easy mock php,FBMock: FBMock 是一个简单易用的 PHP 模拟测试框架 （PHP Mocks Framework）...
FBMock
FBMock is a PHP mocking framework designed to be simple and easy to use.
Unlike other mocking frameworks, FBMock is basically just stubs with spies. Instead of using a custom DSL and relying on opaque tear-down verification, FBMock encourages developers to program simple return behaviors and only use spies when appropriate.
Requirements
HHVM or PHP 5.4+
Note: the framework's tests use PHPUnit but PHPUnit is not necessary for using FBMock.
Usage
Include init.php which sets up the autoloader
require_once YOUR_FBMOCKS_DIR.'/init.php'
Install using Composer (optional)
To install this package via composer, just add the package to require and start using it.
{
"require":{
"facebook/fbmock":"*@dev"
}
}
Creating a mock
mock('Foo')
Also, you can mock an interface in the same manner:
mock('IFoo')
Stubbing
By default, all methods return null. Helper methods for configuring return values are prefixed with 'mock'.
mock('Foo')->mockReturn('bar', 'return value here');
Sometimes, you need more control than mockReturn:
mock('Foo')->mockImplementation(
'bar',
function ($bar_type) {
return $bar_type == 1;
}
);
For other helpers (mockThrow, mockReturnThis, etc.) see Mock.php
Spying
$mock_foo = mock('Foo');
$mock->mockReturn('bar', 1);
$code_under_test->doSomething($mock_foo);
// Returns array of calls
$mock_foo->mockGetCalls('bar');
If you are using PHPUnit, you can add FBMock_AssertionHelpers to your base PHPUnit_TestCase to get some spying helpers:
$this->assertCalledOnce($mock_foo, 'bar');
$this->assertCalledOnce($mock_foo, 'bar', $expected_params_as_array); // param assertion is optional
$this->assertCalls($mock_foo, 'bar', $expected_params_for_first_call, $expected_params_for_second_call, ...);
Tips
Use multiset capabilities to improve legibility
mock('Foo')->mockReturn(array(
'bar' => 1,
'get' => 'data',
'run' => true,
))->mockReturnThis('set', 'addID', 'removeID');
Utilize the fluent interface for concise mock setup.
mock('Foo')
->mockReturn('bar', 1)
->mockThrow('other_method')
->mockImplementation('another_method', function () { /* ... */ })
->mockReturnThis('setData');
Use strict mocks when it's critical a method isn't called
If any unmocked method is called, the mock will throw.
$db_conn = strict_mock('DBConnection')->mockReturn('read', $data);
// ...in code under test
$db_conn->write($some_data); // Throws FBMock_MockFrameworkException
Customizing
See CustomConfig-sample.php for instructions on customizing FBMock for your needs.
HHVM-only features
Mock final classes and classes with final methods
Mock internal classes
