Mocking global functions or static methods is a common but difficult problem when doing PHP unit testing. Recently in a project, I encountered the need to mock some global functions in unit tests to isolate the test environment and ensure the accuracy of the test results. However, PHP itself does not provide direct emulation, which is very bothering me.

After trying multiple methods, I found the library php-mock/php-mock-integration, which is a package that provides integrated support for PHP-Mock. This library can be seamlessly integrated with a variety of test frameworks, including PHPUnit, Mockery, and Prophecy (phptpect), greatly simplifying my testing efforts.

Installing php-mock/php-mock-integration using Composer is very simple, just run the following command:

 <code>composer require php-mock/php-mock-integration</code>

Next, I will explain how to use this library to integrate with PHPUnit. First, you need to install the php-mock/php-mock-phpunit package:

 <code>composer require --dev php-mock/php-mock-phpunit</code>

Then, in your test class, you can use Mockery or Prophecy to mock global functions. For example, use Mockery to simulate time() function:

 <code class="php">use phpmock\phpunit\PHPMock; use PHPUnit\Framework\TestCase; class MyTest extends TestCase { use PHPMock; public function testTime() { $time = $this->getFunctionMock('MyNamespace', 'time'); $time->expects($this->once()) ->willReturn(1234567890); $this->assertEquals(1234567890, time()); } }</code>

By using php-mock/php-mock-integration, I was able to easily mock global functions and static methods in unit tests, ensuring isolation of the test environment and accuracy of the test results. This library not only simplifies my testing work, but also improves the efficiency and reliability of the testing.

Overall, php-mock/php-mock-integration is a very useful tool, especially for developers who need to mock in PHP unit tests. If you encounter similar needs, you might as well try this library, which will make you more comfortable in testing.
