NAME¶
Test::Mock::Guard - Simple mock test library using RAII.
SYNOPSIS¶
use Test::More; use Test::Mock::Guard qw(mock_guard); package Some::Class; sub new { bless {} => shift } sub foo { "foo" } sub bar { 1; } package main; { my $guard = mock_guard( 'Some::Class', { foo => sub { "bar" }, bar => 10 } ); my $obj = Some::Class->new; is( $obj->foo, "bar" ); is( $obj->bar, 10 ); } my $obj = Some::Class->new; is( $obj->foo, "foo" ); is( $obj->bar, 1 ); done_testing;
DESCRIPTION¶
Test::Mock::Guard is mock test library using RAII. This module is able to change method behavior by each scope. See SYNOPSIS's sample code.
EXPORT FUNCTION¶
mock_guard( @class_defs )¶
@class_defs have the following format.
- key
- Class name or object to mock.
- value
- Hash reference. Keys are method names; values are code references or scalars. If the value is code reference, it is used as a method. If the value is a scalar, the method will return the specified value.
You can mock instance methods as well as class methods (this feature was provided by cho45):
use Test::More; use Test::Mock::Guard qw(mock_guard); package Some::Class; sub new { bless {} => shift } sub foo { "foo" } package main; my $obj1 = Some::Class->new; my $obj2 = Some::Class->new; { my $obj2 = Some::Class->new; my $guard = mock_guard( $obj2, { foo => sub { "bar" } } ); is ($obj1->foo, "foo", "obj1 has not changed" ); is( $obj2->foo, "bar", "obj2 is mocked" ); } is( $obj1->foo, "foo", "obj1" ); is( $obj2->foo, "foo", "obj2" ); done_testing;
METHODS¶
new( @class_defs )¶
See "mock_guard" definition.
call_count( $class_name_or_object, $method_name )¶
Returns a number of calling of $method_name in $class_name_or_object.
