NAME
Assert::Refute::T::Basic - a set of most common checks for Assert::Refute suite
DESCRIPTION
This module contains most common test conditions similar to those in Test::More, like is $got, $expected; or like $got, qr/.../;.
They appear as both exportable functions in this module and Assert::Refute itself and as corresponding methods in Assert::Refute::Exec.
FUNCTIONS
All functions below are prototyped to be used without parentheses and exported by default. Scalar context is imposed onto arguments, so
is @foo, @bar;would actually compare arrays by length.
If a contract { ... } is in action, the results of each assertion will be recorded there. See Assert::Refute::Exec for more. If Test::More is in action, a unit testing script is assumed. If neither is true, an exception is thrown.
In addition, a Assert::Refute::Exec->function_name method with the same signature is generated for each of them (see Assert::Refute::Build).
is $got, $expected, "explanation"
Check for equality, undef equals undef and nothing else.
isnt $got, $expected, "explanation"
The reverse of is().
ok $condition, "explanation"
use_ok
Not really tested well.
cpm_ok $value1, 'operation', $value2, "explanation"
Currently supported: < <= == != >= > lt le eq ne ge gt
Fails if any argument is undefined.
like $got, qr/.../, "explanation"
like $got, "regex", "explanation"
UNLIKE Test::More, accepts string argument just fine.
If argument is plain scalar, it is anchored to match the WHOLE string, so that "foobar" does NOT match "ob", but DOES match ".*ob.*" OR qr/ob/.
unlike $got, "regex", "explanation"
The exact reverse of the above.
UNLIKE Test::More, accepts string argument just fine.
If argument is plain scalar, it is anchored to match the WHOLE string, so that "foobar" does NOT match "ob", but DOES match ".*ob.*" OR qr/ob/.
can_ok
isa_ok
contract_is $contract, "signature", ["message"]
Check that a contract has been fullfilled to exactly the specified extent.
See "signature" in Assert::Refute::Exec for exact signature format.
diag @message
Human-readable diagnostic message.
References are automatically serialized to depth 1.
note @message
Human-readable comment message.
References are automatically serialized to depth 1.
is_deeply( $got, $expected )
my $check = contract {
my $arg = shift;
my $expected = naive_impl( $arg );
is_deeply fast_impl( $arg ), $expected, "fast_impl ok for";
};Unlike the Test::More counterpart, prints all found discrepancies, although in a weird format. Better difference formatting wanted.
deep_diff( $old, $new )
Not exported by default. Compares 2 scalars recursively, outputs nothing if they are identical, or a (somewhat strange) in-depth summary if they differ.
