class MyTest extends PHPUnit_Framework_TestCase { function testAddition() { $result = add(2, 3); assertTrue($result == 5); } function add($a, $b) { return $a + $b; } }
class MyTest extends PHPUnit_Framework_TestCase { function testConnection() { $conn = new mysqli("localhost", "user", "password", "database"); assertTrue($conn->connect_errno == 0); } }In this example, a test case checks whether the database connection is successful by creating a new instance of the mysqli class and checking that the "connect_errno" property is equal to 0. In conclusion, PHPUnit_Framework_TestCase is an integral part of the PHPUnit testing framework for PHP. It provides developers with a way to create automated unit tests that can ensure their code is working as intended. The package library name is PHPUnit.
