NAME
Test::EasyMock - A mock library which is usable easily.
SYNOPSIS
use Test::EasyMock qw(
create_mock
expect
replay
verify
reset
);
my $mock = create_mock();
expect($mock->foo(1))->and_scalar_return('a');
expect($mock->foo(2))->and_scalar_return('b');
replay($mock);
$mock->foo(1); # return 'a'
$mock->foo(2); # return 'b'
$mock->foo(3); # Unexpected method call.(A test is failed)
verify($mock); # verify all expectations is invoked.
reset($mock);
expect($mock->foo(1, 2)->and_array_return('a', 'b');
expect($mock->foo({ value => 3 })->and_array_return('c');
replay($mock);
$mock->foo(1, 2); # return ('a', 'b')
$mock->foo({ value => 3 }); # return ('c')
verify($mock);
reset($mock);
expect($mock->foo(1))->and_scalar_return('a');
expect($mock->foo(1))->and_scalar_return('b');
replay($mock);
$mock->foo(1); # return 'a'
$mock->foo(1); # return 'b'
$mock->foo(1); # Unexpected method call.(A test is failed)
verify($mock);
DESCRIPTION
This is mock library modeled on 'EasyMock' in Java.
FUNCTIONS
create_mock([$module_name|$object])
Creates a mock object. If specified the $module_name then a isa($module_name) method of the mock object returns true.
expect($expectation)
Record a method invocation and behavior.
The following example is expecting the foo method invocation with $arguments and a result of the invocation is 123.
expect($mock->foo($arguments))
->and_scalar_return(123);
And the next example is expecting the foo method invocation without an argument and a result of the invocation is (1, 2, 3).
expect($mock->foo())
->and_array_return(1, 2, 3);
A list of and_* methods.
- and_scalar_return($value)
-
Add scalar result to the expectation.
- and_array_return(@values)
-
Add array result to the expectation.
- and_die([$message])
-
Add die behavior to the expectation.
- and_stub_scalar_return($value)
-
Set scalar result as a stub to the expectation.
- and_stub_array_return(@values)
-
Set array result as a stub to the expectation.
- and_stub_die([$message])
-
Set die behavior as as stub to the expectation.
replay($mock [, $mock2 ...])
Replay the mock object behaviors which is recorded by the expect function.
replay($mock);
verify($mock)
Verify the mock method invocations.
reset($mock)
Reset the mock.
