如何对php method_exists()进行单元测试 [英] how to unit-test a php method_exists()
本文介绍了如何对php method_exists()进行单元测试的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
具有此代码
<?php
public function trueOrFalse($handler) {
if (method_exists($handler, 'isTrueOrFalse')) {
$result= $handler::isTrueOrFalse;
return $result;
} else {
return FALSE;
}
}
您将如何对其进行单元测试?有机会模拟$handler
吗?显然我需要某种
how would you unit-test it? is there a chance to mock a $handler
? obviously i would need some kind of
<?php
$handlerMock= \Mockery::mock(MyClass::class);
$handlerMock->shouldReceive('method_exists')->andReturn(TRUE);
但无法完成
推荐答案
好的,在您的testCase类中,您需要使用与MyClass
类相同的名称空间.技巧是覆盖当前名称空间中的内置函数.因此,假设您的课程如下所示:
Okay In your testCase class you need to use the same namespace of your MyClass
class. The trick is to override built-in functions in your current namespace. So assuming your class looks like the following:
namespace My\Namespace;
class MyClass
{
public function methodExists() {
if (method_exists($this, 'someMethod')) {
return true;
} else {
return false;
}
}
}
这是testCase类的外观:
Here is how the testCase class should look like:
namespace My\Namespace;//same namespace of the original class being tested
use \Mockery;
// Override method_exists() in current namespace for testing
function method_exists()
{
return ExampleTest::$functions->method_exists();
}
class ExampleTest extends \PHPUnit_Framework_TestCase
{
public static $functions;
public function setUp()
{
self::$functions = Mockery::mock();
}
/**
* A basic functional test example.
*
* @return void
*/
public function testBasicExample()
{
self::$functions->shouldReceive('method_exists')->once()->andReturn(false);
$myClass = new MyClass;
$this->assertEquals($myClass->methodExists(), false);
}
}
对我来说很完美.希望这会有所帮助.
It works perfect for me. Hope this helps.
