Java转换为php？

Question

Is it possible to convert this java code snippet to php?

public void testBalanceReturnsToZeroOnVending()
        {
            sodaVendor.insertCoin(50);
            sodaVendor.insertCoin(20);
            sodaVendor.insertCoin(5);
            // The price is right!
            assertEquals("We have entered correct money", 
                SODA_PRICE,
                sodaVendor.getCurrentBalance());
            sodaVendor.dispenseItem();
            assertEquals("After vending, the balance of soda vending machine is zero", 
                0,
                sodaVendor.getCurrentBalance());
        }

Answer 1

Assuming PHPUnit is your unit testing framework:

<?php
require_once 'PHPUnit/Framework.php';
// require the file containing the class that sodaVendor is an instance of

define('SODA_PRICE', 75);

class SodaVendorTest extends PHPUnit_Framework_TestCase {
    private $sodaVendor;

    public function setUp() {
        // set up $this->sodaVendor somehow...
    }

    public function tearDown() {
        $this->sodaVendor = null;
    }

    public function testBalanceReturnsToZeroOnVending() {
        $this->sodaVendor->insertCoin(50);
        $this->sodaVendor->insertCoin(20);
        $this->sodaVendor->insertCoin(5);
        // The price is right!
        $this->assertEquals(SODA_PRICE,
            $this->sodaVendor->getCurrentBalance(),
            "We have entered correct money");
        $this->sodaVendor->dispenseItem();
        $this->assertEquals(0,
            $this->sodaVendor->getCurrentBalance(),
            "After vending, the balance of soda vending machine is zero");
    }
}
?>
