cmp_ok()

• Define your own comparison
• More descriptive than ok()
• More adaptable then is()

# ok( $got eq $expected );
cmp_ok( $got, 'eq', $expected, 'this eq that' );
# ok( $got == $expected );
cmp_ok( $got, '==', $expected, 'this == that' );
# ok( $got && $expected );
cmp_ok( $got, '&&', $expected, 'this && that' );
