public function testDatabaseConnection() { $mock = $this->getMockBuilder('Database') ->setMethods(['connect']) ->getMock(); $mock->expects($this->once()) ->method('connect') ->will($this->returnValue(true)); $result = $mock->connect(); $this->assertTrue($result); }
public function testFileSystem() { $mock = $this->getMockBuilder('FileSystem') ->setMethods(['createFile']) ->getMock(); $mock->expects($this->once()) ->method('createFile') ->with('/path/to/file.txt'); $result = $mock->createFile('/path/to/file.txt'); $this->assertNull($result); }In this example, we're creating a mock object of the FileSystem class using the getMockBuilder method. We're setting the methods that we want to mock – in this case, the createFile method – and then we're creating an expectation that the createFile method will be called once with the parameter /path/to/file.txt. Finally, we're testing that the result of the createFile method is null. The PHPUnit_Framework_TestCase getMockBuilder method is part of the PHPUnit framework, which is a package library for PHP unit testing.
