 == $self->{val}, "1000 == val");
$self->assert(1000 > $self->{val}, "1000 > val"); # failure
$self->assert(1000 <= $self->{val}, "1000 >= val");
}
}
